INTRODUCTION TO THE XONE:23 The Xone:23 is a high performance 2+2 channel VCA mixer designed around the latest analogue circuitry featuring microprocessor control of all signal routing. It is equipped with a version of the famous Xone filter system, a 3 band EQ Isolator, plus a send/return loop for external effects. The crossfader curve has two settings, suitable for either blending or beat matching, or a more aggressive curve for scratching.
INPUT CHANNEL CONTROLS Input level controls Adjust so that the average music level lights the 0 LED on the meter, with the beats lighting the +3 to +6 LED. Turn down if the +10 Red LED is illuminated. Each input has its own separate level control, so make sure to fully turn down (anticlockwise) the input you don’t want feeding into the mix. 3-Band full kill EQ Turn anti-clockwise to kill a frequency band or clockwise to boost.
MASTER CONTROLS Master output Level Sets the signal level to the main XLR mix output Monitor output Level Sets the signal level for the local monitor (booth) output Cue/Mix Control When set to Cue, nothing will be sent to the headphone output unless a channel Cue is activated. When set to Mix, the main mix will always be sent to the headphones. In the centre position the Cue signal and the main mix are summed together. Headphone level Sets the level of the headphone output.
MIC AND FILTER CONTROLS Microphone input Professional XLR balanced mic input. Use a low impedance dynamic hypercardioid Mic for best results. Microphone Level Adjusts the signal level of the mic input. If you are not using the mic, turn to minimum to prevent noise pick up. Microphone EQ 2 band EQ for adjusting the tonal balance of the DJ mic FX loop on switch Press this switch to activate the external effect loop.
REAR PANEL CONNECTIONS Line input Phono inputs Line input For connection to a line level device; (CD players etc) For connection to turntables only; this input has RIAA equalization for moving magnet cartridges. For connection to a line level device; (CD players etc) Note: An internal modification can convert these to Line (see page 14) Effects SND output Effects RTN input Connect this output to the input of an external effects unit. Connect this input to the output of an external effects unit.
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 provide two simultaneous filter types: high-pass, and low-pass. illuminated switch selects which type is active.
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.
SERVICING How to replace the crossfader If the crossfader is subject to a lot of use it will, in time wear out and need replacing. Intermittent or noisy operation is an indication that it is becoming worn. Using a propriety fader cleaner such as CaigLube might temporarily restore use, but DO NOT use on a new fader as it will wash away the factory applied grease.

FAULT FINDING No sound from mixer Check that the unit is powered on, and that an audio signal is connected to a channel input. Check that the Input level controls are turned clockwise at least to the centre position and that the music sources connected are in the correct inputs (Inputs 1 - 3 for turntables, Inputs 2 - 4 for CD players). Check that the EQ controls are in the centre position.
