13 & 16. Input Sensitivity Controller
The input sensitivity controller (gain) is used to properly match input signal levels
from the signal source to optimize the amplifier outputs. THIS IS NOT A VOLUME
CONTROL! To properly set, the maximum unclipped output from the radio or source
must be known using either an oscilloscope or, at minimum, a multi-meter and test
program. The amplifier can then be properly set to maximize output. If the gain is
not set properly the amplifier may clip early and damage your speakers and the
amplifier itself. It is highly recommended to use an audio specialist to properly adjust.
Independent gain controls are available for Group A and Group B channels.
14 & 17. Crossover Filter Selector
Select between Full (full range), LP (lowpass) and HP (highpass) depending on the
requirements of the speakers in your system. Selecting LP or HP turns on a 12dB
filter that can be adjusted using the Filter Frequency. This is selected independently for
Group A and Group B channels.
15 & 18. Crossover Frequency Controller
Use this feature to adjust the frequency of the crossover filter between 40 and 400Hz.
This is controlled independently for Group A and Group B channels.
