Heil Sound PR 77 Overview

The black body Heil Sound PR 77D is a large-diaphragm dynamic microphone designed to provide focused directionality, full-range frequency response, and a vintage appearance for use on vocals and instruments in podcasting, radio, 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.

With a high maximum SPL of 146 dB, it can handle a range of sources from vocals and horns to close-miked drums and guitar cabinets. It offers a 40 Hz to 18 kHz frequency response with a selectable high-pass filter at 80 Hz. The integrated microphone mount allows you to attach it directly to a mic stand without the use of an additional clip or shockmount. The PR 77's standard XLR 3-pin output ensures compatibility with most microphone preamps.

    For soft, sensually awesome sheets- LOOK no more!
    Color: 15 - Sage Green, Size: Full
    Would give 10 stars if possible! (And this is a nonpaid for review!) When I received the sheets, instantly I knew that I had the right ones, had bought a down comforter close in color as well.. these sheets? The material is strong yet, soft and warm. So so especially soft, and when I make up the bed, ahhh! plus the corners on the fitted, such a cinch to pull over the mattress, even with a topper on the bed! Feels almost spa-like <3 Very comfy, so far in the winter and in 85 degree heat! Soft and easy peasy to care for, too. Washing is a breeze, dry and fold. So far the only thing I can smell on these sheets is my wonderful detergent! Will purchase again. And possibly, again! Thank you!!

    Color is exactly as advertised. Feels very soft, fits perfectly. No weird odor and not too warm 🥵. Only downfall I can tell is it seems a bit thin.

    Very thin. You get what you pay for.
    Color: 01 - White, Size: Queen
    You get what you pay for. I first noticed the softness which was great. The quality is very thin. They are cool which is great. I have not washed them yet. I would suggest washing them on cool and gentle by themselves. And because they are so thin I would fluff dry for an hour if you have that setting. The two things that damages clothes and sheets, etc. are if you have an agitator in your washer, those ruin clothes and the heat you choose for the fabric you’re drying I always wash my clothes on cold. I do not have an agitator anymore and on delicate and thin fabrics, I use fluff dry. It is cool, but it will dry, especially if it is thin and I’ve had to dry my fine delicates a little bit longer on fluff that way they don’t shrink because the shrinking comes in from the heat from the dryer so keep that in mind another good thing to remember if you got white sheets like I did is that when you use your detergent add a little bit of borax or laundry booster and they will help get them clean and sparkly white. I am on the fence about whether I would recommend this or not if you’re tight on money and you take good care of them I would recommend that you get them. I’m a linen freak and I buy mostly expensive sheets and I thought I would try this out so that’s where I’m at.

    Love it
    Size: King (106"x96"), Color: Coin Pattern Black, Size: King (106"x96"), Color: Coin Pattern Black
    Love this set. It's stitched together so nicely and it's so freaking cute. It's lightweight, but doesn't feel cheap. Might have to get every color. True to size, fits great. It's soft and comfortable.
