DESIGN FEATURES

Controls

1.Gain Adjuster – These can be adjusted to match output levels from a variety of source units individually for the left and right inputs.

2.Crossover Multiplier Range Switch – Used to set the multiplier for the left and right crossover frequencies between x1 and x10. A setting of x1 leaves the adjustable crossover frequency from 50-500Hz. A setting of x10 changes the adjustable crossover frequency to 500-5KHz (5000Hz)

3.Crossover Frequency Adjuster– Used to adjust the left and right crossover frequency. Variable from 50Hz to 500Hz in x1 mode, and 500-5KHz in x10 mode.

4.Crossover Type – Is used for selecting High-Pass Filter (HPF) or Low-Pass Filter (LPF) operation for the left and right speaker outputs.

5.Crossover Filter Switch – Off sets the crossover to all-pass, adjustments to the crossover range, freq, and type are bypassed. On allows adjustments to the crossover settings to be used.

6.Front End Defeat – Used to reroute the input signal around the signal processing circuitry within the amplifier. While in the ON position, all gain and crossover functions are bypassed.

7.Clipping LED Indicators – These Yellow LEDs illuminate if clipping is detected for either the left or right speaker outputs.

8.Power LED – This Green LED illuminates when the unit is turned on.

9.Protect LED – This Red LED illuminates if a short circuit or too low of an impedance is detected at the speaker connections or if the amplifier reaches thermal protection. The amplifier will automatically shut down if this occurs.
