Priority/passive setting of modules

Certain modules contain features enabling the commissioning engineer to set them to operate as normal priority modules, or as passive modules. Referring to APPENDIX E, this is accomplished on the M24 microphone input module for example by transposing the position of a jumper link on the module, from lower middle (position B) to lower left (position A) for the change to passive (non- priority) mode. In this mode, the module audio signal path is permanently enabled, though it will be inhibited by access of any higher priority module and is itself rendered unable to inhibit any other module. The jumper link may be changed at any time, and is a simple push fit.

Priority memory

If, whilst a priority module is being accessed, an attempt is made to trigger a tone generator module which is installed in a lower priority level, and which features a priority memory, then no apparent action will result until the higher priority is released, at which time the memory circuit will automatically and immediately trigger the timer circuit of the module, causing it to operate in the normal manner for its pre-set duration.

PRE-ANNOUNCEMENT CHIMES - all units except slave amplifiers

The customary ding-dong chime signals which can often be heard to precede announcements in public buildings, are generated in MACRO range equipment by certain standard microphone or line input, and tone generator modules. It is possible therefore to install two or more such modules, and adjust them so as to be readily distinguishable. The chime is triggered only on successful access to the priority chain. See APPENDIX E for location of adjustments.

MIXER FACILITY CONNECTIONS - 0dB SIGNAL ACCESS POINT

This connection may be used to gain access to the output of the pre-amplifier section, or the input of the power amplifier section, at 0dBV level. Standard connection is by Locking 5 pin DIN panel socket with 180 degree pin spacing pattern. Connections are as follows:

Fig. 4 Mixer facility connections for standard locking DIN connector 0dB signal in/out access for mixers & mixer amplifiers -

The standard Locking DIN pin connections are as follows:- Pin 1 Pre master gain control direct from TB.6 module Pin 2 Signal earth (cable audio shield)

Pin 3 Post master gain control (via 10k source)

With the master control at position ì0î the loading effect exhibited by pin 3 is approximately 6k8 ohms. For further clarification of this arrangement see the block schematic diagram - APPENDIX A

Input connections for slave amplifier

The standard input circuit is suitable for unbalanced line operation, and the locking DIN signal input connections are:-

Pin 1 No connection

Pin 2 signal earth (cable braiding)

Pin 3 .775v @ 10k ohms power amplifier input
