4. Installation

4.1 Rack mounting

The packaging of your mixing console contains two 19" rack mount wings which
can be installed on the side panels of the console.
Before you can attach the rack mount wings to the mixing console, you need to
remove the screws holding the left and right side panels. Use these screws to
fasten the two wings onto the console, being careful to note that each wing fits
a specific side. With the rack mount wings installed, you can mount the mixing
console in a commercially available 19" rack. Be sure to allow for proper air flow
around the unit, and do not place the mixing console close to radiators or power
amps, so as to avoid overheating.
◊
Only use the screws holding the mixing console side panels to fasten
the 19" rack mounts.

4.2 Cable connections

You will need a large number of cables for the various connections to and from
the console. The illustrations below show the wiring of these cables. Be sure to
use only high-grade cables.

4.2.1 Audio connections
Please use commercial RCA cables to wire the 2-track inputs and outputs.
You can, of course, also connect unbalanced devices to the balanced
input/outputs. Use either mono plugs, or ensure that ring and sleeve are bridged
inside the stereo plug (or pins 1 & 3 in the case of XLR connectors).
◊ Caution! You must never use unbalanced XLR connectors
(pin 1 and 3 connected) on the MIC inputs if you intend to use the
phantom power supply.
