[. . . ] EURORACK UB1204-PRO/UB1204FX-PRO Users Manual Version 1. 3 February 2006 EURORACK UB1204-PRO/UB1204FX-PRO IMPORTANT SAFETY INSTRUCTIONS DETAILED SAFETY INSTRUCTIONS: 1) Read these instructions. CAUTION: To reduce the risk of electric shock, do not remove the top cover (or the rear section). No user serviceable parts inside; refer servicing to qualified personnel. WARNING: To reduce the risk of fire or electric shock, do not expose this appliance to rain and moisture. [. . . ] The balance control determines the relative proportion between the left and right input signals before both signals are routed to the main stereo mix bus. The MUTE/ALT 3-4 switch, the MUTE-LED, the PEAK-LED, the SOLO switch and the channel fader function in the same way as the mono channels. 2. 3. 3 Stereo aux return connectors 2. 3 Connector panel and main section Whereas it was useful to trace the signal flow from top to bottom in order to gain an understanding of the channel strips, we now look at the mixing console from left to right. The signals are, so to speak, collected from the same point on each of the channel strips and then routed to the main section all together. Fig. 2. 8: Stereo aux return connectors STEREO AUX RETURN 1 The STEREO AUX RETURN 1 connectors generally serve as the return path for the effects mix generated using the postfader aux send. This is where you connect the output signal of the external effects device. If only the left connector is used, the AUX RETURN automatically operates in mono. 2. 3. 1 Aux sends 1 and 2 + You can also use these connectors as additional line inputs. Fig. 2. 6: AUX SEND controls of the main section A channel signal is routed to aux send bus 1 if the AUX 1 control is turned up on the corresponding channel. AUX SEND 1 (MON) The AUX SEND control MON acts as master control for aux send 1 and determines the level of the summed signal. AUX SEND 2 (FX) Similarly, the FX control (AUX SEND 2) determines the level for aux send 2. SOLO You can use the SOLO switch (UB1204FX-PRO only) to separately monitor the aux sends via the CONTROL ROOM/ PHONES outputs and check these with the level meters. STEREO AUX RETURN 2 The STEREO AUX RETURN 2 connectors serve as the return path for the effects mix generated using the FX control. If these connectors already function as additional inputs, you can route the effects signal back into the console via a different channel, with the added benefit that the channel EQ can be used to adjust the frequency response of the effects return signal. + + In this instance, the FX control of the channel being used as an effects return should be turned fully counterclockwise, otherwise feedback problems could occur!If you wish to use the internal effects processor, no connectors should be plugged into STEREO AUX RETURN 2. + If you want to monitor the signal of just one AUX bus, none of the other SOLO SWITCHES should be pressed and the MODE switch must be in the SOLO position (not pressed down). 2. CONTROL ELEMENTS AND CONNECTORS 7 EURORACK UB1204-PRO/UB1204FX-PRO 2. 3. 4 Stereo aux return + If you connect a compressor or a noise gate after the 2-track output, the faders will probably not be able to create a satisfactory fade-out effect. 2. 3. 6 Level meter and monitoring Fig. 2. 9: Stereo aux return controls STEREO AUX RETURN 1 STEREO AUX RETURN 1 is a stereo control which determines the level of the signal in the main mix. If STEREO AUX RETURN 1 is used as effects return, you can add the effects signal to any dry channel signal. + In this instance, the effects device should be set at 100% effect. Fig. 2. 11: Control room/phones section, level meter TAPE The TAPE switch routes the signal from the TAPE IN connectors to the level meter, the CONTROL ROOM OUT outputs and the PHONES connectorthis is a simple way to check recorded signals via monitor speakers or headphones. ALT 3-4 Similarly, the ALT 3-4 switch routes the signal from the Alt 3-4 bus to the same path for monitoring purposes. MAIN MIX The MAIN MIX switch sends the main mix signal to the abovementioned outputs and to the level meter. CTRL R & PHONES Use this control to set control room output level and headphones volume respectively. TAPE TO MAIN When the TAPE TO MAIN switch is depressed, the 2-track input is routed to the main mix and thus serves as an additional input for tape machines. You can also connect MIDI instruments or other signal sources here that do not require any further processing. At the same time, this switch disables the main mix to tape output link.
