6 INTRODU CTION T O THE XONE:23 The Xone:23 is a high performance 2+2 cha nnel VCA mixer designed around the la test analogue circuitry featuring microprocessor control of all signal routing. It is equipped with a version of the famous Xone filter system, 3 band EQ, plus a send/return loop for external effects.
7 INPUT CHANNEL CONTROLS Input level controls Adjust so that the aver- age music level lig hts the 0 LED on the meter, with the beats lighting the +3 to +6 LED.
8 MASTER CONTROLS Master output Level Sets the signal level to the main XLR mix outp ut Monitor output Level Sets the signal level for th e local monitor (booth ) output Headphone level Sets the level of the head- phone outpu t.
9 MIC AND FIL TER CON TR OLS Filter Resonance contr ol Changes th e “Q” or sharpnes s of the VCF. Mild will give a smooth f ilter sound, Wild will make th e filter sound more pron ounced (sharper “Q”) Filter type select HPF - allows s ignals above th e cut-off freq uency to pass.
10 REAR P ANEL CONNECTIONS Phono inputs For connection to tu rntables only; this inp ut has RIAA eq ualization for moving magnet cartridges . Note: An internal mo dification can convert these t o Line (see page 14) Effects SND output Connect this output to the input of an ex- ternal effects unit.
11 FIL TER 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 pr oduces a much wider operating range and more control over the filter response to create unlimited combinations of tonal effect.
12 It is most important that the system lev el 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.
13 The connection to earth (ground) in an audio system i s important for two reasons: SAFETY - To protect the operator from high voltag e ele ctric 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.
