PROBLEMS

SOLUTIONS

My audio signal is not appearing at the Stereo Master.

Have you pushed the white ´ON´ button for that channel?

.

Still no audio signal at the Stereo Master.

 

You need to increase the inner grey knob for more 
channel volume.

 

Yet still no signal arriving at the Stereo Master.

 

You might need to increase the volume on the blue 
Subgroup knob.

 

Even still, no signal arriving at the Stereo Master.

 

Have you pushed the white ´ON´ button for that 
Subgroup?

 

Even after checking all of that, the signal still isn´t arriving 
at the Stereo Master.

 

Make  sure  you  haven´t  pushed  an  INS  (Insert)  button 
without  having  anything  inserted  or  the  without  the 
patchbay

 

 being ´normalled´.

 

I´m only receiving audio on the ´Left´ side of the Stereo 
Master.

 

Check to see if the outer ring ´PAN´ control has been set 
to the extreme left side.

 

 

     

 

There  is  a  center  detent  to  assure  equal  signal  to  both 
sides.

 

There is no signal at all appearing at the Stereo Master.

 

Double check your cables and connections.

 

I´d like to get a Direct Out from each channel.

 

 Is it 

possible?

 

Yes, of course.

 

 Just tap the INSERT SEND signal, which 

is always active.

 

 This goes for Channels as well as 

Subgroups and Stereo Master.

 

I´d like to have a 12 channel bus for my drums.

 

 How 

could I configure it?

 

Just use the first 8 channels, sent to their Subgroup 1&2.

 

 

Take the output from Subgroup 1&2 and send it to 
channels 9&10.

 

 Then at the Subgroup 3&4 you will have 

channels 1-8 and channels 11-16.

 

 So that would allow 

you a drum bus of up to 14 channels.

 

I don´t want my AUX(FX) RETURNS hard panned Left or 
Right.  Is there another way to configure my setup to have 
more control over their position in the stereo MASTER 
Output?

Yes, by simply routing them to Channel Inputs you can 
position them anywhere in the stereo field.  

Just remember not to also send to the AUXs on those 
channels as it will produce feedback loop.
