ENGLISH 6 XENYX 1622FX/1832FX/2222FX/2442FX User Manual All Models Fig. 2.2: Equalizer of the input channels The upper (HIGH) and the lower (LOW) bands are shelving filters that increase or decrease all frequencies above or below their cut-off frequency. The cut-off frequencies of the upper and lower bands are 12 kHz and 80 Hz respectively. For the mid range, the console features a semi-parametric equalizer with a filter quality (Q) of 1 octave, tunable from 100 Hz to 8 kHz. Use the MID control to set the amount of boost or cut, and the FREQ control to determine the central frequency. 2.1.3 Monitor and effects busses (Aux sends) generally pre-fader, i.e. they operate independently of the position of the channel fader. PRE When the PRE switch is pressed down, the associated aux send is taken pre-fader. FX The aux send marked FX offers a direct route to the built-in effects processor and is therefore post-fader and post-mute. Please refer to chapter 4 "DIGITAL EFFECTS PROCESSOR" for detailed information. ◊ If you are using the built-in effects processor, make sure that STEREO AUX RETURN 3 has nothing plugged into it (2442FX and 2222FX), otherwise the internal effects return will be muted. This is not relevant if you use the FX OUT jack to drive an external effects device. ◊ 1622FX and 1832FX: On these consoles, the above note refers to the STEREO AUX RETURN 2 jacks as these models do not have a dedicated effect output. 2.1.4 Routing switch, PAN, SOLO and channel fader XENYX1622FX XENYX2442FX Fig. 2.3: Aux Send control MON and FX in the channel strips Monitor and effects busses (AUX sends) source their signals via a control from one or more channels and sum these signals to a so-called bus. This bus signal is sent to an aux send connector (for monitoring applications: MON OUT) and then routed, for example, to an active monitor speaker or external effects device. In the latter case, the effects return can then be brought back into the console via the aux return connectors. All monitor and effects busses are mono, are tapped into post EQ and offer amplification of up to +15 dB. Pre-fader/post-fader When using effects on a channel signal, it is usual to have the aux send post fader so that the balance between effect and dry signal stays constant even when the channel fader is altered. If this were not the case, the effects signal of the channel would remain audible even when the channel fader is turned all the way down. For monitoring, the aux sends are XENYX2442FX Fig. 2.4: The panorama and routing controls and the channel fader PAN The PAN control determines the position of the channel signal within the stereo image. When working with subgroups, you can use the PAN control to assign the signal to just one output, which gives you additional flexibility in recording situations. For example, when routing to subgroups 3 and 4, panning hard left will route the signal to group output 3 only, and panning hard right will route to group output 4 only. XENYX 1622FX/1832FX/2222FX/2442FX User Manual MUTE The MUTE switch breaks the signal path pre-channel fader, hence muting that channel in the main mix. The aux sends which are set to post-fader are likewise muted for that channel, while 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 GAIN 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 2442FX 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 7 Each stereo channel has two balanced line level inputs on jacks for left and right channels. Channels 9/10 and 11/12 on the 2442FX 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 GAIN control. Both jack inputs will also accept unbalanced connectors. LOW CUT and MIC GAIN These two control elements operate on the XLR connectors of the 2442FX, and are used to filter out frequencies below 75 Hz (LOW CUT) and to adjust microphone levels (MIC GAIN). LINE GAIN Use this control to adjust the line signal levels on channels 13-16 (2442FX only). LEVEL For level matching, the stereo inputs on the 1622FX, 1832FX and 2222FX 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). 2.2.2 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 XENYX2222FX XENYX2442FX Fig. 2.5: The various stereo channel inputs XENYX2442FX ENGLISH
