Frequently Asked Questions - Core 3000 QSC

How do I connect the Core 3000 to my network?

Connect a CAT-6 or better Ethernet cable with RJ45 connectors to the LAN A port (and optionally LAN B for redundancy). Ensure the lock tab engages. Use a managed gigabit switch with QoS enabled.

What software is required to design and configure the Core 3000?

You need Q-Sys Designer software, which runs on Windows (7/Vista/XP with .NET Framework 3.5 SP1). It is used to create design files that are loaded onto the Core. Once deployed, the software is not required for operation.

Can I use the Core 3000 with non-QSC amplifiers and loudspeakers?

Yes, but with limitations. For amplifiers, you can connect via Line Out cards, but you lose telemetry and control. For loudspeakers, you can use generic ones, but Intrinsic Correction and detailed protection features are available only with QSC loudspeakers.

How does network redundancy work with the Core 3000?

The Core 3000 has two network ports: LAN A (primary) and LAN B (backup). In a redundant configuration, the Core routes audio and control signals to both ports. If LAN A fails, the Core switches to LAN B with zero failover time.

What is the maximum ambient temperature for the Core 3000?

The maximum operating ambient temperature is 45°C (113°F). Ensure adequate ventilation in rack installations to avoid exceeding this limit.

How do I install or replace an I/O card in the Core 3000?

Only qualified technicians should perform this. Disconnect AC power, wear an ESD wrist strap, remove the lid, disconnect ribbon cable, unscrew the card bracket, and remove the card. Reverse steps for installation. Refer to the manual for detailed instructions.

What are the GPIO specifications for the Core 3000?

The rear panel has two DA-15 connectors (GPIO A and B). Each provides relay contacts (max 30V, 1A), normal current pins (0-32V input), high current pins (0-32V, can sink/source up to 280mA), and +12V power outputs (max 400mA total per connector).

Does the Core 3000 support redundancy with a backup Core?

Yes, it supports 2N Core redundancy. Two Cores communicate to monitor health and synchronize settings. The backup Core takes over seamlessly if the primary fails.

What type of Ethernet switches are recommended for Q-Sys?

Use managed gigabit switches with Layer 3 (DSCP) QoS. QSC has tested and qualified switches from Cisco (Catalyst 3560E/3750E series), HP ProCurve (3500/5400 series), and Linksys (SLM/SRW series). Unmanaged switches are not acceptable.

How do I update the firmware on the Core 3000?

When you load a design from Q-Sys Designer, if the Core's firmware does not match the software version, you are prompted to update. You can download the latest firmware from the QSC website. The update process is automatic during the design transfer.

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 of the equipment in the rack should be 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 (45°C, 113°F) 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 overcurrent 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. Plug the AC line connector into an AC outlet. The power supply on the Q-Sys Core and I/O frame accepts 100 – 240V, 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 1)

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

Several of the optional Q-Sys Audio I/O Cards accept Euro style (a.k.a. Phoenix) 3-terminal plugs. When these cards are ordered in the product configuration a shop 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 to QSC amplifiers with v1 DataPorts. This is the all-capable version 1 DataPort specification, which is 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 having male HD15 connectors.

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.

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.

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, all via a gigabit Ethernet network. The Core has one slot available to add one of the I/O cards listed under Q-Sys I/O Frame below.
• Q-Sys I/O Frame (Recommended) – The I/O Frame is the link between the input/output devices and the Core. The I/O Frame converts analog input signals to digital and passes them over the network to the Core. It also receives the processed digital audio signal from the Core, converts it to analog and sends it to the output devices. The I/O Frame houses one or more of the following:
• DataPort Card (Optional) – provides the audio, telemetry, and control interface between Q-Sys and QSC DataPort amplifiers and QSC loudspeakers.
• Mic/Line Input Card (Optional) – provides the interface between input devices (microphones, CD/DVD players, mixing consoles, etc.) and Q-Sys.
• Line Out Card (Optional) – provides the interface between third-party amplifiers, recording devices, etc. and Q-Sys.
• AES Card (Optional) – provides the interface between digital devices such as mixing consoles, recording devices, etc. and Q-Sys.
• Blank Card (Optional) – fills card slot when no card is needed.

- Q-Sys Designer Software (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 or Windows Vista.

- Gigabit Ethernet Network (Required) – 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 switch recommendations see Page 12.

• 1 Gigabit Ethernet
• Latency – 0.66 ms across network
• 32-bit floating point format
  • Redundancy (Optional)
  • 1 to 16 channels per audio stream (managed by the Core)
• 1.65 to 3.31 Mb bandwidth per channel (dependent on the number of channels per stream)

- Q-Sys DataPort Amplifier Backup Panel • DAB-801 (Optional) – Provides N+1 Amplifier redundancy

- Q-Sys Touch Screen Controller (Optional) – Provides End-User wall mounted control

• Power over Ethernet
- Touch-Panel Interface
• Design Control Pages in Q-Sys Designer
Core is the server for the saved Control Pages
• Built-in Navigation and SecurityIntegrated System

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 provides critical telemetry information and protection for both the amplifier and any QSC loudspeaker. 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 Amplifier redundancy – One amplifier can back up from one to eight amplifiers with the Q-Sys DAB-801 (DataPort Amplifier Backup).

Network Redundancy

Both the Core and the I/O Frame have two network ports, LAN A (primary), and LAN B (backup). The LAN B port on I/O Frame becomes active when it is configured in Q-Sys Designer as "Is Network Redundant" and connected. Because the I/O Frame 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 Core and I/O Frame 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 Install/Uninstall Procedure

Card installation should only be done by a trained and qualified technician.

Tools needed: Phillips screwdriver | ESD wrist strap (ground strap)

1. An ESD wrist strap must be worn throughout the install/uninstall procedure. The end of the wrist strap should be connected to an unpainted surface on the product chassis such as the ground stud.
2. Disconnect the AC mains power cord.
3. Remove the sheet metal screws securing the lid to the Q-Sys I/O Frame chassis. Remove the lid by lifting it approximately 1" at the rear of the chassis and sliding it back from the front. (— Figure 8)
4. Locate the Q-Sys I/O Card to be replaced. Remove the ribbon cable from the card by gently lifting up on the plastic ribbon cable locking tab on the connector at the edge of the card. Ensure that the cable edge does not get damaged. (— Figure 9)
5. Remove the two screws securing the Q-Sys I/O Card mounting bracket to the rear of the chassis. Remove the bracket. (- Figure 10)

NOTE: Note: in order to remove an I/O Card in position C or D, first uninstall the appropriate card above in position A or B.

1. For Q-Sys I/O Cards in positions A or B, remove the four Phillips head screws securing the card and remove the card. For cards in positions C or D, remove the card above, then remove the four hex standoffs and remove the card to be replaced.
2. Install the new Q-Sys I/O Card by reversing steps 4 through 6. Be sure to align and secure the rear panel mounting bracket before the hex standoffs or card-securing screws are completely tightened.
3. Reattach the ribbon cable to the Q-Sys I/O Card. Make sure that the edge of the ribbon cable is properly aligned with the connector mating surface. The blue band on the ribbon cable should be facing upward. Engage the ribbon cable locking tab on the connector by gently pressing down on the locking tab.
4. If replacing a blank Q-Sys I/O Card with an audio I/O Card, the ribbon cable in step 8 must also be connected to the Q-Sys I/O Frame main circuit board. To do this, locate the connector corresponding to the appropriate I/O Card position (connector labels on the main board match the I/O Card positions printed on the product rear panel). Insert the ribbon cable into the main board connector by first lifting the plastic ribbon cable locking tab on the connector. Then align the ribbon cable with the connector contacts and insert the edge of the ribbon cable into the connector slot. (- Figure 11) The blue band on the ribbon cable should face the system power supply. Make sure the ribbon cable locking tab on the connector is engaged by holding the ribbon cable in place and gently pressing down on both sides of the locking tab simultaneously until the tab locks in place. (- Figure 11)

Qualified 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: Refer to the Q-Sys Online help on the QSC website for the latest list of switches. (http://www.qscaudio.com/products/software/QSys/WebHelp/)
