FRONT AND REAR CONNECTIVITY

 

Analogue Channel Inputs

• 2x Mic / Line / Instrument inputs on the rear panel (Inputs 1 and 2). Switches automatically between Mic (XLR) and Line (TRS). Instrument selected via front panel buttons
• 6x Mic / Line inputs on the rear panel. Switches automatically between Mic (XLR) and Line (TRS)

 

Analogue Channel Outputs

• 8x Balanced 1/4" TRS Jack on the rear panel
• Switching to enable monitoring of A/D inputs or ADAT inputs with ADDA switch on front panel

 

Digital I/O

• 2x ADAT Lightpipe (TOSLINK) inputs. Provides 8 channels at 44.1 and 48kHz (please note that in this mode, only ADAT input 1 is active, allowing for a total of 8 ADAT input channels at 44.1 / 48kHz). Provide 4 channels per port (8 total) at 88.2 and 96kHz (S-MUX)
