FCC Statement For CXD-Q 4.3 and CXD-Q 4.5 NOTE: This equipment has been tested and found to comply with the limits for a Class A digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference when the equipment is operated in a commercial environment.
Rack-Mount the Amplifier 1. Secure the amplifier in the rack with eight screws (not supplied), four in front, four in back. — Figure 1 — Unpacking There are no special unpacking instructions. You may want to keep the shipping material for the unlikely event that the amplifier should need returning for service. Package Contents 1. Quick-Start Guide TD-000350-00 5. Euro-style Connector Plug, 3-pin (4) 2. Warning Information Sheet TD-000420-00 6. Euro-style Connector Plug, 8-pin (1) 3.

Connections LAN A LAN B Q-Sys Q-LAN Connect the amplifier LAN A, and if available, LAN B, to the Q-LAN network. (Figure 4) Refer to your Q-Sys documentation for network requirements and connection detail. — Figure 4 — Unbalanced Balanced Inputs The analog inputs are converted to digital audio in the CXD-Q amplifiers and then routed to the Q-Sys Core over the network. The digital signals show up in Q-Sys Designer at the CXD-Q input component where they can be routed as needed.

Amplifier Control NOTE: The following scenarios assume that the amplifier is connected to the Q-Sys Core via Q-LAN. When the amplifier is not connected to the Q-Sys Core, it is in a Fault mode, and not operational. NEXT & PREV Buttons • Rear power switch is off, the amplifier is not operable. The power switch is the AC Mains disconnect. • The power button is not illuminated. PREV • Navigates forward and backwards through the screens.
Inputs and Outputs The CXD-Q amplifiers have four Mic/Line Inputs and four amplified Outputs on the rear of the amplifier. The Inputs and Outputs on the rear of the amplifier are not connected inside the amplifier. The analog inputs are converted to digital audio in the CXD-Q amplifiers and then routed to the Q-Sys Core via Q-LAN (LAN A, LAN B). The digital signals are brought into the design in the CXD-Q Amplifier Input component.
4. FIRMWARE: The Q-Sys Designer firmware version. To update the firmware: a. The version you want to use must be installed on your PC, b. The amplifier must be connected to the network, and turned on. c. Open the Q-Sys design containing the amplifier and select "Save to Core and Run" from the File menu. d. The amplifier Q-LAN processor and any other Q-Sys peripherals in the design are automatically updated. 5. GAIN A - D: Displays the current Gain setting for each channel.
1 Output Gains Screen 2 The Output Gains screen provides a quick overview of all outputs and is the screen on which GAIN adjustments are made. Use the NEXT or PREV buttons to access this screen or, press one or more of the SEL buttons to access the screen and make GAIN adjustments for the selected channels. If you press one or more of the SEL buttons, and do not make any GAIN adjustments, this screen remains visible for a short time the returns to the previous screen. 3 OUTPUT GAINS AB -45.0 dB -8.

Heat Loss Charts Heat losses are the thermal emissions from an amplifier while it is operating. It comes from dissipated waste power—i.e., real AC power in minus audio power out. Measurements are provided for various loads at idle, 1/8 of average full power, 1/3 of average full power, and full power, with all channels driven simultaneously. For typical usage, use the idle and 1/8 power figures.
