VLZ4 4•Bus

TRS Send/Receive Insert Jacks

Single-jack inserts are three- conductor, TRS-type 1⁄4" 

phone. They are unbalanced, but have both the mixer 
output (send) and the mixer input  (return) signals in 
one connector. See the illsutration below.

The sleeve is the common ground (earth) for both 

signals. The send from the mixer to the  external unit is 
carried on the tip, and the return from the unit to the 
mixer is on the ring.

Using the Send Only on an Insert Jack

If you insert a TS (mono) 1⁄4" plug only  partially (to 

the first click) into a VLZ4  insert jack, the plug will not 
activate the jack switch and will not open the insert 
loop in the  circuit (thereby allowing the channel signal 
to continue on its merry way through the mixer).

This allows you to tap out the channel or bus signal 

without interrupting normal operation.

If you push the 1⁄4" TS plug in to the second click, 

you will open the jack switch and create a  direct out, 
which does interrupt the signal in that channel. See the 
illustration below.

NOTE: Do not overload or short-circuit the signal you 

are tapping from the mixer. That will affect the internal 

signal.

Direct out with no signal interruption to master.

Insert only to first click.
