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:
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 self-
contained 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.
