USING THE KNOB
AND THE TOUCH SENSOR

Turn the knob right: Volume Up
Turn the knob left: Volume Down

Touch sensor:

the small silver metal hemisphere on the left side of the

front plate. In order to reach certain functions you will need to combine
short (•) and long (

) touches.

Here you can find the combinations:

• next input (after last input comes input 1 again)

mute / un-mute

night mode activation/deactivation. After activation a dim dash will be

displayed in night mode. Deactivate the night mode with one short and
one long touch again on the sensor

sleep mode / wake up from sleep state

Personalisation possibilities:

• • • You can choose between two display brightness. They alternate with
every 3 clicks between the brighter and dimmer state

• •

switch between ‘L’ - low sensitivity and ‘H’ - high sensitivity of the

optical encoder. In high sensitivity mode adjust volume carefully and

do

not spin the volume control knob.

Important note:

If you bought your icOn 4PRO with the optional AV pass-through function
enabled for a particular input, on the output the input signal will appear
without attenuation (full volume, 0 dB) and you will see 0 (dB) on the
display.

In AV pass-through state every function (volume adjustment,

mute, balance) is disabled , only input change is possible to finish the AV
pass-through mode and listening normally from the other inputs. Please
be careful with the AV pass function, because using it in a wrong way you
can destroy your loudspeakers. If you don’t understand fully how does it
work - do not enable this function.
