CONNECTIONS
& CONTROLS
– 7 –
REMOTE GAIN CONTROL JACK - For connecting the remote gain control (included). This allows you to adjust the
gain while seated in the vehicle with the system operating.
LOW PASS CROSSOVER CONTROL - This control sets the upper frequency limit of the amplifier. For most
subwoofers a value just below 100 Hz is usually best.
SLOPE SWITCH - This allows you to switch between 12 dB and 24 dB per octave roll-off.
GAIN CONTROL - The gain control allows for a range of 0.3 - 8 Volts input. This means that if the setting is 0.3V, it
only takes 0.3V to drive the amp to full output. (Such a low setting allows for the amp to be easily overdriven, and
more susceptible to noise so a mid-position is highly recommended for most radios.)
LINE LEVEL INPUTS & OUTPUTS - The most commonly used inputs and outputs in the aftermarket are RCA type
line level. These can handle up to about 6 Volts rms without overdriving the amp. Such high voltages are rarely
found from car audio head units, so this is a very comfortable value. But should you need to drive the amp directly
from speaker level leads, use the supplied “High Level Adapter” to connect to the amp.
