System Operation >>
The system has been designed to meet commonly requested public address facilities. The SM30 sound management system comprises a control centre, callstations and SQ45 power amplifiers.

A callstation including a high quality cardiod electret condenser microphone allows the operator to route and transmit calls. Up to 36 loudspeaker zones can be selected all together, with several zones combined, or individually by typing in the zone number.

The SM30 sound management system is intended for use with 2 separate channels. One channel will amplify the 'call' signal and the other one the 'music' signal. This allows the music to be transmitted without interruption, when a call is made to other loudspeaker zones. To fulfill the need of amplified power, more SQ45 power amplifiers can be installed.

SM30 Extension unit >>
The SM30 extension unit is intended to function as an amplifier surveillance unit with spare amplifier switching, as an audio monitoring facility and as a volume override relay supply unit. Two groups of 5 amplifiers can be connected: 4 amplifiers with 1 spare amplifier which will be surveilled. However, it is is possible to connect 8 amplifiers plus 1 spare amplifier.
