LX8 & LX12 

OWNER’S MANUAL

A REAL-WORLD EXAMPLE USING THE LX12:

 

Tracking a Vocal and a Guitar simultaneously to a click track being generated by your DAW. 

1.  Within the DAW, initialize 2 separate mono tracks that will serve as destinations for the vocal and guitar signals coming from the mixer.  On the 

vocal channel, select the mixer’s R output, on the guitar channel, select the mixer’s L output.

2. Plug your vocal mic into XLR or TRS input of CH1 (activating the 48V Phantom Power switch if it is a condenser mic) 
3.  While watching the mixer’s CH1 clip indicator, sing into the microphone and set the CH1 GAIN control so that only the loudest input causes brief 

clipping. Then reduce the gain slightly. 

4.  While watching the input level meter of the DAW’s vocal channel, adjust the mixer’s CH1 LEVEL control to get an acceptable level feeding the 

DAW. The loudest input should fall just below clipping.

5. Then turn the CH1 PAN control all the way to the right

 6. Plug your guitar into CH 5|6 L/mono input and engage the Hi-Z button.
7.  While watching the CH 5|6 clip indicator LED, strum the guitar. When only the loudest input briefly triggers the clip LED, reduce the CH 5|6 GAIN 

control slightly.

8.  While watching the input level meters of the DAW’s guitar channel input, strum the guitar and bring up the mixer’s CH 5|6 LEVEL control until the 

loudest input falls just below clipping.

9. Now turn the Pan control on CH 5|6 all the way to the left 
10.  Your DAW or audio capture software can now receive the vocal channel audio and the guitar channel audio on 2 separate tracks. Keep in mind, 

if the microphone is in close proximity to the guitar, there will likely be some bleed of the guitar into the vocal channel. 

11. Now in your DAW set up a channel that can play a click or guide track at the desired tempo, but do not start playing it yet 
12. Set up your DAW’s audio output to the LX12 USB and on the mixer press the USB Routing to CH 9|10 button 
13. Set the HEADPHONE|CTRL RM SOURCE button to the MON position
14.  Make sure the CH 9|10 level control is turned all the way down to the left (counter-clockwise) and slowly turn up the MON level control on CH 9|10.
15.  Use the channel MON SEND CONTROLS to create a mix of the playback and live recording tracks. You will hear both the playback tracks and 

the signals you are recording in the Headphones and CTRL RM OUT output, but only the signals being sent to the MAIN mix will be recorded by 

the DAW 

16.  Now when you arm a channel and hit record in your DAW, the click or guide track audio will be sent to the LX12 for you to monitor in headphones 

or control room speakers, but your final captured performance will not include these signals. Only your performance will be captured via USB 

into your DAW.
