Operating the Device
In order to use this audio interface as efficiently as possible, please find an explanation of
the various controls and connectors below.
Hardware
HI-Z Switch
The Hi-Z switch for input 1 & 2 enables you connect an instrument with weak pre-
amplification to one of the inputs (an electric guitar is an example). This makes it possible
to record an instrument on one channel and vocals on the other.
Gain
The gain control is a sound amplifier that slightly amplifies input signals so they’re received
at an optimal level. A peak LED indicator is fitted above the gain control. If it lights up
green, a sufficient input signal is detected. If it lights up red, the input signal on the
corresponding channel is too high and may lead to an overdriven, distorted recording. Try
to avoid overdriven signals at all times – these have a large negative impact on sound
quality.
+48V Phantom Power Supply
+48V Phantom power is required for condenser studio microphones. This power supply
actively charges the microphone’s capsule with electrical current so audio signals are
processed and passed on as accurately as possible.
Phantom power is activated on both channels when enabled. In general, an internal
phantom power supply as featured in other devices (e.g. dynamic vocal microphones)
shouldn’t cause any damage.
The only exception concerns ribbon microphones.

you’d like to connect a ribbon microphone to the interface, please carefully read the
