Output audio level is controlled hrough the built-in web GUI. Volume control only affects the
4 / 8 Ω OUT
and
70V /
100V OUT
ports. Adjusting the audio output volume does not affect the
LINE OUT
port, as this port is a fixed-level
output. The
LINE OUT
port is designed to be connected to a pre-amp device.
