INPUTS: 

 

A. BALANCED 

INPUTS 

 

The PSC M6 Audio Mixer provides six input channels utilizing female XLR 
connectors.  The studio grade input circuitry is transformer balanced for improved 
RF rejection and in-field practicality.  The XLR connectors are wired as follows: 
Pin 1 shield (ground), Pin 2 Audio high (in phase), Pin 3 Audio low (out of phase).  
Balanced wiring enables longer cable runs without the worry of excessive noise 
due to nearby electromagnetic and radio frequency interference.  These 
balanced inputs may be unbalanced if desired.  Either pin 2 or 3 may be tied to 
ground (pin 1) to unbalance the inputs of the M6 Mixer.  Note: The AES standard 
for unbalancing an XLR connector is to tie pin 3 to ground (pin 1). 

 
 
 

B. INPUT 

LEVELS 

 

The PSC M6 Mixer can accommodate a wide range in input levels.  Microphone 
levels of all types can be handled as well as line level signals.  The input range of 
the M6 Mixer is –60dBu to +4dBu.  Thus the M6 is compatible with all forms of 
consumer and professional audio equipment.  The input level switches are 
located on the front panel.  These input level switches provide for two level 
settings:  “M” Microphone level (0dB attenuation), and “L” Line level (50dB 
attenuation) This input level attenuation settings are used to correctly interface 
sources of varying levels to the M6’s preamplifiers.  Correct level matching 
ensures maximum headroom and lowest possible noise floor. 
 
 
 

C. MICROPHONE 

POWERING 

   

The M6 Mixer can accommodate the most popular microphones used today.  
The microphone powering switches are located directly below the input XLR 
connectors.  They can be switched to either Dynamic (D) or 48Phantom (48) or 
Tornador (12T).   
 
In the Dynamic position the mixer provides no microphone powering.  This 
position is used with Dynamic Microphones, Line Level inputs and when using 
Wireless Receivers. 
 
In the 48 Phantom Position the mixer provides 48 volts DC to pins 2 and 3 of the 
XLR connector.  48PH microphones or simplex powered microphones with a 
range of 9 to 52 volts or 12 to 52 volts may be powered by the M6 Mixer.  Pin 1 is 
shield to ground while pins 2 and 3 carry 48 volts DC.  The term “phantom” is 
derived from the fact that there is no voltage potential developed across pins 2 
and 3 thus a dynamic microphone transducer can be operated with 48PH turned 
on.  However, most portable wireless receivers will not operate with 48PH turned 
on.  We strongly recommend setting inputs to dynamic for use with all wireless 
systems.
