2 > PRINT GUIDES UNPACKING Each Martin MX5 controller is built to the highest standard and thoroughly inspected before it leaves the factory. After unpacking the unit, examine it carefully for any signs of transit damage and inform your dealer if any such damage is found. It is suggested that you retain the original packaging so that the unit can be repacked at a future date if necessary.
< 3.1 > PRINT GUIDES MECHANICAL The MX5 is housed in an all steel 1U 19" rack case. In permanent installations, the MX5 should be rack mounted using the four holes in the front panel. Additional support may be required for heavy duty road use. IMPORTANT: THE MAINS LEAD SUPPLIED MUST BE CONNECTED AS BELOW: GREEN/YELLOW BLUE BROWN - EARTH NEUTRAL LIVE Mains voltage tolerance ± 10% on each setting.
4 > PRINT GUIDES CONNECTIONS Power is supplied to the unit via an IEC connector with integral fuse holder/voltage selector. To change to a different mains voltage remove the rectangular fuse cap, rotate and replace so that the correct voltage is indicated by the arrow on the body of the receptacle. The earth terminal on the IEC connector is permanently connected to the chassis. The electronic reference 0V is taken to chassis via the rear panel signal ground switch.
< > PRINT GUIDES Always use 2-core + screen ‘balanced’ type signal leads, even for unbalanced circuits. The screen should be regarded as separate from the signal return, even if they are connected together at one end of the line. For either balanced or unbalanced operation, always connect the signal between Pins 2 and 3.
< 4.2 > PRINT GUIDES Output Connections The MX5 outputs are electronically balanced auto compensating via male XLR type connectors. Pin 1 is the (ground) connection and the signal appears between Pins 2 and 3. Always use 2-core + screen ‘balanced’ type signal leads, even for unbalanced circuits. The screen should be regarded as separate from the signal return, even if they are connected together at one end of the line.
> PRINT 5 CONTROLS 5.1 Mode Switch GUIDES This is mounted internally on the plug-in board and allows the unit when appropriate, to be switched from 3-way to 4-way operation. In 3-way mode the (‘mid’) output will function up to the upper bandpass filter or as defined by system parameters, band 4 (’high’) remains available and may be used for driving additional VHF units in ‘overlap’ mode. 5.
< > PRINT GUIDES WARNING: Care should be taken to avoid amplifier clipping. It is important to understand that a low power amplifier driven into clipping is more likely to damage a loudspeaker than a higher power amplifier used within its ratings. This is because music signals have a high peak to average "crest" factor. When an amplifier is severely overdriven, its output waveform is clipped (its peaks are squared off) – reducing the crest factor.
> 6 PRINT ENGLISH < CONTENTS GUIDES SYSTEM CONFIGURATION The MX5 where used in conjunction with a plug-in board becomes a dedicated system controller. Depending on the plug-in system-specific board, the MX5 is automatically configured either as a stereo 2-way or mono 3/4 way controller. Each plug-in board dictates a system-specific crossover function, equalisation and, in some cases, group delay.
