Take Control of Phase with the Radial Phazer!

The Radial Phazer works with any instrument, letting you easily put two sound sources into phase alignment for even fatter, richer tones. There's a single dial on the Phazer so you can quickly find the sweet spot between zero and 180 degrees, and a polarity reverse switch that gives you access to the 181-360 degree range for some seriously unique tonal textures. Plus, a variable lowpass filter lets you focus the effect in the lower frequency spectrum where phasing is most audible. Improve your sound today with the easy-to-use, ruggedly built Radial Phazer.

Radial Phazer at a Glance:
  • Easily time align two signals for fat, rich tones
  • Single dial control gets you there fast
  • lowpass filter lets you focus the effect
  • Built tough for the road
Easily time align two signals for fat, rich tones

With the Radial Phazer, you can bring two line level signals into phase for impressive results. Combine the direct feed of an electric amp with a room mic to create fat, rich tones. Or, on a kick drum, combine the "attack" sound from a batter head mic with the "boom" captured by a resonant head mic. Likewise, combine the top and bottom mics on a snare, or add texture to your acoustic instruments by combining a close "spot" mic with a room mic - however you use the Radial Phazer, you'll enjoy singing, synced-up tones you never thought possible.

Single dial control gets you there fast

The Radial Phazer has a single knob that makes it easy to zone in on the sweet spot between zero and 180 degrees. For the more adventurous, a 180 degree polarity reverse switch accesses the 181 to 360 degree range and lets you create weird to absurd "Phazed" tonal textures. The Phazer itself was designed from the ground up for optimum sound quality and boasts 100 percent discreet Class A circuitry for the ultimate in smooth and natural sounding phase curves.

Lowpass filter lets you focus the effect

Phase changes in upper frequencies are often inaudible - because of this, Radial gave the Phazer a high-cut filter (lowpass) to eliminate some of the phase anomalies and better focus the phase effect where it matters most - in the bass. A filter on/off switch allows you to compare the filter effect with the original tone. A cutoff range has been provided that lets you select between 38kHz down to 3kHz range or from the 3.8kHz down to 300Hz range. A smooth 6dB per octave filter is applied which is then controlled via the cut-off knob.

Built tough for the road

The Phazer is equipped with an innovative book-end design that creates a protective zone around the knobs and switches. Construction is 14-gauge steel with welded internal I-Beam frame that protects the sensitive electronics in even the harshest touring environments.
