Page 7: Introduction
Terms Used in this Manual The terms “amplifier” and “power amplifier” are used interchangeably in this manual to refer to all of the XPA models. “XPA 1002” refers to the 1002 and the 1002 Plus. ”XPA 2001” refers to both the XPA 2001-70V and the XPA 2001-100V. - Page 8 2001 series to be remotely controlled using the optional Extron VCM 100 Series volume and mute or VC 50 volume controllers. Bridgeable outputs — The power output of the XPA 1002 and XPA 1002 Plus can be effectively doubled by bridging the output. A mono source is wired to both the left and right input while the output is wired for bridged operation.

(such as the use of power strips). Rack Mounting The XPA 1002 series and XPA 2001 series can be mounted in a rack shelf using the optional RSU 129 1U Universal rack shelf or the 1U Basic rack shelf, as follows. -
Page 12: Flexible Conduit Adapter Kit Installation
Rack Mounting Ventilation Recommendations Excessive heat can decrease the optimal lifetime of the power amplifier. An over temp indicator LED on the front panel of the amplifier lights red whenever the recommended Front Panel Features and Operation operating temperature has been exceeded (see on page 9). -
Page 13: Installing The Flexible Conduit Kit
UL Requirements The UL requirements listed below pertain to the installation of the flexible conduit onto a XPA 1002 or XPA 2001. • This unit is not to be used beyond its rated voltage range. - Page 14 Remove the 2 screws holding the hot (Line) and neutral wires from the terminal block on the PCB (see figure 6).

High pass filter (HPF) toggle switch (XPA 2001 series) — Use a small screwdriver to toggle this recessed two-position switch. Setting the switch to 80 Hz (default) prevents the saturation of 70 V and 100 V speaker input transformers by low frequency signals. -
Page 24: Controlling Multiple Amplifiers With One Volume Controller
Controlling Multiple Amplifiers with One Volume Controller Several XPA 1002 and XPA 2001 series units can be daisy-chained so that one volume controller can simultaneously regulate the volume of all the amplifiers. NOTES: • As additional amplifiers are added to the daisy chain, the sensitivity of the volume potentiometer will change. -
Page 25: Bridged Mono Output
Bridged Mono Output The power output of the XPA 1002 and XPA 1002 Plus can be effectively doubled by bridging the output. Bridging allows power to be output in mono at 200 watts at 8 ohms. ATTENTION: Failure to follow these instructions may result in damage to the unit. -
