Channel Equaliser
Signal applied to line input and measured at the channel insert send. EQ switched in with EQ controls centred in shelf mode.
Measurement Conditions Value
Output Headroom >+26.5dBu at onset of clipping
THD+Noise +20dBu @ 1kHz
+20dBu @ 10kHz
<0.003% at 20dBu @1kHz (filter 20Hz to 20kHz)
<0.003% at 20dBu @10kHz (filter 20Hz to 40kHz)
Noise <-80dBu
Overall Channel Signal Chain Specications
Signal applied to Line Input of a channel and routed to specified output by shortest path. All controls set flat, out or at unity gain
as appropriate. Pan set to full left or right.
