EURORACK UB502/UB802/UB1002/UB1202
The red +48 V LED lights up when phantom power is on. The
PHANTOM switch activates the phantom power supply on the
XLR connectors of all mono channels.

The blue POWER LED indicates that the console is powered on.
The high-precision 4-segment display accurately displays the
relevant signal level.
To correctly set the gains of the channels, first set the LEVEL
controls of the input channels to their center positions (0 dB).
Then use the GAIN controls to increase the input amplification
until signal peaks show 0 dB on the level meter.
When recording to digital recorders, the recorder’s peak meter
should not go into overload. While analog recorders can be
overloaded to some extent, creating only a certain amount of distortion
(which is common and often desirable), digital recorders distort
quickly when overloaded. In addition, digital distortion is not only
undesirable, but also renders your recording completely useless.

Connect the power supply to the 3-pin mains connector on the

3.2 Audio connections

You will need a large number of cables for different
applications. The illustrations below show how the connectors
should be wired. Be sure to use only high-grade cables.
Please use commercial RCA cables to connect the 2-track
inputs and outputs.
You can, of course, also connect unbalanced devices to the
balanced inputs/outputs. To do this, use either mono plugs or
stereo plugs with the ring and sleeve bridged (pins 1 and 3 in the
case of XLR connectors).
