Intr oduction About this Manual This manual contains information about the Extron XTRA Series of power ampliers. • XP A 1002 two-channel stereo audio power amplifier • XP A 2001-70V mono audio.
Convection cooled — The XTRA Series of amplifiers are convection cooled without the need for fans, ensuring quiet, reliable operation. Ultra low inrush current - no need for power sequencing — Allows many XTRA Series amplifiers to be powered on simultaneously without overloading power cir cuits.
Installation This section discusses how to install the XTRA Series of audio power amplifiers. T opics that are covered, include: • Application Examples • Mounting the XP A 1002 and XP A 2001 WARNING: Failur e to follow these instructions may result in serious injury .

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 amplier . An over temp indicator LED on the front panel of the amplier lights r ed whenever the recommended operating temperature has been exceeded.
NOTE: If needed, Extron r ecommends using a UL-rated crimp tool to terminate the spade connectors. One recommended choice is the Molex crimp tool (Molex part #64001-0100). The kit provides a convenient means to r eplace the XP A ’ s IEC power cord with conduit, where r equired by local codes.

Operation This section discusses how to operate the XTRA Series of audio power amplifiers. T opics that are covered, include: • Front Panel Featur es and Operation • Rear Panel Features and Opera.
c Limiter/Protect indicator LEDs (channels 1 and 2) — These LEDs (r epresenting output channels 1 and 2) light red under thr ee circumstances: 12 LIMITER/PRO TECT • When the output wiring is shorted together • When audio clipping occurs, the corresponding channel’ s LED blinks once per clip occurrence.

d Attenuation (channels 1 and 2) — 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. NOTES: • On the XP A 2001, the single control adjusts the levels of both channels simultaneously prior to summing them together .
â Balanced or unbalanced stereo or mono audio input connector (XP A 2001) — Wire the 3.5 mm 5-pin captive screw connector for balanced or unbalanced input.
• Pin 5 connected to ground (pin 4) places the amplifier in standby mode. Standby mode turns off all output, although the amplier is still receiving power . Use the included 2-pin, 3.5 mm captive screw connector to r emotely ground pin 5. The power indicator LED lights amber when the amplier is in standby mode.
T o wire the stereo audio output connector: Step 1: Strip and insert the speaker wires into the connector and tighten the captive screws. Be sur e to observe the correct polarity . Do not tin the wires! Step 2: Insert the wired connector into the amplifier output and secur e the locking screws on either side.
T o wire the mono audio output connector: Step 1: Strip and insert the speaker wires into the connector and tighten the captive screws. Be sur e to observe the correct polarity . Do not tin the wires! Step 2: Insert the wired connector into the amplifier output and secur e the locking screws on either side.
Remote V olume Control Options for remote contr ol of the XP A ampliers include the Extron VCM 100 and VC 50 volume controllers. Thir d party 10k potentiometer volume controllers can also be connected to this port. As shown in the following illustration, pin V (1) on the XP A is a 10 VDC reference voltage.
Controlling Multiple Amplifiers with One V olume Controller Several XP A 1002 and XP A 2001 units can be daisy-chained so that one volume controller can simultaneously regulate the volume of all the amplifiers. NOTES: • As additional amplifiers ar e added to the daisy chain, the sensitivity of the volume potentiometer will change.
Bridged Mono Output The power output of the XP A 1002 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 model.
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.
Limiter/Protect LED W arning Indicators The output channel (channels 1 and 2) Limiter/Protect LED lights r ed per indicated output channel as shown in the following diagnostic information. LED State Problem Description Problem Solution Blinks Audio clipping is occurring at the rate of one blink per clip.
