442/442N User Guide and Technical Information

Headphone Peak LED

Like the Channel Peak LEDs, the headphone circuit has an indicator for peak overload. This LED is very use-
ful, since headphones can often overload before the mixer overloads. Monitoring without a visual indication of
headphone clipping could mislead the operator into thinking that the output or return feeds are distorted. The
Headphone Peak LED also doubles as a clip indicator for the stereo Return A and Return B signals. If any of the
Return signals clip (after the Return gain stage), the Headphone Peak LED illuminates.

Headphone Monitoring

The 442 can drive headphones to dangerously high volumes. Turn down the headphone gain control before selecting a
headphone source to prevent accidental signal extremes.

Headphone Source Selection

The rotary headphone source switch sets the audio source sent to headphones. The selections available are:
Off no signal
L left output only to both ears
R right output only to both ears
M summed (mono) left and right to both ears
ST stereo - left output to left ear and right output to right ear
A stereo Return A to headphones
B stereo Return B to headphones
A|B Return A (summed) to left ear, and Return B (summed) to right ear
MS L decoded MS Left to both ears
MS R decoded MS Right to both ears
MS ST decoded MS Stereo to headphones

Headphone Gain

Headphone gain is controlled by a pop up knob to remove it from the mixing surface.

Return A and B

The Return monitor switch has two positions, A and B. When switched to the A position, Return A audio is sent
to the headphones, taking precedence over the Headphone Source selection. Similarly, when toggled to the B
position, Return B audio is sent to the headphones. This switch can change assignments performed in the Setup
Menu.
