Description

The Radial Phazer Class-A Phase Adjuster is your secret weapon for unlocking phase-coherent, multi-mic recordings that sing with rich, full-bodied tones. Whether you're recording electric guitars, kick drums, or acoustic instruments, the Phazer ensures that your sound sources are perfectly aligned, delivering a pristine, phase-accurate mix. With its intuitive single dial, you can effortlessly adjust the phase from 0 to 180 degrees, or push the boundaries by engaging the polarity reverse switch for a 181 to 360-degree range, opening up a world of creative tonal possibilities.

This Class-A phase alignment tool is engineered with 100% discreet components, providing seamless and natural phase curves, especially crucial in the lower frequencies where phasing is most noticeable. A variable lowpass filter allows you to hone in on these lower frequencies, reducing phase anomalies and ensuring your bass tones remain tight and impactful. Built with durability in mind, the Phazer's rugged 14-gauge steel chassis means it's ready for the rigors of both studio and road use.

  • Class-A circuitry with 100% discrete components for optimal sound quality
  • Single knob phase adjustment from 0 to 180 degrees, with polarity reverse switch for 181 to 360 degrees
