4.2 Active Mode
• In active mode, each S4-LCRMT and single or multiple S4-
LCR65W module employed for each channel is connected
separately to a power amplifier channel.
• The mode selection switches on the rear of each S4-LCR65W
module or modules should be switched to “BYP” (bypass).
Ensure that the mode selection switch position is correct
before use.
• The two mode selection jumpers on the crossover PCB of
each S4-LCR65W module should be located in the J2 position.
The mode selection jumpers can be accessed by lifting the
crossover PCB module from the back of the S4-LCR65W
module. This is achieved by removing the four screws identified
in Diagram 7.
• The power amplifier channel driving each S4-LCRMT and
S4-LCR65W modules must be driven via active filters. The
recommended filter characteristics are tabulated below.
Filter S4-LCR65W S4-LCRMT
Type Low pass High pass
Frequency 300 Hz 500 Hz
Slope 12 dB/octave 12 dB/octave
Q 0.71 1.0
Gain 0 dB (see note) 0 dB
Note: Where a S4-LCRMT module is used with a single S4-
LCR65W module ,the S4-LCR65W gain should be reduced by
-6 dB.
