B: 

TO RDAT RECORDERS:  

 

The M4mkII Mixer can be interfaced to virtually any professional recorder via the 
standard XLR outputs.  In addition, you can use the 10 pin Hirose tm  connector 
if you desire to use the tape return function. 

 
 

C: 

TO WIRELESS MICROPHONES:  

 

The M4mkII Mixer will easily accept the output signal from virtually any wireless 
receiver.  It can accept microphone or line level signal via a simple switch setting.  
Please note that most wireless receivers are not compatible with 48PH mic 
power.  You should always set the M4mkII’s mic powering switch to “D” dynamic 
when using wireless receivers. 

 

The M4mkII Mixer can also be used to send audio signals to Betacams via 
wireless transmitters.  The use of transmitters is normally accomplished by 
connecting the M4mkII’s output XLR to the audio input of the specific transmitter.  
Many transmitter manufacturers supply application specific cables for this 
purpose.  The M4mkII Mixer has been designed to minimize RF interference 
through the use of output transformers and other RF filtering.  It is important to 
note that transmitter placement greatly affects transmit range and clarity.  For 
best results, transmitters should be mounted away from the mixers surface 
allowing un-impeaded RF radiation.  This can be accomplished by mounting the 
transmitters up and away from the mixer on the PortaBrace Strap.
