55.  CR/PH Only (Stereo Return 4)

Once again, the default for all the stereo  returns is to 

feed them directly into the main mix. You’ve just learned 
about the  optional  exceptions involving stereo return 3.

Stereo return 4 also has an optional exception: By 

engaging this switch, you will remove stereo  return 4’s 
stereo signal from the main mix and send it directly to 
the CR/phones source [42] matrix. It matters not if any 
of the source matrix switches are assigned, but it will be 
interrupted, as usual, if a solo [27] switch is engaged.

Let’s pretend you’re doing a live mix to a 2-track deck, 

a house PA, or both, and you want to play along to a 

click track. You could run the click track directly into 

the main mix, but you don’t want the mixdown deck 
and/or audience to hear it. By gum, this is the switch 
for you. Similarly, it can be used for voice-over tracks, 
narration, anything you want heard by the engineer and 
players but not by the audience and mixdown deck.

56.  Returns Solo and LED

This switch operates just like the channel solo [27] 

switches — engaging it sends signals to the control 
room, headphones, and meter display, and interrupts 
whatever happened to be there before you soloed. 

 

It follows the mode [44] switch setting as well. 

 

The only difference is that when you engage this 

 

returns solo switch, it sends all four stereo returns 

signals to the solo circuit.

Assume you want to solo the snare drum. Hit that 

channel’s solo switch, and you get the “dry” (no effects) 
snare only. That helps, but you want to hear it with the 

reverb you have patched into a stereo return. Leaving 

that channel’s solo switch engaged, also engage the 
returns solo switch, and now you’ll get the dry snare 

 

and its reverb. 

Since it is a global feature, you’ll also get the signals 

from all the other stereo returns, so there may be some 
sounds that you didn’t want to hear. If they offend your 
sensibilities, simply turn down the levels of the  stereo 
returns you don’t want to hear, or mute the channels 
feeding the unwanted signal to the effects device you 

 

do want to hear. 

Congratulations! You’ve just read about all the 

 

features of your 1642VLZ4. You’re probably ready for 

 

a cold one. Go ahead. The rest of the manual can wait.
