Powered Speaker Systems A Closed System Architecture… There is much confusion these days in the world of powered speakers especially when it comes to defining “performance”. What constitutes “exceptional performance”? Is it wattage ratings, driver dimensions, cabinet dimensions, sound pressure levels, tone? It can get very confusing when you’re confronted with a barrage of specifications from manufacturers all claiming to have the “best performance”.

FEATURES 1. Selectable System EQ a. Normal and Boost (PRX710, PRX725, & PRX735 only) – When set in the “Normal” position, frequency response is linear and unaltered. When “Boost” is selected, internal equalization is applied to enhance low frequency and high frequency response. “Normal” will provide greater accuracy of reproduced music and higher speech intelligibility. “Boost” is particularly useful at lower levels to enhance the low and high frequencies of pre-recorded music.

FEATURES 1. POLARITY Button – This push button allows you to choose between 0° (Normal) or 180° (Inverse Polarity). The correct polarity setting will produce the best blend between the subwoofer and the full-range speaker and the strongest perceived bass response at the listening position. If the bass response seems weak, try inverting the polarity. 2.
TROUBLESHOOTING Symptom Likely Cause Speaker not connected to active AC power No sound No sound, speaker is connected to working AC power but won’t come on. No sound. Speaker comes on. No sound with microphone connected directly to the MIC input. Blown fuse Signal source (mixer, instrument, etc.) is not active Faulty cables and connections Microphone requires 48V phantom power Faulty microphone cable Verify that speaker is connected and that circuit is on.
Hum or Buzz that increases or decreases when the mixer level controls are moved Hum or Buzz Speakers feedback and howl when the microphone volume is turned up Too much low frequencies when playing back prerecorded music Improper A/C ground or faulty equipment connected to mixer input Disconnect or mute channels one at a time to isolate the problem. Refer to the owner’s manual of the faulty equipment for troubleshooting help.
