Input Sensitivity Controller
These are used to properly match input levels with the source signal to optimize the
amplifier outputs. THEY ARE NOT A VOLUME CONTROL! To set properly, the
maximum unclipped output from the radio or source must be known using proper
test equipment. The input level adjustments can then be properly set to maximize
output without overdriving the amplifier. If the gain is not set properly the amplifier
may clip and damage your speakers and the amplifier itself. It is highly recommend-
ed to use an audio specialist to properly adjust.
Subsonic Filter Selector
Designed to be used with small subwoofers or vented enclosures with a high tuning
frequency, users can opt to select a 12dB subsonic filter (highpass crossover)
centered at either 25Hz or 35Hz.
Lowpass Frequency Controller
This amplifier is designed as strictly a subwoofer amplifier and therefore the crosso-
ver cannot be defeated. The crossover frequency controller allows the user to adjust
the frequency of the Lowpass crossover filter between 40 and 220Hz.
Bass Boost Controller
This allows the user to boost the output of the amplifier centered around 45Hz with a
range of 0 to +12dB.
