2.3 Proper Cooling Considerations 

 
Because CVA50-1 Priority PA amplifiers regulates their temperature 
using convection cooling and no fans, the amplifiers 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 along the surfaces of 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 

 
Your CVA50-1 Priority PA amplifier is provided with a 3-pin Euro Block 
connector for its input connection. This connector will accept both bal-
anced or unbalanced connections, however some modifications must 
be made for an unbalanced connection. See the next two sections for 
instructions on connecting your amplifier to its input source. 
 
 

2.4.1 Balanced Input Connections 

 
When using a balanced input source and connector, you must ensure 
that the hot, cold, and ground pins of the connector are matched up to 
the +, -, and ground pins of the CVA50-1 Priority PA Euro Block con-
nector respectively.  Diagrams have been provided for standard XLR 
and TRS connectors. Please refer to the manual of your input source in 
case it does not follow the standard pin-out. 

 

NOTE: The CVA50-1 Priority PA amplifiers does not accept 
TRS inputs wired for a stereo source. TRS inputs should 

only

 be used for balanced mono inputs.
