4 automatic audio mixers ≤US$1000 cure bleed/spill/crosstalk

Whether you call it bleed, spill or “crosstalk”, these special automatic mixers can reduce or eliminate it.

Have you been disappointed when your audio quality drops exponentially as you add more microphones with a talk show, interview or reality, due to a phenomenon called spill, bleed or “crosstalk”? You can’t afford the time to mulitrack and fix it in post? You’ll be happy to know that there are hardware devices to solve it in real time, either truly live or live-to-drive (previously known as “live on tape”) . In BeyondPodcasting episode 10, Curtis Judd and I discuss four models from ≈US$250 to ≈US$1000.

Solutions discussed in this episode:

  • Zoom F8n (≈US$999 AmazonB&H) +75dB maximum gain, noticeable delay/latency in monitoring headphones when using automix, as discovered by Curtis Judd of Learn, Light and Sound.
  • Audio-Technica ATDM-0604 (≈US$899 AmazonB&H), +60dB maximum gain, gate or automix modes, no built-in headphone output, review pending.
  • Audio Technica AT-MX351a (US$829 AmazonB&H, +73dB maximum gain, which I reviewed in 2014, and fortunately had no perceptible delay when monitoring via its headphone output. The AT-MX351a contains no digital output. Nowadays, I would use it with the iRig Pre HD to convert the analog signal bidirectionally from and to digital for Android, Chromebook, Mac or Windows, rather than the older model used back in 2014 and mentioned in the AT-MX351a review.)
  • Behringer X AIR XR12 (≈US$250 AmazonB&H), +60dB maximum gain, US$250, which I covered in several articles)
  • Multitrack crossgating from Auphonic (in post-production, not live, see My multitrack crossgating audio workflow to eliminate crosstalk)

Also, listen to Chris Curran’s interview with Dan Dugan on Podcast Engineering School. Dan Dugan was the original inventor of automix, although his patent has since expired.
