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.
