POWER PER CHANNEL:
•
1 X 500W into 4 ohm
•
1 X 850W into 2 ohm
•
1 X 500W into 1 ohm
•
Two amplifiers can be Bridged 1 X 1700W into 4 Ohm
•
Two amplifiers can be Bridged 1 X 1000W into 2 Ohm
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 24 dB per octave crossover can be adjusted so this amplifier can function as:
1.
Full range
2.
Low Pass for a subwoofer.
3.
Band Pass for a subwoofer or midbass of a 3 way speaker.
4.
High Pass for a midbass, midrange or tweeter.
•
The amplifier can be used full range with switch in HP position and frequency set to 10 Hz.
HP is always on so it can be used as a subsonic filter.
HP X1 frequency range is 10 Hz to 400 Hz.
HP X10 frequency range is 100 Hz to 4000 Hz.
LP: Adjustment range is 30 Hz to 350 Hz.
Band Pass with switch in LP position and adjusting both HP and LP to desired frequency.
•
The remote volume control is always active.
There is a clip distortion light on the remote volume control.
If you see this light on, reduce volume until the light goes out 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.
•
40 Hz EQ is adjustable between 0dB and +6dB.
Measure the subwoofer frequency response and adjust EQ to get the smoothest frequency response.
Avoid excess EQ boost because this will make the subwoofer sound "muddy" and cause the amplifier have clip
distortion prematurely.
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
