13 EURORACK UB1222FX-PRO User Manual 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 using the footswitch. 3.2 XPQ surround function The surround function can be enabled/disabled with the XPQ TO MAIN switch. This is a built-in effect that widens the stereo width, thus making the sound more lively and transparent. Use the SURROUND control to determine the intensity of this effect. 4. Installation 4.1 Rack mounting The packaging of your mixing console contains two 19" rack mount brackets which can be installed on the side panels of the console. Before you can attach the rack mount brackets to the mixing console, you need to remove the screws holding the left and right side panels. Use these screws to fasten the two brackets onto the console, being careful to note that each bracket fits a specific side. With the rack mount brackets installed, you can mount the mixing console in a commercially available 19" rack. Be sure to allow for proper air flow around the unit, and do not place the mixing console close to radiators or power amps, so as to avoid overheating. ◊ Only use the screws holding the mixing console side panels to fasten the 19" rack mounts. 4.2 Cable connections You will need a large number of cables for the various connections to and from the console. The following illustrations show the wiring of these cables. Be sure to use only high-grade cables. 4.2.1 Audio connections Please use commercial RCA cables to wire the 2-track inputs and outputs. You can, of course, also connect unbalanced devices to the balanced input/outputs. Use either mono plugs, or ensure that ring and sleeve are bridged inside the stereo plug (or pins 1 & 3 in the case of XLR connectors). ◊ Caution! You must never use unbalanced XLR connectors (pins 1 and 3 connected) on the MIC inputs if you intend to use the phantom power supply. 21 3 12 3 input output 1 = ground/shield 2 = hot (+ve) 3 = cold (-ve) For unbalanced use, pin 1 and pin 3 have to be bridged Fig. 4.2: XLR connections Unbalanced ¼" TS connector strain relief clamp sleeve tip sleeve (ground/shield) tip (signal) ¼" TS footswitch connector strain relief clamp sleeve tip sleeve pole 1/ground Fig. 4.3: 1/4" TS connector Balanced ¼" TRS connector strain relief clamp sleeve ring tip tip pole 2 The footswitch connects both poles momentarily Fig. 4.1: 1/4" TS footswitch connector 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.
