Applications
This compact audio mixer with USB interface and DSP effect unit is suitable for universal
applications, e.g. for audio recording with a the computer. It has four input channels, i.e. 2 x mono,
2 x stereo, for connecting microphones (also phantom-powered) and other audio sources with line
signal level ( e.g. musical instruments, players). In addition, there are connections for recording
and headphones are provided. The mixed stereo signal is sent via ¼-inch jacks and the USB jack.
The USB jack can be used at the same time as an input for transferring audio data from the
computer to the mixer.
The power connection is made via the supplied AC power adapter.
Setting into Operation
Prior to powering up the unit, the output controls MONITOR/ PHONES and MAIN MIX should be
turned back to “0”.
1. As audio sources, microphones and/or audio sources with line signal level (e.g. effect units,
musical instruments, players) can be connected to the four input channels.
Mono channels CH1 and CH2:
Combo XLR/¼-inch jack are available as inputs.
Connect microphones to the balanced XLR jack.
For phantom-powered microphones it is possible to activate a 48V phantom power for both XLR
jacks together with switch PHANOM POWER. When activated (switch position
Ⅰ
=on) the
indication PHANTOM PWR +48V lights up during operation.
Caution! Do not connect a microphone with unbalanced output via XLR plug; it may be
damaged by the phantom power. To prevent switching noise, only activate or deactivate
the phantom power .
Connect mono sources with line level to the unbalanced ¼-inch jacks. It is also possible to directly
connect musical instruments with high impedance ( electric guitar, electric bass) to these jacks: in
this case engage the impedance switch for that channel.
Stereo channels CH3/4 and CH5/6:
Stereo sources with line level may be connected to the ¼-inch jack of channel CH3/4 and to
the RCA jacks of channel CH5/6 (L=left channel, R= right channel). The jacks of channel
CH3/4 are balanced, however, it is also possible to connect units with an unbalanced output.
