2-5: LOW CUT FILTER
The low-cut filter removes ultra-low frequencies from the audio signal. Most amplifier power is consumed by low
frequencies and most speaker woofer damage is caused by them. Activating this switch ensures that more power
can go to the middle frequencies and there is less chance for audio clipping.
3-4: 50HZ/30HZ roll off
If low cut filtering is activated, then the roll off frequency should be determined. At 30Hz, all audio below 30Hz will
be removed, at 50Hz more audio will be removed because all audio below 50Hz will be removed.
18. Stereo/Bridge Mode Switch- Bridged mono operation is easily achieved and gives you the output power of both
channels with just one mono output. For successful bridge operation, follow these instructions:
• Set the Mode Selector to Bridge while amplifier is off.
• Connect input signals.
• Use only the middle terminal post outputs for speaker wiring, or middle speakon output. Connect the speaker
load to the red terminals of each channel. Please confirm the (+) terminal of speaker to Channel A and the (-)
terminal of speaker to Channel B. Do not use the black terminals of each channel.
• The minimum load impedance in bridge mode is 4 Ohm.
• To adjust level, use Channel A control and leave Channel B level at zero.
• To use a subwoofer, make all setting adjustments on Channel A.
