Overall Channel Signal Chain Specications
Signal applied to Line Input of a mono channel, and routed to specied output by shortest path. All controls set at, out or at unity
gain as appropriate. Pan set to full left or right.

Overall Console Noise
Measured at main outputs, channels routed as required with pans / balance controls centred, using Line input with termination. All
controls set at, out or at unity gain as appropriate, channel and master faders calibrated for 0dB.
