How to operate
Selecting a source
Select the desired source by pushing the but-
ton beside the name of the connected source.
A blue dot will light between the text and the
button to indicate the selected source. For ex-
ample to the right the CD input is selected.
The input selection can be toggled with the
remote control, please refer to the section
“Remote control”
Adjusting the listening level
In the middle of the DI 150 front panel you
will
fi
nd the large volume control knob. On the
outside parameter of the knob a small blue dot
lights up to indicate the level setting. Turn the
knob by hand to the desired level. The scale
goes from approx 8 o’clock minimum level to
approx. 4 o’clock as maximum output level.
The output level can also be adjusted by the
remote control, please refer to the section
“remote control”
Please note:
We have selected an expensive ALPS dual logarithmic potentiometer for setting the
listening level. To reduce noise, we have chosen a 1kOhm version. Such a potentiometer cannot make
the sound disappear completely, even when you turn it down to the lowest setting. If complete si-
lence is required, enable the Mute function described below.
Mute function
The DI 150 features a mute function that will
ef
fi
ciently mute the selected signal. Push the
“mute” button to activate the Mute function.
The blue dot indicating the selected source
is now replaced by a dot indicating the mute
function is enabled as shown below.
Push the Mute button again to disable the mute
function and return to the previously selected
source and level. For your comfort and the
safety of your equipment, please ensure before-
hand that the volume knob has not accidentally
been adjusted further towards the maximum out-
put setting before you disable the mute button.
The Mute function can also be enabled and
disabled by the remote control, please refer to
the section “remote control”.
