Behringer UB502 User Manual

EURORACK

UB502/UB802/UB1002/UB1202

+48 V (UB802/UB1002/UB1202 only)

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 recorders 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.
