Typical DB-25
connector
Note: These inputs can be used as four
mono inputs. The default names of these
inputs correspond to the inputs as follows:
Mic 1 is Line 9 Lt In
Mic 2 is Line 9 Rt In
Mic 3 is Line 10 Lt In
Mic 4 is Line 10 Rt In.
When used as four mono sources they are
still line level inputs, and they are not
internally connected to the four mic
preamps.
