The short answer: Setting up the Heil Sound PL-2T shock mount is straightforward once you understand its unique tension-adjustment system. You’ll need to match the mic diameter, adjust the tension knobs, and secure the mic. For most popular mics (like the Shure SM7B, Electro-Voice RE20, or Heil PR40), it’s a simple twist-and-tighten process. This guide walks you through every step, including compatibility notes and pro tips.

The Heil Sound PL-2T is a dual-tension shock mount designed to hold large-diaphragm dynamic microphones securely. Unlike traditional spider mounts, it uses two adjustable arms with rubber bands and a central yoke. The key is the tension system: two knobs on each side control the tightness of the rubber bands, allowing you to fine-tune the grip based on your mic’s weight and diameter.
Before you start, ensure your microphone falls within the PL-2T’s range: it fits mics from about 1.5 to 2.2 inches in diameter (roughly 38-56 mm). Most broadcast and podcasting mics like the Shure SM7B, Electro-Voice RE20, and Heil PR40 are in this range. If your mic is smaller or larger, you might need additional adapters or a different mount.
Step 1: Attach the Mount to a Stand
First, screw the PL-2T onto your microphone stand using the standard 5/8-inch thread. If you have a European stand with a 3/8-inch thread, use the included adapter. Tighten securely.
Step 2: Open the Yoke
Loosen the two tension knobs on the sides of the yoke. This will allow the arms to swing open. Pull the arms outward to create enough space to insert your microphone.
Step 3: Position the Microphone
Place the microphone body between the two rubber-lined arms. The arms should cradle the mic at its center of gravity, usually around the middle of the body or slightly above the XLR connector. For mics like the SM7B, you may need to adjust the vertical position so it balances well.
Step 4: Tighten the Tension Knobs
Bring the arms together around the mic. Turn the tension knobs clockwise to tighten. Start with equal tension on both sides. You want the mic to be held firmly but not so tight that it compresses the mic body. A good test: gently wiggle the mic; it shouldn’t move on its own, but you should be able to adjust its angle with a little force.
Step 5: Fine-Tune the Angle
Once secure, you can tilt the mic by loosening the wing nut on the side of the yoke. Set the desired angle and re-tighten. The PL-2T allows smooth rotation for optimal positioning.
Shure SM7B: The SM7B is a classic match. Because it’s a bit heavy (about 1.7 lbs), you’ll need to maximize tension. Tighten the knobs firmly. Many users find the PL-2T works perfectly, but be aware that the SM7B’s weight may cause slight sagging over time. Check the rubber bands periodically for wear.
Electro-Voice RE20: Similar to the SM7B, the RE20 is heavy (1.4 lbs) and wide. The PL-2T fits it well, but ensure the arms are fully open to accommodate the 2-inch diameter. You might need to adjust the yoke position to balance the mic correctly.
Heil PR40: This is a natural match since both are from Heil. The PR40 is lighter (1.1 lbs), so less tension is needed. The PL-2T holds it securely, and the integrated pop filter on the PR40 doesn’t interfere.
For smaller mics like the Shure SM58 or Beta 58A (1.5 inches), the PL-2T might be too large. However, you can use foam padding or rubber bands to adapt, but a dedicated universal shock mount might be better. For a comprehensive comparison of shock mounts, check out this best shock mount guide.
Mic Slipping: If the mic slips, increase tension on both sides. If it still slips, the rubber bands may be worn. You can purchase replacement bands from Heil or use a thin rubber sheet for extra grip.
Mic Too Big: If the mic doesn’t fit between the arms, you might have a large-diaphragm condenser like an AKG C414 (2.1 inches). The PL-2T can stretch to hold it, but it may be a tight fit. Loosen the knobs fully and gently push the arms apart. If it feels too tight, consider a larger mount.
Resonance or Vibration: The PL-2T is designed to isolate vibrations, but if you’re still getting rumble, ensure the stand is stable and not touching any surfaces. Also, check that the rubber bands are intact.
1. Balance is key: Adjust the position of the mic in the yoke so that it feels balanced. This reduces strain on the rubber bands and ensures stable placement.
2. Use a pop filter: While the shock mount reduces mechanical noise, it doesn’t control plosives. Combine with a pop filter for clean vocals.
3. Regular maintenance: Inspect the rubber bands every few months. They can stretch or crack over time. Replacements are inexpensive and easy to install.
4. Angle adjustments: Loosen the wing nut slightly to adjust the mic angle. Tighten securely once set.
One of the most common questions about the PL-2T is whether it will fit a specific microphone. The mount is designed for large-diaphragm dynamic mics, and its adjustable arms accommodate a range of diameters. The official specification states it fits mics from 1.5 to 2.2 inches (38 to 56 mm) in diameter. However, real-world fit depends on both diameter and weight.
If your mic is on the smaller end of the range, such as a Shure SM58 (about 1.5 inches), the arms may not grip securely without extra padding. Some users wrap a thin layer of foam or rubber around the mic body to increase friction. But keep in mind that adding padding can affect the mount’s ability to isolate vibrations. For mics significantly smaller than 1.5 inches, the PL-2T is not the right choice; a universal shock mount with a basket design may be more suitable.
On the larger end, mics like the Electro-Voice RE20 (about 2 inches) and the Heil PR40 (about 1.9 inches) fit well. The arms can be spread wide enough to cradle these mics, and the tension knobs provide enough force to hold them. However, if your mic exceeds 2.2 inches, such as some large-diaphragm condensers, the PL-2T may be too small. Forcing the arms apart can stress the rubber bands and reduce the mount’s effectiveness.
Weight is another critical factor. The PL-2T is rated to hold mics up to a certain weight, though Heil does not publish a specific limit. Based on owner feedback, it handles the Shure SM7B (1.7 lbs) and RE20 (1.4 lbs) without issue, provided the tension is adjusted correctly. Heavier mics, like some vintage dynamics, may cause sagging over time. If your mic weighs more than 2 lbs, consider a heavier-duty mount.
To check fit before buying, measure your mic’s diameter at its widest point (usually the body, not the grille). Also, note the weight. If your mic falls within the diameter range and weighs under 2 lbs, the PL-2T is likely a good match. If not, explore alternatives.
The PL-2T is a durable piece of gear, but like any mechanical device, it benefits from regular maintenance. The rubber bands are the most wear-prone component. Over time, they can stretch, lose elasticity, or even crack, especially if exposed to sunlight or extreme temperatures. Inspect them every few months. If you notice the mic sagging or slipping, the bands may need replacement.
Heil sells replacement rubber bands specifically for the PL-2T. The replacement process is simple: remove the old bands by sliding them off the metal posts, then stretch the new ones over the same path. It takes about five minutes. Avoid using generic rubber bands, as they may not have the same elasticity or durability.
Clean the mount periodically with a dry or slightly damp cloth. Avoid solvents or harsh chemicals, which can degrade the rubber and plastic components. If you use the mount in a dusty environment, such as a workshop or live venue, consider covering it when not in use to prevent dust buildup in the tension knobs.
The tension knobs themselves can loosen over time. If they no longer hold tension, check for stripped threads or debris. A small amount of silicone lubricant on the threads can help, but use it sparingly to avoid attracting dust. If the knobs are damaged, contact Heil for replacement parts.
Store the mount in a dry place. If you transport it frequently, consider a padded case to protect the arms and bands from bending or snagging. With proper care, the PL-2T can last for many years.
Even with a straightforward design, users sometimes make mistakes that compromise performance. Here are the most common pitfalls and how to avoid them.
Over-tightening the tension knobs: It’s tempting to crank the knobs as tight as possible, but this can compress the microphone body and potentially damage the mic or the mount. Tighten just enough to hold the mic securely. You should be able to adjust the mic’s angle with moderate force, but it shouldn’t move on its own.
Positioning the mic off-center: Placing the mic too high or too low in the yoke can cause imbalance. The arms should cradle the mic at its center of gravity. For most mics, this is near the middle of the body. If the mic feels top-heavy, adjust its position until it balances.
Ignoring the stand: The PL-2T isolates the mic from vibrations, but if your stand is flimsy or on an unstable surface, you’ll still get rumble. Use a sturdy stand and ensure it’s not touching walls or desks. A boom arm with a counterweight can help.
Using the wrong thread adapter: The PL-2T has a 5/8-inch thread, common in the US. If your stand has a 3/8-inch thread (common in Europe), use the included adapter. Forcing the mount onto the wrong thread can strip the threads.
Neglecting rubber band wear: Worn bands are the leading cause of mic slippage. Replace them as soon as you notice reduced elasticity. Keeping a spare set on hand is a good idea.
Assuming it fits all mics: As covered in the fit section, the PL-2T has size and weight limits. Don’t try to force a mic that’s too large or too heavy. It won’t perform well and may damage the mount.
Yes, the SM7B fits directly. You just need to tighten the tension knobs firmly to hold its weight. Many users report it works perfectly.
Generally, yes, if the condenser has a diameter within the range. However, some large-diaphragm condensers are wider. If it fits, the shock mount will work, but be cautious with heavier condensers that might exceed the tension capacity.
Heil sells replacement bands. Remove the old bands by sliding them off the posts, then stretch new ones over. Follow the original path. It’s a 5-minute job.
