Mix matrix mode (auxes and amplifier outputs)
Input sends to each output continuously variable from -40.0dB to _15.0dB in 0.1dB steps plus mute
Limiter
Threshold +18dBu to -12dBu (auxiliary outputs); +42dBu to +20dBu (amplifier outputs)
Attack time 0.1 to 91 milliseconds
Release time 2, 4, 8, 16 or 32 times the attack time
Clip/D-max Limiter
Look-ahead attack time,Fast, Medium or Slow release times
*FIR Filtering enabled in later firmware release — 4000 taps with DEQ globally disabled
** DEQ enabled in later firmware release
