CROSSOvER SETTINGS
7. Modify 3 different Crossover parameters: L GAIN, R GAIN, and Fc (cut-off Fre-
quency). Use the u or t buttons to choose the parameter to modify. Use the q or p
buttons to change the parameter.
Change Parameter
a) L GAIN and R GAIN are adjustable from -15 dB to +15 dB using the q or p but-
tons.
This adjustment changes the LEVEL in 1 dB steps. The range for this parameter
remains the same for ALL Channels in ALL modes.
b) The Fc adjustment depends on the output mode. The q or p buttons select the
frequency.
The frequency range of FRONT 2 changes based on the FRONT 1 configuration.
Once FRONT 1 is activated (Fc selected), FRONT 2 changes from a High-pass
crossover to a Band-pass crossover. This is to accomodate the 2-way output mode.
The Fc changes as follows:
