4 > PRINT GUIDES MAINS CONNECTIONS The M3 is supplied with a captive mains lead with an integral U.K. BS1363 3 pin plug. Should the moulded plug be removed and another plug substituted the cable must be re-wired as below. GREEN/YELLOW - EARTH BROWN - LIVE BLUE - NEUTRAL WARNING: The M3 Controller must always be operated with the mains safety earth connected.
5 > PRINT GUIDES SIGNAL CONNECTIONS 5.1 Input connections M3 inputs are on female XLR-type connectors and are electronically balanced. Pin 1 is normally open circuit but may be linked to Ground (chassis earth) or Lift (signal 0V) by positioning jumper links on the main PCB (J1,J2). The signal is always applied between pin 2 (hot +) and pin 3 (cold -). Always use 2-core plus screen ‘balanced’ type signal cable, even for unbalanced circuits.
6 > PRINT GUIDES INITIAL SETTINGS M3 system controllers are supplied set up as follows: Mains Voltage - 220-240V Pin 1 (input) J1, J2 - OPEN CIRCUIT Pin 1 (outputs) J3, J4, J5, J6. - LIFT (0V) Mono Sum CH1/3 J17 - Disabled Position ‘A’ Limiters in/out J7, J8, J9, J10. - IN ABS Phase J15, J16 - Position ‘A’ Limiter threshold - 0.
7 > PRINT GUIDES M3 SYSTEM CONFIGURATIONS There are many different system combinations possible with the blackline series. Shown below are some typical configurations.

8 > PRINT GUIDES LEVELS The system-specific plug-in top cards provide the necessary channel gain or attenuation to provide approximate system balance when the level control is in the 0dB position. This assumes the use of amplifiers with identical gains. Plus and minus 3dB’s of gain or attenuation is available on outputs 1 and 3 to adjust the balance of the system with respect to channels 2 and 4 which have a nominal output level of 0dB.
< > PRINT GUIDES Each limiter may be completely defeated, by setting J7, J8, J9 and J10 to the out position. If another M3 is to be driven from any of the output channels (where one M3 splits the signal between sub-bass loudspeakers and the main system crossovers), then the limiters should be defeated on those channels to prevent them operating before the limiters in the following controller. The use of very high power amplifiers with outputs greater than those recommended is discouraged.
