Input Signal Indicators – A set of three pairs of LED’s indicate signal present, +4dBu and input clip for both channels. The signal present LED’s operate at approximately –40 dBu, giving a useful indication of even relatively low input signal levels. The +4 dBu LED’s are intended to show nominal operating level and can also be useful for setting system gain structure. Clip LED’s warn the user of input overload and operate at +19 dBu.

Program Store and Recall – these controls provide access to 45 presets. 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. The unit allows the user to set up user programs with full access to all parameters.

Note that presets cannot be stored or recalled when secure mode is activated.

Channel Selection 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.
