SE ELECTRONICS DM1 Dynamite Ultra-Slim Inline Microphone Preamp for Ribbon & Dynamic Microphones - Mic Preamp with +28dB Gain for Clean, Natural Sound - Ideal for Podcasting & Live Sound (Red)

Briefly, I became aware of “HEIL” a few years ago having bought two Heil’s Air Transformer studio quality loudspeakers, whose sound is unparalleled. Therefor, as HEIL has been producing legendary loud speakers, let see if HEIL could also develop the opposite end of the audio channel, the Microphone. As a Faculty member of a 30,000+ student, State of Florida University, FAU, I rarely have time to write product reviews. My exception is for true Excellence, the valedictorian of products. Today, I produce daily, morning HDTV 90 minute pod-casts on a variety of technology topics, occasionally drifting to “Current Events.” In sum, HEIL PR-40B Microphone, is truly one of the best Cardioid Microphones available. Frequency response is pure and clean, particularly at the low-end of the audio spectrum. If you are looking for truly Deep, Clear Voiced Podcasting, with superior rejection of side & rear distractions, this may be a choice to consider. I have tested and own the best from EV, SHURE to SENNHEISER, where would you believe, HEIL clearly out-performs them all. If you deserve the Heil-PR40B (XLR fitted) microphone, you may likely be attaching it to a RODE Podcaster Pro-II or RODE’s new Podcaster-DUO, a mobile audio production sound-board, both offering phantom 48v power, coupled to SE Electronics DM1 in line 28db amplification, the subject of this review. Accordingly, SE-Electronics delivers their “in-line” DYNAMITE DM1 Class-A amplifier, for Dynamic Microphone in-line pre-amplification; the DM1 delivers truly “Lossless, Flat” preamplification of the entire 10-100,000 Hz audio spectrum, virtually eliminating line losses. Quality Dynamic microphones generally need an in-line 28db boost in signal amplitude, utilizing true Class-A amplifier technologies, this in-line signal boost, avoids over-pushing the RODE sound-board, keeping its attenuation in the mid-range of its capability, with long or short cable runs. Microphone Developers like Bob Heil, have a priority of delivering excellent sound reproduction for the entire listening range of the human Ear. Accordingly, Dynamic Microphones need a little help with signal attenuation; This is where SE-Electronics delivers their “in-line” DYNAMITE DM1 Class-A amplifier, fitting into the Audio Chain. We own four of these inline amplifiers for each of our 4 sound sources. 2/25/25 JimW.

It wasn’t what I needed in the end, but it worked exactly as intended and I had zero issues with it.

I record meditation videos and talk softly. This condenser amplifies my volume significantly and has greatly improved the quality of my vocals. I’m able to turn the gain down to approximately 30% and has reduced the noise my mic was picking up. Best money ever spent. I’ve had this problem for two years, I just wish I would’ve researched a little further two years ago. I’ve only had it for a few weeks, so I’m hoping that it stands the test of time.

Sometimes you need a power boost on a professional microphone; this provides it. Excellent clear boost with no noise. I have two different brands, this now being one of them, and it works just as well as the other. Do your research, and find out what you need. It goes with you very easily, and plugs in line rather than a box that you have to find a place to sit down. Both work equally well, but this sleeker design, with a better power boost from what I read works great.

I use a RODE Podmic with a Scarlett Solo 3rd gen, mostly for use with discord. I was having issues with my mic making crackling/humming noises, so I bought this product. It totally fixed that issue and even made my mic sound better, since I no longer have to keep it at max gain. But, it does stick out quite a few inches behind my mic which is kind of annoying. If you're willing to spend a little more money to avoid this (about $50 at time of this review) you should get the Cloudlifter CL-1. But, then you have to buy an extra XLR cable as well, so it's a tradeoff regardless. Either way, pretty happy with this product and definitely recommend if you're having the same issues with a similar setup!

Ton of clean gain. Sounds great, very durable, works well, easy, little pricey

A Shure WH20 can work directly with a Pyle XLR to USB (PDUSBPP10) adapter with one caveat: the build-in mic monitor will not work. This is because the monitor taps the mic input before the digitally (software) controlled preamp, and the signal from the WH20 is not enough to be heard via the monitor feature of the Pyle XLR to USB adapter. Without the Dynamite, the Pyle adapter needs to maximize the mic gain (0db) to get a decent recording. With the Dynamite, the digitally controlled preamp only needs to be at -34db to get a very clear input from the WH20. The monitor feature of the Pyle adapter works great. I can put the mic/computer balance right in the middle, and turn the headphone dial at about 8:30 (very low setting) and get a good balance between my own voice via the WH20 and whatever is coming from the computer. The Dynamite itself has no detectable noise or distortion. I am not an audiophile, just a practical person using this set up for Zoom meetings, recorded demonstrations and music listening. I did watch many videos that test and evaluate the Dynamite, I suggest that you do the same before reaching your own conclusion.

I've tied the cloud lifter and this product now (3 months of use). I am using the SE1 with a Shure SM7B. The output is clean and noiseless from my use. My signal chain is SM7B > SE1 > Focusrite Clarett 8PRE > Logic Pro. There is no color added through this line preamp. As with anything, you will need to EQ whatever you are micing (in this case vocals). It adds the gain needed to keep the preamp noise low. Love it and it's worth the investment. Additional Pros: Much smaller than other options, sturdy build, portable and sounds great (or actually adds no sound at all :) )! Cons: Wish it came with a carrying case.

I’m using this with my RODE PodMic, and the difference was immediate. Before adding the SE Electronics DM1 Dynamite, I had to crank the gain way up on my audio interface (Focusrite Scarlett Solo), which introduced a lot of background noise. With the DM1 plugged in, I get clean, strong gain without having to push my interface too hard. This thing is tiny, super solid, and does exactly what it claims. It gives my dynamic mic the extra boost it needs without distorting the sound. Everything stays transparent and crisp, which is perfect for voice recording and podcasting. Also, it’s plug-and-play—just insert it between your mic and XLR cable, and you’re good to go. No knobs, no fuss. Just clean gain. If you’re using a mic like the PodMic, SM7B, or any other gain-hungry dynamic mic, this is a must-have tool in your setup. Highly recommend it.

Absoluter Must have wenn man ein SM7b hat klingt sehr sauber keine Störgeräusche oder ähnliches super Qualität

比較対象を持っていないので詳しくは無いのですが、しっかりと音量が上がりますし、音質やバランスが変わるといったクセもありません。ノイズが大きくなっているわけではないですが、押さえられているという事も無い気がします。出力が上がり、ノイズも大きくなっているわけではないので、ゲート等でのノイズコントロールはしやすくなったと思います。

Smb7 + GOXLR peoples said i was quite, not so quite now :D Jokes aside, this gave enough gaine to cheer people up in discord.

impressionante qualidade de som, gigantesca!
