l o0.a AUTO HIGH CURRENTTM POWER SUPPLY The REFERENCE amplifier employs an extremely efficient Auto High CorrwP power supply (patent pending). This power supply circuitry automatically customizes your amplifier for optimum efficiency and power output into virtually any impedance load.
l l INSTALLATION STEP 2 b BALANCED/UNBALANCED INPUT The REFERENCE6445 amplifier has the ability to accept either standard Unbalanced RCA signal inputs, or Balanced “Pro Audio” inputs with the use of the Soundstream BLTTH or BLT4N Balanced Line Transmitters or some other balanced line audio source.
(Continued From page 13) INTERNAL The REFERENCE amplifiers are fused with automotive-type fuses. In the event of blown powersupplyfuses, the “FaulY’indicator on the top panel will light. The fuses are accessible via a plastic plug on the bottom of the amplifier.
.( INST ALLATION STEP 5 L LEVEL SETTING The input levels are adjusted by means of the individual channel input level controls located on the front of the amplifier. This is a unique dual-stage circuit that adjusts both level and gain. This topology maintains better Signal-to-Noise ratios even when using sources with minimal output.
l / INSTALLATION STEP 6 k CROSSOVER ADJUSTMENTS The REFERENCE644s and REFERENCE414s amplifiers incorporate an on- board staggered electronic crossover. They also have RCA outputs to drive an external amplifier. No external electronic crossover is necessary.
