Patchbay Applications
The individual access that the patchbay offers to each of the
main sections of the
POWERSTATION
allows the mixer, the
graphic equaliser and the power amplifier to be interfaced
separately to external equipment if required, or used in
different configurations for particular applications. Three
typical examples are given below:
Example 1
In this example the outputs from the
console are used to feed an external
power amplifier. The feed may be
taken pre-graphic equaliser (from
the main outputs jacks) or
post-graphic equaliser (from the
graphic EQ outputs jacks). In either
case, plugging a jack into the output
sockets breaks the normalling to
bypass the following sections (see
diagram on previous page).
Example 2
In this example a feed from an
external mixer, for a secondary band
perhaps, plugs directly into the
power amplifier jacks, bypass the
POWERSTATION
mixer and graphic
equaliser. Alternatively the external
feeds could plug into the Graphic
EQ Inputs jacks, providing some
signal correction if required.
Example 3
If only a mono PA output is
required, one channel of the power
amplifier can be fed from the Mono
Output by overplugging as shown,
and the second channel may be used
to drive, for example, foldback from
Aux 1. In both cases the Graphic EQ
is left in the signal path.
