Elements at the rear side
1. Line input (Stereo)
RCA connectors for the source you want to hear with the Black Cube Linear
2. Line output (Stereo)
RCA connectors for the connection of your power amplifier or active
loudspeakers. Depending on which headphone output you are using on the
front side of the unit the signal is either fed through the Black Cube Linear to
the line output or muted. The RCA jacks are connected in parallel to the
Black Cube Linear’s output stage and not just passively connected to the
input connectors so that you benefit greatly when you use the unit as single
source preamp.
3. Power switch
This switch separates the primary coil of the power supply transformer from
the mains voltage. There is no stand by mode.
4. Fuse holder
Fuse holder for the primary fuse. In case of replacement you must use the
same type (100V – 120V AC: 630mA slow or T; 200V – 240V AC 315mA
slow or T). If there is a mechanical noise (rattle) when you move the unit
the Black Cube Linear is equipped with a spare fuse which is also placed in
the fuse holder.
5. Mains connector
IEC receptable for the connection to mains voltage. Please connect the
power cord here. You must make sure that you connect the Black Cube
Linear to the appropriate mains voltage. The mains voltage and fuse type
needed are both printed on a sticker underneath the unit.
