This output is situated on the rear panel and
equipped with a TRS type socket. It is located
in parallel to the unbalanced inputs and
marked as "STEREO LINE OUT". Here the

THE AMPLIFIERS
Each module is equipped with two independent
stereo amplifiers. They are optimized to
operate headphones with lowest noise and
lowest distortions. They are long-term short-
circuit proteced and temperature monitored.
The detection of clipping or high temperature is
signalised by the red "CLIP/TEMP"-LED above
the respective volume control.
