Auditor
13
Front Panel/Connection
Headphone Connection
You can use all dynamic headphones from 20-600 ohms (connection
impedance). Connect your headphones to the standard 1/4" (TRS)
stereo jack plug on the front panel. Make sure that the plug is firmly
seated for a solid connection.
Pin wiring TRS jack:
Tip=left channel, ring=right channel, sleeve=ground.
Recommendations
Unplug the headphone when you switch off the Auditor. Otherwise
discharging residual voltages can cause beeping sounds. We did not
add a circuitry to avoid that phenomenon because it would compro-
mise 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 Auditor volume setting of a first headphone at a
much higher – even painful – level.
Warning
NEVER plug in a mono 1/4" jack (TS) to the headphone output. The use
of a mono 1/4" will lead to a short-circuit that will destroy the final
amplifier stage! Standard headphone connectors always have stereo
plugs, and thus a correct connection will be assured when you only
connect headphones directly. Double check that you use stereo 1/4"
TRS plugs when you connect headphones via patchbays or extension
cables etc.
