Operation
Headphone Monitor
Playback
The Playback control regulates the volume of the playback signal which is
passed to the musician. There are two methods of passing the mono play-
back signal: The first is to pass the music to both ear pieces of the head-
phone in which case ”Playback Input Left” must be connected. On the other
hand some musicians want to hear the playback signal through only one ear
piece so they can hear ”directly” with the other ear. In this instance connect
”Playback Input Right” and set the Volume control to Off.
Volume
The Volume control regulates the volume adjustment of the microphone,
instrument or line signal. The setting is independent to that of the Output
control or Mute switch, which means the volume in the headphones does
not alter although the output value of a modulation has changed.
With the Playback and Volume controls an individual mix for the head-
phones is achievable: it is advisable to ask the musician before recording starts
whether he can hear himself and the playback adequately.The best conditions
for good intonation, stemming from a relaxed working environment, prevail.
Another practical use of the headphone monitor module is to monitor the
signal quality directly to locate and eliminate possible interference rapidly.
Recommendation on using the Headphone Monitor: When working
with hard disc systems or digital mixing consoles latency may be present.
Flanging or phasing effects occur if the musician receives the monitor signal
with a time lag. It is therefore recommended, to obviate latency, that the
monitor signal passes directly from the headphone monitor to the head-
phones. It should be remembered that the recording signal has not been
picked up again by the playback signal because phase quenching can occur
when the same signal is mixed by both the Playback and Volume controls.
Phones
The Phones socket is provided for the connection of stereo headphones.The
high quality headphones amplifier is of low impedance and has low distor-
tion values so that all current types of headphones can be connected to
monitor the signals with highest possible audio fidelity.
