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.
