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. 4. Circuit overload[...]

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). T o reduce the chances for an over tem[...]

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. NOTES: • Y ou must use Class 2 wiring for this output to comply with UL require[...]

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. Saturation can r esult in severe distortion of the speaker output signal. HPF 80 Hz [...]

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. The m[...]

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. • The minimum load impedance when bridging is 8 ohms. T o bridge the out[...]
