Shure SM7B + Rode PSA1: for sure a great combo

Let’s start with the warning, because it nearly took my eye out.

The Rode PSA1 has a seriously strong spring, and it’s still under full tension after you’ve assembled the arm. I knew that. I was careful. And with no microphone attached to weigh it down, the moment I touched it the arm snapped upwards and missed my eye by half a centimetre. I got away with a minor cut — it could have been a genuinely nasty injury.

So before anything else: when you set one of these up, keep the arm strapped down — the sticker Rode includes works, cable ties work better — until the microphone is actually mounted. It’s the weight of the mic that keeps the spring in check. Be extra careful. Right, warning out of the way.

Why a boom arm at all

When you’ve spent SM7B money on a microphone, you want the sound it’s capable of — not hours of post-processing rescuing recordings. My problem wasn’t the mic. It was the desk. Every keyboard tap, every knock, every bit of fidgeting travelled up the £10 Samson desk stand and into the recording as low-level rumble.

To be fair to the Samson: for a tenner it’s a steal, and on a bigger desk — or with a shock mount, or a more forgiving setup — it might serve you fine. It just wasn’t right for how I record.

I’m not going to rehash the SM7B gain-versus-noise debate — there are a hundred videos on that already. Short version: this mic is gain-hungry, and the more gain you add at the preamp, the more of everything else you amplify too, desk rumble included. The popular fix is an inline booster like a CloudLifter, but adding another box in the chain felt like treating the symptom — and, as I understood it then, potentially trading away a little of the SM7B’s character. My plan was the opposite: kill the noise at its source first, and only then decide if I needed more hardware.

Moving the mic off the desk entirely was the cheapest honest experiment. And the SM7B has internal shock absorption built in, so my bet was that arm + internal isolation would mean no shock mount, no booster, no extra boxes.

Years on, I can tell you that while the arm has helped immensely, the preamp quality seems to do the heavy lifting. I am now using the Rodecaster Pro II with it, and whilst it doesn’t entirely reduce noise, I’ve learned that it’s a tiny bit of work in Audition to remove room noise — or, if I am already editing a video, to use the Voice Isolation toggle in Final Cut Pro. So it really came down to a combination of factors: removing noise at source, treating the room as much as possible, and using software to finely tune the noise removal.

Living with the combo

The PSA1 itself is sturdy, moves smoothly, and the black finish looks nice and discreet on camera. Sure, it’s probably surpassed now by sleeker competitor options, but it’s still doing the job I got it for. I originally planned to bolt it through the desk — it deserves that kind of permanence — but the desk clamp holds so well that drilling never happened. In my case it was actually clamped to the window ledge rather than the desk, for many years, before I moved to a studio — which tells you how flexible the mounting is. No drilling also means you can rearrange your studio on a whim, which I have, several times. Now I am in a studio space — I will write more about that in another article — but the PSA1 remains with me.

Two practical notes if you’re buying:

• If you want to swing the SM7B around freely, you’ll need Shure’s extra fitting for full 360-degree rotation without unplugging the XLR every time. Budget for it.
• Measure your desk. The PSA1 has a proper reach, and on a small or shallow desk it can dominate the space.

My chain at the time was the SM7B into a Focusrite Scarlett 4i4. The Scarlett is still in the studio, but now supporting my gaming speakers and the baby brother Shure MV7 — but that’s another story. The Rodecaster Pro II is powering the SM7B these days but honestly, the Focusrite alone was doing a great job for the money.

The verdict, years later

The scores tell the story. Ease of use is a 10 because once it’s up, this combo simply works — position the arm, talk, done. Build and value sit high because both pieces are built to outlast the fads. Sound quality at 7.5 isn’t a knock on the SM7B’s character — it’s an honest reflection that out of the box, at this gain appetite, you’re working harder than you should for broadcast sound. And versatility at 7.5 is the SM7B being brilliant at voice and indifferent to much else.

Would I buy both again? 100%! Just watch that darn spring if you get the same arm!
