Analog Output
u
Balanced Output - Balanced XLR analog output. Whenever a suitable receiver is available this
output should be the first choice.
XLR pinning as followed:
1 = Ground
2 = Non-inverted output, sometimes called “hot” or “+” input.
3 = Inverted output, sometimes called “cold” or “-” input.
v
RCA Output - Standard RCA output for analog signal..
Digital Connection
w
USB - USB 1.1 connection to computer, supports up to 48 kHz sample rate.
x
TOS-Link - Optical digital SP/DIF input, supports up to 96 kHz sampling frequency.
y
COAX - Coaxial digital SP/DIF input, supports up to 192 kHz sampling frequency.
z
AES/EBU - Balanced digital SP/DIF input, according to professional standard, supports
up to 192 kHz sampling frequency. Whenever a suitable source is available
this input should be the first choice.

USB Sound System Section
u
HEADPHONE - Use this terminal for connecting a headphone with a 3.5 mm plug. Audio signals via
USB can be listened to.
v
MIC - Microphone input terminal for connecting a microphone with a 3.5 mm plug.
By turning the level knob the microphone amplifier switches on - indicated by Mic-LED
- and can be adjusted for optimum level. The microphone signal will be send via USB
to a connected computer.
The microphone and headphone section is supported up to 48 kHz sample rate and
is for USB sound system use only. Microphone signals can be send to computer via
USB. Audio signals via USB from computer can be listened by headphone. A common
use for this section is internet telephony.
w
POWER - Power switch, turns the unit on / off. On is indicated by LED.
