SETTING THE

HIGH PO WERlHiGH CURRENTS WlTCH

The High Power/High Current switch allows the REFERENCE amplifier to be one of two types of amps: either producing maximum power at higher impedances (perfect for satellites) or at lower impedances (usually with mukiple subwoofers). The circuit operates by selecting a sat of power supply voltage rails best suited to your particular application. One is a higher voltage “tap” optimized for high impedance applications while the other is lower voltage designed to provide more current. Unlike other amplifiers, Soundstream’s REFERENCE ampllfiers can be configured to drivevirtually any impedance and make maximum power!

COHERENTSTEREOTM/

MIXED-MONO /BRIDGED MONO

The REFERENCE amplifiers have the ability to operate in any one of the following modes:

ICoherent StereorM with identical lalt and right stereo channels for maximum fidelity. Best choice for satellite speakers. Use this mode unless Mixed-Mono is necessary.

Mixed-Monoin order to drive stereo and mono simultaneously: works well

for center channels. It can be used anytime you need a summed mono

Jchannel. Somewhat sacrifices sonic accuracy as additional circuitry is introduced to one channel. In hiked-Mono. the left channel Is Inveried, see diagmm below or on the bottom of the emplK?r.

Bridged MOnO for dedicated single channel operation; ideal far driving subwoofers. It is also used when large amounts of power are necessary for single speakers. In bridged mcno, only the r/ght channel Input Is actlve.

OTHER COMMENTS:

If you blow fuses with the REFERENCE amplifiers, switch to the High Currant mode. If the problem persists. it is likafy that the amplifier is seeing a dead short, either in the speaker wire or in the speaker itself. RecWy the problem

before blowing muId&%? fuses!

!, In bridged mono, on/y the right channel input is active.

NOTE: lfyou intend to drive a REFERENCE amp in Mono but have stereo outputs fmm your cmssover or source unit. you can put the swifch in Mixed-Mono buf follow lhs normal wiring for Bridged Mono.
