OPERATION 

 

Your new M4mkII Audio Mixer has been designed to operate under extreme field 
conditions.  The electronics have been designed to operate over a temperature 
range of -4 to 158 degrees Fahrenheit (-20 to +70C) less the affects on batteries.  
This in addition to the M4mkII’s ability to operate under high humidity conditions 
makes it perfect for harsh field conditions.

PORTA BRACE CASE 

 

Each PSC M4mkII Mixer is supplied with a custom-made Porta Brace case and 
shoulder strap.  This case includes sewn on mounting rings allowing you to 
mount Porta Brace accessory cases such as their RF Multi case.  These cases 
accommodate your wireless receivers.  You can call Porta Brace or any of their 
authorized dealers for the complete line of Porta Brace products. 

 

 

INTERFACING 

 
 

A. TO 

BETACAMS: 

 

 
The PSC M4mkII Mixer is especially designed for easy interfacing with all 
popular Betacam type cameras.  The M4MKII is equipped with a 10 pin Hirose tm 
connector on the left-hand side panel.  This all-inclusive connector provides both 
left and right balanced outputs and tape returns.  Pin Outs are as follows: 

 

Pin 1   

Left Output High 

Pin 2   

Left Output Low 

Pin 3   

Right Output High 

Pin 4   

Right Output Low 

Pin 5   

Left Tape Return 

Pin 6   

Tape Ground 

Pin 7   

Right Tape Return 

Pin 8   

Tape Ground 

Pin 9   

Ground 

Pin 10   

Ground 

 

The outputs are electrically the same as the XLR outputs on the right side of the 
mixer.  Thus, the output levels can be switched to the mic or live levels. 

 

PSC manufactures a selection of standard M4mkII Beta snake cables for use 
with the new M4mkII Mixer.  These cables are available in standard and camera 
breakaway versions from any authorized PSC dealer.  Part numbers are as 
follows:
