1 - 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 operating level and can also be useful for setting system gain structure. Clip LEDs warn 
the user of input overload and operate at +19 dBu. 
 

2 - Preset Store and Recall 

These controls provide access to the 45 presets stored within the device. Pressing the store button allows the user to 
name a preset and choose which memory location it will be held in. Pressing store button again completes the process. 
The Recall function operates in a similar way, pressing the recall button allows the user to select which preset they 
require, pressing the button for a second time, then confirming, recalls the new DSP settings. 
Note that presets cannot be stored or recalled when Secure mode is activated 
 

3 - 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 and back to the default screen. If 
operating a stereo linked preset, the channel name will indicate the channel pairing. For example ‘A+B’ means both input 
A and B parameters. The name of the output will be shown briefly at the top of the display when stepping onto an output. 
 

4 - Edit Select Buttons 

The currently selected edit parameter page is displayed on the bottom left corner of the LCD. Pressing the edit select 
buttons moves through the available parameters for the current input or output. 
 

5 - Text Display 

Preset, channel, parameter and status information is shown on the 2x 24-character text display. In most screens the 
currently selected channel is displayed on the upper line and the edit parameter on the lower line. To simplify the display 
and enhance security, some parameters or parameter pages are omitted when not relevant. 
 

6 - Parameter Knobs 

Three velocity sensitive parameter knobs are used to adjust parameters shown on the display. Up to three parameters at 
a time are displayed on the screen. The parameter name is shown above the parameter value in each of the three 
screen sections. The parameter knobs have a fixed association with the screen sections; the rightmost parameter knob 
adjusts the rightmost parameter and so on. 
 

7 - Output Signal / Limiter Indication 

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

8 - Mute Buttons and Status LEDs 

Each output has a mute button and associated mute status LED. Pressing the button toggles the mute on and off.X 
Note that the mute buttons do not function when the Secure mode is activated.
