INTRODUCTION TO THE XONE:42 The Xone:42 is a high performance 12” analogue DJ mixer featuring four stereo dual input channels, a Mic/USB channel, 60mm linear VCA channel faders, an analogue VCF filter, and the new X:FX external effects loop with wet/dry control. This mixer is designed to seamlessly interface with current leading-edge DJ technology, and may be used by the widest range of DJs - from those who keep it in the bedroom, to regular performers and professionals.

MIC / USB INPUT CHANNEL USB 1 1 TO PC USB Connector USB (Universal Serial Bus) V1.1 is an external peripheral interface standard for data transmission. Xone:42 USB works at 12Mbps and provides two stereo uncompressed audio channels - one stereo up and one stereo down, or two mono up, two mono down. It is fully compatible with USB2. 2 3 The USB connection is used to send and receive audio data between the Xone:42 and a connected computer. Use a standard type A to B lead to connect to your computer.
MIC / USB INPUT CHANNEL USB 6 TO PC Channel Level Control The channel signal level can be adjusted from fully off to fully on. 7 Cue Switch Press the Cue switch to listen to the channel pre-fade signal in the headphones and view its level on the main meters. The red LED indicator next to the switch lights when selected. The Cue LED indicator in the monitor section also lights to warn that you are monitoring the channel signal rather than the main mix. Press the switch again to deselect cue.
PHONO / LINE INPUT CHANNELS 1 and 4 1 1 Channel Level Control This control has a range of off to +10dB. Use it to adjust the signal level of an audio source to give a nominal 0dB reading on the channel meter, with the peak level at or below 6dB. Turn LEVEL down if the +10 peak meter starts flashing. 2 2 3 Phono / Line Select Switch Selects either the RCA phono input or the alternative RCA stereo line input. In the up position PHONO is selected; when pressed, LINE is selected.
PHONO / LINE INPUT CHANNELS 1 and 4 6 Cue Switch Press the Cue switch to listen to the channel pre-fade signal in the headphones and see its level on the main meters. The LED indicator next to the switch lights when selected. The Cue LED indicator in the monitor section also lights to warn that you are monitoring the channel signal rather than the main mix. Press the switch to deselect cue. 7 Channel Meter Displays the channel signal level.
LINE / LINE INPUT CHANNELS 2 and 3 1 1 Allen & Heath Line A/B Select Switch Switches between the two RCA stereo line inputs available on Channels 2 and 3. In the up position LINE A is selected; when pressed, LINE B is selected.
FILTER SECTION 1 Pressing this button routes the X:FX return to the VCF filter, instead of directly into the main mix buss. The effected channel signal can then be filtered as well, allowing extra versatility and creativity to be brought into the mix. The blue LED lights to indicate that this function is selected. 1 2 2 5 Resonance Control This produces the classic analogue VCF sound by feeding some of the filter output back to its input.
FILTER SECTION 6 Frequency Sweep Control This control sets the –3dB cut-off frequency of the filter. It ranges from very low frequency (20Hz) to very high frequency (20kHz). NOTE: Both BPF and HPF filters are band limited to prevent them going above 10kHz. 7 VCF to Crossfader Press this switch to assign the filter to the crossfader. The crossfader can then be used instead of the FREQ VCF sweep control to create filter effects whilst crossfading.
HEADPHONE SECTION 1 1 Cue Active LED This LED lights to indicate that one of more of the input and / or mic channels is being monitored in the headphones. 2 2 Split Cue Switch Press this switch to change the way Cue operates. Normally, pressing a channel Cue switch overrides both left and right monitor program signals with the stereo cue signal. With the switch pressed, Cue overrides just the left channel leaving the program in the right channel.
MASTER SECTION 1 Mix / Monitor Meters The main meters follow the selected monitor source. The default display is the post master level, which is overridden with an input channel level if the channel cue switch is selected. 1 In split cue mode, the left master meter will display the cued channel signal level and the right master meter will display the mix level. The cued mix audio is pre level to prevent mismatch due to the position of the master level control.
CROSSFADER 2 3 1 1 Crossfader This lets you fade between signals routed to either side, typically to fade smoothly into a new music track or to creatively layer sounds when scratch or cut mixing. The crossfader is a VCA controller which affects the level of signals routed via the filters. Make sure the toggle switches on the channels you wish to fade are set to X or Y as appropriate. Please contact your Allen and Heath approved service centre for crossfader service or replacement.

USB CONNECTION The USB interface on the Xone:42 allows connection to a computer for recording, playback, and software-based effects. Remember to always use good quality RCA phono cables to route music signal between devices - sound quality will only be as good as the weakest component in the signal path. USB for Effects Connect the X:FX Send to USB In on the left side on the Xone:42’s rear panel using RCA phono cables.
FILTER REFERENCE The VCF Filters A voltage controlled filter is an audio filter where the cut-off frequency is altered by a DC control voltage rather than a variable resistor. This produces a much wider operating range and more control over the filter response to create unlimited combinations of tonal effect. Filter Type Select The filters are ‘state variable’. This means that they provide three simultaneous filter types: high-pass, band-pass and low-pass.
OPERATING LEVELS It is most important that the system level settings are correctly set. It is well known that many DJs push the level to maximum with meters peaking hard in the belief that they are getting the best from the system. THIS IS NOT THE CASE ! The best can only be achieved if the system levels are set within the normal operating range and not allowed to peak. Peaking simply results in signal distortion, not more volume.
EARTHING The connection to earth (ground) in an audio system is important for two reasons: SAFETY - To protect the operator from high voltage electric shock, and AUDIO PERFORMANCE - To minimise the effect of earth (ground) loops which result in audible hum and buzz, and to shield the audio signals from interference. For safety it is important that all equipment earths are connected to mains earth so that exposed metal parts are prevented from carrying high voltage which can injure or even kill the operator.
REPLACING THE CROSSFADER / FACE PLATE Replacing the Crossfader − Firstly, pull the crossfader cap vertically off the fader shaft and put it somewhere sensible. − Use a medium size cross-point screwdriver to undo and remove the two outer screws on the crossfader plate. − Carefully pull the crossfader assembly away from the front panel. − Unplug the cable from the old crossfader, and once the crossfader assembly is detached, unscrew the two inner screws to separate the fader from the plate.
