SE Electronics DM1-MIC-PRE Dynamite Active In-Line Preamp

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

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

impressionante qualidade de som, gigantesca!

I bought this on recommendation from a friend. He did not lead me astray; it works EXACTLY as advertised. The noise floor is silent. I'm using with a SM57 & Yamaha MG10XU mixer. No more having to have everything on 10 to barely be heard during live streams. It gives the SM57 the exact bump it needs. Easy 5 stars. Get one, they are killer.

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.
