DESCRIPTION

The SP 3G is a full-range 3-way speaker system engineered for high performance and versatility. Useful for sound reinforcement, monitoring, public address and musical play- back. The system is comprised of a 15" Black Widow woofer with Kevlar-impregnated cone, a 6.5" professional mid-range driver, and a 22XT compression driver coupled with a CH 3 constant directivity horn.

This unit can be driven in a full- range or bi-amp mode by simply plugging into the desired jack on the input plate. The SP 3G has a trapezoidal shaped box, rather than a rectangular shaped box, that allows arrays to be constructed much more easily. 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 colora- tion of the reproduced sound due to the cabinet. The SP 3G is con- structed 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 propri- etary circuit for high-frequency driver protection, has been included as a integral part of the crossover for the SP 3G. The input signal is routed through the Sound Guard circuit in both full-range and bi-amp modes of operation. When the high- frequency drive level to the SP 3G 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 possibil- ity to damage the 22XT. The Sound Guard circuit is a dynamic circuit
