Creating a very high fidelity, phase shifted version of the input, RSPhaseShifter provides a fast, convenient and musical means of aligning individual mix elements for best subjective result. RSPhaseShifter is great for any situation where you need to creatively control tonality, power spectrum and harmonic content through phase manipulation. Post–production, stem mastering, outboard gear compensation, film re–recording, “live” production, sound reinforcement, along with content creation for gaming and VR all benefit from having RSPhaseShifter on hand.
RSPhaseShifter was created in conjunction with Roger Schult/German Audio Lab, and is a painstaking, 64 bit digital realization of Schult’s trusted Phase Shifter W2324 analog phase rotator hardware. When multiple sources compete rather than complement, RSPhaseShifter should be your choice for a fast, intuitive, easy to use and effective remedy.
RSPhaseShifter: a mixer’s secret weapon, both live and in the studio…Whether it’s mix sessions with multiple tracks of one instrument, or alignment of spots and overheads, RSPhaseShifter makes quick work of cancellation issues, bringing back the richness and impact you cannot get from basic delay compensation. Match and optimize the time delay or phase response of a subwoofer in a surround monitoring environment, address fold–down issues or create thick, ultra–wide sounds and phase sweeps by deliberately manipulating phase of one side of a stereo track.
RSPhaseShifter’s analog–style controls are no accident. They’re the same controls found on the tried and true Phase Shifter W2324 hardware, only better. With no added noise, double precision internal processing plus support for AAX and 8x sample rates, RSPhaseShifter is a cost effective addition to any engineer’s toolkit.
As with all Roger Schult by MAAT products, the RSPhaseShifter is hand crafted and precision engineered in California by way of Germany. This is an explicit digital recreation of the analog W2324 topology, not a modeling or simulation algorithm. We copied the functionality of the original hardware without analog’s shortcomings. This tool´s value is more about what it does technically, so we left out stuff like fake transformer color, hum or Johnson Noise. There are lots of colorful plug–ins, we simply provide convenient access to the useful functionality along with a classic API Lunchbox look.
The original W2324 analog degree scale is highly non–linear, due to issues with analog circuitry. The original also has ten tick marks, from 10 to 125°. Freed from the limitations of an analog implementation, we have moved to a true, linear scale and extended the range slightly, something only possible in the digital domain. RSPhaseShifter’s eleven tick marks, in 15° steps, start at 15 and go to 180°; 15; 30; 45; 60; 75; 90; 105; 120; 135; 150; 180°
This three position switch is used to select the range of the phase shifter.
| Top position: | +180° (180 - 360°) |
| Center position: | Bypass |
| Bottom position: | 0 - 180° |
The center Phase position, the “0” setting or Bypass mode, provides a means to compare the effect of the selected phase shift with the unprocessed, original phase of the source material.
The phase shift is dependent on the selected frequency setting. The Frequency control is either stepped for repeatability or continuous; your choice. Resonant frequency selection is managed by an 13 step ELMA–style control with the following frequencies:
| 16 Hz | 400 Hz |
| 25 Hz | 630 Hz |
| 40 Hz | 1000 Hz |
| 63 Hz | 1600 Hz |
| 100 Hz | 2500 Hz |
| 160 Hz | 4 kHz |
| 250 Hz |
Additional controls include a ±5 dB of gain refinement plus MIRROR, FLIP and δ (DELTA) modes for use during stereo operation.
For most applications, it makes sense to use RSPhaseShifter on just one channel, rather than on both stereo channels. A common example would be when a stereo pair of ambiance mics suffer from slightly different distances to a localized source. Additional uses include:
