Peavey XR-500 Operating Manual

GENERAL DESCRIPTION
The new XR-500 represents our latest effort to combine professional features previously found only in separate mixer/equalizer/power
amp components into a single compact ar,o 'ugaea package. The design of the XR-500 utilizes ihe latest advances n semiconductor
technology and the overall circuitry has been designee: and optimized by use of the latest computer aided design techniques Tms unit's
Improved specifications nave been made posable by a thorough and complete cesicn effort resulting in ail new circuitry from the input jack
through lo the speaker output.
The XR-500 features five mdependenl input channels and includes a separate pfe" monitor ser\J acbve shelving type high and tow
equalization, and a "posl' effects sand on each chance! Master level contrc.'s arc provided for 'ho mao. rrcoilo' and reverb return \ lull
seven-bare graphic equalizer has been built into the system and utilizes Ihe most contemporary active filter circuitry available Additional
flexibility is provided by the XR-500's patch panel, enabling this versalile unit lo be usee in cxxiiunclian with an exlremey v/idu range o'
auxiliary equipment
The newly engineered 130-Walt power amplifier features our exclusive DD~^ {' Distortion Dotociion Techniquca") compression

available. Ihus maximizing every precious Watt of power available This compresscn feature alicv/s the XR-500 to quite eheclively compete
with un ts having conscerably more RMS power
The power amp of ihe XR-500 utilizes lour high-voltage, high-speed TO-3 powpr devices bolted to a massive heatsink The internal
power supply consists ol a very large pov/er (mains) transformer featuring a grain oriented silicon steel core and a high degree of magnetic
shielding to mmmizo extraneous hum fields Siiicor rectifiers cornectec in

ful wave pudge feed powe* to large elect'olytic Mter banks and
provide considerably more music pov/er than the 130-Watt RMS power rating would indicate
■Overall, ihe XR-500 brings protessima performance together m an exiremesy versatile and compact package, ofiering features and
specifications formerly available only with separate componerts in a single pccable package.
