AKG Acoustics WMS 40 - Manual (Page 70)

Fitting all components into flight cases as well
as the shortest possible setup time are essential
for festivals with several acts performing in
succession. While one performer is on stage,
backstage preparations for the following act
must be completed so that it can be started
without any drawn-out interruptions due to al-
terations or soundchecks. Wireless systems in
particular require meticulous performance tests
to be carried out – both regarding RF and audio
signals – before they are connected to the FOH
mixer. The advanced software of the SR 4000
receiver makes all this easy. Rehearsal Mode,
Auto Setup, and Frequency Scan are just a few of the features that help set up all the RF
connections quickly and eficiently.
However, the ultimate quality of the audio sig-
nal delivered by the receiver can only be tested
by connecting the receiver to the mixer, which
is practically impossible once the show has star-
ted.
Two HPA 4000 headphone amplifiers, each
connected to five receivers, eliminate this pro-
blem, enabling you to check audio signal quali-
ty quickly and reliably without an additional
mixer.
In the example shown above, a complete
10-channel wireless system including antenna
splitters, power supply unit and headphone
amplifiers can be fitted into a compact 8 U
rack. You can also fit two small flight cases with
five charging units each for the transmitters, so
that all transmitters can be charged completely
and simultaneously within just one hour.
And, the complete tour sound package takes up
so little space that it can be transported in a
standard station wagon – the ideal solution for
touring bands.

Tour Sound
The WMS 4000 is specifically suited for small tour setups,
since the large variety of selectable channels allows you to
find a working setup for practically any application.
For example, a complete 4-channel system can be fitted
into a flight case measuring only 6 U high (see below).
Thanks to the integrated PSU 4000 power supply unit and
the PS 4000 antenna splitter with two front antennas, all
you need to do is connect a single power cable! All other
components, such as the transmitters, can be stored in a
2 U drawer.
