Analog Input Characteristics
*1. Sensitivity is the lowest level that will produce an output of +4 dBu (1.23 V) or the nominal output level when the unit is set to maximum gain. (all fad-
ers and level controls are maximum position.)
*2. XLR-3-31 type connectors with latch are balanced. (1=GND, 2=HOT, 3=COLD)
* In these specifications, 0 dBu = 0.775 Vrms.
* All input AD converters are 24bit linear, 128 times oversampling.
* +48V DC (phantom power) is supplied to INPUT (1-48 or 1-32), ST IN 1L-4R, OMNI IN 1-8 and TALKBACK XLR type connectors via each individual
software controlled switches.
