Frequently Asked Questions - Cadis HK AUDIO

How do I connect multiple CAD 208 enclosures?

Use two Speakon NL4 connectors per enclosure wired in parallel. Connect the amplifier output to the input of the first enclosure, then daisy-chain to subsequent enclosures using the through connector. Ensure correct pin assignments: pin 1+ for mid/high, pin 2+ for sub (if used).

What is the maximum number of CAD 208 enclosures I can fly?

Up to 20 enclosures in a stacked array with TÜV certification. The total weight of 20 enclosures is 350 kg (771.6 lbs), plus 11.5 kg for the rigging frame. Exceeding this voids certification.

Can I mix CAD 115 subwoofers with CAD 208 enclosures in a flown system?

Yes. For example, fly 1 CAD 115 Sub + 10 CAD 208 or 2 CAD 115 Subs + 8 CAD 208 on a single rigging frame. Maximum two subwoofers in combination with the connector frame.

How do I adjust the set angle between CAD 208 enclosures?

Two modes: Compression mode (adjustable after hoisting using a lashing strap) and Fixed mode (set during assembly). Angles from 0° to 15° in 1.5° steps are available via quick-release pins.

What type of amplifier should I use with the CADIS system?

Recommended amplifiers: HK AUDIO VX 2400 or Lab.gruppen FP 10000Q. Set the FIRNET controller's Max Output Level accordingly: +6 dB for VX 2400, +18 dB for FP 10000Q.

How do I load filter sets for the FIRNET controller?

Connect PC to FIRNET via Ethernet, install LIPAN software from the CD-Rom, then load the appropriate filter bank (e.g., CAD208-8 fullr for 8 x CAD 208) using the Update Scene + Filter Libraries dialog.

What maintenance is required for the CADIS rigging hardware?

Inspect all quick-release pins, connectors, and rigging frames for cracks or deformation before each use. Annual inspection by a qualified expert is required per VBG 9a. For mobile use, inspect every six months. Replace damaged parts with original HK AUDIO components.

How do I replace the 8" woofer in a CAD 208 enclosure?

Remove the grille, side panels, and baffle board. Unscrew the woofer's Torx T25 screws, disconnect wires, and install the replacement (part #9940261). Ensure correct polarity: red wire is positive (+). Reassemble in reverse order.

What is the correct way to ground stack the CADIS system?

Place the standard rigging frame on a stable surface with rubber feet down. Mount CAD 208 enclosures upside-down (rigging hardware facing up) and tilt the stack downward up to 7.5° using fixed mode angles. Secure the stack with lashing straps to prevent slippage.

How do I clean the CADIS enclosures?

Use only a dry cloth to clean the cabinet surfaces. Do not use water, solvents, or abrasive cleaners. For the front grille, gently vacuum or use a soft brush. Avoid exposing the system to moisture.

A CADIS™ Speaker Cabinets

1 CAD 208 Mid/High Enclosure

Black rectangular electronic device with perforated top panel and side connectors (no visible text or symbols)

Fig. 1: CAD 208

Design and Construction

The CAD 208 mid/high enclosure's top and bottom panels are sloped at an angle of 7.5^ . The housing is made of polyamide resin reinforced with glass fibers, a tough, rugged, and weatherproof plastic exceptionally well-suited for constructing loudspeaker enclosures. When configured in a 0^ array, each cabinet may be tilted up to 15^ measured from the next higher rigging point, in 1.5^ steps. The baffle board covering consists of a metal grilled backed with two 8" speakers and the horns fed by the two 1" drivers.

The (passive) CAD 208 unit weighs 17.5 kg. It is 57.8 cm wide, 37.3 cm high and 27.2 cm deep (including rigging hardware).

Fully integrated rigging hardware serves to fly the mid/high units. It consists of four quick-release pins and three rigging connectors, two mounted on the sides and one on the back panel.

Electrical and Acoustical Data

The CAD 208 enclosure is loaded with two 8" cone chassis speakers and two 1" high frequency drivers feeding CD horns. An internal passive crossover addresses the drivers. The separating frequency for the HF drivers is 2,200 Hz.

The CAD 208 enclosure's nominal electrical power-handling capacity is 500 watts program (AES signal, 6 dB crest) at 16 ohms overall impedance. It produces a sound pressure level of 101 dB (1W@1m), measured under half-space conditions. Maximum SPL measured under the same conditions at a distance of one meter is 136 dB at 10% THD.

The enclosure radiates sound at a horizontal angle of 100^ and a vertical angle of 15%. Frequency response ranges from 100 Hz to 20 kHz ( ±3 dB).

Note: The bottom threshold frequency can drop to 70 Hz, depending on the height of the array.

The CAD 208 is thus able to serve as a fullrange speaker for pure speech reinforcement applications. We recommend using at least two enclosures for this.

Connections

The connector panel on the rear of the CAD 208 is recessed to protect the ports from harm. This enclosure may be equipped with three types of connectors:

a: Connector panel with two Speakon NL 4 ports (Input/Through)

Both ports' four pins are wired in parallel. Pin assignments are pin 1+ = mid/high +, 1- = mid/ high -, 2+ = sub +, 2- = sub 2-.

b: Connector panel with binding posts

for tri-amped (without internal crossover, with external controller) or passive (internal crossover network) and operating modes - optional

c: Connector panel with PG glands

Fig. 2 Subwoofer CAD 115 Sub

Design and Construction of the Subwoofer

Made of 18-mm, 13-ply birch plywood, the CAD 115 Sub enclosure is coated with water-repellent, black acrylic enamel. The baffle board cover consists of a metal grille. The CAD 115 Sub weighs 38 kg. It is 58.3 cm wide, 57.3 high and 64 cm deep. Two slot grips have been routed into the side panels for easy transport and set-up.

Electrical and Acoustical Data

The CADIST™ 115 Sub enclosure is loaded with one 15" woofer. The CAD 115 Sub enclosure's nominal electrical power-handling capacity is 600 watts RMS at 8 ohms impedance. It produces a sound pressure level of 102 dB (1W@1m), measured under half-space conditions. Maximum SPL measured under the same conditions at a distance of one meter is 122 dB at 10% THD. The frequency response of the CAD 115 Sub ranges from 47Hz to 150 Hz (±3 dB).

Connections

The connector panel on the rear of the CAD 115 Sub enclosure is recessed to protect the ports from harm. On this enclosure, you'll find two Speakon NL4 connectors. Both ports' four pins are wired in parallel. Pin assignments are pin 1+ = mid/high +, 1- = mid/high -, 2+ = sub +, 2- = sub 2 .

Important Notes on Safety!

Original CADIST™ rigging accessories have been certified as a complete and cohesive system by the safety standards authority TÜV. The rigging system's provisions for use require that it be installed in accordance with the following specifications. Before you begin installation, ensure that the rigging points (for example, a chain hoist) on the stage roof or the venue's ceiling comply with BGV-C1 accident prevention regulations and that the safety standards authority TÜV has certified them for the full load (see table 1). Prior to every installation, inspect all components to ensure they are in good operating condition, taking particular care to confirm that all quick-release pins and hardware connectors are undamaged.

The principle requirement for safe handling and trouble-free operation of rigging frames is a thorough understanding of fundamental operating safety and safety regulations.

This manual contains important instructions on how to safely use rigging frames.

2.1 Responsibilities of the Operator

As the operator, you are obligated to allow only those persons to work with rigging frames who are:

• 16 years of age or older,
- physically and mentally able, familiar with the basic rules of industrial safety and accident prevention, and trained in the handling of rigging frames.

Regularly review and confirm personnel's work safety awareness. In addition, task personnel with specific responsibilities for setting up, putting into service, operating, maintaining, and repairing equipment. Ensure that personnel are trained to work with the rigging frame only under the supervision of a proficient and experienced technician. Ensure also that defects, flaws and other damage that could impede safety are repaired immediately.

2.2 Storage, Maintenance, Inspection and Repair of CADIS™ Rigging Hardware

Storage and safekeeping when not in use

When not in use store the rigging frame in a safe place where it cannot be tipped over and is protected from exposure to the elements.

Inspections

§ 39, VBG ga of the German employers' liability insurance association's accident prevention regulations requires that load-carrying equipment be inspected by a qualified expert and possible defects be eliminated prior to initial commissioning by the recipient.

§ 40, VBG 9a requires that load-carrying equipment be inspected at least annually for cracks.

Additionally, equipment used in mobile applications where it is frequently set up and torn down must be inspected for cracks every six months.

Maintenance

You are authorized to replace easily serviceable wearing or standard parts in accordance with the manufacturer's instructions. Use original parts for this purpose.

Tighten screws and bolted connections whenever necessary.

Repair

In the event that parts of the load-carrying equipment have been deformed, it is up to the manufacturer to determine if they are repairable.

Solely the manufacturer is authorized to perform welding and repair jobs on load-carrying equipment.

2.3 Technical Specifications of CADIS™ Rigging Hardware

Load-carrying capacity of the rigging frame: 400 kg / 881.9 lbs.

Test load: 2,500 kg / 5,512 lbs.

Ambient temperature when in operation: min. -10^ C, max. +60^ C

2.4 Maximum Number of Flown CAD 208 Mid/High Enclosures

Caution: Flying more than 20 enclosures in a stacked array voids the safety standards authority TÜV's certification!

Refer to table 1 to determine flown loads. The sum of the weights of CADISTM enclosures plus the weight of the rigging frames equals the total load.

Note: Ensure that you add the weights of chain hoists, motors, cables and further stops to determine total weight!

• 1x CAD 115 Sub + 10 CAD 208

• 2x CAD 115 Sub + 8 CAD 208

Caution: Flying more than two subwoofers in stacked array with the connector frame voids the safety standards authority TÜV's certification!

CAD 115 subwoofers and CAD 208 mid/high enclosures may also be flown together on one rigging frame. Refer to table 2 to determine flown loads. The sum of the weights of CADISTM subwoofers and mid/high enclosures plus the weight of the rigging frames equals the total load.

Note: Ensure that you add the weights of chain hoists, motors, cables and further stops to determine total weight!

Weight of the standard rigging frame with shackles: 11.5 kg/25.35 lbs.

2.6 Pick-points for Flying CADIS ^™ Enclosures

Use only the rigging frame's shackles to attach motors, chain hoists and straps, inserting them into the holes in the center rod! Clear the area immediately below arrays of people before raising or lowering loads. Hoist and lower flown enclosures smoothly, avoiding abrupt stops or jerky motions. Secure the flown array with straps to prevent it from moving, for example, in the event of gusting winds.

2.7 Structural Modifications of CADIS™ Rigging Hardware

No structural modifications may be made without the manufacturer's consent. This also applies to welding work performed on load-bearing parts. Structural alterations require the manufacturer's written approval. Use original replacement and wearing parts only.

2.8 Original HK AUDIO Accessories

Use original HK AUDIO parts only (see chapter 3). The safety standards authority TÜV has not certified any other parts for use. Always install parts in accordance with these installation instructions. Compile and store all documents pertaining to the system in a safe place.

2.9 Initiation and Operation

§ 39, VBG 9a of the German employers' liability insurance association's accident prevention regulations requires that load-carrying equipment be inspected by a qualified expert and possible defects be eliminated prior to initial commissioning by the recipient.

§ 41 VBG 9a requires that load-carrying equipment be subjected to a non-routine inspection following damage, repair work and other incidents that can affect load-carrying capacity.

3 Flown Applications and Components of CADIS™ Rigging Hardware

Fig. 4: 8 flown CAD 208 mid/high enclosures

CADISTM rigging hardware consists of the following parts:

• a standard rigging frame with two shackles for attaching motors, lashing straps or chain hoists. The rigging frame also serves as the base for ground stacks.
• an optional two-part lashing strap for curving the array in compression mode
• integrated rigging hardware on the side and back for flying CADIST™ enclosures
• four quick-release pins per CAD 208 for connecting the enclosure to another enclosure or the rigging frame (eight 17-mm QRP)
• connectors for mounting the CAD 115 Sub to the rigging frame
• rigging yoke for mounting the CAD 208 below the CAD 115 Sub

Important note on pins: Quick-release pins serve to connect rigging hardware and speaker enclosures, and their proper function must be tested and verified. The pins must always engage fully in the (fitted) hole. Under no circumstances may these pins release on their own when subjected to tractional forces. The nib in the center of the pinhead must always be depressed to insert pins; it releases the ball detents in front. Once the pin engages in the hole, the nib must glide back to its initial position.

4 Adjusting the Set Angle between Two CAD 208 Mid/High Enclosures

You have two options for adjusting the set angle between CAD 208 enclosures - compression mode and fixed mode. In compression mode, the angle is easily adjusted after the flown array is up and in place. This requires a lashing-strap or chain hoist. In fixed mode, the angle is determined during setup and the flown array cannot be adjusted later. This option does not require a lashing-strap or chain hoist.

4.1 Compression Mode

Determine the set angle between two enclosures simply by adjusting the lower Set Angle pin; the top pin always glides in the slot on the Link connector. This way one person can easily curve the array.

The following angles may be adjusted between two CAD 208 enclosures: 0^ , 1.5^ , 3^ , 4.5^ , 6^ , 7.5^ , 9^ , 10.5^ , 12^ , 13.5^ , and 15^ .

Fig. 12: The CAD 208's set angle in compression mode is 4.5°

The rigging hardware is designed so that you can adjust the set angle on a flown CADISTM array; that is, after it has been hoisted.

How does this work?

The pin that determines the set angle is merely a predefined stop for the flexible connector component when the entire CADISTM array is compressed accordion-style at the back and adjusted using a lashing strap or chain hoist. When no force is exerted, the entire mid/high array is suspended at 0°, meaning that the Set Angle pin is easily repositioned. kann verstellt werden.

Important note: The pin labeled Link connects individual CAD 208 cabinets. Ensure this pin is inserted; otherwise the enclosures will not be connected to each other and may swing forward!

4.1.1 Preparations

The following section describes how to set up an array in compression mode. Use CADIST™ CAPS software to select rigging frame pick points for setting the angles between CADIST™ 208 mid/high enclosures.

4.1.2 Mounting the Rigging Frame

It takes two people to perform these tasks. Remove the quick-release pins from the rigging frame and the two pins on the back of the top CAD 208 enclosure. Place the rigging frame on the enclosure. First attach the two front connectors. Turn the rigging frame's connector component down and slide it into the rear rigging connector.

You may mount the top mid/high enclosure to the rigging frame in fixed or in compression mode. To attach it in compression mode, insert the first pin through the hole labeled Link on the enclosure and attach the connector component by inserting the second pin through the slot into the hole labeled 7.5°. To attach it in fixed mode, insert the first pin through the hole labeled 4.5° on the enclosure and attach the connector component by inserting the second pin through the slot into the hole labeled 7.5°.

Note: The maximum set angle for the top mid/high enclosure is 7.5^ (with the rigging frame set to 0^ ).

Fig. 13: Rigging frame set to o°

Attach to the top rigging frame the shackle that will hold the motor's hook. Your choice of pick point depends on how sharply you aim to curve the entire array later.

Note: Depending on application, you may not be able to select a pick point with a shackle. In this case, use two shackles and a suitable O ring as shown in Figure 14.

Check all pins on the top rigging frame to ensure they are firmly seated and attach the motor to the shackle.

Important: Ensure the motor's chain bag hangs freely and does not rest on the rigging frame!

Fig. 15: Mounting the standard rigging frame

Engage the motor to lift the cabinet from the case. Roll the case off to the side. Remove the two front pins from the lowest enclosure and fold down its connector component. Now you can rig the second two-cabinet block.

Curve the four CAD 208 enclosures as desired for the given application by setting the pins on the back accordingly. Determine the desired angle using the pin labeled "Set Angle".

Fig. 16: Setting the angle to curve a CAD 208 array

Connect the speaker cords to the four enclosures that will later be at the top of the array. Bear in mind that you must attach one of the shackles on the rigging frame to the lashing strap or chain hoist that will later serve to pull back the ends of the array and curve out its front face. Do this now.

Tip: If you intend to rig more CAD 208 enclosures, we recommend that you attach all the required speaker cords to the top rigging frame now because this task gets more difficult as the array grows. Be sure to use cords of sufficient length!

4.1.3 Rigging Additional CAD 208 Enclosures

Hoist the mounted mid/high enclosures to a height that allows you to roll additional CAD 208 cabs under the array. Remove the two front pins from the lowest flown enclosure.

Fig. 17: Hoisting the top four CAD 208 enclosures

Move the additional CAD 208 enclosures into position. Slowly lower the top four cabinets until the two front connectors engage. Insert the two front pins first, ensuring that they engage fully and securely. You may have to shift the two enclosures slightly to ease the pins into position. In order to attach the rear connector component, you must swivel it out of the rail so that it faces down. To connect the two blocks, insert the pin through the connector's slot and through the hole labeled "Link".

Hoist the CADISTM array with the eight enclosures high enough so you can add further cabs to the bottom of the array.

Insert the pins on the back of the bottom four enclosures' "Set Angle" holes to achieve the desired curvature. Connect the remaining speaker cords.

Repeat the above procedure if you wish to add more CAD 208 enclosures to the flown stacked array.

4.1.4 Hoisting the System

The enclosures are rigged, speaker cords are all connected, and the pins are set in the required configuration.

If you have opted for compression mode and want to use the lashing strap to curve the CADIST™ array, connect one of its hooks to the rigging frame. Using a shackle (with an 8-mm bolt), attach the hook on the other end to the bottom cab, with the best choice of anchor being the connector component.

Tighten the strap until it exerts enough force to curve the array as desired.

Fig. 19: Attaching the lashing strap

Once you have hoisted the CADISTM array, secure it against gusts of wind or unintended twisting using two lashing straps or ropes.

4.2 Fixed Mode

To determine the set angle between two enclosures in fixed mode, you must insert one pin (Set Angle) and secure the connector in place with the second pin. To set the selected angle, insert the pin into the neighboring hole labeled "Link" above the selected angle (Set Angle). This fixes the connector component in place so that it is immobile in all directions.

This gives you the same set angles between two CAD 208 enclosures to choose from as in compression mode; that is, 0^ to 15^ in 1.5^ steps.

Fig. 20: Example of a fixed mode application with a 4.5° angle

Follow the same procedure as for compression mode to set up the system in fixed mode. Often when arrays are sharply curved it becomes difficult to rig additional blocks. In this event, you must mount enclosures individually from below.

5 Flying CAD 115 Subwoofers

5.1 Components

You'll need the following components to fly CAD 115 subwoofers:

• a standard rigging frame
  • the pick points on the side panels of CAD 115 subwoofers
• CAD 115 subwoofer rigging kit consisting of four connector components and eight pins
• rigging yokes for mounting CAD 208 enclosures to CAD 115 subwoofers (2 parts + 6 pins)

5.2 As an Independent Bass Array on a Second RiggingFrame

The standard rigging frame is certified to fly up to ten CAD 115 subwoofers in stacked array. Be sure to also read and heed the safety regulations in chapter C of the manual.

Rigging

Set the standard rigging frame on the CAD 115 subwoofer with the rubber feet facing down. Remove the four pins on the rigging frame. Attach the four (optional) connector components between the rigging frame and the CAD 115 enclosure using the pins. Attach the shackles for the motor to the rigging frame. Attach the motor to the shackle and lift the subwoofer. Now you can rig additional CAD 115 bins below this subwoofer. You need four connector components and eight pins for each subwoofer to do this.

5.3 In Combination with CAD 208 Mid/High Enclosures

Configuring subwoofers and mid/high enclosures together in a single array may be practical, depending on application. Subwoofers must be rigged on top of the flown array for this application.

Mind the rigging frame's maximum permissible load. Before you begin, add up the individual components' weights to determine the total system weight. Refer to tables 1 and 2 in chapter C, Rigging the CADIST™ System, for weight specifications.

Use the connector to attach the top CAD 115 Sub to the rigging frame. To add mid-/high-range enclosures to the array, mount the optional rigging yoke to the bottom subwoofer by inserting four pins into the enclosure's recessed rigging rails.

You may mount the first mid/high enclosure to the rigging yoke in fixed or in compression mode. For a o° set angle, insert the first pin through the slot labeled Link on the enclosure and attach the connector component by inserting the second pin in the hole labeled o° Ground-stacking.

This configuration is recommended for smaller venues, for example, in which enclosures cannot be flown, or when you want to aim the array to cover galleries, terraces or balconies.

5.4 With a Standard Rigging Frame

Set the standard rigging frame, without shackles and with the rubber feet facing down, on the ground, on bass bins (attaching the frame to the bin) or on the stage so that the connector components for the CAD 208 enclosures face up.

Fig. 23: Ground stack with the standard rigging frame

Remove all pins from the rigging frame and mount the CAD 208 enclosures upside down, one after another. The procedure is the same as for a flown system in fixed mode, except that enclosures are stacked upside down. This lets you tilt the stack downwards by up to 7.5°. To do this, use the set angles in fixed mode. The table below shows which angle between the rigging frame and the first mid/high enclosure gives you the desired down-tilt:

Desired down-tilt Label on the CAD 208
0^ (horizontal) 7.5^
1.5^ 6^
3^ 4.5^
4.5^ 3^
6^ 1.5^
7.5^ 0^

Table 3: Set angle between the rigging frame and the first mid/high enclosure

Caution: Always secure ground stacks with a suitable lashing strap to prevent slippage!

5.5 With CAD 115 Subwoofers

Stacked black industrial equipment units on a white background (no text or symbols visible)

Fig. 24: Ground stack with CAD 115 subwoofers

Operating the System

We recommend that you follow the procedure described to help prevent errors and quickly troubleshoot problems. The adverse effect of a mid/high cabinet dropping out or an incorrect connection can seriously degrade any system's performance, especially that of a line array!

5.6 Connecting Speaker Cords

Always lay out cables clearly and orderly. You should be able to readily identify which enclosure connects to which power amp channel at any time. This ensures flaws such as defective cords can be pinpointed and redressed quickly.

5.7 Checking Individual Mid/High Enclosures

The best method of checking cabinets is to play a familiar track on a CD (for example, the latest HK Audio demo CD), routing the signal into the mixer and out via the master channel. Set the master level to a low to medium setting.

Turn up the given channel's gain knob. You will hear the signal rendered by the two connected mid/high cabinets and the assigned controller should indicate the incoming signal level.

Important note: If you are located outside the high frequency signal's directivity coverage, you will not be able to hear this signal! This system check is best performed with a helper positioned a suitable distance from the array. If you see the bottom of the mid/high unit as a flat surface, you are definitely outside its directivity coverage.

Turn the power amp channel's gain knob back down after hearing the signal. Follow the same procedure for all other power amp channels that you wish to use. Be sure to turn the gain knob down after each successful test.

Note: This procedure checks mid/high cabinets in descending order; that is, from top to bottom. A cabinet's height affects its directivity, so the lower the enclosures, the closer the listener should move in towards the array.

Follow the same procedure to check subwoofers.

Once you have checked all cabinets successfully, turn up all gain knobs, one after the other.

Start with the channel 1 gain knob for the top mid/high units, and then turn up the channel 2 gain knob, and so forth. With every additional channel that you activate, you should hear a boost in low midrange response. If not, this may be due to a phase inversion in the NF (or in extreme cases, in the speaker cords). Proceed in the same manner for the subwoofer channels.

5.8 Configuring the Controller Network Using Audio Controller Software

Once you have performed these tests, you can configure the controller network. The type and size of the configuration of course depends on the given sound reinforcement task (PA left/right, center, out-fills, etc.).

Read the chapter on controller software in the manual to learn more about networking controllers, creating groups, and setting delays and levels.

6 Tearing Down and Transporting the System

To tear down the system, start where you left off and work your way backward; that is, proceed in the reverse order of assembly.

These tips should make the job of tearing down the mid/high array easier if you use cases for your CADISTM system:

Lower the array until the bottom of the case for mid/high units fits under it.

Engage the motor or chain hoist to relax the tension on the strap that is curving the array. Caution: The array may swing out towards the front! Disconnect at least the four lower cabinets' cords.

Set the Set Angle pins that are determining the array's curving to 0^ ! This ensures the array will not buckle when lowering and setting it on the bottom of the case. This also makes it easier to dismantle the four-cabinet block.

Always insert the front pins into the holes on the rigging connector to ensure they are not damaged or torn off when the array is lowered into the case! Carefully lower the array into the case. First remove the rear Link pin connecting the two mid/high units. Then remove the two front pins. Raise the array slightly so that the lower four-cabinet block can be rolled away.

D CADIS™ Aiming Software Setups with EASE Focus

1 Acoustic Simulation of CADIS™ Setups with EASE Focus and the CADIS-GLL for EASE

An acoustic simulation serves to predict expected audio results. Its ability to predict how well a proposed sound reinforcement solution will work in practice makes it very helpful in mastering sound reinforcement challenges. Best of all, it lets you perfect the sound system before you actually set it up. The simulation helps detect errors beforehand, sparing you the considerable extra effort it takes to correct flaws after the system is up. For this reason, acoustic simulations have become standard practice for fixed installations and a handy tool used in many projects.

With the arrival of line arrays, acoustic simulations are seeing more frequent use for mobile sound reinforcement. And for good reason, because achieving a satisfying audio result with a line array requires very careful configuration and alignment. To help you determine such a best-case configuration and alignment of the CADIST™ Line Array before you set up or install it, HK AUDIO offers a system definition file (CADIS.EFO) for the simulation program EASE Focus and a generic speaker library file (CADIS.GLL) for EASE version 4.2 and higher.

EASE 4.2 takes into account the given acoustical conditions to calculate all relevant audio parameters such as direct and overall sound levels, delay times, clarity, speech intelligibility, and so forth, as well as to create auralizations. EASE 4.2 is used above all to plan CADISTM system configurations for fixed installations and larger mobile sound reinforcement projects.

In contrast, EASE Focus is employed for mobile sound reinforcement applications that allow little time for complex simulations. It calculates a CADIST™ configuration's sound dispersion across audience areas in a vertical sectional view, whereby the room's acoustical influences are not taken into account. EASE Focus lets you determine the best configuration and alignment for a sound rein-

forcement application in a virtual simulation; that is, without having to map the room's complexities and without setting up, testing, and adjusting the system until you find the optimum solution.

Note: Bear in mind that precisely measuring a room's dimensions and geometry (particularly of the audience areas) and carefully planning the CADISTM configuration will always take less time than determining the best possible configuration by trial and error. Oftentimes, CAD files - or at least scale diagrams of halls – are available on venues' websites. These sources can provide all the information required for prior simulation.

The following applies to every simulation:

Calculated SPL values can only be reproduced precisely using the appropriate test signals. In (live) music applications, differences may occur as a result of different spectra and crest factors.

To learn more about how to simulate sound reinforcement scenarios and handle EASE Focus and EASE 4.2 simulation programs, functions, and parameters, see the given program's manual or online help (http://www.easefocus.de/downloads.html). You'll find a description of functions and options of the generic loudspeaker library file (CADIS.GLL) embedded in EASE 4.2. Open this description by clicking the Embedded Files button in CADIS.GLL. To access it in the EASE GLL Viewer, open CADIS.GLL, go to the File menu, and select the option Embedded Data Files.

E Controlling CADIS ^TM

You have two options for controlling a CADISTM system:

• In two-way active mode, the FIRNET serves as a stereo FIR controller.
• In tri-amped mode, the amps drive the CAD 208 speakers directly, without internal X-overs.

You have a choice of two amps for powering the system, and the appropriate filter settings are available for each:

• FIRNET Linear Phase Controller / VX2400 power amp (abbreviated VX in the following)
• FIRNET Linear Phase Controller / LAB.gruppen FP 10000Q (abbreviated FP in the following)

Note: When operating your system, always ensure components are connected properly and the correct gain settings are dialed in at the controller and on the power amps. For more on this, see section F, Controllers and Controller Software.

F Controllers and Controller Software

1 FirNet™ Controller

Note: This quick guide provides fast orientation if you have experience using devices similar in design. A detailed user manual is available for downloading at www.hkaudio.com.

Getting started

1. Fundamentals

The controller requires different settings for systems driven by different power amps, so you must adjust the Max Output Level in the Admin menu according to which amps you're using, HK AUDIO VX 2400 or Lab.Gruppen FP10000Q. What's more, different system configurations need different speaker filters. The controller ships without speaker filters, so you'll have to load the entire filter library or the individual filter that you need. You'll find the filters alongside LI-PAN software and other important info on the included CD-Rom.

Here's what you must do before you run the FIRNET controller for the first time:

1. Us a network cable to connect the network ports of your PC and the FIRNET controller.
2. Store the files on the CD-Rom in a new folder on your PC.
3. Install LIPAN software so you can load filters and edit the FIRNET on your PC.
4. Load speaker filters. You'll also find filter banks and individual filters serving to operate the FIRNET with Lab.Gruppen FP10000Q and HK AUDIO VX 2400 power amps on the included CD-Rom.
5. Check the analog gain structures in the FIRNET controller's Admin menu items "Max Input Level" and "Max Output Level". Adjust the settings if necessary – that is, if you're using the FIRNET with Lab.Gruppen amps.

2. PC settings

Entering an IP address to the PC:

The connected PC must have an IP address with the first seven numerals 192.168.1.100 (-254). In other words, ensure the bold numbers appear in the first three address blocks. Feel free to use any number from 100 to 254 in the last address block. However, the PC and connected controller may not have the same numerals in the last block.

Viewing the controller's IP address:

Network environment → double-click network link → Scroll down to and right-click TCPIP:

→IP address properties (If you change the IP address, you must restart the PC.) This is where you can view your controller's preset IP address after the FIRNET boots: Navigation wheel → Scroll down one in the menu to view the IP address. You can only change it on the FIRNET controller. Read the detailed explanation in the Quick Guide or FIRNET manual to learn more about this.

Fig. 25: FirNet™ Entering your PC's IP address

3. Installing LIPAN software

Use a Cat 5 cable (RJ 45) to connect your PC's network port to the X port on the rear of the FIRNET. If you want to run several FIRNET controllers simultaneously, connect the first controller's II port to the next controller's X port.

Place the CD-Rom in your disk drive and store all data in a newly created folder. Then select the file named XP_Install HK AUDIO LIPAN Ver 1.2.0.4.zip, or VISTA_Install HK AUDIO LIPAN Ver 1.2.0.4.zip if your PC runs WIN Vista.

Unzip the .zip file on your disk drive into the same folder. Double-click XP_Install HK AUDIO LIPAN Ver 1.2.0.4.exe to start the LIPAN software's installation routine.

FirNet Display

The LCD shows information on presets and parameters. The default readout appears after the device is powered up, and then the display indicates current speaker selection settings and the LAN status. Once you begin navigating adjustable parameters, it shows values pertaining to these parameters.

FirNet Menu Keys

Menu keys (Speaker, Level, Scene, Delay/Phase und Admin) serve to access the various parameter sections. You can adjust the indicated parameters and save these settings using the edit select keys (cursors and back key) for the selected input and output. Pressing the back key always takes you to the next higher menu level.

Note: The device retains stored values even if a power failure occurs or it is unplugged from the mains supply.

FirNet Channel Mute

• Using Channel Mute Shortcuts to Mute Outputs A/B/C/D

You can use combinations of the Admin menu key and the four other menu keys (Speaker, Scene, Level, Delay/Phase) to mute the FIRNET's output channels in A/B/C/D sequence. For example, if you wish to mute output A, press Admin + Speaker; to mute output D, press Admin + Delay/Phase. Press the same combination again to reactivate the output.

Note: Each of the output channels' red signal LEDs show the given output's mute status (constant red = MUTE).

Rear Panel Connectors

14 100-240 V\~ / 50-60 Hz Mains

This three-pole non-heating equipment connector with a ground contact connects the FIRNET controller to the mains power supply. The multi-voltage power supply unit allows the controller to be connected directly to all mains voltages ranging between 100 V and 240 V without requiring transformers and the like. Its maximum power consumption is 40 VA, which corresponds to about 175 mA maximum current consumption at 230 V mains voltage and about 400 mA at 100 V. Do not connect the device using anything other than a three-pole connector with a ground contact. The mains outlet must also be equipped with a ground contact. Never use damaged cords, plugs, or sockets.

15 GPIO

This 25-pin sub-D port provides four each floating inputs and outputs for future firmware versions' use, for example, to remote-control power amps or switch controlled devices. Current firmware does not support this feature.

16 Ethernet PC Control Ports

Ethernet ports relay remote control and monitoring data between a PC and FIRNET controllers via computer networking hardware. The Ethernet X and Ethernet II connectors are RJ-45 ports (Input X = for cross input, II = parallel input).

Cabling:

If you do not wish to use further network hardware such as hubs and switches, connect the PC's network port to the first FIRNET's Ethernet X port using CAT5 network cable. Then also use a CAT5 network cable to connect the first FIRNET's Ethernet II port to the second controller's Ethernet X port, and so forth.

Use a CAT5 network cable to connect the FIRNET controller to hubs or switches, patching the FIRNET controller's Ethernet II port to the hub or switch's network port. To daisy-chain further FIRNET controllers, connect the first FIRNET's Ethernet X port to the second controller's Ethernet II port, and so forth.

Tip: We recommend that you connect all FIRNET controllers to switches. If you do not, and one controller fails in setups comprising several -connected FIRNET controllers, the entire networked chain will drop out.

17 AES/EBU IN Digital Audio Input

Connect signal sources with digital outputs to these three-pin female XLR sockets. Pin assignments are pin 1 = ground, pin 2 = signal, and pin 3 = signal. The FIRNET controller accepts sampling rates of 48 kHz and 96 kHz, which may be selected via a menu option.

Input-Output Signal Routing:

The analog INPUT A – that is, the left channel of the digital AES/EBU signal - delivers the signal to OUTPUT A and OUTPUT B. OUTPUT C and OUTPUT D receive their signal from analog INPUT B, that is, the right channel of the digital AES/EBU signal. You can reroute signals in the LIPAN software's Admin window.

18 AES/EBU OUT Digital Audio Output

The signal patched into the AES/EBU input can be routed through in digital format to other devices via this three-pin male XLR port. Pin assignments are pin 1 = ground, pins 2 and 3 = signal. The FIRNET amplifi es the incoming digital audio signal to preserve signal quality. If a FIRNET controller drops out, the signal is routed directly from the digital AES/EBU IN to the digital AES/EBU OUT via a parallel circuit.

To select the digital input, go to the Admin menu (press ADMIN once), choose the menu option Input Options (press 1x ☑), and then press ENTER to confirm:

Menu option - ADMIN/Input Options/ Input Source

Keylock ↑ Input Options ↓↓

Input Assign: A/B ←↑ Input Source: Analog → ↓

Input Assign: A/B < Input Source: Analog

Synchronization Ports for Analog Audio Signals:

If you wish to address several FIRNET controllers via their analog inputs, you can use digital AES/EBU IN inputs and AES/EBU OUT outputs to synchronize these controllers to ensure the audio signal remains coherent.

To do this, connect the first FIRNET controller's digital AES/EBU OUT to the second FIRNET's digital AES/EBU IN. Then connect the second FIRNET controller's digital AES/EBU OUT to the third FIRNET's digital AES/EBU IN, and so forth.

Fig. 33: FirNet™ - Rear

Leave the first FIRNET's digital AES/EBU IN and the last FIRNET's digital AES/EBU OUT unoccupied. The first FIRNET is the master, providing the clock for the other slaved controllers, so access this FIRNET's menu function to select the internal clock. Configure the other controllers so they accept synchronization commands via the AES/EBU signal and select their analog inputs for the audio signal using the appropriate menu options.

Note: The Sync LED on subsequent controllers in the network light up to confirm they are synchronized.

19 INPUT A, INPUT B Analog Audio Inputs

Connect signal sources with analog outputs to these three-pin female XLR sockets. Pin assignments are pin 1 = ground, pin 2 = signal (+), pin 3 = signal (-). These electronically balanced ports' input impedance is 9 kohms. An electronic filter protects them against HF interference.

A menu option lets you adjust input sensitivity in four steps (6 dBu, 12 dBu, 18 dBu, 24 dBu) to match the FIRNET controller's input to the connected audio device's analog output. Proper matching vastly -improves the signal-to-noise ratio at the FIRNET controller's analog input.

To match levels, go to the Admin menu (press ADMIN once), choose the menu option Analog Levels (press down arrow thrice), and then confirm by pressing ENTER.

Menu option - ADMIN/Analog Levels

The FIRNET uses stacked AD converters to achieve >128 dB (A) input dynamic range.

Note: You must manually set analog levels to 18 dBu after a firmware update.

20 OUTPUT A to OUTPUT D Analog Audio Outputs

Use these three-pin XLR male sockets to route output signals to power amps. Pin assignments are pin 1 = ground, pin 2 = signal (+), and pin 3 = signal (-). These electronically balanced connectors' output impedance is 35 ohms.

The DA converters' output dynamic range is >125 dB (A). A menu option lets you adjust the maximum output level in four steps (6 dBu, 12 dBu, 18 dBu, 24 dBu) to match the levels of the FIRNET controller's output and the connected power amp's analog input.

Adjust the FIRNET's analog output signal's maximum level (Max. Output) to match the downstream power amp.

Heads up: Correct limiter settings ensure the FIRNET operates safely with the various power amplifiers that drive HK AUDIO loudspeakers. To this end, adjust Max. Output Level settings as follows:

Gain (L.A.B. FP10000Q): +26 dBu

Voltage Peak Limiter: 150 V, Soft Mode Max Output (Firnet): +18 dBu

Settings for HK AUDIO VX 2400 amps:

Gain VX 2400: +35 dBu Max Output ( Firnet): +6 dBu

Important note:: The FIRNET's limiter cannot effectively attenuate signals when set to other dBu levels, so connected speakers may be damaged or destroyed.
