DESIGN FEA
TURES
1. Gain Adjuster – These can be adjusted to match output levels from a variety of source units individually
for the front and rear 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 front and rear 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
front and rear 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 front or rear
channel outputs.
8. Power LED – This Green LED illuminates when the unit is turned on.
9. 2/4 Channel Switch – Pressing this switch in, switches the inputs to a 2-channel mode, allowing
connection to only the front inputs with a 4-channel output.
10. 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.
