Introduction
This user manual provides data about the Christie Vive Audio CDA2/CDA3 Professional Power Amplifiers controls, installation, and specifications.
Overview
Christie Vive Audio CDA2/CDA3 Professional Power Amplifiers utilize an advanced design that reduces the weight of the amplifier significantly while increasing output power, reliability, and thermal efficiency.
Christie Vive Audio CDA2/CDA3 Professional Power Amplifiers are designed with a resonant switch- mode power supply and a high-speed class D topology that yields superior audio resolution and efficiency.
Advanced technology and extensive protection circuitry allow operation with greater efficiency into difficult loads and power conditions. The ACL (Automatic Clip Limiting) circuitry provides trouble-free operation into loads as low as 2 ohms. ACL protects loudspeaker drivers and ensures that sonic integrity is maintained, even in extreme overload conditions. The CDA’s high- efficiency design allows the amplifier to operate at very low temperatures, and does not require massive heat sinks for cooling.

Indicators
AC Power Switch
Rack Mounting Ears
Indicates the operating status of each of the channels and warns of possible malfunction. There are 5 indicators for each channel:
• ACL (automatic clip limiting) - indicates clipping. If the light is flashing quickly and intermittently, the channel is at the clip threshold. Gain reduction is automatically employed to prevent severely clipped waveforms from reaching the loudspeakers.
• SIG (signal) - indicates that an output signal of 4 volts RMS or more (0.1 volt or more at the input with 0 dB attenuation and standard x 40 voltage gain) is being produced by the channel. The signal is reaching and being amplified by the amplifier.
• TEMP (temperature) - indicates an unstable thermal condition. The amplifier protection will activate and shut down the affected channel. The light will remain illuminated until a safe operating temperature is achieved.
• DC (direct current) - indicates abnormal operating conditions. The light illuminates when conditions arise that will damage the loudspeaker driven by that channel. The amplifier automatically attempts to restart to correct the condition. If the amplifier does not return to a normal operating status, contact your local authorized service center.
• ACTIVE - indicates that the channel is operational. The light illuminates under normal operation and remains on, even when the channel is in ACL gain reduction. If the light is off, there is no signal at the output connectors.
Turns the power on and off. This is a combination magnetic circuit breaker and switch.
Provides mounting holes for rack installation.
Rear Panel
If the PARALLEL or BRIDGE input mode is selected, the signal input to channel A of the power amp is also available as an output on the channel B input connector. This allows you to patch input signals between multiple amplifiers.

• CH. B - allows a twist lock connector to be connected to the channel B output.
• BRIDGE - allows for a twist lock connector to be connected to the bridged amplifier output.
• CH. A - allows a 2-pole or 4-pole twist lock connector to be connected to the channel A output. Connecting a 4-pole twist lock connector provides the outputs of both channels A and B on the corresponding poles of the 4-pole connector.
• Provides the connecting inputs and input controls. Input connections are made using the 3-pin XLR (pin 2+) or 6.3 mm (1/4 in.) plug combination connectors on the rear panel of the amplifier. The inputs are actively balanced.
The following channel modes are available:
• SUB (subwoofer) - activates the low pass filter for the corresponding channel.
This Linkwitz-Riley filter limits the frequencies sent to the associated amplifier channel to those frequencies below 100 Hz. in situations where separate subwoofer cabinets are being used, this position indicates connecting the subwoofer speaker cabinet to the channel associated with the subwoofer switch.
• FULL-RANGE - allows all frequencies to pass to the amplifier. This setting is normally used when connecting a full range speaker enclosure to the amplifier’s output.
• HIGH-OUT (switch high pass) - activates the high pass filter for the corresponding channel. This Linkwitz-Riley filter limits the frequencies sent to the associated amplifier channel to those frequencies above 100 Hz. In situations where separate subwoofer cabinets are being used, this position would indicate connecting the mid-high frequency speaker cabinet to the channel associated with the high pass switch.
The following channel input mode switches are available:
• PARALLEL - routes the signal input of channel A to both channel A and channel
B outputs. Use this to route the single input signal to each of the discrete amplifier outputs.
• BRIDGE - combines both amplifier channels together for a powerful singlechannel amplifier. Routes the signal connected to channel A input to the bridged amplifier channels. This is required when the single input signal is to be routed as the bridged amplifier output.
• STEREO - provides independent channel operation. Routes the signal connected to channel A input to the amplifier channel A output and the signal connected to channel B input to the amplifier channel B output. This is required when discrete inputs to channels A and B should be routed to the corresponding amplifier outputs.
Do not adjust the mode when the amplifier is turned on.
Provides air flow through the cooling fins of the channel heat-sinks, to dissipate the heat of the power devices. Air exhausts through the front panel slots. Fan speed is automatically controlled; the fan speed increases as the heat-sink temperature rises, and slows as the temperature lowers. Make sure these vents remain clear to allow unrestricted air flow.
If a channel’s heat-sink surpasses the maximum temperature limit, the high temperature sensing circuit will idle the channel until a safe operating temperature is restored. If the power supply overheats, the high temperature sensing circuit will idle both channels until a safe operating temperature is restored.

AC mains. Connect the IEC line cord to the AC power inlet on the rear panel of the amplifier.
• Verify that the circuit breaker for the mains circuit is open. Reset the circuit breaker, then turn the amplifier power on again. If the AC mains breaker continues to open, check the voltage and amperage (d) of the circuit.
• Verify that the circuit breaker has the correct voltage and amperage
(d). If required, have a qualified electrician replace the circuit breaker.
If the circuit breaker continues to open, send the amplifier to an authorized service center for repair.
• Check the amplifier indicators:
• If the ACTIVE indicators are lit for each channel, verify that the amplifier is receiving power. See The amplifier power will not turn on. on page 13.
• If the SIG (signal) indicators are lit or blinking, check the level of the input signal source.
• If the TEMP (temperature) indicators are lit for either channel, the amplifier has overheated and idled one or both channels. See The amplifier is overheating. on page 14.
• If the DC (direct current) indicators are lit for either channel, an abnormal condition exists within the amplifier or the load it is driving. If the channel does not reset and the DC indicators remain lit, send the amplifier to an authorized service center for repair.
• Check the amplifier mode:
• If the amplifier is in PARALLEL or BRIDGE mode and the input signal is connected to CH B, connect the input signal is CH A. See Input
Connections on page 8.
• If the amplifier is in BRIDGE mode and the output connections is made to CH A or CH B, use the center BRIDGE output connector to connect the loudspeaker. See Bridge Mode Connections on page
11.
• Verify that the attenuators on the front panel are turned up. Turn the attenuators up until you hear output from the loudspeakers.
• Check all connections between the amplifier and loudspeakers. Make sure that the twist lock connectors are fully-inserted and seated. The connectors must be inserted and turned 1/4” clockwise until they lock in position. If screw terminal connections are used at the loudspeaker inputs, make sure the cables are attached and do not cause a short between the poles of the loudspeaker inputs.

The connectors must be inserted and turned 1/4” clockwise until they lock in position. If screw terminal connections are used at the loudspeaker inputs, make sure the cables are attached and do not cause a short between the poles of the loudspeaker inputs.
• Check the amplifier indicators:
• If the SIG (signal) indicators are lit or blinking for both channels, make sure the channel’s input signal is present and at a sufficient level to drive the input.
• If the TEMP (temperature) indicators are lit for either channel, the amplifier has overheated and idled one or both channels. See The amplifier is overheating. on page 14.
• If the DC (direct current) indicators are lit for either channel, an abnormal condition exists within the amplifier or the load it is driving. If the channel does not reset and the DC indicators remain lit, send the amplifier to an authorized service center for repair.
• Check the amplifier mode:
• If the amplifier is in STEREO mode, make sure there is signal input to CH A and CH B. See Input Connections on page 8.
• If the amplifier is in STEREO or PARALLEL mode, make sure that one of the loudspeaker connections is not connected to the BRIDGE output.
• Check if the low-pass filter is engaged on either channel. Make sure the input mode selector switch is set to the correct mode (Full Range is the default mode).
• Verify that the NL4 twist-lock connector is wired correctly if the loudspeaker is biamped through the CH A output connection. See
Biamp Mode Connections on page 10.
• Check if the high-pass filter is engaged on either channel. Make sure the input mode selector switch is set to the correct mode (Full Range is the default mode).
• Verify that the NL4 twist-lock connector is wired correctly if the loudspeaker is biamped through the CH A output connection. See
Biamp Mode Connections on page 10.
• Verify that there is adequate ventilation around the amplifier. Make sure there is 31 cm (12 in.) clearance at the front and the back of the amplifier.
• Verify that the amplifier cooling vents are not blocked.
• Check the cooling fan at the rear panel of the amplifier to make sure it is working. If the power amplifier has overheated, the TEMP indicators are lit, and the fan is not operating, cease operation of the amplifier and send it to an authorized service center for repair.
• Verify that the amplifier is operating within its rated impedance. Check the loudspeaker load being presented to the amplifier outputs. The minimum load impedance for the CDA2 and CDA3 power amplifier is 2 ohms. Loudspeaker loads below 2 ohms stereo (4 ohms for each channel) or 4 ohms bridged cause the amplifier to overheat. If overloaded, correct the loudspeaker configuration or load the resume operation.
