12 EURORACK UB1202FX/UB1002FX User Manual 4. Installation 4.1 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. 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. Balanced use with XLR connectors Balanced ¼" TRS connector strain relief clamp sleeve ring tip sleeve ground/shield ring cold (-ve) tip hot (+ve) For connection of balanced and unbalanced plugs, ring and sleeve have to be bridged at the stereo plug.
