    EN55103-2:1996 Electrical Safety EN60065:1998 INTRODUCTION Thank you for purchasing a Martin Audio WX3A System Controller. The WX3A is used to optimise the performance of Wavefront Series loudspeakers. Crossover functions, relative output levels and phase adjustments are all preset for a given Wavefront system by means of a dedicated system- specific plug-in board.

  • Page 3: Mains Connection

    MAINS CONNECTION The WX3A is provided with an IEC 320 type mains receptacle. It is supplied with a 2m mains lead terminated with a standard IEC 320 plug, which must be connected as below:...

  • Page 4: Connections

    CONNECTIONS Input Connections WX3A inputs are on female XLR type connectors and are electronically balanced. Pin 1 is normally open circuit but may be linked to sig 0V or chassis earth by inserting a link on the PCB (see Fig 1). The signal is always applied between Pin 2 (hot +) and Pin 3 (cold -).

  • Page 5: Output Connections

    For unbalanced use, having decided which pin is ‘hot’, connect the ‘cold’ pin and (Pin 1) together. The internal signal ground lead should be placed in the earth off position at the WX3A outputs which allows the amplifier to be locally grounded (as required for safety reasons) without causing a hum loop.

  • Page 6: Initial Settings

    System specific WX3A SYSTEM CONFIGURATIONS WITH PLUG-IN BOARDS The WX3A used in conjunction with a plug-in board becomes a dedicated system controller. Depending on the plug-in system-specific board, the WX3A is automatically configured either as a stereo 2-way or mono 3-way device for a specific Wavefront system.

  • Page 7: Wx3A / W2 - Active W2 Configuration (Stereo)

    LF EQ are outlined in the following. These should be examined carefully, especially when using sub-bass in a system. WX3A / W2 - Active W2 Configuration (Stereo) The WX3AW2LF board is used to control the W2 when operated as an active 2-way system (see Fig 4).
  • Page 8 W3 when operating either as stand-alone full-range systems or with additional WS2 sub-bass enclosures. It is also used to provide the outputs for other WX3A controllers configured to drive active W2 and W3 systems used in stereo with WS2 sub-bass enclosures.

  • Page 9: W1, W2, W3 Passive Operation Using Wx3Asf Card (Stereo)

    Using WX3ASF (Stereo) The WX3ASF may also be used to drive a sub-bass system to augment the W1, W2 and passive W3 systems (see Fig 8). The WX3A is normally operated in 100Hz high-pass/crossover Mode (2) (see Section 6.3) for this configuration, although it may be operated in Overlap Mode (3) if overlap is required for flown systems.

  • Page 10: Mono Sub Bass

    1 & 3 should be switched out. This is achieved by moving jumper links J1 – J2 on the card from the IN position to the OUT position (see Fig 9A) Fig 9A. L . F . EQ L . F . EQ Martin Audio – WX3A System Controller...
  • Page 11 PRINT GUIDES The limiters on the high-pass outputs of the WX3A driving the W2’s or W3’s should also be defeated to prevent them operating in advance of following units. To defeat the limiters on Bands 2 & 4, move jumper links J2 and J4 on the main circuit board to the left position.

  • Page 12: Wx3A W2 Mono With Sub Bass Configuration

    CONTENTS PRINT GUIDES WX3A W2 Mono With Sub Bass Configuration The W2 Active + Sub mono configuration is used to control a single channel active W2 system when used with a sub-bass (see Fig 11). Active crossover frequencies (100Hz, 1500Hz), relative output levels, driver alignment and equalisation are all pre-set for the W2 system plus sub-bass.

  • Page 13: Levels

    It should be noted, therefore, that front panel calibration would not necessarily indicate absolute band gains within the WX3A. When setting up a system for the first time, the WX3A band levels should be adjusted for desired balance and the settings noted for future reference.

  • Page 14: Important Note

    LEFT IMPORTANT NOTE If another WX3A is to be driven from any of the outputs - for instance when a WX3ASF provides the high-pass outputs for a WX3A configured for an active W2 or W3 - the limiters should be defeated on those outputs to prevent them from operating in advance of the limiters in the following units (see Fig 9).
