MACRO range installation manual. Issue 6 Fig. 1 Location of Treble, Bass, and Master gain controls leaving the factory, the controls will be set for level response. See Fig. 1 A conventional master level control is featured on the mother PCB between the line driver module (TB.6 etc) and the pre-amplifier stabiliser module (PS.9 etc.) next to it. This control is set to maximum (fully clockwise) on leaving the factory. See Fig.

MACRO range installation manual. Issue 6 FACILITY USAGE or FUNCTION Audio gain Chime level VOX sensitivity Sets the level of amplification of incoming signal. Influenced by no other adjustment Determines the level of chime tone to be injected. Influenced by no other adjustment Sets level of audio input at which the VOX circuit is triggered. Influenced by Audio gain.
MACRO range installation manual. Issue 6 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 (nonpriority) mode.
MACRO range installation manual. Issue 6 Signal arrangements and DIN cable connections are shown in Fig. 4 As a factory fitted option, a line input transformer may be fitted. See page 21 for further details. Slave amplifiers have a fixed sensitivity and no input control is provided on standard models. The input impedance is approximately 10k ohms. Immediate technical advice for specific problems is available from the Technical Services Department, Mustang Communications Ltd.
MACRO range installation manual. Issue 6 Fig. 7 Interconnection of several amplifiers POWER AMPLIFIER MODULE The power output stage of the amplifier including all low level drive circuitry, and output devices are contained in a module which is bolted to the rear panel by four screws. The module is connected into circuit by push-on tab connectors facilitating easy change of a suspect module.

The cover may now be swung round.100V output The general concept of a 100V line loudspeaker system is that a quantity of 100V line loudspeakers are connected in parallel across the amplifier output terminals. The loudspeakers may be arranged in any order, any combination and if necessary, using any number of feeds from the amplifier.
MACRO range installation manual. Issue 6 AUXILIARY OUTPUT CONNECTION A standard 25 way D connector on the amplifier rear provides all the auxiliary connections associated with current sinking, alarms, auxiliary DC and signal outputs, etc., where applicable. The standard connections are as follows: 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 nc 21 nc 22 nc 23 24 25 250mA current sink activated by input module No.1 during priority access 250mA current sink activated by input module No.
MACRO range installation manual. Issue 6 COMBINING THE INPUT/OUTPUT FACILITIES OF TWO OR MORE UNITS This may be considered where one single amplifier cannot provide enough input facilities or output power for a particular application. Mixers may be combined with mixer amplifiers, and with slave amplifiers in any combination via their respective mixer facility sockets. Example M2508 and M250 to provide 8 inputs and 500 Watt output to two loudspeaker zones.

Issue 6 on the Power Management Board and will drop out as a result of :AC: DC: AC supply failure AC fuse failure AC supply disconnection Amplifier switched off Rectifier circuit failure DC supply fuse failure DC supply disconnection (even with charger operational) DC standby supply failure Amplifier switched off These relay contacts may be used to trigger remote audible or visual alarms within the system to draw attention to a possible problem.
MACRO range installation manual. Issue 6 Automatic level control - all units except slave amplifiers. Mustang product code TB/ALC The standard module fitted to a mixer or mixer-amplifier to provide line driver facilities is a TB.6 and is located second from the right when viewed from the front. This is replaced with a TB.6A to provide the Automatic level control facility (ALC) and it will enable the system to be set up such that a pre-settable amplitude cannot be exceeded.
MACRO range installation manual. Issue 6 The Locking DIN pin connections are:Pin 1 Pin 2 Pin 3 No connection out of phase audio in phase audio .775V RMS @ 10k ohms balanced (floating) It would normally be appropriate to interconnect two pieces of equipment using twin-screened cable. The braiding should be earthed to one unit only. If the decision is made to use the Mustang power amplifier for earthing, then the cable clamp of the DIN plug may be used for the purpose, without the likelihood of a hum loop.
MACRO range installation manual. Issue 6 A. DO NOT allow the cable braiding/shield to contact the cable clamp, plug body or fixing screw. An earth/hum loop will result. This topic is fully covered on page 20. B. Application of silicon grease to the cable outer sleeve will facilitate easy insertion into the grommet. C. Be careful when soldering. Avoid bridging adjacent pins of the locking DIN connectors with solder. If pins 4 and 5 are not to be used, break them off to provide extra space for soldering.
MACRO range installation manual. Issue 6 FUSES Fuses for the protection of both the AC and DC supplies are located on the rear panel. Certain fuses are contained within the chassis of MACRO equipment rather than on accessible front/rear panels: (A) (B) (C) F1A pre-amplifier DC fuse on the pre-amplifier stabiliser module F1A auxiliary DC fuse on the pre-amplifier stabiliser module Special fusible link on the power output module See APPENDIX D and APPENDIX E for identification.
MACRO range installation manual. Issue 6 FAULTS - SYMPTOMS AND CHECKLIST The following list of fault symptoms and check points cannot be considered as comprehensive, but as a guide to the most likely faults and causes. We assume that the input sources and loudspeakers are properly connected and in good working order. Be sure to check these carefully first before investigating the amplifier.
