Page 9 input signal indicators a set of three pairs of leds indicate signal present, +4dbu and input clip for each channel. The signal present leds operate at approximately –40 dbu, giving a useful indication of even relatively low input signal levels. The +4 dbu leds are intended to show nominal op...

Page 13 many of the processing elements in each input and output path have features that may be controlled by the user, such as gain, frequency or limiter threshold. We call these adjustable features parameters. A parameter may be adjusted when it is displayed by turning one of the three-parameter k...
