Audio Power Amplifiers • Setup Guide  
WARNING: May cause serious injury. Installation and service must be performed by experienced 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 amplifiers. All references are to the XTRA Series Half-Rack User Guide which can be found on www.extron.com.  
Step 1 — Powering Down Equipment  
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.  
Turn off all other equipment and disconnect the power cables. Verify that the amplifier is disconnected from the power source  
before proceeding.  
Step 2 — Mounting and Applications  
For diagrams of typical application examples, see “Application Examples” in the User Guide. For further mounting instructions,  
see “Mounting the XTRA Series Amplifier” in the User Guide.  
Step 3 — Captive Screw Audio Cable Wiring  
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.  
NOTE: The output power of the XPA 1002 and XPA 1002 Plus can be effectively doubled by using only one source channel  
and bridging the output. The XPA 1002 and XPA 1002 Plus output 200 watts @ 8 ohms in bridged mode (see  
“Bridged Mono Output” in the User Guide for wiring instructions when bridging the XPA 1002 or XPA 1002 Plus).

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 — Speaker Wiring

Wire the speakers to the output connector of the amplifier using the included 4-pole  
(XPA 1002 series) or 2-pole (XPA 2001-70V and XPA 2001-100V) captive screw connector as  
shown to the right.

Step 5 — Setting the High Pass Filter (HPF)  
On the 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.

NOTE: The high pass filter switch may be labeled one of two ways (see the images to the  
right). The function is the same, whichever way your product is labeled.
