REMOTE
1) INPUT
Connect preamp signal cables from head unit to RCA input of the amplifiers.
A minimum level input of 0.2V is essential for correct operation.
2) GAIN (8V ~ 0.2V)
Matching the output voltage of the head unit's RCA line-outs to the input section.
3) SUBSONIC FILTER (10Hz ~ 60Hz @ 24dB OCTAVE SLOPE)
Control the high pass point for the speaker outputs to eliminate xtreme low frequencies.
4) LOW PASS FILTER (30Hz ~ 250Hz @ 24dB OCTAVE SLOPE)
Control the low pass point for the speaker outputs.
5) BASS BOOST
Variable bass boost with 0-12 dB @ 30Hz ~ 90Hz.
6) PHASE CONTROL
Variable phase adjustment from 0~180 degrees
7) REMOTE LEVEL CONTROL PORT
Connect external level control.
8) REMOTE CONTROL (OPTIONAL ITEM)
If you turn knob to clock-wise (MAX), it is maximum level position.
If you turn knob to counter clock-wise (MIN), it reduces level.
9) MASTER OUTPUT / SLAVE INPUT
For linkable connection of 2 same amplifiers. Minimum impedance is 2
In this mode, the master amplifier will control gain settings on the subsequent slaved amplifier.
10)
SPEAKER OUTPUTS
Amplifier connection to the loudspeakers. Minimum speaker cable is 12 gauge.
Minimum impedance for single unit is 1
Minimum impedance in linked connections is 2
11) POWER & PROTECTION INDICATOR
Power LED, green-lit or blue-lit shows correct operation. Protect LED, Red-lit shows general malfunction,
faulty connection or thermal protection.
