Input/output characteristics
ANALOG INPUT CHARACTERISTICS
*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.
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. In these specifications, 0dBu= 0.775 Vrms.
*4. All output DA converters are 24bit, 128times oversampling.
*5. There are switches inside the body to preset the maximum output level.
*6. The position of the level control is 10dB lowered from Max.
DIGITAL INPUT & OUTPUT CHARACTERISTICS
DIGITAL OUTPUT CHARACTERISTICS
*1. XLR-3-32 type connectors are balanced. (1= GND, 2= HOT, 3= COLD)
I/O SLOT (1-3) CHARACTERISTICS
Each I/O Slot accepts a mini-YGDAI card. Only Slot1 has a serial interface.
CONTROL I/O CHARACTERISTICS
*1. Input pin: TTL level, w/ internal pull-up (47k
Ω
)
Output pin: Open drain output (Vmax=12V, maximum sink current/pin=75mA)
Power supply pin: Output voltage Vp=5V, Max. output current Imax=300mA
*2. 4pin= +12V, 3pin= GND, Lamp rating 5W. Voltage control by software.
