2.3 Proper Cooling Considerations 

 
Because CVA Series amplifiers regulates their temperature using con-
vection cooling and no fans, the amplifiers 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 
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 (NET+ Models Only) 

 
Your CVA Series amplifier is provided with a 3-pin Euro Block connector 
for its input connection. This connector will accept both balanced or 
unbalanced connections, however some modifications must be made 
for an unbalanced connection. See the next two sections for instruc-
tions 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 CVA Series’ Euro Block connector re-
spectively.  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 CVA Series of amplifiers do not accept TRS in-
puts wired for a stereo source. TRS inputs should 

only

 be 

used for balanced mono inputs.
