What is included in your Q-Sys™ product carton:

Q-Sys Core 250i or Core 500i

• Rubber feet
  • Q-Sys Hardware User Manual
  • Q-Sys Designer software CD
  • IEC power cord and cord lock wire
• Connector plug kit appropriate for the optional Q-Sys Audio I/O Card(s) ordered

Mounting

Q-Sys products can be used in or out of an equipment rack. Rack mounting is optional. Adhesive rubber feet are included for non-rack mount installations (table or shelf top installations). Use the feet to prevent the unit from scratching or marring the support surface.

Rack Mount Instructions

Rack mount the Q-Sys product by supporting it from underneath while aligning the front panel mounting holes (in the rack ears) with the threaded screw holes in the rack rails. Install all four mounting screws and washers and tighten securely. All Q-Sys products come with rear rack support ears. Ensure that these rear mounting points are securely fastened to rear rack rails or side walls.

WARNING!: Reliable Earthing – Reliable earthing of rack-mounted equipment should be maintained. Particular attention should be given to supply connections other than direct connections to the branch circuit (e.g. use of power strips).

Mechanical Loading – Mounting the equipment in the rack should be done such that a hazardous condition is not achieved due to uneven or unstable mechanical loading.

CAUTION!: Elevated Operating Ambient - If installed in a closed or multi-unit rack assembly, the ambient operating temperature of the rack environment may be greater than room ambient. Consideration should be given to ensure that the maximum operating temperature listed in "Q-Sys Type 2 System Hardware Specifications" on page 15 is not exceeded.

Reduced Air Flow – Installation of the equipment in a rack should be such that the amount of air flow required for safe operation of the equipment is not compromised.

Circuit Overloading – Consideration should be given to the connection of the equipment to the supply circuit and the effect that overloading of the circuits might have on over-current protection and supply wiring.

Connections

AC Power Cord

Insert the molded receptacle of the AC power cord into the AC power inlet on the back of the Q-Sys product. (Figure 1) Plug the AC line connector into an AC outlet. The power supply on the Q-Sys Cores accepts 100 – 240 V, 50 – 60 Hz. If a different type of IEC power cord is required than that supplied with the product, consult QSC's Technical Services Group.

Q-Sys™ Network

Connect one end of a data communications cable (CAT-6 rating or better) terminated with an RJ45 plug into the LAN A (and optionally LAN B) receptacle on the rear panel of the Q-Sys product. Ensure that the lock tab on the cable engages with the RJ45 receptacle. (Figure 2)

Mic/Line Inputs, Line Outputs, AES3 I/O

Several of the optional audio I/O Cards accept Euro style (also known as Phoenix) three-terminal plugs. (Figure 3) When these cards are ordered in the product configuration a kit containing the mating plugs is included in the carton contents. Plug the Euro terminal block plug into the appropriate input or output receptacle on the Q-Sys Audio I/O Card's panel face. The connection pinout is printed on the Q-Sys Audio I/O Card mounting bracket. Refer to the illustrations in the right-hand column of this page for balanced and unbalanced connections (analog connections only – AES3 connections always require all three conductors).

DataPorts

The Q-Sys DataPort I/O Card is intended to interface with QSC amplifiers with v1 DataPorts. This is the all-capable version 1 DataPort specification, supported on CX, DCA, PowerLight™, PL2, and PL3 Series amplifiers. All DataPorts use the HD15 connector format and connect to QSC amplifiers via data communications cables having male HD15 connectors. (Figure 4)

IMPORTANT: These appear to be common VGA cables but they are not. Many off-the-shelf VGA cables MIGHT work with satisfactory results, however it is also quite possible off-the-shelf cables will give less-than-satisfactory results, and could even cause damage to QSC amplifiers! The QSC DataPort specification requires that all conductors be present, as well as shielding over those conductor pairs used for the audio channels to the amplifier. Therefore, QSC recommends the use of QSC DataPort cables exclusively, which are available in a variety of lengths from QSC. Use of any non-QSC DataPort cable may void the warranty.

To connect a DataPort cable between a Q-Sys DataPort I/O Card and an amplifier DataPort, attach the cable's male connectors to the HD15 ports and fi nger tighten the thumb screws on the connector.(Figure 4)

CobraNet

The Q-Sys CobraNet I/O Card is intended to provide an interface between Q-Sys and QSC's Basis, DCP, and third-party CobraNet devices. The connector required is an RJ45. (Figure 5)

Quick Start Guide

This Quick Start Guide is intended to give a high-level procedure for getting a simple Q-Sys system connected, running a Q-Sys design, and passing audio. The following procedure assumes that you have a Q-Sys Designer file with components properly connected, but not necessarily configured.

1. Set up the Q-LAN network. For more information about Network Requirements see Help File Networking Topic; for a list of qualified switches see "Qualified Ethernet Switches" on page 13, or the QSC website (qscaudio.com).
2. Connect PC, and Core to the Q-LAN network. If you have any I/O Frames, they should be connected to the Q-LAN network at this time.
3. Connect DataPort amplifiers and loudspeakers.
4. Power up the equipment.
5. On the PC, Start Q-Sys Designer.

a. Open your design fi le.
b. Select the Core in the Inventory list, and verify the configuration. Make sure the Core model is correct, and the correct I/O cards are identified in the same slots as they appear in the physical hardware.
c. Open Q-Sys Configurator and select the Core with the same name as in the design. If the names are different, you must change the hardware name or the name of the Core component in Q-Sys Designer so they match. A new Core is shipped with both LANs enabled, and the addressing Mode set to Auto. The available modes are:

» Auto — If there is a DHCP server on the network, the IP Address is automatically assigned. When a DHCP server is not found or non-functional, and the Q-Sys end node is configured for "auto", it will use Link-Local addressing to self assign an IP address in the 169.254.0.0/16 range.

»Static — You assign a static IP Address, Mask and Default Gateway.

» Off – Available on LAN B only. In the Off mode, there is no network redundancy.

d. If you have any I/O Frames, select them one at a time in the Inventory list, and verify the configuration of each.

e. In Q-Sys Configurator, Select the I/O Frame with the same name as in the design. If the names are different, you must change the hardware name or the name of the I/O Frame component in Q-Sys Designer so they match. A new I/O Frame is shipped with both LANs enabled, and the addressing Mode set to Auto. The available modes are:

» Auto — If there is a DHCP server on the network, the IP Address is automatically assigned. When a DHCP server is not found or non-functional, and the Q-Sys end node is configured for "auto", it will use Link-Local addressing to self assign an IP address in the 169.254.0.0/16 range.

»Static — You assign a static IP Address, Mask and Default Gateway.

»Off — LAN B only, no network redundancy

f. Ensure that the amplifiers are properly connected in the design and configured correctly. The connections and configuration should match the physical connections.

g. Ensure that the loudspeakers are properly connected to the amplifiers in the design, and configured correctly. The connections and configuration should match the physical connections.

h. There are many ways to pass audio through the Q-Sys system, your design should contain one or more ways to do this. If not, refer to the Online Help and add one of the components that would allow you to pass audio.

i. Save the design to the Core and connect (Press F5).

j. If the Core's firmware does not match the firmware embedded in Q-Sys Designer on your PC, you are prompted to update the firmware. The Core 250i and 500i are supported by Q-Sys Designer 3.0 and above. Do not install a version of Q-Sys Designer earlier than 3.0.

NOTE: To download the latest Q-Sys Designer software and firmware, go to http://www.qscaudio.com/products/software/QSys.

1. Test the system.

Before trying to pass audio, place the System Mute component in your design, Run the design (F5), and click the Mute button. When you attempt to pass audio for the first time, you can un-mute the system and the output will ramp up to the level of the settings in your design. If the system begins to get too loud, you can press the mute button again and make necessary adjustments.

Overview

Q-Sys™ is an integrated system audio solution. The DSP is centralized to allow faster development and deployment of new features, and requires fewer hardware changes as well. Q-Sys has been designed around four major criteria: Sonic Quality, Reliability, Power and Flexibility.

Type 2 Hardware

Q-Sys has two types of hardware currently deployed. In the Type 2 hardware, new IDC (ribbon type) connectors replaced the FCC (flex type) connectors installed in earlier releases of hardware. Due to this change, the Type 2 hardware is not physically compatible with the older hardware. You can still integrate the new I/O Frames and Cores in the same system with older hardware, but the I/O cards are not interchangeable. Type 2 hardware can be identified by a yellow label (Figure 6) on the back of the Core and I/O Frame, and the bottom of the I/O cards.

- Figure 6 -

Components

Q-Sys is comprised of the following dedicated components:

• Q-Sys Core (Required) – The Core is the central processing unit of Q-Sys. The Core processes and routes all audio, controls peripheral devices, manages firmware updates to the peripheral devices. The Core 250i and 500i have eight slots available to add the I/O cards listed under Q-Sys I/O Cards below. Because the Cores 250i and 500i can have up to eight I/O cards, it can operate as a stand-alone system. However, you can connect one or more Q-Sys I/O Frames to the Q-LAN network to increase the number of I/O cards available to the Core. Refer to the Hardware User Manual for the Cores 1000, 3000, 4000, and I/O Frame (TD 000284) for information.

• Q-Sys I/O Card(s) (One or more required) – The I/O cards, installed in the Core, are the links between the input/output devices and the Core. The I/O cards receive audio from external equipment and send it to the Core for processing. They also receive audio from the Core and send it to output devices. The Core houses one or more of the following: (The Core does not necessarily require any I/O cards, you can have an I/O Frame connected to Q-LAN with I/O cards that would fill the requirements.)

• AES Card – provides the interface between digital devices such as mixing consoles, recording devices, other devices and Q-Sys.

• Blank Card Fills card slot when no card is needed.
  CobraNet Card – provides the interface between QSC Basis, DCP, or third-party CobraNet devices.
• DataPort Card – provides audio, telemetry, and control interface between Q-Sys and QSC DataPort amplifiers and QSC loudspeakers.
  • Line Out Card – provides the interface between third-party amplifiers, recording devices, other devices and Q-Sys.
• Standard (Std) or High Performance (HP) Mic/Line Input Card – provides the interface between input devices (microphones, CD/DVD players, mixers, and so on) and Q-Sys.

- Q-Sys Designer Software 3.0 or Greater (Required for designing, not required for operation) – Q-Sys Designer is the design software application that creates the design file that is loaded onto a Q-Sys Core. The design file contains all the virtual components, their connections and initial DSP settings. The design is initially created on a PC running Q-Sys Designer. When the design is complete, it is loaded on the Core and tested, and adjustments made. When all adjustments are finalized, the design is saved to the Core. Q-Sys Designer is not required to operate the Q-Sys system. Q-Sys Designer requires a Windows-based PC running Windows XP, Windows Vista, or Windows 7.

- Gigabit Ethernet Network (Required only if an I/O Frame, I/O-22, or a Page Station is part of your system.) – The Q-Sys solution is designed around a high performance network implementation called Q-LAN that offers gigabit data rates, device and network redundancy, 32-bit floating point audio data transfers, end node discovery and low-latency support on local area network deployments. Additionally, Q-LAN offers long-haul IP streaming of audio over wide area network deployments. Accurate synchronization of end nodes and high-quality clock distribution are built-in to the solution using the IEEE-1588 Precision Time Protocol. All devices are connected to a managed 1000 Mbps Ethernet switch with appropriate QoS (Quality of Service) enabled suitable for a high-performance gigabit network. For complete details refer to the Q-Sys online help. For qualified switch recommendations see “Qualifi ed Ethernet Switches” on page 13.

• Q-Sys I/O Frame (Optional) – Provides up to four additional I/O cards for a Q-Sys System.
• Q-Sys DataPort Amplifi er Backup Panel • DAB-801(Optional) – Provides N+1 Amplifi er redundancy
• Q-Sys I/O-22 (Optional) – Provides microphone and line level inputs, line level outputs, and amplification services for a Q-Sys audio system.
• Q-Sys Touch Screen Controllers (Optional) – Provides End-User touch-screen, wall-mounted control
  • Q-Sys Page Stations (Optional) – Q-Sys Page Stations are a networked page station solution that connects to a Q-Sys system via Q-LAN.

Q-Sys is an integrated system designed to work with QSC DataPort amplifiers and QSC loudspeakers and other QSC products to provide system-level telemetry and control. Q-Sys can also be configured with generic amplifiers and/or generic loudspeakers, but there is a loss of functionality when not using QSC compatible hardware.

QSC DataPort Amplifiers

QSC DataPort amplifiers (PowerLight™, CX, PL2, DCA, and PL3) can be used in a Q-Sys system to communicate with the Q-Sys DataPort card and provide critical telemetry information and protection for both the amplifier and any loudspeaker. With QSC loudspeaker connected to a DataPort amplifier and Q-Sys, you get additional information and benefits not available with generic loudspeakers. Generic amplifiers can be used in a Q-Sys system by connecting the amplifier to a Line Out connection; however, there is no telemetry or control of either the amplifier or loudspeakers (even QSC loudspeakers) if Line Out cards are used.

Loudspeakers

Q-Sys, QSC DataPort amplifiers, and QSC loudspeakers work together to form an integrated system that provides specific loudspeaker processing (Intrinsic Correction™), telemetry, and protection for the loudspeaker. You can use generic loudspeakers in a Q-Sys system, however there is no Intrinsic Correction provided.

Redundancy

Q-Sys is capable of several redundant configurations to ensure a high level of overall system reliability.

• 2N Core redundancy – Two Cores, primary and redundant, communicating with each other and peripherals to verify system health, and to synchronize control settings.
• 2N Network redundancy – Two separate networks - In this configuration, you can have each Q-Sys Core and/or I/O Frame connected to both networks.
  • 2N I/O redundancy For each I/O Frame, you can have a backup I/O Frame.
• N+1 Amplifi er redundancy— One amplifi er can back up from one to eight amplifi ers with the Q-Sys DAB-801 (DataPort Amplifi er Backup).

Network Redundancy

The Core, I/O Frame, I/O-22, and TSC-8 have two network ports, LAN A (primary), and LAN B (backup). The LAN B port on a unit becomes active when it is configured in Q-Sys Designer as "Is Network Redundant" and connected. Because the every unit is configured in the design file, the Core recognizes it as being on LAN B as well as LAN A. During operation, the Core routes audio and control signals to both ports, so if LAN A, or a part of LAN A fails, the Core switches to LAN B with no failover time.

Q-Sys Hardware Redundancy

The Cores and I/O Frames can have backups connected to the network. Both are identified in Q-Sys Designer as being redundant. The backup Core communicates with the primary to ensure it is up to date with any changes made on the primary, and to monitor the primary Core's health. The Core monitors the I/O Frames, if there is a problem detected with the primary I/O Frame, the Core switches to the backup. The audio inputs and outputs of the primary and backup I/O Frames are wired in parallel, meaning that the audio source drives two inputs. The audio outputs of an offline I/O Frame are disconnected by relays, so only the active I/O Frame, in a redundant pair, drives the outputs.

Q-Sys™ I/O Card Remove and Replace Procedure

This procedure is for Q-Sys Type 2 I/O Cards only. Card installation should only be done by a trained and qualified technician.

Tools

• Phillips screwdriver
• ESD grounded wrist strap
• 1/4" hex driver/socket (not shown) for replacing Q-Sys I/O Cards in positions C through H.

CAUTION!: An ESD grounded wrist strap must be worn throughout the remove and replace procedure. The end of the wrist strap should be connected to an unpainted surface on the product chassis such as the ground stud.

1. Disconnect the AC mains power cord from the Q-Sys Core.
2. Connect and put on the ESD grounded wrist strap.
3. Remove the sheet metal screws securing the lid to the Q-Sys Core chassis. Remove the lid by lifting it approximately 1" at the rear of the chassis while sliding it towards the back.

NOTE: To remove an I/O Card in a position below the top two positions (A and B), you must fi rst remove the appropriate card(s) above it. The following steps apply to both top and bottom cards.

Refer to Figure 10 and Figure 11

1. Locate the I/O Card to be replaced and, except for any Blank Cards, remove the ribbon cable (Figure 11) from the card by gently pushing outward on the cable ejector tabs. The connector should be free of the socket.
2. Remove the two screws securing the I/O Card Mounting Bracket (Figure 12) on the rear of the chassis. Remove the bracket.
3. Remove the I/O Cards: Refer to Figure 13.

a. For cards in positions A or B, remove the four Phillips head screws securing the card to the standoffs. Remove the card. If you are not replacing a card in position C through H, skip to step 7.

NOTE: Figure 13 shows both standoffs and screws for illustration purposes. The screws are only used on cards in positions A and B. All other cards must use the standoffs.

b. For cards in positions C through H, remove the cards in positions A and/or B (step 6.a), then remove the four hex standoffs securing the next lower card, and remove the card. Continue this until you have removed the card you wish to replace.

WARNING!: Domestic and international safety regulations require that this device (Q-Sys Cores) be fully configured before power is applied. All eight audio I/O card bays designated A through H, must include a Q-Sys Audio I/O card, or blank Q-Sys I/O card, and the proper mounting bracket (Figure 12). Failure to properly configure this device will void the warranty.

1. Install the new I/O Card by reversing steps 5 and 6. Be sure to align and secure the I/O Card Mounting Bracket before tightening the hex standoffs or card-securing screws. Complete step 7 and 8 for each single level, or layer, of cards as you replace them. Do not move to the next level of cards until the lower level is properly installed.
2. Reconnect the ribbon cable to the I/O Card, by aligning the tab on the cable connector housing with the key on the card connector as shown in Figure 14. Gently push down on the cable connector housing to seat the cable into the card connector. When properly seated, the cable ejectors will lock in place with the thumb tabs upright.

NOTE: When you connect the ribbon cable to the Core main board be sure that you connect it to the proper connector. The connectors on the Core main board are identified by the slot letters A through H.

1. When replacing the Blank Card with an I/O Card, the new ribbon cable must also be attached to the Core main board. To do this, locate the main board audio connectors. Then locate the appropriate card position indicator (Figure 15) on the main board for the card being replaced (A through H). Attach the ribbon cable in the same manner as the I/O Card, ensuring that the cable connector tab is aligned with the main board connector key and that the cable is properly seated with the ejector tabs in their locked position.

2. Replace the Core lid and secure the lid with the screws removed earlier.

Qualifi ed Ethernet Switches

Q-Sys uses layer 3 (DSCP) QoS. This type of QoS is deployed differently on different networks and therefore requires user intervention to set up properly. Because of this complexity, unmanaged switches are not acceptable for Q-Sys. For more details about network and switch setup, refer to the Help File in Q-Sys Designer. For more details about the following switches, refer to the manufacturers' website. The following switches have been tested and qualify for use with a Q-Sys™ network.

NOTE: Please visit qsc.com for a list of currently qualified switches.

1 The maximum number of local channels a Core can have is 128 in and 128 out (64 in and 64 out). Each card has its own limitations (see the "I/O Cards (Mic/Line In, Line Out)" specifications). You can mix types, directions, and number of I/O channels; the combination dictates the maximum number of channels. For example, if you used all 4 channels of a Line In card, all input and output channels of 2 AES cards, you now have used 12 input channels, and 8 output channels, leaving 116 input channels, and 120 output channels to use with other cards.
2 Requires purchase of I/O cards.
3 Each CobraNet card has up to 32 input channels, and up to 32 output channels. You can reach 256 (128) CobraNet channels with 4 (2) cards or, up to 8 cards.
4 AES3 cards have four input channels, and four output channels per card.
