alternative, after a few seconds past the encoder rotation the unit automatically
reverts to “idle” status.

6.2. Muting Toggle

The MARLEY is provided with a feature (muting) which allow for lowering the volume
20dB without touching the encoder knob. This feature is useful when user needs to
listen to another person for a moment, or while changing music programs in the
source, etc.

Muting is toggled by pushing the button to the left of the front panel (Figure 1, 1).
When muting is engaged, the word “MUTE” appears on the display (Figure 4).

In dual single-ended mode, muting affects both outputs.

WARNING: Carefully operate on volumes when muting is engaged: If volume is
raised too much and muting is disengaged, the resulting listening level could
be so high that damage to the headphone sets or to the listener’s ears may
occur.

6.3. Source Selection

The MARLEY is provided with two inputs, it is therefore possible to connect two
sources to it and select one for listening. To do this, it is necessary to push the
encoder once in balanced mode or twice in dual single-ended mode: the input
selection feature is then accessed as shown in Figure 7.
