Specifications
Analog inputs
The tip connector is the Hot (+) signal while the ring connector is the Cold (-) signal.
The shield is always ground.
The input characteristics change depending on which type of input is selected:
Line
Differential input impedance: 20K ohms, 10K ohms to ground per leg
0dB input level (gain slider at minimum): +18 dBu (6.2Vrms or 17.5V p-p)
Slider gain range: 0 dB to +63 dB
Guitar
Input impedance: 1 Meg ohms
0dB input level (gain slider at minimum): +12 dBu (3.1Vrms or 8.8V p-p)
Slider gain range: +6 dB to +69 dB
Mic
Differential input impedance: 1.8K ohms, 900 ohms to ground per leg
0dB input level (gain slider at minimum): +6 dBu (1.6Vrms or 4.4V p-p)
Slider gain range: +12 dB to +75 dB
EIN (Equivalent Input Noise): -129 dBu
When monitoring, input to output latency is XXms. FIXME
Analog outputs
The main output and headphone volumes are set using the touch panel slider with a
maximum output level of 9.5 dBu (2.3 Vrms or 6.5V p-p).
outputs are impedance balanced with an output impedance of 120 ohms on
each leg, yielding the noise cancelling benefits of a balanced connection.
However, only the tip has an active signal present.
