DESCRIPTION 

Mixer Mate is a Microphone and Monitor Controller that allows popular “live music” audio mixers to be used in a 
broadcast environment. Mixer Mate adds three important functions to the mixer: (a) it provides convenient On/Off 
control of up to four microphones, (b) it mutes the Monitor audio when a microphone is in use, and (c) it provides 
control of 

On The Air

 studio warning lights. 

 
INSTALLATION 

Mixer Mate utilizes the mixer’s “Mic Process Insert” facility to switch microphone audio on or off.  Up to four mics 
can be independently controlled via the unit’s front panel pushbuttons. Connect the mixer’s Process Insert circuit to 
Mixer Mate via the four ¼” TRS (tip-ring-sleeve) jacks on the rear panel. Wire the Mixer Mate TRS plugs as follows:  
TIP:  

 

From mixer’s mic preamp output 

RING:   

To mixer’s mic channel return input 

SLEEVE: 

To mixer ground 

 
In most cases, a simple TRS patchcord can be used to connect the mixer and the Mixer Mate together. 
 
Mixer Mate provides a Monitor Mute facility so that Monitor audio can be muted when selected microphones are in 
use.  Connect the Monitor output of the mixer to the Monitor Mute/IN jacks on the Mixer Mate (The top jack is left; 
the bottom jack is right.)  Connect the Monitor Mute/OUT jacks on Mixer Mate to the Line input of the monitor 
amplifier

.  Warning: Do not connect directly to the high-power speaker outputs of the monitor amplifier. 

 

Mixer Mate also provides a means of controlling “On The Air” studio warning lights, switching the lights on 
whenever any microphone is in use.  

Warning:  Do not connect 115 volt AC circuits directly to the Mixer Mate! 

The best way to control warning lights is with a Henry Engineering Superelay. The Mixer Mate interfaces to the 
Superelay via the 1/8” TRS mini-jack on the rear of the unit.  Wire an 1/8” plug as follows and connect to the 
Superelay CONTROL INPUT connector: 
TIP: 

 

To Superelay “12V” terminal 

RING:   

To Superelay “+ IN” terminal 

SLEEVE: 

To Superelay “G” terminal 

 
Note:  When connected as above, Mixer Mate is powered by the Superelay.  Do NOT connect any external power 
supply to the +12VDC jack on the Mixer Mate.  (The external power supply should be used only if the Mixer Mate is 
NOT used with a Superely.) 
 

MONITOR MUTE PROGRAMMING 

Mixer Mate can be programmed to mute the Monitor system when selected microphones are in use.  Select the 
mics that will activate the Monitor Mute function using the MON MUTE SELECT “dip” switches on the rear of the 
unit. There is a switch for each mic; if the switch is DOWN, the Monitor audio will mute when that microphone is on. 
 

OPERATION 

The microphones are turned on or off via the front panel pushbuttons.  The LED above each button will light to 
indicate that the mic is on. The Monitor system will mute whenever selected mics are on.  Tally lights will be active 
whenever any mic is on. Note that the mic on/off function will still operate even if the Mixer Mate is not powered-up.  
Power is required to activate the Monitor Mute and Tally light functions, as well as illuminate the front panel LEDs.
