PSX USER GUIDE

INTRODUCTION

Thank you for purchasing this Martin Audio PSX self-powered subwoofer.

The PSX combines Class D amplification, powerful on-board DSP and networking capability with
a 15” (380 mm) LF driver in a reflex enclosure. The PSX is intended to be used in conjunction
with active or passive full-range loudspeakers, extending the system’s overall LF response. It is
ideal for use with Martin Audio’s XD15, XD12 or DD6 cabinets.

This User Guide provides a detailed explanation of the PSX’s features and options. Please take
the time to read through the Guide even if you are experienced with other Martin Audio products.

Thank you again for placing your confidence in Martin Audio products.

PSX USER GUIDE

OVERVIEW

The PSX is an active subwoofer with a single 15” bass driver. It is intended to be used in
conjunction with passive, full-range cabinets such as Martin Audio Models DD6, XD12 or
XD15. It may also be used with similar, compatible cabinets from other manufacturers. It has
an integral, specifically-designed, two-channel DSP amplifier module: one channel drives the
internal subwoofer driver, the other is available to drive the passive cabinet(s) it is used with.

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 unit. With the aid of Vu-Net network control software,
outstanding levels of consistent, high quality audio can be delivered. The PSX can be used
either singly or stacked in multiples. Optimised speaker push button presets are accessible via
the rear panel.

The PSX 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 PSX 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 PSX cabinet design benefits from Martin Audio’s considerable experience in system
deployment. The top face is fitted with a pole mount socket, and top and bottom are designed
so that multiple units can be simply and securely stacked. This allows very quick rigging and
de-rigging, particularly because there are no amplifier racks to set up and break down.

The standard PSX may be converted to a version with an IP24 rating for outdoor use in virtually
any weather condition by fitting the optional weatherproof cowl (Part No. ASF15040).

Note: the weatherproof cowl assembly must be fitted by an approved dealer, to a torque of

0.1 Nm in order 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.

PSX USER GUIDE

The two versions of the PSX can be distinguished by the visibility of the IP24 Marking. Below is
a photograph of the non-IP rated PSX, which just has a bezel trim (shown above) on the amplifier
faceplate. This bezel covers the IP24 rating plate, clearly indicating that it does not comply in
this format. This version should not be exposed to dripping or splashing and no object filled with
liquids, such as vases, should be placed on it.

SIGNAL, U-NET AND INDICATORS

The connection panel is on the rear of the cabinet and features a female input XLR and a male
Link XLR for balanced analogue or AES/EBU digital input signals. Input type is selected via Vu­Net software.

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
additional PSX 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. Either
connector can be used as input or link.

The output of the second power amplifier channel is available on a female Neutrik® NL4
connector to drive any full-range passive speaker cabinet(s) that the PSX is being used in
conjunction with.

A single red LED indicates power and two bi-colour LED’s indicate U-Net network integrity.
Green indicates that the network is stable and red indicates an error.

PSX USER GUIDE

PSX CONNECTIONS

MAINS

The PSX has a Universal PSU suitable for direct connection to most mains voltages throughout
the world. It is fitted with a Neutrik® PowerCON TRUE1 single phase mains inlet. If you are not
using a Martin Audio power distribution cable system, a mating Neutrik® PowerCON TRUE1
(NAC3FX) outlet connector must be used. For outdoor use all mains power connectors should
be rated to IP65. See the sections on Electrical Safety and Rear Connector Panel (Mains Inlet)
for more details.

AUDIO INPUT AND LINK

Analogue inputs should be connected with a good quality 3-pin male XLR wired to good quality
twin screened cable. This is particularly important if the input cable run is long (e.g., from the
FOH position to stage). Good quality cable will minimise losses. The Link outputs should use
a similarly high quality female XLR. The line driver at the signal source must be able to drive
the combined load of all PSXs (and any other cabinets) being linked (See PSX Specifications).
Wiring is the industry standard for balanced connections:

PIN CONNECTION

1 Ground or shield
2 Signal ‘hot’ (‘+’)
3 Signal ‘cold’ (‘-’)

AES/EBU input connections are identical to analogue, but the cable used must be a dedicated
low-capacitance digital audio type with a characteristic impedance of 110 ohms, such as Belden
1800F or 1696A. The PSX’s inputs can only be enabled for digital use via the Vu-Net software
application.

For more details of the Merlin and U-Net please see the relevant User Guides.

USB

The Type B USB port allows connection of a PC for system control and monitoring purposes. For
simple set-ups using the internal presets, this connector may be ignored.

The USB port may be used for network control purposes in smaller systems in preference to the
U-Net system (see following page). USB connectivity imposes a 5 m cable length limit: if this is
too restrictive, a Silex USB-to-Ethernet convertor is available from Martin Audio as an optional
accessory (Part No. ASF14103), which allows operation over 75 m of Cat 5 cable. It is a self­contained unit which is small enough to be attached to rear of the PSX cabinet using Velcro or
similar (if wished); this arrangement would help to keep on-stage wiring tidy.

PSX User Guide V1.0

18

PSX USER GUIDE

U-NET

When a networked system with multiple PSXs requires long cable runs – possibly including other
Martin Audio network devices - the dedicated U-Net Bus must be used as opposed to USB,
which is only suitable for short cable distances. Connections are made using Cat 5 cables fitted
with 8-way push-pull latching connectors compatible with ODU Series K. Robust Cat 5 cable
such as Neutrik® Etherflex or Belden 1305A should be used; this will ensure reliable network
connections of up to 125 metres between network ports.

U-Net uses a redundant ring fault-tolerant protocol, so connections are “daisy-chained” between
all units on the network, going from Port 1 on the first unit to Port 2 on the next, and so on. The
last network link is back to Port 2 on the first unit, thus completing the loop. The U-Net network
will operate perfectly well without a closed loop but it is strongly recommended to use this
option so that the network will continue to work in the event of a break in cable or disconnected
connector.

Ready made tour-grade network cables are available as accessories from Martin Audio in a
variety of lengths, suitable for inter-cabinet patching to FOH-to-stage runs

SATELLITE SPEAKER OUTPUT

A female Neutrik® NL4 socket is fitted, which carries the output of the power amplifier‘s
second channel. As the PSX will always be used in conjunction with a full-range speaker system
(“a satellite”), it may be convenient, in the case of passive speakers, to use this to drive the
satellite. Suitable Martin Audio cabinets are the DD6, XD12 or XD15.

The amplifier’s satellite output has a peak power of 1000 W into 8 ohms, so consideration must
be given to the rating of any speaker system connected.

PSX USER GUIDE

SYSTEM CONNECTIONS

The audio input should be connected to the first co-located cabinet and short linking cables
used to “daisy-chain” between adjacent cabinets, from the Link output of one cabinet to the
input of the next.

U-Net network cables can be connected in the same way, except that to create a “ring”, a long
U-Net cable should go from the final cabinet in the group to the next device on the network. This
could be more PSXs on the other side of the stage, other U-Net enabled speakers or amplifiers,
or a Merlin controller.

When many PSXs are in use, or when they form part of a larger system (typically of MLA, MLA
Compact or MLA Mini cabinets), Vu-Net offers equalisation and monitoring functions so that the
array performance can be adjusted and analysed.

PSX USER GUIDE

RIGGING

The PSX is designed to be ground-stacked directly on a stage or floor. Skids are fitted to the
lower surface to provide cabinet protection; the top surface has corresponding recesses to permit
multiple PSXs to be easily stacked.

An optional Pole Mount is available (Part No. HAM09224), which may be inserted into the
socket on the top of the cabinet to permit a full-range cabinet to be integrated into a single
assembly.

The picture below illustrates a Martin Audio XD12 full-range cabinet paired with a PSX using
the Pole Mount:

PSX User Guide V1.0

PSX USER GUIDE

ACCESSORIES

WHEELBOARD AND COVER

The PSX can be fitted with an optional wheelboard and tough canvas cover set
(Part No. ASF7038) to allow easier transportation. The wheelboard is attached to the
front of the cabinet using slam-latches which locate in the metal lugs on either side of the
front of the cabinet. Once fitted the cabinet is tipped forward onto the castors and the canvas
cover can be dropped over the top for transportation, protecting the cabinet and amplifier
module.

Pole Mount:

The PSX is fitted with an M20 screw-in top-hat fitting on the top of the cabinet for attaching a
compatible distance rod.

PSX User Guide V1.0

22

PSX USER GUIDE

The Pole Mount (Part No. HAM09224) is a 35 mm dia. telescopic wind-up pole with an M20
fitting. This is compatible with the PSX and also with the top hat fitted to all Martin Audio and
most OEM speaker products. König & Meyer also manufacture a number of suitable poles.

The pole must be securely inserted into the screw fitting; ensure that it is screwed tightly.
When used in combination with the PSX, the HAM09224 is rated for use with Martin Audio
speakers up to and including the XD15 in weight. When fitting a speaker to the Pole Mount,
do not exceed the weight of an XD15 (32 Kg), as the resulting assembly will be unsafe.

PSX User Guide V1.0

23

PSX USER GUIDE

PRESET SELECTION

The PSX has 15 internal Preset memories. The memories can hold a set of cabinet parameters
which optimise the PSX for use in a particular situation.

The first three memories (1 to 3) are pre-loaded with Factory Presets as follows:

• Preset 1 - for using the PSX with a Martin Audio DD6 cabinet

• Preset 2 - for using the PSX with a Martin Audio XD12 cabinet

• Preset 3 - for using the PSX with a Martin Audio XD15 cabinet

Presets are selected by pressing the Select button on the rear panel. The adjacent seven-segment
LED display scrolls through the Presets with successive presses of the button, cycling back to
the beginning after the last Preset (see Note below).

To differentiate them from the memories holding Factory Presets (1, 2 and 3), the User memories
use the first six letters of the alphabet, duplicated with a decimal point, instead of numbers, as
follows:

A b c d E F A. b. c. d. E. F.

Note: When shipped from the factory, the User memories are empty. It is only possible to select
memories that contain Presets: empty memories are ignored. Thus “out-of-the-box”, Preset
selection will cycle through Presets 1 to 3 only.

The 12 User memories can be used to store your own presets, created using Vu-Net. For full
details of Vu-Net control please see the Vu-Net User Guide available from the Martin Audio
website www.martin-audio.com.

If a preset number is flashing it indicates that Vu-Net has modified a preset in some way. To
restore a Preset to its unmodified state, press the Select button repeatedly until the display has
cycled back to the original Preset location. This will recall the stored version and the number or
letter will no longer flash - indicating that the Preset has been returned to its stored state. While
the PSX can be operated with a modified set of parameters, the internal User Presets can only
be overwritten by a command from the Vu-Net software.

PSX User Guide V1.0

PSX USER GUIDE

VU-NET OPERATION

Vu-Net is Martin Audio’s monitoring and control application. It may be used with the PSX, either
stand-alone or in conjunction with other Martin Audio network-ready products such as MLA,
MLA Compact, MLA Mini and DD12. Connection between a PC and the PSX (or other system
components) may be made:

• directly on a one-to-one basis via USB (note the maximum USB cable length is 5 m),

• directly on a one-to-one basis via a Silex Ethernet-to-USB converter, or

• by using a Merlin system processor as a PC-to-network hub. When a Merlin is in use,

interconnection between the various cabinets in the system is via the U-Net network
protocol.

Vu-Net is also used to upload DSP parameters to the PSX, and to perform system firmware
checks.

It is important to realise that once a set of DSP settings has been uploaded into the system, the
presence or absence of a U-Net network in no way affects normal audio operation; cabinets will
continue to pass audio with their last known configuration even without an operational U-Net
network. This applies also to power-cycling: the PSX retains the last-used set of parameters when
powered down and reloads them when re-powered, whether they were a Preset or a modified set
of parameters loaded from Vu-Net.

DSP functions which can be controlled via Vu-Net include level, mute, polarity, input selection,
delay, high pass filter and 10 bands of parametric EQ for both the subwoofer itself and the
auxiliary output. User Presets can be stored and recalled via the rear panel switch after the
network is disconnected.

For full details please see the Vu-Net User guide which is available from the Martin Audio
website.
