POWER PER CHANNEL
•
1 x 1200 wRMS @ 4ohms
•
1 x 2000 wRMS @ 2ohms
•
1 x 4000 wRMS (Two FDP 1.2000s Bridged @ 4 ohms)
•
1 x 2400 wRMS (Two FDP 1.2000s Bridged @ 8 ohms)
•
Note: FDP 1.2000 is not 1 ohm stable, and cannot be bridged at 2 ohms
INPUT/OUTPUT CONFIGURATIONS
Because this is a one channel amplifier, if both left and right inputs are used, they are mixed to mono, which is useful
for subwoofers.
CROSSOVER CONFIGURATION
The 48 dB per octave
HP
and 24 dB per octave
LP
filters are always on so that they function as a Band Pass for a
subwoofer, or a midbass in a 3-way speaker. If you use a DSP or external crossover, set HP to 8Hz and LP to 350 Hz.
•
HP
frequency adjustment range is 8 Hz to 53 Hz, can use as a subsonic filter or crossover.
LP
frequency adjustment range is 40 Hz to 350 Hz.
•
The remote level control is always active.
There is a
PWR-PEAK
light on the remote level control.
If the light is red or flashing red, reduce volume until the light turns green so that you do not damage your
speaker.
•
PHASE
is continuously adjustable between 0 degrees and 180 degrees. Adjust by measuring frequency response
at the crossover frequency. Frequency response should be as smooth as possible.
SUBHARMONIC SYNTHESIZER - SHS
•
SHS
will add deeper bass to music that lacks it. Music is sampled and new tones one octave lower are
synthesized. The levels at 45Hz and 30Hz are set on the amplifier to music taste.
•
The remote must be plugged in for
SHS
to function. The
SHS
knob on the remote will adjust the amount of
synthesized level mixed with the music.
•
Avoid excess
SHS
level because this will make the subwoofer sound “muddy” and cause the amplifier to have
distortion prematurely.
•
There is a switch on the amplifier to turn
SHS
off.
AUTOMATIC POWER TURN ON/OFF
1.
The best way to automatically turn the amplifier power on and off is to use the REM wire from your source radio
connected to the REM amplifier terminal.
2.
If your original equipment stereo or source radio has a BTL amplifier, then the RCA inputs have an auto turn on
sensing circuit. When connecting high level BTL speaker wires to the RCA input, the REM wire is not necessary.
RCA INPUT, BOTH LOW LEVEL AND HIGH LEVEL
The amplifier
LEVEL
control has sufficient adjustment range for both low level and high level input into the RCA
jacks. A factory source radio that does not have RCA output, using the wires that are connected to the speakers, can be
directly connected to the RCA jacks when the amplifier
LEVEL
control is adjusted to 8V.
