7 EURORACK UB1202/UB1002/UB802/UB502 User Manual 2.2 Stereo channels 2.2.1 Stereo line inputs Fig. 2.4: Stereo line inputs LINE IN Each stereo channel has two balanced line level inputs on 1/4" jacks for left and right channels. If only the jack marked "L" (left) is used, the channel operates in mono. The stereo channels are designed to handle typical line level signals. Both inputs will also accept unbalanced jacks. 2.2.2 Equalizer stereo channels (UB802) The EURORACK UB802 features a stereo 3-band EQ in each stereo channel. The filter characteristics and cut-off frequencies are the same as those in the mono channels. BAL The BAL(ANCE) control determines the levels of left and right input signals relative to each other before both signals are then routed to the main stereo mix bus. If a channel is operated in mono via the left line input, this control has the same function as the PAN control used in the mono channels. LEVEL The LEVEL control determines the volume of the channel being sent to the main mix. +4/-10 The stereo inputs of the EURORACK UB1002 and UB1202 have an input sensitivity switch which selects between +4 dBu and -10 dBV. At -10 dBV (home-recording level), the input is more sensitive (requires less level to drive it) than at +4 dBu (studio level). 2.3 Connector panel and main section 2.3.1 Send/Return effects path Fig. 2.7: FX send/return connectors Fig. 2.5: The equalizer of the stereo input channels Fig. 2.8: FX send/return controls A stereo EQ is highly preferable to two mono equalizers. when working on a stereo signal, as two separate EQ's will usually produce an unwanted discrepancy between the left and right channels. 2.2.3 FX sends, balance and level adjustment Fig. 2.6: The FX send/balance/level controls STEREO AUX RETURN UB802 only: the STEREO AUX RETURN connectors are used to bring the output of the external effects device (whose input is derived from the aux sends) back into the console. You can instead use these connectors as additional inputs, but any effects device will then have to be brought back into the console via a normal stereo channel. This does, however, give you the ability to use the channel EQ on the effects return signal if you wish. ◊ When using a stereo channel as effects return path, the FX control of the relevant channel should generally be turned fully down to avoid undesirable feedback. If only the left connector is used, the AUX RETURN automatically operates in mono. Use the AUX RET(URN) control to determine how much of the effects signal is sent to the main mix. FX The FX sends of the stereo channels function similar to those of the mono channels. However, since the FX send buses are both mono, a mono sum is first taken from the stereo input before it is sent to the FX bus. The UB502 is not equipped with FX sends. FX SEND The FX SEND output (does not apply for UB502) should be connected to the input of an external effects unit. The post-fader FX signal you created using the input channel FX controls is sent to the effects unit via the FX SEND ouput. Use the FX SEND control of the main section to adjust the overall send level (UB1002 and UB1202 only).
