Sensitivity
+18 / -78dB for Mic/Line Inputs
Equivalent Input Noise -127dB (150 Ohm source)
Distortion
-1dBFS @ 1kHz - Better than 0.003%
-20dBFS @ 1kHz - Better than 0.006%
-60 dBFS @ 1kHz - Better than 0.3%
Frequency Response 20Hz to 20kHz +/- 0.5dB on Mic/Line Inputs
Input CMR
(Common Mode Rejection)
>75dB (Typical 85dB) on Mic/Line inputs
Crosstalk -105dB or better on adjacent channels with 0dBFS tone at 1kHZ on Source
Notes
Analogue input for 0dBFS can be pre-set globally to +28, +24, +22, +20, +18 or +15dBU
Pre-fader headroom on mic inputs is adjustable globally from +24 to +36dB in 2dB steps
For analogue inputs/outputs the system can handle analogue levels of up to +27 dBu from
analogue input to analogue output at line up
These levels must be attenuated in the system before they are fed to digital outputs
