The [PHONES] jack on the front panel is designed for most stereo
headphones. The internal headphone amplifier outputs the maximum
power allowed by safety standards. The impedance and efficiency of
the headphones will determine the maximum volume available. Eight-
ohm headphones may be louder at a given setting than 150-ohm or
600-ohm headphones; however, there should be enough gain to drive
any dynamic headphone to reasonable levels, if the mixer is being run
properly.
Note that the PHONES/MONITOR level control on the front panel
affects both the headphone jack on the front panel and the [MONITOR
OUT] balanced jacks on the back panel.
Monitor Out
The [MONITOR OUT] jacks give you a signal that will be the same as
the MAIN OUT, as long as the front panel [MSTR/TAPE] switch is in
the "MSTR" position. The only difference is that the MONITOR OUT
signal is after the front panel PHONES level control. When that
control is up full, the MONITOR OUT jack will be 10 dB louder than the
MAIN OUT. The PHONES control may be lowered to the point where
the MONITOR OUT is almost at microphone level, low enough to be
patched into the microphone-level inputs of a camcorder or house PA
system. However, connect the monitor output to line level inputs
wherever possible.
