5.  BALANCED MAIN OUTPUTS 

•  If your power amplifier is equipped with balanced inputs, it is generally best to use the 

balanced outputs on your preamplifier. A balanced signal from preamplifier to power 
amplifier will offer the highest possible performance with the best immunity from 

common-mode noise, such as radio frequency interference (RFI). The balanced output 

signal is made available by way of precision male XLR connectors (requiring female 

XLRs on the preamplifier end of the interconnecting cable). 

 

• 

The pin assignments of these XLR-type male outputs are:

 

 

Pin 1: Signal ground 

Pin 2: Signal + (non-inverting) 

Pin 3: Signal - (inverting) 

Connector ground lug: chassis ground 

 

Refer to your power amplifier's operating manual to verify that the pin assignments of 
its input connectors correspond to the CPA 1. If not, wire the cable so that the 

appropriate output pin connects to the equivalent input pin. 

 

6. 

 

•  Connect a device that needs to be triggered by DC + 12V. (CD player) 

 

•  Connect to an AC power supply using the included power supply cord. 

 

•  Use this jack to connect external IR sensors. 

 

•  The RS-232 port is used in conjunction with an external controller to control the 

operation of the CPA 1. (This is for custom installation use. Consult your dealer for 

more information.)
