2.3 Proper Cooling Considerations
Because the CVA50MX-1 / CVA50PMX-1 regulates its temperature us-
ing convection cooling and no fans, the amplifier must be given ade-
quate 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 independ-
ent 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.
