Balanced Inputs
The ARC-8 has balanced audio inputs on channels 3-7 input. They use RJ45 connectors as illustrated
below. Pins 5,7,8 are not connected.
The cable used with these connectors is CAT5. This cable has 4 twisted pairs of wires. The twisted pairs
are identified by color (ie: orange, orange... green,green... etc). Arrakis ARC consoles use 2 pairs for left
and right audio [the two pairs used by ethernet as the transmit (green) and receive pairs (orange)] . Left
is the orange (ethernet transmit pair). Right is the green (ethernet receive) pair.
Arrakis supplies 20 foot CAT5 cables with RJ45 connectors on each end with the console. Cut the cables
in half (or to the length that you need). Then ttach the desired connector to the unterminated end of the
cable (XLR, TRS phone, RCA, etc)
The balanced inputs are >10,000 ohm input impedance and levels are set for +4dBu signals.
