Mic Inputs
You can connect dynamic, condenser, tube, and ribbon microphones to the mic inputs. Use
the Phantom switch to provide phantom power to the microphones that require it. For more
information, read the „Phantom“ section on page 14.
Specifications: XLR connectors, input impedance 10 kOhm, maximum input level +14.5 dBu
(Gain knob hard left).
IMPORTANT: Below you can read more information regarding Input Selection.
Line Inputs
You can connect and record up to four line signals. Besides keyboards and synths you can
connect here other external sources like preamps or channel strips.
All four balanced line inputs are routed 1:1 to the converter and monitoring section. Level
adjustment is not possible.
Specifications: 1/4" stereo jacks, unbalanced input impedance 10kOhm, balanced input
impedance 20kOhm, maximum input level +22.5 dBu.

Mono and Stereo Signals.
Input Selection: Microphone, Instrument and Line Inputs
Taking into account both microphone inputs, the two instrument and four line inputs, you
have eight analog inputs at your disposal. Any four of the eight analog inputs can be used
simultaneously for recording purposes.
The selection is defined by the assignment of the corresponding inputs. This has the added
advantage that the channel configuration can be directly and intuitively made out by the
assignment of the connections, plus there is almost no need for switching.
The input selection follows this provision:
Line 1 has preference over Mic Input 1
Line 2 has preference over Mic Input 2
Instrument input 3 has preference over Line input 3
Instrument input 4 has preference over Line input 4
IMPORTANT: you should bear in mind the following conditions:
To record microphone signals, Line 1 and/or Line 2 ought to be free. If you cannot hear a micro-
phone signal, check whether Line 1 or 2 are free or not.
To record Line inputs 3 and 4 or to listen to a stereo signal through Line 3 and 4, Instrument 3
and 4 ought to be free. If you cannot hear a line signal, check whether Instrument inputs 3 and
4 are free or not.
Monitoring Mono and Stereo Signals
We have also managed to keep Instrument and Line input monitoring free of any switching,
Depending on the situation, you must only use the appropriate inputs to either listen to them
on one channel (R) or in stereo (L and R):
Only Instr 3 engaged ›› Mono monitoring
Only Instr 4 engaged ›› Mono monitoring
Instr 3+4 engaged ›› Mono monitoring for both
Only Line 3 engaged ›› Mono monitoring
Only Line 4 engaged ›› Monitoring on the R channel
Line3+4 engaged ›› Stereo monitoring
