When connecting an unbalanced output to a bal-
anced input, be sure that the signal high (hot) 
connections are wired to each other. The unbal-
anced ground (earth) connection should be wired 
to the low (cold) and the ground (earth) connec-
tions of the balanced input. If there are ground-loop 
problems, try disconnecting the unbalanced ground 
(earth) connection from the balanced input ground 
(earth) connection, leaving the unbalanced ground 
connected to the balanced input low (cold) con-
nection only.

In some cases, you may have to make up special 

adapters to interconnect your equipment. For example, 
you may need a balanced XLR female connected to an 
unbalanced 1/4" TS phone plug. Many common adapters 
can be found at your local electronics supply store.

The balanced-to-unbalanced connection has been 

anticipated in the wiring of Mackie jacks. A 1/4" TS plug 
inserted into a 1/4" TRS balanced input, for example, 
will automatically unbalance the input and make all the 
right connections. Conversely, a 1/4" TRS plug inserted 
into a 1/4" unbalanced input will automatically tie the 
ring (low or cold) to ground (earth).

TRS Send/Receive Insert Jacks

Mackie’s single-jack inserts are three-conductor 1/4" 

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

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.

this plug connects to one of the 
mixer’s Channel Insert jacks.

Using the Send Only on an Insert Jack

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

the fi rst click) into a Mackie 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’s signal at that 

point in the circuit without interrupting normal operation.

Note:

 Do not overload or short-circuit 

the signal you are tapping from the 
mixer. That will affect the internal 
signal.

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.

Direct out with no signal interruption to master.

Insert only to first “click.”

Mults and “Y”s

A mult or “Y” connector allows you to route one output 

to two or more inputs by simply providing parallel wir-
ing connections. You can make “Y”s and mults for the 
outputs of both unbalanced and balanced circuits.

Remember: 

Only mult or “Y” an 

output into several inputs. If you need 
to combine several outputs into one 
input, you must use a mixer, not a 
mult or a “Y.”
