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.
