Frequently Asked Questions - Pro 7200 CREST AUDIO
How do I connect speakers to the Crest Audio Pro 7200?
Use SpeakON or binding post outputs. Ensure the impedance matches the amplifier's rated load (4 or 8 ohms). For bridge mode, connect the positive terminal of the speaker to the positive of channel A and negative to the positive of channel B.
Can I use the Pro 7200 in bridge mode for a subwoofer?
Yes, the Pro 7200 supports bridge mode, delivering up to 800W at 8 ohms. Set the rear switch to 'Bridge' and connect the subwoofer accordingly. Ensure the subwoofer can handle that power.
What is the input sensitivity setting for?
It allows matching the amplifier to different source levels. Use 0.775V for standard pro audio signals or 1.4V for higher output sources. Set it to the position that achieves maximum output without clipping.
How do I prevent overheating?
Ensure at least 1U of space above and below the unit in a rack. Keep front air intakes and rear exhaust clear of obstructions. The variable speed fan adjusts automatically, but if the thermal protection triggers, reduce volume or improve ventilation.
What should I do if the amplifier goes into protection mode?
Check for shorted speaker cables, improper impedance, or overheating. Turn off the unit, disconnect all loads, and let it cool. If the problem persists, inspect internal fuses or contact a qualified technician.
Can I use unbalanced inputs?
Yes, use 1/4'' TS cables on the TRS inputs. For best noise rejection, keep cable runs short and avoid running audio cables near power cables.
How to clean the Pro 7200?
Disconnect power. Wipe the front panel and chassis with a soft, dry cloth. Do not use any liquids, solvents, or abrasives. For the fan grilles, use compressed air.
What is the maximum current draw?
At full power, the unit draws up to 800W. On a 120V circuit, that's about 6.7A. Use a dedicated 15A circuit for safety.
Does the Pro 7200 have a ground lift switch?
Yes, a rear panel ground lift switch helps eliminate ground loop hum. If you hear a buzz, try both positions to see which yields lower noise.
Can I daisy-chain multiple Pro 7200 units?
Yes, the balanced XLR inputs include a parallel output for daisy-chaining to another amplifier. Use high-quality XLR cables to maintain signal integrity.
