Philips SQ40 and SQ45 power amplifiers
In addition, a range of Power amplifiers (see SQ40 and SQ45 power amplifiers) feed the loudspeakers located in geographical and/or functional zones where people must be reached with background music, announcements, pre-recorded messages and alarm signals.

The SM30 system is designed to handle calls and music simultaneously by using a two-channel amplifiers system. When a call is made to a particular zone or combination of zones, music playing remaining zones will not be interrupted.

A system of priorities has been developed to cope with conflict situations. For example, when a person attempts to make a call when another call is being made by someone with a higher priority, the new call will not be switched through.

Choice of inputs

The SM30 system can be fed by input signals from call stations, microphones, music sources and a built-in prerecorded messages card.

The routing of an input signal is started by pushing a Numeric Keypad key or Function Key on a Call Station, closing a built-in microphone switch or closing a contact of a remote detector device.

Maximum configuration
A maximum configuration of the SM30 system contains up to six Call Stations and a maximum of 18 loudspeaker zones, or 3 Call Stations and up to 36 loudspeaker zones to be selected individually.
The SM30 was designed for medium-large sized public address applications and many legacy systems are currently installed in public spaces like government buildings, recreational areas and ships.
