1 | USB input (stereo)
USB port (type B) for linking a computer to the USB port. Normally this requires
no driver setup since the Linear USB II is recognised as an external audio device.
If the USB port receives no audio signal, the amplifier will automatically switch
to the analog input.
2 – 3 | Line input (stereo)
The RCA sockets of the line-level input are used to connect your analogue signal
source. This may be e. g. a tuner, a media player or the output of a phono
preamp. The socket with the red ring stands for the right line input, the socket
with the black ring for the left line input.

CAUTION!
NEVER connect signal sources to both inputs at the same time!
4 – 5 | Pre-out (stereo)
The RCA sockets of the pre-out can be used to connect all devices with a line
input, for instance a power amplifier, active loudspeaker or receiver. The socket
with the red ring stands for the right pre-out, the socket with the black ring for
the left pre-out.
6 | Mains switch
Use the mains switch to turn the Linear USB II on and off.
7 | Fuse
Fuse holder for a safety fuse (see technical specifications p. 50). Only fuses with
identical ratings must be used.
8 | Mains connection
Power inlet of the device to be used with the supplied power cord or a cable
with the same plug type. The Linear USB II must only be operated on the mains
voltage which the unit has been designed for. This can be read on the type label
on the bottom side of the device.
