This has several uses. Of course, meetings and conferences are on its list of usage options, but it extends much further than that. This is a mic that can capture individual instruments and even full orchestras. And it would be able to handle full stage productions in theatres.

Why is it so special?

It has two frequency responses, flat or rising. Either of these may be selected to suit the application that is being mic’d. This gives more flexibility in where you can place the mic.

The frequency response is 20Hz to 20kHz, and it has a maximum SPL of 150dB. This means it can handle anything you decide to throw at it. The capsule mounts into what is referred to as the pressure zone. This is a space where the reflected sound and the actual direct sound are in phase. This makes it more sensitive, in fact, up to 6dB more sensitive.

The Build…

It has a very storing metal housing that will be able to withstand plenty of use and accidental knocks. There is a detachable cable. It measures 9.30 by 7.30 by 2.80 inches and weighs under one pound. It is fitted on a plate for securing its position.

Best Boundary Microphones Buying Guide

Best Boundary Microphones Review

All microphones perform better at certain things. But with Boundary mics, that is even more applicable.

What is it for?

Some will excel at the business meeting/conference aspect. They will have a wide field of sound collection, and the frequency ranges are perfect for voice. But those mics may not be suitable if you are thinking about instruments. Either in a group or solo.

The recording of musical sounds takes on a different requirement. Especially if it is an instrument with varying levels of volume. The obvious is drums, but a piano can also have a wide spectrum of sound. You will need a higher SPL from your choice if that is how you plan to use it.

Build Quality…

This is an issue for every mic, but with a boundary mic, it is important. Most can easily sit on flat surfaces, tables, or even the floor. The latter in the case of theater productions or even orchestras.

In which case, they need to be able to withstand accidents and take a few knocks. Possibly even trodden on. The quality and strength of the build are important.

The Budget…

This is an area that is also wide-ranging. Some boundary microphones are very expensive. But they may be designed for applications you don’t need. Choose your mic based on the priorities you have for its use.
