Heil Sound is pleased to introduce the PR 77D, a large-diaphragm microphone designed to provide focused directionality, full-range response, and a vintage appearance for use in podcast, broadcast, recording, and live stage applications. It features a classic side-address design based upon popular RCA microphones from the ‘50s and ‘60s. Its cardioid polar pattern delivers 40 dB of attenuation 180° off-axis, resulting in a tight pickup area and minimized bleed. The PR 77D is an updated version of the PR 77 from Heil Sound.
The Heil PR 77D features a two-position switch allowing the selection of the best characteristics of voice or music. The voice position rolls the audio off at 120 Hz at -6 dB per octave while the music selection removes the filter and the entire audio spectrum of 60 Hz to 16 kHz is present.
Standard 5/8” – 27 microphone stand threads allow The PR 77D to be mounted directly to booms or bases. The PR 77D retails for $249.00 USD and is available from authorized Heil Sound dealers.

I can’t seem to find any information about the type of cable/connector this mic uses. USB, XLR, etc. Also…in case my email didn’t go through…your email announcement for this mic has a broken link to the product page.
Hi Steve! The microphone has an XLR connection. You can check the specs section on each product page for information on connection type. All our Pro audio microphones are 3-pin XLR. Thanks for the heads-up on the link.
This is an outstanding microphone we have four of them in use in our broadcast facility we find them to be excellent sound quality and very versatile.
What’s the difference between the PR77D and the original PR77? I purchased a PR77 from you, shortly after it became available, after improvements to it were made. I was wondering if I would also like to try a PR77D, as well. I’ve tried using the PR77 outside. on a mic stand, as a vocal mic, but it seems to be much more sensitive to feedback than a PR35, even though, I thought that they share the same element. What element does the PR77D use, or what mic does it share a common element with? The Fin seems to be easier to EQ outside than the PR77. I commonly use it with two Bose L1 Model II system which are set in the rear, so floor monitors are not needed. They may need to be set to the front and used with floor monitors, to eliminate the feedback with the PR77. I put a black ankle sock over it as a wind screen. It works very well.
Love the ankle sock as a windscreen!
The PR 77D features the PR 40 element. The PR 77 and the PR 77D are really intended to be used on a boom arm and are better suited for broadcast, podcast, or streaming. The Fin was designed more to be a live mic.
Quick question:
I have the PR 77D and I was wondering what the two modes (Voice and Music) were really for. I hear the Voice mode very different in the lower frequency’s. There seems to have little to no lower frequency’s. Is there a precise use for this mode?
Yes, the PR 77D’s voice mode has a low pass filter on it. It is best suited for tailoring a response to the spoken word. If you have a deeper voice it is actually better to use the full range of the element in the music mode. Thanks for the question!
Thanks for finally writing about >Introducing
the PR 77D – – Heil Sound <Loved it!
This mic has a pretty harsh upper mid range. Requires a lot of EQ to sit right. It’s really unuseable without lots of EQ adjustment. Is that normal, or do I have a defective one?
The “voice” roll-off position on this mic can hit certain male voices in a harsh way. We recommend leaving it in the “Music” position.
I agree, make sure you use the Music mode. Voice mode seems to be tailored to Ham Radio use as rolls off everything below 220Hz . It is a bit confusing due to the fact that many other mics that have bass roll off switches use a roll off around 80-100Hz. I think it should be labeled as the Ham switch on this mic. 🙂
I’m trying to decide between the original PR77 (which are still available from some outlets) and the 77D. What exactly are the differences between the two besides the slightly different visuals?
The PR77 has a PR 20 element in it. The PR 77D has a PR 40 element in it.
