Philips SM30 manual Remote Location Recording, Music Input Module, Mum, Music Source Inputs

The Function switch must be in its lowest (system) position for messages to be replayed through the system.

When the Function switch is in its top (record) or middle (monitor) position, SM30 will not be able to use the Recorded Message function, and the messages already recorded will not be accessible to the user. An ERROR warning will be seen on the display of the Control Centre, indicating that the Message Module is not in its ‘system’ mode.

If the Function switch is in the top (record) position, and the Message Selection switch is moved to a position where a message is already recorded, the green Message Present LED illuminates to warn that a message is present at that position.

Remote Location Recording

Because the Record and Monitor functions are independent of the SM30 microprocessor, the unit may be taken out of the Control Centre, and transported to a remote location.

There, with the aid of suitable power supplies of +5 V and +35 V, the module may be used to record the messages in a more suitable/convenient recording environment. Refer to the service documentation of SM30 how to make the connections.

11	MUSIC INPUT MODULE
	(MUM)	LBB 1286/10

The ability of SM30 to play music, which is uninterrupted, even though the system is handling a call routed to other loudspeaker zones, is an important feature of the system. To make best use of this feature, Philips have developed the Music Input Module. The module enables 3 independent music sources to be connected to the Control Centre.

11.1Installation

Mounting in the Control Centre

One Music Input Module may be installed in the Control Centre.

This module must be located in slot B as illustrated in fig.5.1.

Music Source Inputs

The module provides 3 sets of double cinch sockets (fig.11A) for connection of the music sources. The double sockets allow stereo signal sources to be connected, using standard double cinch/ cinch Hi-Fi cables. The stereo signal is mixed to mono in the module. A mono signal (e.g. from a radio tuner) should simply be plugged into either one of the two sockets.

11.2Adjustments

Individual Input Volume Controls Three potentiometers (fig.11B) corresponding to the three inputs, give the user/installer the capability of setting the input volume levels of each source independently.

Adjust the source signal levels so that when the operator selects a different source, no great change in music volume level occurs.
