Intr oduction About this Manual This manual contains information about the Extron XTRA Series of power amplifiers. • XP A 1002 two-channel stereo audio power amplifier • XP A 1002 Plus two-chann.
Extron patented CDRS — Class D ripple suppr ession — A patented, exclusive technology from Extr on that eliminates the high frequency switching ripple and EMI emissions found in typical Class D amplifiers. CDRS enables Extron power amplifiers to be situated near wireless A V devices without RF interference.
Installation This section discusses how to install the XTRA Series of audio power amplifiers. T opics that are cover ed, include: • Application Examples • Mounting the XTRA Series Amplifier W ARNING: Failure to follow these instructions may r esult in serious injury .

2. Reduced air flow — Installation of the equipment in a rack should be such that the amount of air flow requir ed for safe operation of the equipment is not compromised. 3. Mechanical loading — Mounting of the equipment in the rack should be such that a hazardous condition is not achieved due to uneven mechanical loading.
Rack Mounting V entilation 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 r ed whenever the recommended operating temperature has been exceeded (see Fr ont Panel Features and Operation on page 9).
The optional Flexible Conduit Adapter Kit consists of: • One EMT adapter plate • One 6-foot long electrical conduit • Three 7.5 feet, 18-gauge spade connector power wir es • One UL-rated zip t.
3. Remove the 2 screws holding the hot (Line) and neutral wir es from the terminal block on the PCB (see figure 6). 100-240V 1.3A 50-60Hz Remove sc re ws (both sides) to re lease IEC connector plate. Remove nut Blue Wi re Brown Wi re L N Figure 6. Removing the IEC Connector 4.
Operation This section discusses how to operate the XTRA Series of audio power amplifiers. T opics covered, include: • Front Panel Featur es and Operation • Rear Panel Features and Operation Fr o.
c Limiter/Protect indicator LEDs — These LEDs (r epresenting their r espective output channels) light red under thr ee circumstances: 12 LIMITER/PRO TECT • When the output wiring is shorted together . • When audio clipping occurs, the LED of the corresponding channel blinks once per clip occurrence.

d Attenuation — Use a small screwdriver to adjust the audio input level for the corresponding channel. The analog potentiometers contr ol the level from = (full attenuation) to 0 dB (no attenuation).

Doing so will short the outputs, damage the amplifier , or both. NOTE: The power output of the XP A 1002 series can be effectively doubled by bridging the output.
ç Mono audio output connector — W ire the included 2-pole, 5 mm scr ew lock captive screw connector for mono audio (see the steps below). Output is designed to power 70 V (XP A 2001-70V) or 100 V (XP A 2001-100V) line distribution systems and is rated at 200 watts.
h High pass filter (HPF) toggle switch (XP A 2001 series) — Use a small screwdriver to toggle this r ecessed 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.
Controlling Multiple Amplifiers with One V olume Controller Several XP A 1002 and XP A 2001 series units can be daisy-chained so that one volume controller can simultaneously r egulate the volume of all the amplifiers. NOTES: • As additional amplifiers are added to the daisy chain, the sensitivity of the volume potentiometer will change.
Bridged Mono Output The power output of the XP A 1002 and XP A 1002 Plus can be effectively doubled by bridging the output. Bridging allows power to be output in mono at 200 watts at 8 ohms. NOTES: • The bridging instructions that follow apply only to the XP A 1002 series.
T r oubleshooting The front and r ear panels have LED warning indicators, as described in the following diagnostic information. Amplifier Fails to Exit Standby Mode Promptly The input channel (channels 1 and 2) Signal LED lights green per indicated input channel when an input signal is detected.
