About this Document
NOTE: This Quick Start Guide is based on the basic configuration as the amplifier comes from the factory.
For detailed instructions for custom configurations refer to the CXD-Q User Guide (TD-001522).
This document covers the basic instructions to get your amplifier connected to the Q-SYS system and operational.
There are four different amplifiers covered by this document. The common name for all four amplifiers is CXD-Q. The
individual names are: CXD8.4Q, CXD8.4Qn, CXD8.8Q, and CXD8.8Qn.

Inputs
The Qn models do not have analog inputs, they get their audio input
exclusively over the Q-LAN Network.
1. Wire the audio line-level source to each Euro-style connector (supplied)
required by your design. You may use either balanced inputs (— Figure 4) or unbalanced inputs (— Figure 5).
2. Plug the connectors into the appropriate receptacles (Routable Inputs 1 through 8) — Figure 6.
WARNING!: Do not apply AC power to the amplifier at this time.
3. Make sure the Power Switch is in the off (down position) before
proceeding. (— Figure 7)
4. Connect the IEC power cord to the AC receptacle on the rear of
the amplifier. (— Figure 7)

Outputs and Output Configuration
The CXD-Q amplifiers have two sets of four-channel outputs that are configured independently. The configuration of the
amplifier is defined in Q-SYS designer software and is "pushed" into the physical amplifier when the Name and Type of
amplifier in the design matches the Name and Type of physical amplifier. When the output configuration of the amplifier
changes, the Outputs to the loudspeakers change accordingly.
Use the diagrams shown in — Figure 9 thru — Figure 11 as a reference for planning your loudspeaker configuration.
Refer to — Figure 12 for how to connect the wiring based on your configuration. After connecting the loudspeakers to the
outputs, you may turn the amplifieron.
CAUTION!: If you change the output configuration of the amplifier you must change the loudspeaker
connections before applying power to the amplifier!
— Figure 9 through — Figure 11 are examples of the three types of output configurations: Separate, Bridged and
Parallel. The tables to the right and left of the loudspeaker connections (rear panel of the amplifier) give all the possible
configurations and their connections.

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 unless previously configured
for fail-over or standalone mode as part of a
Q-SYS design. With the exception of the Power
Switch, found on the rear panel, all of the
following controls are on the front panel.
Refer to — Figure 13 for location of front-panel controls.
Off Mode
• Rear-panel power switch is off, the
amplifier is not operable. The power
switch is the AC Mains disconnect.
• The front-panel power button (1) is
notilluminated.
• Turn the power switch to ON. The
amplifier enters the mode in which it was
when power was removed – Run, Mute All, orStandby.
Run Mode
• From Standby or Mute All mode, press and
release the power button on the front panel.
The amplifier is in Run Mode.
• The power button (1) is illuminated green.
• The amplifier is fully operable; audio can pass.
Standby Mode
• From Mute All or Run mode, press and hold
the power button
(1)
on the front panel for
approximately four seconds.
• The power button illuminates solid red.
• The amplifier is not operable; audio will not pass.
Mute All Mode
• From the Run Mode, quickly press and release the
power button (1).
• The power button flashes red, all output Mute buttons (2) are red.
• The amplifier output is disabled, but the front panel is
fullyoperable.
SEL Buttons (3)
• Channel gain can be adjusted from the Q-SYS
Designer software or from the front panel of the amplifier.
• Use the SEL button to select one or more than one
channel to change gain settings. All selected channels
will change at the same time.
• If two or more outputs are bridged or in parallel, pressing
one button in the group selects all channels in that
bridged or parallel group.
NEXT (4) and PREV (5) Buttons
• Navigates forward and backwards
through the screens.

Signal Flow
CXD8.4Q and CXD8.8Q
The CXD8.4Q and CXD8.8Q amplifiers have eight MIC/LINE Inputs and eight amplified Outputs on the rear of the
amplifier. The Inputs and Outputs are not physically (or electrically) connected internally giving you the flexibility to use any
available source in Q-SYS for the amplified outputs, and to route the inputs to any output. The inputs and outputs can be
connected in your Q-SYS design as shown in — Figure 14.
The analog inputs are converted to digital audio in the amplifiers and then routed to the Q-SYS Core via Q-LAN (LAN A,
LAN B). The digital signals are brought into the design via the amplifier's Mic/Line Input component. From the Mic/Line
Input component the signals can be sent anywhere within the Q-SYS system.
In the Q-SYS Core digital signals are sent to the amplifier's Output component and fed from the Q-SYS Core via Q-LAN
to the analog amplified outputs of the amplifier. The Output component can have two to eight outputs depending on the
configuration of the amplifier in Q-SYS Designer. The desired configuration is selected in the Properties menu for that
amplifier. When the amplifier's configuration is changed, all of the outputs are placed in a "mute all" state. You must
un-mute all in the Amp Output component's control panel or on the amplifier's front panel.
CXD8.4Qn and CXD8.8Qn
Refer to — Figure 15
The Qn model amplifiers have no analog inputs. The input signal utilized to drive the amplifier channels must be virtually
wired in Q-SYS Designer. The Qn models have eight amplified Outputs on the rear of the amplifier.
In the Q-SYS Core digital signals are sent to the amplifier's Output component and fed from the Q-SYS Core via Q-LAN
to the analog amplified outputs of the amplifier. The Output component can have two to eight outputs depending on the
configuration of the amplifier in Q-SYS Designer. The desired configuration is selected in the Properties menu for that
amplifier. When the amplifier's configuration is changed, all of the outputs are placed in a "mute all" state. You must
un-mute all in the Amp Output component's control panel or on the amplifier's front panel.

tooperate.
3. STATUS – displays the current status of the amplifier both in text
and color. The following is a list of possible status colors, and some
example conditions.
• OK – green – audio is good, hardware is good.
• Compromised – orange – audio is good but a redundancy mechanism is active (one LAN down but the other is still
up) or a non-fatal hardware problem exists (fan speed, high temperature, low AC voltage, output load, amplifier is in
Protect mode, etc.)
• Fault – red – audio is not passing, or hardware is malfunctioning or mis-configured (amplifier power off, audio
streams broken, amplifier fault, loudspeaker short circuit, etc.)
• Initializing – blue – In the process of initialization, and design start. Audio is not passed.

OUTPUT GAINS Screen
Refer to — Figure 21
The Output Gain screens provides a quick overview of all outputs. In
addition, when this screen is displayed, you can make GAIN adjustments
on the amplifier's front panel. There is one screen for channels A–D and
one for channels E–H.
Use the NEXT or PREV buttons to access these screens or, press one or
more of the SEL buttons to access the screen.
1. The highlighted background indicates that the Channel is selected by
the SEL button.
2. Channel – the channels display according to the configuration of the
amplifier.
3. Output Gain – the output gain can be controlled in two places: the GAIN knob on the amplifier front panel and with
the Gain control in the amplifier's Output component in the Q-SYS design.
4. Q-LAN Input Level – the level of the audio signal applied to the Output component in the Q-SYS design. The CXD-Q
Output component is the connection to the output section of the amplifier.
5. VOLTS – the voltage applied to that output.
6. Output B is combined with Output A – (AB or A+B), the slot for Output B is blank.
To Make GAIN Adjustments:
a. Use the SEL button to select one or more channels. You can select any or all channels.
b. Use the GAIN knob to make adjustments on the output gain of the selected channels.
NOTE: If the gains were the same when you select multiple channels the gains remain equal as you adjust
them. If the gains are different, they keep their relative separation until one reaches a limit. At this point the
other channel(s) continue to change until they reach the limit.
NOTE: 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 then returns to the previous screen.
Output Screens
Each group of outputs has a dedicated screen. — Figure 22 is an example
of OutputsA–D.
1. Output channel identifiers A– D.
2. DAC – when illuminated, this indicates that the signal to the D to A
Converter is larger than can be reproduced and a limiter has been
engaged to prevent clipping. This is an indication that the gain
structure is not correct.
3. PROTECT – when illuminated, this indicates that the channel is in
Protect Mode. Usually due to driving too low of an impedance for
toolong.
4. LIMIT – when illuminated, this indicates the amplifier limiter is active.
This occurs if the signal is driving the power, current, or voltage above the amplifier rated values or due to thermal
limiting.
5. SHORT – when illuminated, this indicates the output is shorted. A short can be triggered by either of the following:
a. Output impedance is below ¼ Ohm for more than 1 second.
b. Output voltage is less than 50% of what the DSP was expecting for more than 1 second.
6. Displays the temperature, in Centigrade, of the associated channel.
