multi-cross™ crossover configuration
xover control 1/2- The crossover selection for channels 1 & 2 has three options:
When the switch is in the left position, the crossover section of the amplifier is
bypassed. Channels 1 & 2 output is full range.
When the switch is in the center position, channels 1 & 2 are filtered through a 12dB
per octave high-pass crossover that is infinitely variable from 45Hz to 5,000Hz.
When the switch is in the right position, channels 1 & 2 receive signal from the
crossover output of channels 3 & 4.
Note: When crossover 3/4 output is selected for channels 1/2, the 3/4 level
control adjusts the output level for channels 1/2 and 3/4 simultaneously.
xover control 3/4- The crossover sections dedicated for channels 3 & 4 are activated by depressing the
switch next to each frequency adjustment control. Both high-pass and low-pass crossovers are infinitely
adjustable from 45Hz to 5,000Hz. The high-pass and low-pass sections may be used individually or
together to create a bandpass filter.
Note: When using both sections to create a bandpass filter, make
sure you have selected a low-pass frequency that is higher than the
high-pass frequency!
xover control 5/6- The crossover selection for channels 5 & 6 has three options:
When the switch is in the left position, the crossover section of the amplifier is bypassed.
Channels 5 & 6 output is full range.
When the switch is in the center position, channels 5 & 6 are filtered through a 12dB
per octave low-pass crossover that is infinitely variable from 45Hz to 5,000Hz.
When the switch is in the right position, channels 5 & 6 receive signal from the crossover
output of channels 3 & 4.
Note: When crossover 3/4 output is selected for channels 5/6, the 3/4 level
control adjusts the output level for channels 3/4 and 5/6 simultaneously.
digital crossover frequency display
To facilitate quicker system tuning, we have incorporated
a digital display that shows the crossover frequency for
each crossover section, including the lowpass crossover
for the constant bass circuit. Push the select switch to
scroll through the different sections, and a blue led will
indicate which crossover is currently displayed.
