EURORACK UB1202/UB1002/UB802/UB502 User Manual

+48 V
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.

◊

Please do not connect microphones to the mixer (or the
stagebox/wallbox) as long as the phantom power supply is
switched on. Connect the micro-phones before you switch on the
power supply. In addition, the monitor/PA loudspeakers should be
muted before you activate the phantom power supply. After switching
on, wait approx. one minute in order to allow system stabilization.

POWER
The blue POWER LED indicates that the console is powered on.

Level indicator
The high-precision 4-segment display accurately displays the relevant

signal level.
LEVEL SETTING: 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.

◊

The peak meters of your EURORACK display the level virtually
independent of frequency. A recording level of 0 dB is recommended
for all signal types.

3. Installation

3.1 Mains connection

AC POWER IN
Connect the power supply to the 3-pin mains connector on the rear of the

console. Use the AC adapter supplied to connect the console to the mains.

The adapter complies with all applicable safety standards.

◊

Please use only the power supply unit provided with the console.

◊

Never connect the EURORACK to the power supply unit while the latter
is connected to the mains! First connect the console to the power
supply unit, then connect the power supply unit to the mains.

◊

Please note that both the power supply unit and the mixing console
heat up considerably during operation. This is completely normal.

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).

◊

Caution! Never use unbalanced XLR connectors (PIN 1 and 3 connected)
on the MIC input connectors when using the phantom power supply.

For unbalanced use, pin 1 and pin 3

have to be bridged
