EURORACK UB1622FX-PRO/UB1832FX-PRO/UB2222FX-PRO/UB2442FX-PRO the pre-fader monitor paths remain active irrespective of whether the channel is muted or not. MUTE LED The MUTE LED indicates a muted channel. CLIP-LED The CLIP-LED lights up when the input signal is driven too high. If this happens, back off the TRIM control and, if necessary, check the setting of the channel EQ. SOLO The SOLO switch is used to route the channel signal to the solo bus (Solo In Place) or to the PFL bus (Pre Fader Listen). This enables you to listen to a channel signal without affecting the main output signal. The signal you hear is taken either before the pan control (PFL, mono) or after the pan and channel fader (Solo, stereo) (cf. chap. 2.3.10 “Level meters and monitoring”). SUB (1-2 and 3-4) The SUB switch routes the signal to the corresponding subgroups. The UB2442FX-PRO has 4 subgroups (1-2 and 3-4). MAIN The MAIN switch routes the signal to the main mix bus. The channel fader determines the channel’s volume in the main mix (or submix). 2.2 Stereo channels 2.2.1 Channel inputs 2.2.2 Equalizer stereo channels The stereo channels contain a stereo EQ section. The cut-off frequencies of the high and low bands are 12 kHz and 80 Hz respectively, while the center frequencies of the high-mid and low-mid bands are 3 kHz and 500 Hz respectively. The HIGH and LOW controls have the same characteristics as the EQ in the mono channels. Both mid range bands are of the peak filter type. A stereo EQ is superior to two mono EQs on a stereo signal as two separate EQs will usually result in a discrepancy between left and right channels. 2.2.3 Aux sends stereo channels In principle, the aux sends of the stereo channels function the same way as those of the mono channels. As the aux sends are mono, the send from a stereo channel is first summed to mono before it reaches the aux bus. 2.2.4 Routing switch, solo and channel fader Fig. 2.6: Balance control and mute switch BAL The BAL(ANCE) control has a similar function to the PAN control in the mono channels. The balance control determines the levels of the left and right input signals relative to each other before both signals are routed to the left/right main mix bus (or odd/even subgroup). The remaining control elements in the stereo channels perform the same functions as their counterparts in the mono channels (MUTE switch, MUTE and CLIP LEDs, SOLO switch, SUB and MAIN switches and channel fader). 2.3 Interface panel and main section Where 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. 2.5: The various stereo channel inputs Each stereo channel has two balanced line level inputs on jacks for left and right channels. Channels 9/10 and 11/12 on the UB2442FX-PRO feature an additional XLR microphone jack with phantom power. If only the left jack (marked “L”) is used, the channel operates in mono. The stereo channels are designed to handle typical line level signals, and, depending on model, have a level switch (+4 dBu or -10 dBV) and/or a line TRIM control. Both jack inputs will also accept unbalanced connectors. LOW CUT and MIC TRIM These two control elements operate on the XLR connectors of the UB2442FX-PRO, and are used to filter out frequencies below 75 Hz (LOW CUT) and to adjust microphone levels (MIC TRIM). LINE TRIM Use this control to adjust the line signal levels on channels 13-16 (UB2442FX-PRO only). LEVEL For level matching, the stereo inputs on the UB1622FX-PRO, UB1832FX-PRO and UB2222FX-PRO have a LEVEL switch to select between +4 dBu and -10 dBV. At -10 dBV (homerecording level), the input is more sensitive than at +4 dBu (studio level). 2.3.1 MON control, aux sends 1, 2 and 3 (FX) Turning up the AUX 1 control in a channel routes the signal to the aux send bus 1. + As the UB1832FX-PRO is equipped with an additional monitor path, its first aux control in the channel strips is named MON. The console also has a dedicated master fader (MON SEND) for this aux path. AUX SEND 1, 2 and 4 The AUX SEND 1 control governs the master send level of the mix created by the individual channel AUX 1 sends. Likewise, the AUX SEND 2 contol is the master control for the aux 2 bus, and AUX SEND 4 controls the AUX 4 bus. 2. CONTROL ELEMENTS AND CONNECTORS 7
