❏ 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 are balanced. (1=GND, 2=HOT, 3=COLD)
* In these specifications, 0 dBu = 0.775 Vrms.
* All input AD converters are 24-bit linear, 128-times oversampling.
* +48V DC (phantom power) is supplied to INPUT XLR type connectors via each individual software controlled switch.
❏ Analog Output Characteristics
*1. XLR-3-32 type connectors are balanced. (1=GND, 2=HOT, 3=COLD)
*2. PHONES OUT 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 10dB lowered from Max.
* In these specifications, 0 dBu = 0.775 Vrms.
* All output DA converters are 24-bit, 128-times oversampling.
