20 0.77V | 1.4V | 26dB

The input sensitivity at which the amplifier is delivering its full rated power, can be

set with this switch between 0.775 V

RMS

 and 1.4 V

RMS

). Often multiple amplifiers are

used simultaneously. In this case, switch to the ‘26 dB’ position, the signal will then

be amplified by all amps equally. Thus, you can combine different power amps of

the S-series, and always get the same output level.

21 CH-1 (MONO)

Connect the line-level signals to be amplified to the XLR input of Channel 1 using a

XLR cable.

22 CH-1 (MONO)

Connect the line-level signals to be amplified to the 1/4" balanced TRS phone jack

input of Channel 1 using a 1/4" phone jack cable.

23 Power supply switch

Before connecting the amplifier to the mains power supply, ensure that the mains

voltage switch on the bottom side (or rear side for S-150) is in the position that cor‐

responds to the actual power available (in Germany 230 V~). f in doubt, consult an

electrician.
