Presented in a sturdy low-profile metal housing, the Senal MXBM-621/C is a MX Series condenser boundary microphone offering enhanced speech intelligibility with low noise for conferences, meetings, training sessions, and more. Its cardioid polar pattern reduces pickup of off-axis ambient noise and reverb to deliver a more focused, direct sound ideal for untreated rooms. The 30 Hz to 20 kHz frequency response yields reliable clarity, and can be tailored to attenuate additional low frequencies via the selectable high-pass filter. Non-skid rubber padding on the bottom of the MXBM-621/C decouples it from surface-born vibrations, and keeps it in position even on slick tabletops.

A silent CapSense touch-to-mute switch allows convenient manual control of signal activity, while mute on/off status is indicated by a dedicated LED. Connect the balanced low-impedance TA3M output to your mixer with the supplied 25' TA3F to XLR 3-pin cable. Both the cable and microphone are shielded to negate noise from RF and EM interference. The MXBM-621/C is operated via 9 to 52 VDC phantom power, no need to replace or recharge batteries.

Condenser Capsule

Powered via 9 to 52 VDC phantom power from a mixer or microphone preamplifier, the MXBM-621/C's condenser capsule delivers full-range frequency reproduction with high sensitivity, making it compliant with a variety of mic preamps.

Cardioid Polar Pattern

The cardioid polar pattern of the MXBM-621/C rejects off-axis sound from the rear of the mic while providing directional pickup from the front, allowing it to capture the intended source with attenuated room ambience. The cardioid polar pattern is well suited for use in rooms without acoustic treatment.

Intelligibility Optimized for Voice

The MXBM-621/C's 30 Hz to 20 kHz frequency response enhances speech intelligibility without sacrificing low or high end.

Selectable High-Pass Filter

A selectable high-pass filter applies 10 dB (± 2 dB) of attenuation from 60 to 200 Hz, effectively minimizing problematic low-frequency content from errant vibrations and rumble from HVAC systems.

Balanced Low-Impedance Output

The TA3 output connector contributes to the microphone's low profile, and allows quick hookup of the supplied 25' TA3F to XLR 3-pin cable for proper interfacing with most mixing consoles, PA systems, and mic preamps. The MXBM-621/C's balanced low-impedance output inhibits common sources of interference such as RF and EM while being compliant with extended cable runs.

Protective Shielding

Both the microphone and included cable are shielded to impede noise caused by electrical interference from mobile devices and light sources.

Convenient Touch-to-Mute Switch

Silent and convenient, the CapSense switch grants simple touch-to-mute functionality to avoid unnecessarily passing signal. A dedicated LED clearly indicates the MXBM-621/C's mute status.

Non-Skid Rubber Padding

To prevent the transfer of floor- or table-born vibrations to the microphone, the MXBM-621/C features non-skid rubber pads on its bottom surface. In addition to decoupling the microphone from your desk or tabletop, they keep it firmly stationed devoid of accidental slippage.

Senal MXBM-621 Reviews

Great for conferences AND vids

By Jeremy
Rated 5 out of 5
Date: 2021-11-04

If you want better audio quality without having a microphone in your camera shot....this is a very good choice. Specifically...the omnidirectional for acoustically treated spaces, and the cardioid for more typical home rooms. Great build quality and size...and most importantly...very good sound quality for it's price. [I have received this product in exchange for my honest review]

Great for recording audience on live events

By Art Video
Rated 5 out of 5

I would guess, most people will use this mic (for being omnidirectional) to capture audio from conference meetings and similar situations, since it will capture sound from all directions. This mic will also be very useful to set it up at a podium to capture audio from speeches at a seminar, church, (as close as possible to the source for best results with this mic or any mic) or during a wedding ceremony. But I'll be using this mic for production with a dedicated separate recorder specifically to capture audience from live events to add it separately into my final product mix (audio for video) which I can control how much of the audience audio I want to add. This mic, for being a Condenser mic, it is sensitive and also has sensitivity to bumps and vibrations like a condenser should, but, testing this mic, walking on a wood floor, it held vibrations well, similar to a dynamic mic, which gives me the idea to want to test this mic, centered at the very edge at the of a high school Stage (dance recitals, foot tapping etc), with the same purpose, adding that extra and separate sound to my mix. Maybe placing a foam underneath in this experiment would help minimize unwanted vibration or thumps. (I have NOT tested this yet but I would think it may work) Sound: The cable that comes included with this mic has a low handling conduction, which is good, because it helps prevent noise handling transmission, and since the cable will also be on the floor , eliminating noise transmission via the cable wire. This mic is the BRIGHTEST in highs I've ever heard on a mic before post. The highs are almost excessive when speaking at it, especially at close proximity, It's a little too essy for my taste (and I like highs though) but the S doesn't bleed. This mic has a frequency attenuator at the bottom plate. You'll need a little tool (not included) to set it, such as a mini flat head watch screwdriver sort of thing, or even a toothpick.... One interesting thing I find, was that the mic, even without the attenuation switch on, it doesn't capture unwanted bass in the voice, however, when I took it outside to record a test audio with nature sounds and ambience which also includes occasional vehicles, it recorded lots of low frequencies, which that extra bottom weight audio can be desired, especially for movie production. There was a Mustang and a truck that passed by, and the low frequency recorded from the vehicles was actually too much and too loud compared to all other frequencies. Additionally, the sound captured from the vehicles, this mic had a very annoying frequency around the 50-60 Hz, which you will need to treat it in post. I switched to the low cut filter to cut down the bass from the car / truck scene, recorded it again and it was perfect, STILL with a decent amount of low frequency reduced, but again, there was still the 50-60 Hz annoyance being too pronounced, even after the low cut attenuation, but less pronounced than with no low cut filter. Again, with recording VOICE ONLY, you can leave the switch set to normal (full range). It somehow doesn't add unwanted bass in the voice at all. For recording audiences and nature sounds, it would be cool if Senal made a Stereo version of these mics. Maybe they already have? This item does NOT come with a case, but if you want to protect you mic, here's a very affordable suggestion: Auray WMC-100 Wide Mouth Case, or, BH #AUWMC100 I received this product in exchange for my honest review]

Works great with Sony HXR-MC88 camcorder, no mixer.

By Shazad
Rated 4 out of 5
Date: 2021-03-30

Work for a university and with everything going virtual wanted to use a couple of these for events, classes where I can't use a wireless mic/ mixer setup. These are great, uses phantom power though. Luckily my Sony HXR-MC88s' have built-in XLR connectors and 48V phantom power. This worked great for an event where I needed to cover audio across a split room. I noticed that when you press the mute button and the LED light turns on (I assume is when the mics are muted) I get audio pickup. When the button is pressed a second time and the LED goes out, no pickup, the opposite of how I was expecting it to work. But overall, nice long XLR to mini XLR cable and nice rugged design and has a lo pass filter.

Would this mic work for people sitting 4 or 5 feet away? Any idea of the distance this could cover?
Asked by: Angel
Yes, the MXBM-621/O can capture audio from people speaking who are 4 to 5 feet apart. The distance for coverage will vary depending on the environment where the mic is being used. The omnidirectional pattern picks up sound from 360 degrees and works best in quiet environments. Mics of this nature are often used for conferences and meetings. The mic is placed in the center of a table and picks up the voices of participants seated around the table.
