XTRA™Half-Rack Series

Audio Power Ampliers • Setup Guide

WARNING: May cause serious injury. Installation and service must be performed by authorized personnel only. These

products must be used with UL approved, grounded, electrical boxes.

This guide provides startup instructions for an experienced installer to set up and operate the XPA 1002 or XPA 2001 Series

audio power ampliﬁer. All references are to the XTRA™Half-Rack Series User Guide which can be found on the Extron

website.

Step 1

Be sure that power to the ampliﬁer is turned off ﬁrst.

NOTE: Adjust the audio level to =(full attenuation) prior to the ampliﬁer being powered back up in step 5(see

“Rear Panel Features and Operation” in the User Guide).

Turn off all other equipment and disconnect the power cords. Verify that the ampliﬁer is disconnected from the power

source before proceeding.

Step 2

For diagrams of typical application examples, see “Application Examples” in the User Guide. For further mounting

instructions, see “Mounting the XPA 1002 and XPA 2001” in the User Guide.

Step 3

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.

Wire the source output to the ampliﬁer input 3.5 mm captive screw connectors as shown in the following illustration (see

“Rear Panel Features and Operation” in the User Guide).

NOTE: The output power of the XPA 1002 can be effectively doubled by using only one input channel and bridging the

output. The XPA 1002 outputs 200 watts @ 8 ohms in bridged mode (see “Bridged Mono Output” in the

User Guide for wiring instructions when bridging the XPA 1002).

Do not tin the wires!

NOTE: For mono input on the XPA 2001, only the left channel needs to be wired; no jumpering to the right channel is

needed. The left and right inputs of the XPA 2001 are summed internally to mono.

Step 4

Wire the speakers to the output connector of the ampliﬁer using the included 4-pole (XPA

1002) or 2-pole (XPA 2001-70V and XPA 2001-100V) captive screw plug as shown to the

right. See “Rear Panel Features and Operation” in the User Guide.

Step 5

ATTENTION: The ampliﬁer must be powered on last.

Reconnect all power cords and switch on all other equipment before powering on the power ampliﬁer. The front panel

power LED of the ampliﬁer lights green.

Step 6

Adjust the audio attenuation using the rear panel adjustment knobs as shown below. See “Rear Panel Features and

Operation” in the User Guide.

NOTE: On some models, this adjustment is referred to as “level”. The function is the same, whichever way your product

is labeled.

Step 7

On XPA 2001-70V and XPA 2001-100V models, use a Tweeker to toggle the high pass ﬁlter switch between

off (no ﬁltering) and 80 Hz (default). Setting the switch to 80 Hz prevents the saturation of speaker input

transformers by low frequency signals.

Step 8

Check the limiter/protect and signal LEDs located on the front and rear panels if problems are encountered.

See “Rear Panel Features and Operation” in the User Guide.

Step 9

The 3.5 mm 5-pin captive screw remote control port (shown to the right) is used to control

volume and standby mode through contact closure. Standby mode turns off all output,

although the XPA is still receiving power.

See “Front Panel Features and Operation” in the User Guide for more information.

NOTE: The remote control port may be labeled one of two ways (see the images above). The wiring and function are

the same, whichever way your product is labeled.
