*1. Sensitivity is the lowest level that will produce an output of +4dBu (1.23V) or the nominal output level when the unit is set to maximum gain.
(all faders and level controls are maximum position.)
*2. XLR-3-31 type connectors are balanced. (1= GND, 2= HOT, 3= COLD)
*3. In these specifications, 0dBu= 0.775 Vrms.
*4. All input AD converters are 24bit linear, 128times oversampling.
*5. +48V DC ( phantom power ) is supplied to OMNI IN (1-8) and TALKBACK XLR type connectors via each individual software controlled switches.
