CONTROLS AND DISPLAYS

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.DC TRIGGER OUTPUT TERMINALS

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

7.POWER INPUT (AC IN)

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

8.IR INPUT JACK

•Use this jack to connect external IR sensors.

9.RS-232 PORT

•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.)
