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.
