EURORACK UB1204-PRO/UB1204FX-PRO 2.4.2 Voltage supply, phantom power and fuse 3. DIGITAL EFFECTS PROCESSOR Fig. 2.15: Voltage supply and fuse FUSE HOLDER The console is connected to the mains via the cable supplied which meets the required safety standards. Blown fuses must only be replaced by fuses of the same type and rating. IEC MAINS RECEPTACLE The mains connection is via a cable with IEC mains connector. An appropriate mains cable is supplied with the equipment. POWER Use the POWER switch to power up the mixing console. PHANTOM The PHANTOM switch activates the phantom power supply for the XLR connectors of the mono channels which is required to operate condenser microphones. The red +48 V LED lights up when phantom power is on. As a rule, dynamic microphones can still be used with phantom power switched on, provided that they are wired in a balanced configuration. In case of doubt, contact the microphone manufacturer! + After the phantom power supply has been switched on, do not connect microphones to the mixer (or the stagebox/wallbox). Connect the microphones before you switch phantom power on. In addition, the monitor/PA loudspeakers should be muted before activating the phantom power supply. After switching on, wait approx. one minute to allow the system to stabilize. + Caution! You must never use unbalanced XLR connectors (PIN 1 and 3 connected) on the MIC input connectors if you want to use the phantom power supply. SERIAL NUMBER Please note the important information on the serial number given in chapter 1.3.3. Fig. 3.1: Digital effects module (only UB1204FX-PRO) 24-BIT MULTI-EFFECTS PROCESSOR Here you can find a list of all presets stored in the multi-effects processor. This built-in effects module produces high-grade standard effects such as reverb, chorus, flanger, delay and various combination effects. The integrated effects module has the advantage of requiring no wiring. This way, the danger of creating ground loops or uneven signal levels is eliminated at the outset, completely simplifying the handling. You can route signals to the effects processor via aux send 2 in the channels and the aux send 2 master control. The built-in stereo effects processor has the advantage that it does not need to be cabled up. This eliminates any danger of hum or level mismatch right from the start providing straight-forward operation. These effect presets are designed to be added to dry signals. If you move the STEREO AUX RETURN FX control, you mix the channel signal (dry) and the effect signal. You can control the balance between the two signals with the channel fader and the STEREO AUX RETURN FX control. FX FOOTSW. Connect a standard foot switch to the foot switch connector; use this to switch the effects processor on and off. A dot at the bottom of the display indicates if the effects processor is muted via the foot switch. + On the following page, you will find an illustration showing how to connect your foot switch correctly. LEVEL The LED level meter on the effects module should display a sufficiently high level. Take care to ensure that the clip LED only lights up at peak levels. If it is lit constantly, you are overloading the effects processor and this could cause unpleasant distortion. The FX control (AUX SEND 2) determines the level that reaches the effects module. PROGRAM You can select the effect preset by turning the PROGRAM control. The display flashes the number of the current preset. To recall the selected preset, press the button; the flashing stops. You can also recall the selected preset with the foot switch. 10 3. DIGITAL EFFECTS PROCESSOR
