Audio performance
Frequency response: 20Hz to 20kHz;+1 to -1.5dB for input to send; +1 to -1.5dB for return to output
THD+N: <0.01%, at 1kHz nominal output level; <.01% at 1kHz insert returns to main output; .01% at 1kHz input to main
outputs
Dynamic Range: Instrument input to send:
-110dB (unweighted) minimum Input to Send with Relay Bypass on
-120dB (unweighted) Input to Send with Noise Gate on
-97dB (unweighted) typical instrument to main outputs in Bypass
Sample rate: 44.1kHz
Return Mix: When the Return Mix option is selected, MPX G2 will mix the analog Aux inputs with the post converter output
signal from the DSP.
Throughput delay without send/return loop: Input to Main Output <3ms, nominal
