Master volume
The master volume is controlled by turning the large volume wheel. The green num-
bers on the left side of the wheel will change as you turn the wheel - this is your

and on the Main Display. Volume Level display shows master level in relative
numbers with 99.9 corresponding to the maximum level and 0.0 corresponding to the
minimum level. Main Display shows master level in dB’s with 0 dB corresponding to
the maximum level and -99.9 dB corresponding to the minimum level. The wheel
sensitivity, maximum volume and other settings can be found in the “OPT” menu.
S-2150 X master volume can be controlled only by the supplied remote control. M/S-
2150 X master volume can be controlled via RS232 connection.
Mute
Use the “MUTE” button to mute or un-mute during playback. The master level indica-
tor will switch to “--” in Mute mode. You can still adjust the master volume while the
unit is in Mute mode - the master level indicator on the Main Display will show
current master level in dB’s.
