General Notes on Safety for Loudspeaker Systems

Mounting systems may only be used for those loudspeaker

systems authorized by the manufacturer and only with the mounting accessories specified by the manufacturer in the installation instructions. Read and heed the manufacturer's installation instructions. The indicated load-bearing capacity cannot be guaranteed and the manufacturer will not be liable for damages in the event of improper installation or the use of unauthorized mounting accessories.

The system's load-bearing capacity cannot be guaranteed and the manufacturer will not be liable for damages in the event that loudspeakers, mounting accessories, and connecting and attaching components are modified in any way.

Components affecting safety may only be repaired by the manufacturer or authorized agents, otherwise the operating permit will be voided.

Installation may be performed qualified personnel only.

and then only at pick-points with sufficient load-carrying capacity and in compliance with local building regulations. Use only the mounting hardware specified by the manufacturer in the installation instructions (screws, anchors, etc.). Take all the precautions necessary to ensure bolted connections and other threaded locking devices will not loosen.

Fixed and portable installations (in this case, speakers mounting accessories) must be secured by two independent ties to prevent them from falling. Safeties must be able to accessories or parts that are loose or may become loose.

Ensure compliance with the given national regulations when using connecting, attaching, and rigging devices. Factor potential dynamic forces (jerk) into the equation when determining the proper size and load-bearing capacity of safeties.

1 Be sure to observe speaker stands' maximum load-bearing capacity. Note that for reasons of design and construction, most center stands are approved to bear centric loads only; that is, the speakers' mass has to be precisely centered and balanced. Ensure center stands are set up stably and securely. Take appropriate added measures to secure speaker stands, for example when:

• the floor or ground surface does not provide a stable, secure base.

• they are extended to heights that impede stability.

• high wind pressure may be expected.

• there is the risk that they may be knocked over by people.

Special measures may become necessary as precautions against unsafe audience behavior. Do not set up speaker stands in evacuation routes and emergency exits. Ensure corridors are wide enough and put proper barriers and markings in place when setting speaker stands up in passageways. Mounting and dismounting are especially hazardous tasks. Use aids suitable for this purpose. Observe the given national regulations when doing so.

Wear proper protection (in particular, a helmet,

gloves, and safety shoes) and use only suitable means of ascent (ladders, scaffolds, etc.) during installation. Compliance with this requirement is the sole responsibility of the company performing the installation.

WARNING: After installation, inspect the system comprised mounting fixtures and loudspeakers to ensure it is properly d.

The operator of loudspeaker systems (fixed or portable) must regularly inspect or task a third party to regularly inspect all system components in accordance with the given country's regulations and have possible defects repaired immediately.

We also strongly recommend maintaining a logbook or the like to document all inspections.

When installing speakers for longer lasting or permanent outdoor operation, be sure to take into account the stability and load-bearing capacity of platforms and surfaces; loads and forces exerted by wind, snow, and ice; as well as thermal influences. Also be sure to provide sufficient safety margins for the rigging points used for flow systems. Observe the given national regulations when doing so.

• Ask the manufacturer if your product is allowed for outdoor usage!

Professional loudspeaker systems can produce harmful noise levels. Even prolonged exposure to seemingly harmless levels (e.g. at about 95 dB SPL) can cause permanent hearing damage. We therefore recommend that everyone who is exposed to high noise levels produced by loudspeaker systems wears professional hearing protection (earplugs or earmuffs).

1 General Information

Unpacking and Inventorying

When you first unpack your LUCAS 2K15 or LUCAS 2K18, take a quick inventory to make sure the package comes complete with all the contents. LUCAS 2K consists of a subwoofer and two satellites. A mains cable is also included.

The System's Components

LUCAS 2K18LUCAS

The Subwoofer

The LUCAS 2K15 subwoofer is loaded with a 15" woofer; the LUCAS 2K18 with an 18" woofer. Each houses the system's active circuitry and the Class D power amplifiers. The connection and control panel is on the rear.

The Satellites

The two each LUCAS 2K15 and LUCAS 2K18 satellites are equipped with an 8^ midrange woofer and a 1^ compression driver with a 90^ × 55^ CD horn. A Speakon NL2 input is on the rear. The 3^ MonoTilt pole mount on the bottom serves to place the satellites on a speaker stand.

Heads up! The system's components are matched for the best possible audio performance and may only be operated in the specified configuration. The use of satellites other than these will not only degrade the sound; it may also damage the power amp as well as connected outboard devices.

2 Connectors and Controls

Input

Plug a cord equipped with an XLR connector or 1 / 4^ / 6.35 mm jack plug into this electronically balanced XLR/ 1 / 4^ / 6.35 mm combo input to send a L/R stereo line signal from your DJ controller, mixing console, keyboard or the like to the system.

2 Thru

These balanced parallel XLR outputs serve to send the L/R stereo signal routed into Input (1) through to other components such as powered monitors. The Thru jacks also connect the optional HK Audio LINEAR SUB series model L SUB 1500 or L SUB 1800 A subwoofer. These bass bins come highly recommended if you wish to boost your system's low-end performance.

Heads up! The two recommended subwoofer add-ons and the respective systems are matched to guarantee the best audio performance. We cannot guarantee that other components will interact properly with your system.

3 Power LED

This LED lights up green when the Power button (10) is set to On and the unit is getting mains power.

4 Master

The Master knob adjusts the gain and thus the volume for the entire LUCAS 2K system. Turn it all the way down—that is, as far left as it will go—before switching on the system.

Sub

The Sub knob adjusts the subwoofer's volume separately. The satellite and subwoofer's volume levels are relatively balanced when the knob is set to the 0 dB—that is, the center-notched 12 o'clock position.

Limit Sat

This LED tells you the limiter is operating in the satellites' frequency range. Heads up! If the Sat LED stays red while the system is up and running, it is being overloaded. Turn down the Master knob! If you are not feeding a signal into the system and the LED stays red, there has been malfunction. Contact our Technical Service.

7 Limit Sub

This LED tells you the limiter is operating in the subwoofer's low frequency range.

Heads up! If the Sub LED stays red while the system is up and running, it is being overloaded. Turn down the Master knob! If you are not feeding a signal into the system and the LED stays red, there has been malfunction. Contact our Technical Service.

Flat/Bass Boost Selector

This DSP-driven EQ optimizes the frequency response for the given application.

Flat: This is the default. When this switch is set to Flat, LUCAS 2K delivers a factory-tuned, balanced audio image.

Bass Boost: If you want LUCAS 2K to pack a more powerful low-end punch, set the switch to Bass Boost to bring up the subwoofer's low frequencies.

This switch also serves to adapt the LUCAS 2K's frequency response when you've added an optional LINEAR SUB series subwoofer to your setup. For more on this, see section 5, "L SUB 1500 or L SUB 1800 Bass Extensions" and the configuration examples shown in the appendix starting on page 32.

9 Auto Sleep

LUCAS 2K's Auto Sleep mode is enabled when the button is set to On. If the system is left to idle for 350 minutes without receiving a signal, the amp switches to this power-saving mode where it consumes around 0.5 watts. To wake it up, first press the power button to switch the system off for five seconds. Then switch it on again to bring LUCAS 2K back on line. Set Auto Standby to the Off position if you wish to disable this function and ensure LUCAS 2K remains up and running.

10 Power

This is LUCAS 2K's on/off button. The power LED lights up green when it is engaged.

11 Satellites Out

Plug speaker cords no less than 1.5mm^2 thick and equipped with Speakon NL2-compatible +1/-1 connectors into these speaker outputs to connect the LUCAS 2K satellites. If you connect any other device, it and the LUCAS 2K subwoofer may be irreparably damaged.

Note: Be sure to rotate speaker connectors clockwise until they lock in place!

Heads up: This type of connector has to be turned clockwise until it engages. It also has to be disengaged before it can be unplugged. To this end, pull the bayonet catch towards the cord and turn the connector counter-clockwise.

12 Mains

Use the factory-included mains cord to connect this socket to a wall outlet. Note: LUCAS 2K is equipped with a V-Lock mains socket. If you use a Volex locking power cord or another optionally available brand with the same design, you can fix the power cord in place to prevent accidental disconnection.

Caution! Make sure the local mains voltage matches the voltage specified on the LUCAS 2K subwoofer. Connecting it to the wrong mains voltage may destroy its electronic components.

Satellite Input

Plug speaker cords no less than 1.5mm^2 thick and equipped with Speakon NL2-compatible +1/-1 connectors into these speaker outputs to connect the satellites to the subwoofer's Satellites Out (11) ports.

3 Powering Up

• Make sure the mains cord is connected and the Power button 10) is set to Off.
• Turn the Master (4) knob all the way down to the far left.
• Connect the two satellites to the subwoofer.
• Switch on all components connected to LUCAS 2K.
• Then push the Power button (10) to switch on the system.

Heads up: Always switch LUCAS 2K on last-that is, after powering up all other components-and switch it off first before powering down all other connected devices.

4 Setting Up

4.1 Placement

The subwoofer needs to be centered between the two satellites for the system to deliver a balanced stereo image.

4.2 Vertical Alignment

The MonoTilt™ pole mount's 3^ angle ensures the satellites remain at their center of gravity. This slight tilt also serves to better align the speakers to the audience.

The MonoTilt pole mount's diameter is 36 mm so LUCAS 2K satellites can be mounted on any standard speaker stand.

Heads up! Always place speaker stands on a stable, sturdy surface and never exceed the manufacturer's load-bearing specifications.

Caution:

• Use only speaker stands that are stable enough to prevent accidental tipping after satellites are mounted. Ensure the speaker stand is designed to handle the satellite's weight. Adjustable stands' highest setting must be limited so as to prevent the combination of speaker stand and satellite from tipping. This applies when setting the stand on a fl at, horizontal surface.
• When setting up on an uneven or sloping surface, make sure the speaker stand's base is secured to prevent accidental tipping, either by attaching suitable weights to the base or taking other safety measures.
• The use of any other fixtures or fittings can result in instability that may cause injury.

4.3 Horizontal Alignment

The satellites' horizontal directivity is around 90^ . Depending on the venue and room layout, you may want to turn the satellites inwards towards the audience area.

5 L SUB 1500 or L SUB 1800 Bass Extensions

You can also extend the LUCAS 2K system with an add-on subwoofer, either an L SUB 1500 A for LUCAS 2K15 or an L SUB 1800 A for LUCAS 2K18.

To do this, use two XLR-equipped cords to connect the LUCAS 2K subwoofer's L/R Thru ports (2) to the L SUB subwoofer's L/R Inputs.
- Set the LUCAS 2K subwoofer's Flat/Bass Boost selector (8) to Bass Boost and the Sub knob (5) to the 0 dB center-notched position. Set the connected L SUB unit's Sub-Gain to -6 dB, its X-Over to 100 Hz, and the Phase switch to 0^ .

Heads up: For more on this, see the configuration examples shown in the appendix starting on page 32.

Place the two subwoofoers next to each other, preferably centered between the two satellites, for the system to deliver a balanced audio image.

6 Optional HK Audio Accessories

1. SPEAKER STAND ADD-ON

This package contains two height-adjustable aluminum tripod speaker stands (112 to 190 cm), two speaker cords, and one bag.

This package contains a three-piece set of dark grey soft cases, one with an integrated trolley board for the subwoofer and two for the satellite.

3.100 mm SWIVEL CASTERS blue

The optional swivel castors are mounted to the rear of the LUCAS 2K subwoofer using the self-locking screws at the corners.

Heads up! The subwoofer does fit in the LUCAS 2K Roller Bag with mounted swivel casters. However, it does fit in the padded cover for the L SUB 1500 A or L SUB 1800 A add-on subwoofer.
