AKG CM12/8 Manual page 16

1. Introduction
The CM12/8 is a high quality 12 input, 8 output audio matrix mixer. Any combination of inputs may
be routed to any combination of outputs. Output channel gain can be adjusted from +10dB to ­
68dB in 1dB increments, plus Off. Input send levels to each output offer three selectable gains: -6dB,
0dB, +3dB, plus Off. Each output has a Mic/Line selector switch. The Line position drives other line
level equipment, while the Mic position is optimized for recording and other mic level applications.
The CM12/8 has an RS-232 port for remote set-up or control by a computer or other RS-232 compat­
ible controller. More than one CM12/8 may be coupled together when applications call for more
than 12 input channels.
