Headphone Connection
Connect headphones to the standard 1/4” (TRS) stereo plug on the
lower right front panel. The layout is: Tip =left channel, Ring = right
Channel, Sleeve = ground.
Make sure that the plug firmly seated for a solid connection.
Recommendations
Unplug the headphone when you switch off the Phonitor. Otherwise
discharging residual voltages can cause beeping sounds. We did not
add a circuitry to avoid that phenomenon as it would have compro-
mised sound quality.
Reduce volume level before you remove or plug in the headphone (or
when switching headphones). This excludes louder clicks and pops
reaching the ear. In addition, this can avoid unpleasant surprise that
follows when a headphone’s lower impedance suddenly reproduces an
otherwise acceptable Phonitor volume setting of a first headphone at a
much higher – even painful – level.
Warning
NEVER plug in a mono 1/4“ to the headphone output. The use of a
mono 1/4“ will lead to a short-circuit that will destroy the final ampli-
fier stage! Standard headphone connectors always have stereo plugs,
and thus a correct connection will be assured when you only connect
headphones directly.
