Headphone Connection

Connect headphones to the standard 1/4" (TRS) stereo jack plugs on 
the front panel. 

The layout is: Tip =left channel, Ring = right channel, Sleeve = ground.

Make sure that the plug is firmly seated  for a solid connection. 

Recommendations

Reduce volume level or press DIM before you remove or plug in a head-
phone  (or  when  switching  headphones).  This  excludes  louder  clicks 
and pops reaching the ear. In addition, this can avoid the unpleasant 
surprise that follows when a headphone’s lower impedance suddenly 
reproduces an otherwise acceptable 

2

Control 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.
