Reg. step 1: The factory setting of the input
sensitivity (Highlevel 11.3 Volts; RCA / Cinch

propriate for the most common radios. As soon
as the connected signal source provides an
maximum input voltage of 14 Volts – for ex-
ample, if a factory installed amplier is used
as signal source – all four internal jumpers has
to be repositioned to the “High Voltage Range”
(Highlevel 8 - 32 Volts; RCA / Cinch 2 - 8 Volts).
To get access to the jumpers the device has to
be opened. Therefore dismantle the side panel
where the USB input is located by removing the
