The desired output mode is selected by rotating the encoder knob: “DUAL SINGLE-
END” or “BALANCED”.
To confirm the selected output mode, push the encoder knob: the output mode will
be set and the unit will revert to “idle” status.
Optinally, if the user changes her/his minds and goes for keeping the output mode
previously set, she/he only needs to push the button to the left of the front panel
(Figure 1, 1) or avoid doing any other action on the unit. As a result, after a few
seconds, the MARLEY automatically reverts to its “idle” status without changing the
output mode.
6.6. Volume Display Mode Selection
The MARLEY’s volume levels may be displayed in two different fashions: deciBels or in
steps.
In the former, the highest volume is represented by 0dB, while negative figures with
increasing magnitude indicate increasingly lower volume. E.g., -15dB is lower volume
than -20dB.
In the latter, the highest volume is represented by 78, while positive figures with
decreasing magnitude indicate increasingly lower volume. E.g., 40 indicates higher
volume than 30.
To choose the volume display mode, it is necessary to push the encoder knob four
times in balanced mode or five times in dual single-ended mode: The volume mode
display selection feature is then accessed as shown in Figure 10.
