Introduction About this Guide This guide contains information about the Extron® series of audio power amplifiers: the XPA 2002 two-channel stereo amplifier, the XPA 2002-70V two-channel, 70 V line distribution mono amplifier; the XPA 2002-100V two-channel, 100 V line distribution mono amplifier; the XPA 2003C-70V three-channel, stereo 4-ohm and 8-ohm, mono 70 V line distribution amplifier; the XPA 2003C-100V three-channel, stereo 4-ohm, 8-ohm, mono 100 V line distribution amplifier; and the XPA 2004 four-c
Features Extron Patented Class D Ripple Steering (CDRS™) technology — CDRS is an Extron patented technology that provides a smooth, clean audio waveform and an improvement in signal fidelity over conventional Class D amplifier designs. CDRS eliminates the high frequency switching ripple characteristic of Class D amplifiers, a source of RF emissions, which can interfere with sensitive A/V equipment such as wireless microphones.
Installation This section discusses how to install the XTRA Series of full rack power amplifiers. WARNING: Installation and service must be performed by authorized personnel only (see “UL Rack Mounting Guidelines)”. Application Examples The following illustrations are application examples for the XPA 2002, XPA 2002-70V, XPA 2003C-70V, and XPA 2004. Application examples for the XPA 2002-100V and XPA 2003C-100V are very similar to the XPA 2002-70V and XPA 2003C-70V examples, respectively.

Operation This section discusses how to operate the XPA power amplifiers.
a b Power indicator LED — This LED lights: zz Green when the amplifier is receiving full power. zz Amber when the amplifier is in Standby mode. Standby mode turns off all outputs from the amplifier, although the amplifier is still receiving power (see d of “Rear Panel Features and Operation).” Over Temp indicator LED — This LED lights red when the amplifier exceeds the recommended operating temperature for optimal lifetime. The LED turns off after the amplifier has cooled down sufficiently.

g Level adjustment (channels 1, 2, 3 and 4) — Use a Tweeker or small screwdriver to LEVEL adjust the audio input level for the corresponding channel. The analog potentiometers control the level from = (full attenuation) to 0 dB (no attenuation). 14 1 2 3 4 12 10 8 12 10 8 12 10 8 12 10 8 6 14 18 4 26 4 2 6 14 6 4 2 0 h 6 14 4 2 0 0 2 0 Balanced or unbalanced stereo/mono audio input connector — Wire the 3.5 mm 3-pin captive screw connectors for balanced or unbalanced input.
i High pass filter toggle switch — Use a small screwdriver to toggle this recessed two-position toggle switch that alternates between Off (no filtering) and 80 Hz. The XPA 2002-70V and XPA 2002-100V have 2 switches, one for each output channel. The XPA 2003C-70V and XPA 2003C-100V have one switch for the line distribution output channel (channel 3). Setting the switch to 80 Hz prevents the saturation of the speaker input transformers by low frequency signals.
Step 1: Strip and insert the speaker wires into the connector and tighten the captive screws. Be sure to observe correct polarity. Do not tin the wires! Step 2: Insert the wired connector into the amplifier output and secure the locking screws on either side. UT TP OU70V k Stereo audio output connector — Wire the included 4-pole, 5 mm screw lock captive screw connector to output 2-channel (XPA 2002, XPA 2003C-70V, and XPA 2003C-100V) or 4-channel (XPA 2004) audio.
Step 1: Strip and insert the speaker wires into the connector and tighten the captive screws. Be sure to observe the correct polarity. Do not tin the wires! Step 2: Insert the wired connector into the amplifier output and secure the locking screws on either side. UT TP 2 OU 1 l Bridged output mode (XPA 2002 and XPA 2004) — The output power of the XPA 2002 can be effectively doubled by using input channel 1 and bridging the outputs.
Bridged Mode Output XPA 2002 bridged mono output speaker wiring In bridged mode, the output mode toggle switches for Input 1 (A) or Input 3 (B) or both must be set to the bridged (up) position, as shown below. For Input 1: The channel 1 “+” output terminal becomes the bridged:”+” output terminal and the channel 2 “+” output terminal becomes the bridged “-” output terminal, as shown below.
XPA 2004 bridged mono output speaker wiring In bridged mode, the output mode toggle switches for Input 1 (A) or Input 3 (B) or both must be set to the bridged (up) position, as shown below. For Input 1: The channel 1 “+” output terminal becomes the bridged:”+” output terminal and the channel 2 “+” output terminal becomes the bridged “-” output terminal, as shown below.
On the input end, only Input 1 or Input 3 or both is used in bridged mode, as shown below.
