1.) Mute Keys - Mute/Unmute input and output channels. When an input channel is muted , a red LED will be lit for indication

2.) Gain / Menu Keys - Selects the corresponding channel for the LCD menu display and is acknowledged by a green LED. The last modified menu will be displayed on the LCD. Linking multiple channel is accomplished by pressing and holding the first channel key then pushing the other desired channels. This eases programming for same parameters across multiple channels . Multiple inputs can be linked together and multiple outputs can be linked together. Inputs and outputs can be linked separately

3.) Peak Level LED - Indicates the current peak level of the signal : Signal (-42 dB), -6dB,-3dB,Over/Limit. The Input Over LED references to the devices maximum headroom. The output Limit LED references to the threshold of the limiter

4.) LCD - Shows all the necessary information to control the unit

5.) Rotary Thumb Wheel - Changes parameter data values. The wheel has travel velocity sensing which ease large incremental data modifications. For modifying delay and frequency (1 Hz resolution), pressing the speed key simultaneously will increment/decrement the data value by 100x

6.) Menu Control Keys - There are 6 menu keys

• <<Menu (Menu Down)
• Menu>> (Menu Up)
• <<Cursor (Cursor Down)
• Cursor>>(Cursor Up)
• Enter/Sys/Speed
• Exit

• <<Menu : Previous Menu
• Menu>> : Next Menu
• <<Cursor : Previous cursor position in the menu screen
• Cursor>> : Next cursor position in the menu screen
• Enter/Sys/Speed : Enter is used only in the System Menu to proceed with selected actions Sys enters the  System Menu from the main menu Speed modifies delay and frequency (1 Hz resolution mode) data values by 100 x
• Exit : Exit to the Main Menu

Rear Panel Features:

1.) Main Power - Connects via a standard IEC socket. A compatible power cord is supplied with the unit. The voltage input is eithr 115VAC or 230VAC and is clearly specified on the unit. Voltage requirement has to be stated upon ordering

2.) Main Fuse - T0.5A - 250V for 115VAC  and T0.25A -250V or 230 VAC

3.) Power Switch - Switches On/Off

4.) RS232 - a standard female DB9 socket for PC connection

5.) XLR input and outputs - separate 3-pin XLR connectors are provided for each audio input and output

All inputs and outputs are balanced:

• Pin 1 - ground (shield)
• Pin 2 - hot (+)
• Pin 3 - cold (-)
