 Mix-Minus-Pak
The Mix-Minus-Pak allows the generation of a clean feed
from mixer output minus the telephone fader, producing a feed suitable
for a telephone hybrid. The unit takes the mixer output and a tap from
the telephone fader and out-phases the telephone signal, thereby removing
it, producing an output equivalent to the mixer output minus the telephone
fader. A multi-turn preset is provided for adjustment of cancellation
null. A Band pass Filter of 300Hz to 3.5kHz is provided as standard on
the output to pre-condition the signal to the telephone hybrid. Full frequency
range versions for ISDN use can also be supplied. Any number of units
can be connected to allow generation of multiple feeds for conference
calls.
Housed in a convenient 1U aluminium case, the Mix-Minus
Pak can be free standing, easily mounted into a woodwork system, or fitted
into a rack with use of the Alice Rack-Panel. Audio inputs and outputs
are via Neutrik XLR connectors and mains input is via an IEC.
