Audio-Technica PRO 45 Review

When I look at the Audio-Technica PRO 45, I don’t see a casual plug-and-play computer mic. I see a compact black XLR microphone that only makes sense if the rest of the setup is ready for it. That distinction matters. If someone is shopping for a simple microphone to plug straight into a laptop, I’d steer them away. If they already have, or plan to buy, XLR-capable gear for a Personal Computer setup, the PRO45 becomes a more sensible candidate.

Why the small PRO45 body matters

The first spec that catches my attention is the size. At 2.25 x 0.5 x 0.5 inches and 5.6 ounces, this is a very compact microphone on paper. I’d consider that useful in any setup where the microphone should stay visually discreet rather than dominate the desk or recording area.

The Black finish supports that same low-profile idea. This is not a screen-heavy, control-covered device either; it has no color screen. Personally, I don’t see that as a problem for this type of mic, but it does mean buyers should not expect onboard visual menus or display-based controls.

The XLR connection is the real buying decision

The connector type is XLR, and that is the spec I’d focus on before anything else. XLR is useful in more traditional audio chains, but it is not the same as USB. For a Personal Computer setup, I’d plan on using suitable XLR-capable hardware between the microphone and the computer.

That also makes this less convenient for beginners who want the fewest possible parts. The PRO 45 is listed as Corded Electric with 240 Volts, so I would treat it as a wired microphone for a fixed setup, not a portable or wireless solution. If cable-free operation is the priority, this is not the direction I’d go.

What I would check before ordering

Before buying the Audio-Technica PRO 45, I’d confirm that the rest of the audio chain is already compatible with XLR. I’d also check whether the physical size fits the intended placement, because the compact body is one of the main reasons to consider it.

• I’d consider it for: a PC-based audio setup that already includes XLR-compatible equipment.
• I’d skip it for: direct USB use, wireless recording, or anyone wanting a built-in screen.
• Key limitation: the microphone depends heavily on the rest of the wired setup, so the connector choice matters as much as the mic itself.

The model number is PRO45, the country of origin is Japan, and it is not listed as discontinued by the manufacturer. It first became available on April 10, 2018.
