SRX250.1V // SRX500.1V // SRX750.1V // SRX1200.1V
Gain
The gain control is NOT a volume control. The gain control adjusts the amount of signal required to drive the amplifier
to full output. With the gain at full clockwise rotation, less signal voltage is required to drive the amp to full output.
With the gain at full counter clockwise rotation, more signal voltage is required to drive the amp to full output. For
optimal performance, set the gain control to minimum.
Low Pass Filter
The lowpass crossover/filter is designed to remove high frequency information from a speaker. This is generally used
to prevent mid bass speakers or subwoofers from trying to reproduce mid and high frequency information that they
are not designed to reproduce. The crossover frequency is adjustable from 50Hz-250Hz and use a 12dB per octave
slope. To engage the LPF slide the switch to the position marked LPF. Frequency selection is made by rotating the dial:
Clockwise raises the frequency, counter clockwise lowers the frequency. Most subwoofers should be set between
80Hz and 100Hz depending on how low the mid-bass or midrange drivers are capable of playing.
Bass Boost
Bass boost is switchable to off (0dB) or +6dB and +12dB. Boost should be used with discretion. Electronically enhance
boost places an additional load on the amplifier and the speakers they are connected to.
Remote Level Control
The amplifiers have inputs for a remote level control (RLC). This will allow the amplifier input level to be adjusted from
the listening position. Connect the RJ45 jack on the front to the amplifier. Install the control module in front of the
vehicle in a location that is easily accessible to the driver.
Subsonic Filter
The subsonic filter utilizes an internal 12dB per octave slope and is variable from 15Hz-50Hz
