6 FIXING POINTS

The fixing points are made to ensure the link between the loudspeaker and a fixing support
(stand, wall fixing, ceiling fixing, ...). Please refer to page 11 to know the compatible fixations
(non-exhaustive list). The thread type is BSW 3/8".

7 BALANCED INPUT

The XLR inlet permits the connection of a source of symmetrical signal and follows standard
wiring instructions.
Pin 1 = ground (shielding)
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 asymmetrical 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.
9 ON/OFF Switch
The ON/OFF switch permits to put the internal amplifiers ON or OFF.
10 ON/STANDBY Switch
The ON/Standby switch permits to activate or to put the CMS loudspeaker in Mute. The LED is
green when the loudspeaker is activated. The LED is red when the loudspeaker is in Standby.

11 VOLUME

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.
