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. The combination of built-in amplification and DSP
offers a high level of control in a compact, lightweight loudspeaker. With the aid of Vu-Net
network control software, outstanding levels of consistent, high quality audio can be delivered.
The DD12 is intended to be used either singly or in multiples as a stand-alone, plug-and-play
system, or as additional elements in larger systems. Optimised venue push button presets are
accessible via the rear panel.
The DD12 has audio inputs that can be either standard balanced analogue or AES/EBU digital.
(AES/EBU only available when running a system under Vu-Net control.) A parallel connection
is available to daisy-chain between cabinets. The DD12 features network control via a U-Net
interface, which carries all control data for the on-board DSP. U-Net connections are made via a
pair of very high quality, rugged 8-way push-pull latching connectors rated for high speed data
applications.
Mains connection is via a Neutrik® PowerCON TRUE1 connector.
Each channel of DSP comprises extensive processing optimised for the driver being controlled:
this includes delay, parametric EQ, high and low pass filters, IIR all-pass filters, FIR low pass
filter and EQ, gain, phase and limiting. In addition there are user-accessible parameters including
delay, 10 bands of parametric EQ, high pass filtering, gain, phase and muting, when under
Vu-Net control.
The DD12 has a variety of rigging options, designed with Martin Audio's considerable experience
in system deployment. This allows phenomenally quick system rigging and de-rigging, particularly
because there are no amplifier racks to set up and break down.
The DD12 is available in both Standard (non-IP rated) and IP24 Rated versions. (Note: The
IP rating is only valid for the IP24 Rated version when the DD12 is used in portrait mode,
i.e., upright.) Alternatively the Standard version may be upgraded to IP24 rating by fitting the
optional weatherproof cowl (Part No. ASF15019) and weatherproof grille (Part No. HAG01145).
The IP24-rated version is suitable for outdoor use in virtually any weather condition.
Note: The DD12 must be returned to either Martin Audio or an approved dealer to have the
weatherproof cowl and grille fitted to meet the IP24 specification.
Note: To attain IP24 rating, all connectors and cord sets must also meet the IP24 rating –
available as accessories from Martin Audio.
