Pin 2 = In phase voltage (hot)
Pin 3 = Out-of-phase voltage (cold)

8 UNBALANCED INPUT

The RCA inlet permits the connection of a source of unbalanced signal. It is common to link the out-of-phase voltage
(Pin 3) to the ground (Pin 1). This connection is generally made on the wires.

The level rotative switch permits to adjust the level of the CMS loudspeaker. In position 0 (complete counterclockwise
rotation), the loudspeaker is in Standby. In position 1(complete counterclockwise rotation + 1 notch), the softening is
of –66dB. The last notch (complete clockwise rotation), corresponds to 0dB.
12 LED
The LED is red when the loudspeaker is in standby. The LED is green when the loudspeaker is activated.
13 CLIP INDICATOR
The clip indicator permits to control the audio signal quality. When the LED is lit up, the clip is activated. It means
that the signal is saturated and does not permit to work in good conditions. You must avoid activating the clip. To do
so, you must reduce the input signal level in the CMS loudspeaker and/or reduce the loudspeaker sound level 11.
