EURORACK UB1002FX/UB1202FX

This illustration shows a typical arrangement for a live setup. Two vocal microphones and the line outputs of a guitar and a bass amplifier are connected to the mono channels of the UB1202FX. A keyboard and a drum computer are connected to the stereo channels. The power amplifier in your sound system is connected to the main outputs; equipment such as compressors, equalizers or crossovers are located between the mixer and the amp in the signal path. If you wish to make a live recording, you can connect your recording equipment (in this case, a minidisk recorder) to the CD/tape outputs. A CD player that is playing during intermissions is connected via the CD/tape inputs. If you connect a recorder/player combo (e. g. a tape deck recorder), the CD/TAPE TO MIX switch should not be pressed during a recording because this way the signal intended for recording would be directly re-routed back to the mixing console, and then back to the recorder... this would cause a feedback loop as soon as you hit the record button. A loud, unpleasant, even painful sound would result.

If you are using an external effects processor (wired as shown in the illustration), please make sure that the FX SEND control in channel 11/12 is turned all the way down counterclockwise to avoid creating a feedback loop.

4.INSTALLATION

4.1Mains 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.

4.2 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 CD/tape inputs and outputs.

You can, of course, also connect unbalanced equipment 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.
