Recording and playing back audio through USB
TO PLAYBACK AUDIO
1. Connect your computer to the mixer with a USB cable. Your
computer should see the mixer as a device labeled "Samsung
UC Audio".
2. Select the mixer to playback audio from your system
control panel.
3. Playback audio from your application.
4. Make sure the CTRM/MAIN button is down near the Jacks that
say CTRL RM OUT.
5. The audio is routing to the main outputs through Aux inputs,
which means the volume control is controlled by the main fader
if the "To Mix" button is depressed (next to the RCA jacks for
AUX). The same case for Control Room.
• Are the Gain and Level knobs turned up?
• Is the Main Mix fader turned up?
• Is the 2TK to Mix, 2TK to Phones, or Aux to Phones button
pressed in?
• If the mic needs phantom power, is the PHANTOM POWER
turned on? (Try it if you aren't sure.)
• Try a different microphone cable and/or microphone.
• Check the power connections, your power strip, extension
cords, etc.
You can hear everything, but it's very noisy.
• Are all of the level controls turned up very high? Try turning
those down and the gain controls up.
• Turn down the FX return. If that was the problem, try sending
more signal to the effects by turning all of the Aux knobs up.
• Try turning down channels one at a time. If there is one channel
that is contributing most of the noise, try fixing that at the
source.
You can see level on the meters, but can't hear anything through
the control room speakers.
• Is the Aux to Phones/Control Room or 2TK to Phones/Control
Room button pressed in?
• Are the monitors switched on?
• If only one output is working, try switching the left and right
outputs. If the same channel isn't working, the problem is with
the speaker.
You turned up the FX Return knob, but can't hear the effects.
• Are you sending enough level to light the Signal LED next to the
preset knob? If not then turn up the Aux knob(s).
•Are you listening to the Aux to Phones/Control Room by mistake?
•Try a different Preset or turn the Variable knob.
TO RECORD AUDIO
1. Connect your computer to the mixer with a USB cable. Your
computer should see the mixer as a device labeled "Samsung
UC Audio".
2. Select the mixer playback and record audio from your system
control panel.
3. Setup your mixer to have audio coming in as you normally would.
4. Start up your DAW application on your computer.
5. Make sure your DAW application is setup to receive audio from
the "Samsung UC Audio" (L1402FX-USB mixer)
6. Create an audio track on your mixer and enable it to record. To
avoid a feedback you can either switch the "To Mix" button to
be in the up position or disable the monitoring function in your
DAW program on the track you are recording to.
7. Perform your audio on the mixer and record the track on your
DAW application.
8. After recording you can play back the track from your computer
to the mixer to hear the playback. Be sure to turn on the
"To Mix" or "To Phones (CTRL ROOM)" button to hear the
audio playback.
