MU-FX MU-FX PHASOR 2X Manuals

1 MU-FX PHASOR 2X SPECIFICATIONS AND OPERATION MUSICIAN’S MANUAL 2 The Mu-FX PHASOR 2X is the enhanced reissue of the vintage classic Musitronics Mu-Tron® Phasor II The PHASOR 2X is a multi-mode phase shifter with enhanced audio and control features which provide simple, intuitive and performance-oriented control versatility. The PHASOR 2X retains the vintage classic sound of the Phasor II, which offered distortion- free audio processing and feedback-controlled effect emphasis for the cleanest possible sound. The Mu-FX Phasor 2X provides 4 and 6 stage OPTICAL phasing – for the best possible dynamic range and signal-to-noise ratio - without the distortion inherent in FET and transconductance-amp phasors. The EMPHASIS of the phasing effect is produced with FEEDBACK around the electro-optical resistive phase circuitry without creating distortion of the signal. To preserve the best possible dynamic range and signal-to-noise ratio, the Phasor 2X is powered from external 12Volt AC power and internal LINEAR voltage regulators. This eliminates the signal noise, distortion and radio frequency interference caused by “switching regulator” power supplies. The Phasor 2X also uses TRUE-GROUND dual power supply rails and other specialized components to further minimize distortion and sensitivity to external RF interference. The phase sweep is optimized for each unit to give the smoothest sounding sweep. The 4 and 6 stage phasing, controlled by a foot switch, is also optimized for best sweep range and characteristic for each type of phasing. Simple, intuitive, and performance oriented! The controls are very simple: RATE, DEPTH and FEEDBACK for each of the 4 and 6 stage modes. This allows easy and independent adjustment without having to compensate for the different characteristics of 4 and 6 stage phasing modes. The 4 and 6 modes are instantly accessible with the PHASE MODE foot switch. Pedal control switches for each (4 and 6) mode allow you to set dramatically different kinds of expression pedal (or external CV) effects. 3 FEATURES AND SPECIFICATIONS • 4 and 6-stage phasing modes (foot-switch selectable to main output) • Smooth and consistent phase sweep by LFO, expression pedal or control voltage • Stereo output for 4 and 6 stage modes (“secret sauce” phasing to second (or stereo) output) • Electro-optical phasing with superior dynamic range, no distortion and low noise level • Retro “Mini-MU” housing with original “Mu-Tron®” Phasor II color scheme • Powered by 12V AC for optimal dynamic range and signal-to-noise ratio LFO starts precisely from the LOW END OF SWEEP when effect is engaged. So, you can count on a consistent, predictable LFO sweep, especially good for slow sweep rates! Footswitch control and dual-color LED indicator for 4 or 6-stage phasing and control set BLUE is for 6-Stage Phase (and top BLUE knob pointers) GREEN is for 4-Stage Phase (and top GREEN knob pointers) EFFECT/BYPASS Footswitch and 3-color LED indicator RED for BYPASS BLUE-to-GREEN for PHASE RATE or SWEEP RED/BLUE or RED/GREEN for pedal control indicator Expression Pedal or CV control of RATE or SWEEP for both 4 and 6-stage phaser banks All audio switching by “silent” footswitches and electromechanical relays Internal Switch setting for TRUE or ACTIVE bypass: (MAIN and STEREO outputs)
