MONOBLOCK DIGITAL INPUT & OUTPUT CONNECTION
RCA INPUTS
The RCA inputs ensure the highest quality contacts
and the lowest noise in your audio system.
POWER & PROTECT INDICATORS -
When the unit is powered on and operating
correctly the power LED illuminates.
When the unit is malfunctioning or in protect,
the protect LED will be on.
GAIN ( 6V - 0.2V )
This adjusts the normal operating level of
the amplifier by matching the level from
the headunit.
SUBWOOFER USE
Using your head units subwoofer crossover section,
or an inline active crossover, set the subwoofer
crossover to your desired frequency there and then
set the S1 amplifier to the FULL x-over setting and set
gain as needed. If using a full range signal from your
source, set S1 x-over setting to LPF and adjust LPF
gain pot to 80Hz.
HIGH PASS FILTER ( 20Hz - 5KHz )
Controls the high pass cutoff point for the speaker
outputs.
HPF can be selected with X-over switch located
next to it.
X-OVER ( HPF/ FULL /LPF )
At HPF, High pass filter is activated
At FULL, It is bypass.
At LPF, Low pass filter are activated.
LOW PASS FILTER ( 50Hz - FULL )
This allows you to tune the response of the amplifier
at higher bass frequencies to roll off for
a seamless integration into your midbass.
BASS BOOST ( 0 - 9dB )
This allows you to tune amplifier response with up
to 9dB of boost centered at 45Hz
REMOTE CONTROL
Use this to control level of the amplifier from
your driver’s seat.
GROUND ( GND ) & POWER ( +12V )
The power and ground will accommodate 4 guage
wire.
Use high quality pure copper wire only.
REMOTE ( REM )
REM connector will accept wire sizes from12 to 16
guage.
This terminal is used to remotely turn-on and turn-off
the amplifier when +12V DC is applied.
SPEAKER TERMINAL BLOCK
Connect speaker cables from speaker terminal block
to subwoofers.
Subwoofers impedance should be checked carefully.
S1 minimum impedance is 1ohm.
