User manual PEAVEY COMBO 300

[. . . ] This shape also greatly reduces the build-up of standing waves on the inside of the enclosure. This ensures a minimum of mid-bass and mid-range coloration of the reproduced sound due to the cabinet. The COMBO 300 is constructed of 3/4" plywood and is covered with Peavey's durable black carpet. [. . . ] The COMBO 300 is constructed of 3/4" plywood and is covered with Peavey's durable black carpet. Polymer corners are also a part of the unit to provide added protection to the enclosure. A powder-coated, expanded metal grille covers the lower part of the front of the enclosure to protect the mid- and low-frequency drivers from unforeseen accidents. Sound Guard, Peavey's proprietary circuit for high-frequency driver protection, has been included as a integral part of the crossover for the COMBO 300. The input signal is routed through the Sound Guard circuit in both full-range and bi-amp modes of operation. When the highfrequency drive level to the COMBO 300 exceeds a predetermined threshold, the Sound Guard circuit is engaged. This subtly decreases the signal going to the 22XT so that it will not be damaged due to long-term overpowering. Short duration transients will not be attenuated by Sound Guard and have the possibility to damage the 22XT. This strenuous test signal assures the user that every portion of this system can withstand today's high-technology music. The test signal contains large amounts of very low-frequency energy, effectively simulating the frequency content of live music situations. The full measure of high frequencies in the test signal allow for exposure of the speaker system to synthesized tones that may extend beyond audibility. This rating is contingent on having a minimum of 3 dB of amplifier headroom available so as to ensure that clipping does not occur. ARCHITECTURAL & ENGINEERING SPECIFICATIONS The loudspeaker system shall have an operating bandwidth of 54 Hz to 17 kHz. The nominal output level shall be 99 dB when measured at a distance of one meter with an input of one watt. The maximum continuous power handling shall be 350 watts, maximum program power of 700 watts and a peak power input of at least 1, 400 watts, with minimum amplifier headroom of 3 dB. The nominal radiation geometry shall be 96 degrees in the horizontal plane and 95 degrees in the vertical plane.
