(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. See the chart below to determine the fuse value. -
Page 9: Level Setting (Reference414S)
.( INSTALLATION 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. -
Page 10: Crossover Adjustments
/ 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. The high and low pass portions of the crossover can be set independently of one another. In most car audio installations, there is a tendency for a “midbass boom.”... -
