Because of the PSC M6 Mixer’s “retro” design, we have included the 12T 
microphone powering.  When set to 12T, 12 VDC is applied across pins 2 and 3.  
Pin 2 being positive and pin 3 being negative.  This polarity is know as “standard 
phase” and is the excepted A.E.S. standard.  Some older 12T microphones may 
have been wired as “Red Dot”.  This is the reverse polarity of standard phase 
and is still in use by a small percentage of 12T microphones world-wide.  Any 
“Red Dot” microphone can easily be converted to standard phase to bring it into 
the A.E.S standards of operation.  If you own 12T microphones wired “Red Dot” 
and do not wish to change their wiring, you can still operate them from the PSC 
M6 Mixer by using a simple phase cable or phase barrel.  PSC part numbers are 
as follows: 
FPSC0010C  Phase Reversal Barrel 
FPSC1017 

Phase Reversal Cable 

 

 

D. 

LOW CUT FILTERS 

 
Each input channel of the M6 Mixer is equipped with an active low cut (high 
pass) filter.  These filters are activated via the three way switches located near 
the adjacent channel fader knobs.  These filters will attenuate all frequencies 
below a preset frequency at a rate of 12dB per octave.  When set at “20Hz”, 
frequencies below 20 Hz are effectively rolled off with the mixer operating at full 
frequency response.  Optional low cut filter settings of 100Hz and 140Hz will roll 
off the frequencies below these figures at a rate of 12dB per octave (-3dB level at 
100Hz and 140Hz respectively.  Low cut filtering is important in location 
recording where wind noise can cause pre-amplifier overload.  This effect can be 
minimized by switching the low cut filter setting to either 100Hz or 140Hz cutoff.  
The low cut filter switches are located on the front of the M6 Mixer.  

 

E. 

CHANNEL GAIN    

 

In order to limit noise and increase headroom, the channel gain controls are 
located in the feedback path of the pre-amplifiers.  This provides continuously 
variable gain rather than just a decrease in channel output level when an 
overload situation occurs.  This results in increased headroom and lower chance 
of signal clipping (severe distortion).  These pots have an adjustment range of 
approximately 50dB. 
  

 

F.

 

CHANNEL PANS 

 

The new M6 Audio Mixer contains signal routing pan pots.  These pan pots are 
used to route the individual input channel’s signal to either the left or right 
summing buss or any combination in between. 

 

 

G. AUX 

SENDS: 

 

In addition to the two left and right summing busses, the M6 Mixer offers two 
additional auxiliary summing busses that can be used for aux sends to Comtek 
tm transmitters , Directors feeds, Video Assist audio feeds etc.  Each input 
channel contains two auxiliary send pots that control the level from that individual 
input channel to the auxiliary busses.
