INPUT SIGNAL INDICATORS

A pair of 8-segment LED bargraph meters indicate input level for each channel. These read peak
level from signal present at – 40dBu to clip warning at +19dBu. When the clip warning light first
illuminates, there is an additional 1dB of headroom available as a safeguard.

STORE AND RECALL

These controls provide access to the unit’s 45 presets. To see them in action, go to page 10.

CHANNEL SELECT BUTTONS

The currently selected channel is displayed on the top left hand corner of the LCD. Pressing the
channel buttons scrolls through the available input and output channels and finally through the utility
functions. If the current preset is stereo linked, the screen will show the channel pairing whose
parameters will both be edited.

EDIT SELECT BUTTONS

The currently selected edit page is displayed on the bottom left corner of the LCD. Pressing the
edit select buttons moves through the available parameters for the currently selected channel.

TEXT DISPLAY

The main display shows preset, channel, parameter and status information. In most screens the
currently selected channel is displayed on the upper line and the edit parameter on the lower line.

PARAMETER KNOBS

These velocity sensitive encoders are associated with the current on-screen parameters. For
example, the value shown on the screen above the letter F1 is controlled by knob F1.

OUTPUT LEVEL INDICATORS

Two LEDs are provided for each output channel. These show the signal level relative to the limiter
threshold. The green LED will light when the signal is 6dB below the threshold and the red ‘limit’

7

LED will light when the limiter threshold is reached.

MUTES

Each output has a mute button and associated status LED.

Note that the mute buttons do not function when the Secure mode is activated. See below for
details of Secure mode.
