❏ 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 and TALKBACK XLR type connectors via each individual software con-
trolled switches.
❏ Analog Output Characteristics
*1.XLR-3-32 type connectors are balanced. (1=GND, 2=HOT, 3=COLD)
*2.PHONES stereo phone jack is unbalanced. (Tip=LEFT, Ring=RIGHT, Sleeve=GND)
*3.There are switches inside the body to preset the maximum output level.
*4.The position of the level control is 10 dB lowered from Max.
* In these specifications, 0 dBu = 0.775 Vrms.
* All output DA converters are 24 bit, 128 times oversampling.
❏ Digital Output Characteristics
*1.The channel status of 2TR OUT DIGITAL is described on page 267.
*2.XLR-3-32 type connectors are balanced. (1=GND, 2=HOT, 3=COLD)
