  • Page 9: Introduction

    The DD12 can be used as a main PA speaker, either stand-alone or as part of a larger system employing other Martin Audio system components. Its cabinet design also makes it ideal for use as a wedge monitor.

  • Page 10: Overview

    USER GUIDE OVERVIEW The DD12 is an active full-range loudspeaker with a 12” bass driver and a 1” HF driver, driven by an integral, specifically-designed, two-channel amplifier with comprehensive DSP. High power Class D, high efficiency amplifier channels are employed, incorporating individual comprehensive digital signal processing.
  • Page 11 DD12 USER GUIDE The two versions of the DD12 can be distinguished by the visibility of the IP24 Marking. Below is a photograph of the standard non-IP rated DD12, which has a Bezel trim (shown above) on the amplifier panel. This bezel covers the IP24 rating plate, thereby confirming that it is not IP-compliant.
  • Page 12 With the optional weatherproof cowl fitted (Martin Audio Part. No. ASF15019), the DD12’s IP24 rating plate is visible. Provided that the DD12 is used in portrait mode (i.e., upright), with the cowl, the weatherproof front grille (Martin Audio Part No. HAG01145) and Martin Audio Mains Cable sets fitted with IP65-rated Neutrik®...

    REAR CONNECTION PANEL MAINS INLET The DD12 mains inlet is located on the rear of the cabinet and is a Neutrik® PowerCON TRUE1 Male receptacle, single phase, IP65 rated inlet connector. A mating IP65 PowerCON TRUE1 plug (without lead) is supplied as standard with the DD12. A comprehensive mains cabling solution with C Form IP-rated input connectors is available for the DD12, which includes IP65- rated female outlets.

  • Page 16: Signal, U-Net And Indicators

    Two 8-pin rugged latching push-pull style data connectors are provided for the U-Net network connection. Two ports are available so that the network connections can be daisy-chained between further DD12 cabinets (or other U-Net equipped Martin Audio cabinets), or U-Net equipped devices such as Martin Merlin system controllers when designing larger speaker systems.

    (Part No. ASF14103). This is a self-contained, physically small unit which can be attached with Velcro or similar to the DD12. It connects to the DD12 with a standard USB cable, and back to the laptop running Vu-Net via Ethernet.

    FOH-to-stage runs. GETTING STARTED Before deploying the DD12, decide on the method of rigging to be used; please see “Rigging” on page 19 for details of rigging options. If the cabinet is to be ground stacked or pole-mounted it can be rigged completely before connections are made.

    90°, and re-attached. This will ensure that the cabinet’s design dispersion characteristics are retained. Important: the IP rating of the IP24-rated version of the DD12 is only valid when it is used in vertical orientation. The DD12 should not be used in outdoor or other inclement environments either in horizontal orientation, or as a floor monitor.
  • Page 20 (note the icons): The DD12’s cabinet has been designed to make it usable as a monitor wedge when used in landscape mode. When deployed as a floor monitor, the DD12 horn should be rotated so that the “wedge”...

  • Page 21: Rotating The Horn

    POLE MOUNTING: The DD12 is fitted with a standard top hat insert in the bottom of the cabinet allowing it to be mounted directly (in “portrait” orientation) onto a standard pole mount. No tilt adjustment is possible with this simplest mounting option.

  • Page 22: Accessories

    UNIVERSAL BRACKET The ASF20046 Universal Bracket allows the DD12 to be mounted in a number of ways. It can be fitted to with the top, bottom or side of the cabinet, and offers a single 13 mm (1/2”) fixing point which can be used to secure the cabinet to any standard 35 mm speaker stand using a pole mount adaptor (Part No.

  • Page 23: Fitting The Bracket

    When fitted with a scaffold clamp - either a standard half-coupler or trigger clamp (as shown) - the DD12 can be mounted either way up in portrait orientation, or in landscape orientation; the bracket allows the tilt to be adjusted in either case.
  • Page 24 M8 inserts, which are too short, and are not rated for use with flown systems. A flown DD12 using these screws to fix the bracket will NOT be safe. The bracket may be fixed to the cabinet in a number of different positions, on the top, bottom or side (relative to portrait orientation).
  • Page 25 It is easier to fit a pole mount adaptor or scaffold clamp to the Universal Bracket before attaching it to the cabinet. Once this is complete, place the bracket in position and screw into place using the M8 x 35 mm screws supplied with the bracket. Ensure these are fully tightened. DD12 User Guide V1.0...

  • Page 26: Yoke

    USER GUIDE YOKE The DD12 Yoke (Part No. ASF20047 provides an alternative option for mounting. It is most suitable for fixed installations but can also be used in portable applications. It can be used to mount the speaker to a wall or ceiling. Horizontal adjustment is available in portrait orientation and vertical adjustment in landscape orientation.
  • Page 27 For portable situations, attach the scaffold clamp or pole mount adaptor to the yoke before attaching the yoke to the cabinet. With the DD12 in portrait orientation, remove the existing M8 bolt from the centre position on the top of the cabinet.
  • Page 28 Screw into the cabinet insert. Tighten the fixing sufficiently to make it safe but allowing any fine adjustment if required. Finally, replace the M8 x 70 mm bolt in the yoke upper arm to secure it and tighten. DD12 User Guide V1.0...

    Further storage space is provided for tools, tape or additional rigging hardware. TRANSIT COVER A tough canvas transit cover is available for the DD12. This drops over the top and has cut-outs to suit the handle contours on either side. It protects the cabinet while allowing easy transportation.

    Vu-Net is Martin Audio’s monitoring and control application. It may be used with the DD12, either stand-alone or in conjunction with other Martin Audio network-ready products such as MLA, MLA Compact, MLA Mini and PSX.
