// Solo
The SOLO channel is PFL
(pre-fade listening), that means you
listen to the sound going into this
specic channel before the mixer’s
fader takes effect, giving you the
original signal independent from
what is set in the mixer. Send the SOLO signal to your speaker
or headphone. This does not affect the signal sent to the other
outputs/mixes.
Set solo output level
Select hardware output
// Select Mix
In general, a mix combines multiple sound sources into one
or more output channels. In the process, a sound source’s
volume level and dynamics (Ducker FX) are set according
to your personal preference or application.
You can create two independent mixes, route and send them
to different outputs.
Mix A & B are available as inputs in audio applications
or can be selected as a source for hardware outputs
and virtual inputs.
MIX A (green color scheme) – Click to select Mix A. Green
color scheme indicates Mix A is active - use the fader to adjust
the volume.
MIX B (blue color scheme) – Click to select Mix B. Blue color
scheme indicates Mix B is active - use the fader to adjust
the volume.
Please note that the sources of the two mixes do not differ,
both mixes are sharing the same sources. They differ only
in the set levels of the different channels.

// Troubleshooting
I cannot hear anything!
Are you using a condenser microphone? Turn on 48V
phantom power.
Did you connect your speakers/headphones to the correct
output?
Use either the headphone output on the front or the monitor
speaker outputs on the back of the STREAM 4x5 to listen
to your audio.
Check the output volume and make sure that the output
is not muted.
Check all faders and mute buttons in the Lewitt Control
Center 2.0.
Did you set up your operating system to use the
STREAM 4x5 as the default audio input and output device?
Did you install LEWITT CONTROL CENTER 2.0 (Windows
only!)?
Can you see the STREAM 4x5 in the Control Panel device
list? If not, install the driver and/or try a different USB port.
A restart after installation can also solve the problem
in some cases.
The device can only be used on the integrated USB ports
of your computer or on an active hub. USB hubs without own
power supply are not suitable for this device. Always try an
integrated USB port if the device does not operate properly.
Can you hear playback but not the input signal or vice versa?
Check your hardware input fader setting in the CONTROL
CENTER 2.0.
