Input/Output Characteristics

Analog Input Characteristics

*1 Sensitivity is the lowest level that will produce an output of +4dB(1.23V) or the nominal output level when the unit is

set to maximum gain.(level control is maximum position.)

*2 XLR-3-31 type connectors are balanced. (1=GND, 2=HOT, 3=COLD)

*3 Phone jacks are balanced. (Tip=HOT, Ring=COLD, Sleeve=GND)

*4 In these specifications, when dBu represents are specific voltage, 0 dBu is referenced to 0.775 Vrms.

*5 AD converter is 24-bit linear,128-times oversampling @Fs=44.1, 48 kHz, 64-times oversampling @Fs=88.2, 96 kHz

Analog Output Characteristics

*1 XLR-3-32 type connectors are balanced. (1=GND, 2=HOT, 3=COLD)

*2 Phone jacks are balanced. (Tip=HOT, Ring=COLD, Sleeve=GND)

*3 In these specifications, when dBu represents are specific voltage, 0 dBu is referenced to 0.775 Vrms.

*4 DA converter is 24-bit, 128-times oversampling @Fs=44.1, 48 kHz, 64-times oversampling @Fs=88.2, 96 kHz

Digital Input Characteristics

*1 XLR-3-31 type connectors are balanced. (1=GND, 2=HOT, 3=COLD)

Digital Output Characteristics

*1 channel status of AES/EBU OUT

type: 2 audio channels

emphasis: NO

sampling frequency: depends on the internal configuration

*2 dither: word length 16 - 24-bit

*3 XLR-3-32 type connector is balanced. (1=GND, 2=HOT, 3=COLD)
