Martin Audio expands Differential Directivity systems
Martin Audio’s DD12, the latest addition to the company’s
Differential Directivity Series
COMBINING STATE-OF-THE-ART
transducers with Differential
Dispersion horn technology and
Class-D ampli cation, the multipurpose DD12 loudspeaker forms
the latest addition to Martin Audio’s
comprehensive range.
According to the manufacturer,
its patented rotatable Differential
Dispersion technology delivers a
more consistent coverage than
traditional X x Y horns. The two-way
powered speakers also feature
onboard DSP, a switched mode
power supply with Power Factor
Correction (PFC), and internal
memory allowing for factory ‘plugand-play’ or user-generated DSP
preset snapshots to be recalled via
a selector switch on the rear panel.
Whether con gured as an element
in a stand-alone system or part
of a larger MLA/MLA Compact
system, individual DD12’s can be
controlled and monitored from a
laptop or wireless tablet PC via the
manufacturer’s VU-NET proprietary
software. Connections to PCs can
be made directly via USB, or via
Martin Audio’s U-NET network and
Merlin loudspeaker and network
management system.
The cabinet supports surface,
ceiling and pole mounting, and has
a universal tilting bracket, making it
suitable as a PA in small-to-medium
installations.
As well as the DD12, Martin has
also released the 15-inch selfpowered PSX subwoofer. Intended
as a companion for the DD6, XD12
and XD15 loudspeaker systems, it
comprises a 4-inch voice coil, longexcursion driver in a re ex-ported
The Martin Audio PSX sub
enclosure. It houses two channels of
Class-D ampli cation – one channel
for itself and one channel to power
an XD12, an XD15, or up to three
DD6s.
Producing a total peak output of
2,400W – with 1,400W allocated to
the sub and the remaining 1,000W
to drive the associated system – the
operating range of the PSX is 48 to
150Hz with a peak SPL capability of
136dB at 1m.
Onboard DSP performs delay,
crossover and EQ functions, while
like the DD12, the sub and its fullrange system can all be controlled
and monitored via VU-NET software.
The speaker housing is made
from tour-grade plywood coated in
hard-wearing polyurethane with a
Declon backed steel grille protecting
the cone. Practical features include
a pole-mount tting on the top
surface, bar handles and protective
skids. When stacked, the skids on
the base of the enclosure align with
recesses in the top of the enclosure

Cost effective addition to JBL Precision Directivity range
INTRODUCED AS a cost effective
addition to the Precision Directivity
range of loudspeakers from JBL
Professional, the PD6000 series
is aimed at midsize to large
venues, sitting between the larger
PD700 and more compact AE
Seri es systems. The 14-strong
range leads a number of launches

brand, including Commercial
Series ampli ers and mixers, and
the LSR310S powered studio
subwoofer.
The PD6000 series is con gurable

loads whilst operating with both
70V and 100V distributed audio
systems without the need for
a separate transformer. They
also include a universal power
supply and accept an Ethernet
control cable for use with the
manufacturer’s CSR-V wall-mount
volume control.
The mixers are described as
‘perfect for background music,
paging, and security’, boast minimal
front-panel control and rear-panel
RCA inputs plus Euro-block mic/line
input and output connectors. Other
features include priority muting,
VOX ducking and mic phantom
power.
Moving from the installation sector
to the studio market, the LSR310S
powered subwoofer is intended
for recording and postproduction
applications, having been optimised
for use with JBL’s 3 Series monitors.
The LSR310S is described as
completing the 3 Series, extending
its low-frequency response into
the 20Hz range. It is driven by
a 200W Class-D ampli er and
incorporates a 10-inch highexcursion woofer working alongside
the manufacturer’s patented Slip
Stream Port to deliver LF response
below 27Hz, with a peak output
of 113dB SPL. It also boasts
a selectable XLF extended low
frequency setting that emulates the
augmented low frequency response
heard in a dance club environment.
Other features include balanced
XLR and ¼-inch inputs, a selectable
input sensitivity switch and three
crossover settings – ‘80Hz’ (which
implements high and low pass
lters), ‘XLF’ and ‘External’ (which
bypasses all ltering, allowing the
use of an external crossover).
Finally, the manufacturer has
introduced the VRX Line Array
The LSR310S subwoofer from JBL
Calculator as a design tool for its
VRX Constant Curvature Series.
Up to four audience planes can be
modelled on the software including
features such as ground-level
seating, multiple balconies, stage
areas and rear wall boundaries. In
addition, an ‘array con guration’
page is included to show the size,
weight, and rigging parameters with
built-in working load limit safety
warnings. The software is available
for download now.
