SE ELECTRONICS - Dynamite Active in-Line Preamp

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.

Using this with the Shure SM7B and even though I have an interface with enough of a preamp to handle that mic, this adds that extra gain so your interface doesn't need to push hard at all. It's clean gain too which I'm really happy about. It's been great for voice and vocals.Love it's ease of use too: turn on phantom power and plug it inline and you're done.Well done. Very well done.

This is absolutely awesome! Gave me so much more volume than my cloud lifter which is what it was replacing. Maybe I always had it effective cloud lifter and just didn't know it. But this one gave me the volume I was looking for. In fact too much volume really. Use it with my focusrite and my shure sm7b. My favorite ever!

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 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!

Boosts my mic!

The only negative to the D1 isn't really a negative as much as it's an observation. The D1 is long. The fact that you can put it anywhere in the line mitigates that factor though. As to performance, I'm running an ElectroVoice RE20 with it. In a word, perfect. There is no hum, nothing but pure sound from the mic. I also tried it with my Shure SM 7B. Same results, perfect.The D1 does require phantom power so be sure you understand that before buying. Any decent mixer will have phantom power though so it's not a big issue. I have a Behringer Xenyx 1204 USB. It's old, but it still works good for my podcast.I liked the D1 so much for the EV RE20 I bought another one for the Shure SM 7B.Note:Usually I wait awhile to review. I've had the D1 for a few weeks now and I think that's long enough to do a review without any buyer's glee.

I love the fact that i don't have to use another cable like the "other" cludlifter, it goes directly to the mic, it does the job yes! But keep in mind a decent interface, I'm using a focusrite and works like a charm. My only down is, it looks weird (large?) you know that large stick behind the mic, but it's ok I prefer that instead more cables, I'm tired about so many cables on my desk.
