The CVA50MX-1 / CVA50PMX-1 has mount holes on both the top as well as the side of the unit which can be used with the AV-Pole bracket available from Stewart Audio.
Part Number: AV-Pole
2.2.2 Product Dimensions
2.3 Proper Cooling Considerations
Because the CVA50MX-1 / CVA50PMX-1 regulates its temperature using convection cooling and no fans, the amplifier must be given adequate space to allow for proper airflow. Do not stack the amplifiers on top of each other or mount it in a way that other equipment will block airflow through the case.
CAUTION: Inadequate airflow to the amplifier can cause the amplifier to overheat and potentially become damaged in the process. Be sure to provide plenty of air space to allow for convection cooling.
2.4 Input Connections
The CVA50MX-1 / CVA50PMX-1 has 4 inputs which are mixed into the final mono output. The first input channel is for a balanced microphone and the rest are stereo, unbalanced inputs. All stereo inputs are summed to mono prior to being mixed.
CVA50MX-1-xxV (70V or 100V):
When a signal is applied to input 1, inputs 2-4 will be ducked as per the setting of the "duck" control. The level for each input channel is set with the corresponding control. The master volume control and remote volume set the level of all inputs including input 1.
CVA50PMX-1-xxV (70V or 100V):
When a signal is applied to input 1, inputs 2-4 will be ducked as per the setting of the "duck" control. The level for each input channel is set with the corresponding control. The master volume control and remote volume set the level of inputs 2-4. The input 1 level control is independent and not affected by the master or remote controls.
2.4.1 Input 1—Microphone
The first input channel is for a balanced microphone and includes an adjustable pre-gain as well as phantom power for the use of condenser microphones. A pin-out diagram compatible with the CVA50MX-1 / CVA50PMX-1 is included below. For pre-gain adjustment and phantom power, refer to Section 3.2.2.
2.4.2 Input 2—RCA
The second input channel is a stereo RCA jack which is then summed to mono before the final output. Refer to the diagram below for wiring directions.
2.4.3 Input 3—Stereo Euroblock
The third input channel is a euro block connector which can be wired to any unbalanced input. Should you be wiring up a stereo source, use both the left and right pins of the connector. A mono source will only require the use of the ground and left pins.
2.4.4 Input 4—Stereo 3.5mm
The second input channel is a stereo RCA jack which is then summed to mono before the final output. Refer to the diagram below for wiring directions.

*CVA50MX-1:
When a signal is applied to input 1, inputs 2-4 will be ducked as per the setting of the "duck" control. The level for each input channel is set with the corresponding control. The master volume control and remote volume set the level of all inputs including input 1.
*CVA50PMX-1:
When a signal is applied to input 1, inputs 2-4 will be ducked as per the setting of the "duck" control. The level for each input channel is set with the corresponding control. The master volume control and remote volume set the level of inputs 2-4. The input 1 level control is independent and not affected by the master or remote controls.
3.2.1 Indicators
The CVA50MX-1 / CVA50PMX-1 has 3 front panel LED indicators. The power indicator (Pwr) will illuminate bright blue when power is supplied to the amplifier. If power is supplied but the LED is off, this means that the amplifier is in sleep mode. Once signal is detected by the Signal Sense circuit, the LED will turn back on.
The Signal Present indicator (Sig) will illuminate green when signal is detected on any of the 4 input channels.
The last indicator is the Clip/Distortion LED. This indicator means that one of the input signals is too "hot" and will sound distorted when amplified. To fix this, the gain should be reduced at the preamp or mixer level.
3.2.2 Controls
All CVA50MX-1 / CVA50PMX-1 controls are located on the rear of the unit. There is no power switch so the CVA50MX-1 / CVA50PMX-1 will turn on whenever power is supplied to it. The CVA50MX-1 / CVA50PMX-1's Signal Sense Technology (SST™) will power up the amplifier from sleep when a signal is detected. After 5 minutes without an input signal the amplifier will go into sleep mode.
The front panel contains a volume control for each input channel as well as a master volume. It also contains 2 recessed controls for the microphone ducking. For more information on this, refer to section 3.3.2.
Note: For the highest sound quality, leave the master volume knob as low as possible and increase the channel volume before increasing the master volume.
The rear panel of the CVA50MX-1 / CVA50PMX-1 includes a set of 4 DIP switches which control both the pre-gain of the microphone as well as the +48VDC phantom power.
The “Mic Gain” setting will adjust for the sensitivity of microphones by different manufacturers beyond what the volume control offers. If the microphone is generally too loud, select the “High” setting by pushing both switches up. If the microphone is generally too quiet, select the “Low” setting by pushing both switches down.
If you are using a condenser microphone requiring +48VDC phantom power to operate, slide both switches down. Otherwise, leave the switches in the "up" position.
The diagram below is an example of a condenser microphone (requiring phantom power) and is loud enough without additional pre-gain supplied by the amplifier.

Gain Pwr
High Off
Low On
3.3 Special Features
3.3.1 Signal Sense Technology™
Stewart Audio's Signal Sense Technology™ puts the amplifier into an Energy Star compliant sleep mode after five minutes of no signal being detected on any input channels. The blue Power Indicator LED will go off and the amplifier will wait for signal to be present again. Once signal is present, the amplifier will return to normal operation.
3.3.2 Microphone Ducking
The CVA50MX-1 / CVA50PMX-1 includes a ducking feature which allows the microphone channel (Input 1) to talk over the other 3 channels. When a loud enough sound is detected on Input 1 it will lower channels 2-4 by a set amount. Both the sound threshold to activate the ducking (Ducking Sensitivity) and the amount the other channels are lowered (Ducking) are configurable via knobs on the front panel.
To properly adjust the ducking you should first play a typical source audio (song, movie, etc.) through any of the channels 2-4. Once this is playing, connect a microphone to channel 1 and begin to speak at a typical level. You should hear the source audio lower when you speak into the microphone. Using a small screwdriver, adjust the "Ducking Sensitivity" knob to set the sound threshold which activates the ducking. Next, adjust the "Ducking" knob to set the amount the other channels should be lowered. Turning the knob all the way counter-clockwise will mute channels 2-4 when ducking is activated.
4 Troubleshooting
Problem: Power indicator does not turn on.
Procedure: Check that the amplifier is plugged into a live outlet. After you have ensured that it is not a power issue, disconnect any speakers. If the amplifier turns on after a few seconds delay, then the problem is in the output connection. Check wiring and speakers for short circuits.
Problem: No output on one or both channels; Power indicator is lit.
Procedure: Check that level controls are not turned down. Check that input and output connections are secure. Refer to section 2.5 to ensure that you have properly connected your speakers. Ensure signal present LED is flashing to denote a signal. If there is no signal detected check signal source and that level controls are set high enough.
Problem: Microphone level is too low even after adjusting level knob
Procedure: Refer to section 3.2.2 to adjust the gain switch on the rear of the amplifier.
Problem: Channels 2-4 cut out while speaking into the microphone
Procedure: This is part of an intended feature calling ducking. Refer to section 3.3.2 to adjust this to a more acceptable level.
Problem: Amplifier overheats and/or shuts off.
Procedure: Review section 2.3 on proper cooling procedures. Check the signal lights on the front of the amplifier to see if the signal is overdriving (the Clip light flashes red frequently). Overdriving the amplifier for extended periods of time can cause a thermal shutdown.
4 Troubleshooting (Cont.)
Problem: Output sound is distorted or cracking.
Procedure: Check all cables for damage or loose connections and reduce the gain on the input signal at the mixer or preamp level. Replace the cables and loudspeakers temporarily to see if this resolves the problem. If problem still exists, contact your Authorized Dealer for service.
