The USA-5500x comes with an optional “Remote Bass Gain”
or “RBG” that can be mounted in the passenger compartment to
independently attenuate the low pass output.
The “BASS GAIN” located on the terminal endplate of
the unit is used both to set the level of the low pass
output and control the range of the RBG. It does
not matter which way the RBG cable is connected. Use a common
screwdriver tip or something like it to tighten the RBG knob.
The two-way crossover of the 5500x “splits” the full-range audio signal into high and low
frequencies. The highs are reproduced by four 75 watt channels that are 2 ohm stable. The low
frequencies are summed monaural and played by a single 250 watt channel that will produce
350 watts into 2 ohms. Independent frequency controls adjust the “roll-off” of the high and low
frequencies from 50Hz to 500Hz at 12 Db per octave.
The low frequency control limits the
high frequency response of the low
pass output, and the high frequency
control limits the low frequency
response of the high pass output.
