Panel Layout
(ENCORE-4.5K)
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)
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.
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 .
