7.5) SQ-1200, SQ-1600, SQ-2000, SQ2400 Switch Settings
Ground Lift:
Select if the signal ground is connected to the amplifier.
Sensitivity:
Select the input sensitivity.
Low Pass Filter:
100Hz 12dB/Oct if use Subwoofer without external crossover.
Input Mode:
Select between Mono (Parallel), Stereo and Bridge Mode.
Clip Mode:
Select if you connect 4
Ω
or 8
Ω speaker to your amplifier.
The two channel models offer the following control options by setting up the control switches.
Clip Mode:
To setup the internal clip limiter select the impedance of the speaker you are
connecting to the amplifier. Select 4 Ohm or 8 Ohm.
Ground Lift:
If nessary you can disconnect the signal ground from the amplifier. Select if the
ground of the signal will be connected or not.
Sensitivity Switches:
Select between three different input sensitivity level. (0,775V/1,0V/1,5V)
The right setting and a correct system gain structure is very important to reach maximum
signal headroom, less noise and avoid clipping at any position of your sound structure.
Please refer to 9.7 Setting System Gain Structure.
Low Pass Filter:
To use subwoofer without a seperate crossover or DSP processor your SQ amplifier
has a build in 100Hz/12dB low pass filter as a crossover for subwoofer.
Select LPF if you want to use subwoofer without external crossover.
Input Mode:
Select between Stereo, Mono (Parallel) or Bridge Mode.
If the switch is set to mono (parallel) mode the signal of the input socket CHA will be
