1 Applications
The USB-AUDIOBOX is designed as an audio
interface between audio sources, recorders and
a computer with USB 1.1 or USB 2.0 port. It al-
lows e. g. to transfer analog audio signals to a
PC, to process them there and to burn them on
CD (provided that the computer is equipped with
the corresponding hardware and software) or to
reproduce audio recordings stored on the PC.
The unit is provided with a headphone output to
monitor the input signals and the audio signals
coming from the computer. It is supplied with
power via the USB interface.

3 Connection
1) Connect a signal source with line output level
(e. g. CD player or mixer) to the jacks LINE IN
(2) [L = left channel, R = right channel]. For
connecting a microphone or a guitar, a corre-
sponding preamplifier will be required.
2) For amplification or for recording an audio sig-
nal coming from the computer, connect the
line input e. g. of a recorder, amplifier or mixer
to the jacks LINE OUT (1).
3) Connect the jack USB (3) to the USB
port of a computer. With the computer
switched on, the LED POWER ON (4) will
light up.
4) To monitor the input signal and the signal
from the computer, connect stereo head-
phones (recommended impedance ≥ 32 Ω)
with 3.5 mm plug to the jack MONITOR
(5).

4 Operation

1) Once the audio interface has been connected
to the computer in operation, the operating
system of the computer connected will rec-
ognize its audio connections as two USB
audio units (audio input and audio output).
If necessary, install the drivers required by
the operating system and restart the com-
puter.
2) Select the desired signal source for the head-
phones with the switch SOURCE (6):
LINE
the signal of the input LINE IN (2)
USB
the audio signal coming from the computer;
according to the setting of the computer or the
programs used, this signal may also contain
the input signals (possibly to be heard with
delay).
3) Adjust the desired headphone volume with
the control MONITOR LEVEL (7).
.
CAUTION Always adjust the headphones
to a reasonable volume.
Permanent high volumes may
damage your hearing.
