sibility to use these cables in an active 2-way system con-

LF-C ABLES - B ALANCED OR U NBALANCED ?
For LF-cabling – all the low current wiring – your best
choice are balanced cables (2 signal conductors + ground
shielding) with XLR-type connectors or stereo phone
plugs. The cables should be step-on proof, shielded, and
never longer than really needed. Too many too long ca-
bles mostly lead to confusion and generate unnecessary
problems. Of course, connecting unbalanced cables with
monaural phone plugs to the PowerMate’s in- and out-
puts is also possible and in most cases no interference
will occur because of its superb grounding managing sys-
tem. 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 bal-
anced in- and outputs. In a balanced signal path the cable
screen provides gapless connection of all metal parts, of-
fering efficient shielding against the induction of external
noise. The balanced cabling in conjunction with the com-
monmode rejection of the PowerMate’s input stage effec-
tively eliminates even existing artifacts of interference. All
inputs of the PowerMate provide balanced audio connec-
tions and high common-mode rejection. The mixing stage
outputs – FX, AUX, MASTER, MON, 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 men-
tioned above – when longer cables are involved, using
stereo phone plugs and balanced cables are the better al-
ternative. The diagrams below show the pin assignments
of plugs and cables that are used with the PowerMate.
5.3 Setting up
1. Place the PowerMate in a way that allows unob-
structed operation and connect the mains cord.
2. Try to locate the best position where you want to
place the loudspeaker systems. If possible, the
woofers should be placed on the floor while the Hi
cabinets’ most favorable position is above the Lo
cabinets, on the same vertical axis. It is important
that the lower edge of the Hi cabinets is approxi-
mately at the same height level or slightly higher as
the heads of the audience. Either you use the pole
