•XPA 4002-70V outputs 400 watts rms per channel on channels 1 and 2 for 70 V systems.

1.Power off — Turn off all equipment including the XPA amplifier by toggling the power off and disconnecting the power cord. Verify that the amplifier is disconnected from the power source before proceeding.

2.Mount the amplifier — For diagrams of typical application examples, see the “Application Examples” section in the user guide. For further mounting instructions, see the “Mounting the XTRA Series of Power Amplifiers” section in the user guide.

3.Wire the input — Wire the input to the 3.5 mm input connectors of the amplifier, as shown in the following illustration. See the “Rear Panel Features and Operation” section in the user guide for bridging information.

NOTE: Control signal ground pins may be labeled as or “G”. Audio ground pins may be labeled as or . The wiring and function are the same, whichever way your product is labeled.

NOTE: The wires must not be tinned: tinned wire does not hold tight in the captive screws and can break easily after several bends.

4.Wire the outputs — Wire speakers to the output connectors of the amplifier using the included 2-pole (70 V or 100 V) or 4-pole (8 ohm or 4 ohm) screw lock plug.
