Electro-Voice STEREO POWERED MIXER PSX2200 - Manual (Page 19)

CABLING
The ac power cord comes with the PSX. The quality of all other cables are your responsibility. Carefully chosen high quality cables are the
best precaution to prevent problems during operation. The following wiring alternatives are recommended to provide a trouble free operation
of your setup.
SPEAKER CABLES
From our experience as a manufacturer of loudspeaker systems we’ve learned that flexible speaker cables with a rubber jacket (10 - 16
gauge, depending on length) used in combination with NEUTRIK SPEAKON plugs and sockets, are the best choice to guarantee optimal
connection of loudspeaker systems. In accordance to the corresponding diagram, the SPEAKON plugs are connected on the PSX rear panel.
You can also consider the use of 4-wire cables where pins 2+ and 2- are also connected. This provides you with the possibility of using these
cables with active 2-way system configurations, as well. Professional-quality speaker cables with SPEAKON connectors and all other cables,
plugs, and sockets are available at your Electro-Voice dealer.
LF-CABLES – BALANCED OR UNBALANCED?
For all low current wiring , your best choice are balanced cables (2 signal conductors + ground shielding) with XLR-type connectors or with
stereo phone jacks and plugs. The cables should be step proof, shielded, and never longer than really needed. Too many too long cables
mostly lead to confusion and generate unnecessary problems.
Of course, you can also connect unbalanced cables with monaural phone plugs to the PSX’s inputs and outputs and because of its superb
grounding managing system in most cases no interference will occur. Still, there is a minimal risk that problems could arise and we believe
that this is reason enough to keep on reading. Generally spoken, if you have the choice, a balanced LF-cable is always the better solution.
Today’s modern audio equipment – like amplifiers, equalizers, FX units, mixing consoles, and even some keyboards – offers balanced in-
and outputs. In a balanced signal path the cable screen provides the gapless connection of all metal parts, offering efficient shielding against
the induction of external noise. The balanced cabling in conjunction with the common-mode rejection of the PSX’s input stage effectively
eliminates even existing artifacts of interference. All inputs of the PSX provide balanced audio connections and high common-mode rejection.
The mixing stage outputs – AUX, MAIN, EQ, etc. – are laid out in GND-SENSING technology – a special pin assignment of the output jacks,
offering all advantages of the balanced signal transmission, but lets you also connect monaural phone plugs without a problem. Nevertheless
– as mentioned above – when longer cables are involved, using stereo phone plugs and balanced cables are the better alternative. The
diagrams below show the pin assignments of plugs and cables that are used with the PSX.
