    This video was a life saver. I recently got a good deal on an early-ish 441 but the xlr jack was very loose. Using this video I popped the badge off and found that the set screw needed to be tightened the tiniest bit. Less than a quarter turn later and everything feels like brand new without needing to tear the whole mic apart. Thanks! Also, agreed this mic is really Excellent sounding.

    Oh Dave. You have just killed me. Back in the day... 1983. We had 58's and Beyer M88. We also had one 441. It did ALL duties. We did a gig for a proper guy called Richie Havens. We put the 441 on his voc. His 'people' loved the vocal sound... and the whole rig. My brother and I were worried that 441's physical GRAVITAS would faze Richie. He did not give a toss. Thank you Dave for making my day. 😊❤️😊

    This is one of my all-time favorite mics. I’ve had 4 since I began my career in 1976 and they are in constant use. They sound beautiful, look beautiful and have the ideal polar pattern for just about any application. Vocal, drum, acoustic strings, bass, ek guitar, audience, any soloist. Really, a supermic.

    I bought 6 of these from a radio station that closed back in the late 90s and all of them are in working order, I always used them as drum tom and snare mics in the studio but I never considered taking them out for live shows for vocals. I like them on drums because the rejection is insane and only rivaled by the 609 and 906 mics from Sennheiser, but the 609 & 906 don't have the clarity or fullness that the 441s do.

    Found one years ago in a pile of audio junk and 02r expansion card in a control room inside a small music school. It belonged to the audio engineer of the band that started the school and concert venue right across the street. I didn't know much at that time, it looked like a old trash mic like the 10 other legit trash mics I found. Imagine my suprise after looking it up online ! The high pass filter is broken (spins endlessly) thankfully not on the highest cut setting. Is it hard to change (regarding the tiny wires) ? I have used it and really liked it live on bass cab mainly and in recordings with bass, guitar electric and acoustics, and lots on vocals for metal and punk. Amazing mic, I just wish I had a damn mic clamp to use it properly. I opened it up one time and was mesmerized by the srping dampening system and how complicated it looked, compared to "regular" dynamic mics. And thank you very much for being on youtube Dave

    Very interesting video ! The Beta58's top end sounds a bit harsh in comparison with the MD441. The Sennheiser has a "warmer" quality to it. You're right: it sounds almost like a condenser mic. I wonder if this has to do with the amount of compression from the capsule. I think condenser mics compress sound more than dynamic mics, resulting in a more pleasing sound. It would be interesting to compare the feedback sensitivity between both microphones. Microphones are fascinating works of engineering. I would love to see the same kind of video with the AKG D12.

  • @DaveRat

    @DaveRat

    2 жыл бұрын

    Dynamic range is sort of like top speed, transient response is like acceptation. A dynamic mic tends to be more like a heavy car that can go faster and a condenser is like a lighter weight car that can accelerate and brake much faster. Condensers tend to be more accurate at capturing the sound. Dynamics tend to blur the sound and add more resonances but because they do not rely on electronics, many can handle sounds at higher levels. That said, both mic types will become more non linear with higher level sounds, but the higher level sounds areore likely to distort the electronics built into most condensers. That said, building a condenser that handles high level sounds is quite possible, like the beta98, but the cost is they tend to be noisier with low level sounds.

    The polarity and phase or delay of the connections for front and back would determine the pattern. Opposite polarity would be fig 8, same polarity would be Omni. And by altering the delay and phase, cardioid, super cardioid and hyper are possible. So it depends on the electronics

    Hi Dave, thank you so much for this awesome video which finally gave me the knowledge and confidence to open a very old 441 (with that enormous Tuchel connector from the early seventies) my father handed over to me some years ago. Although it still has some output it did not sound like a quality mic at all, so I never used it. Now I found out that the round foam pad on the front end was completely rotten and some of the debris covered the diaphragm. I have removed that crap with an air cleaning rubber ball for camera objectives but now have to replace the foam. Do you have a recommendation which foam I should use for that? Thanks in advance! Best regards Chris

    Oh my, never worked with one of those. I'd start with making sure the mic works. Maybe removing the mic capsule and touching the conductors to see if you hear a buzz of click. If ya hear a buzz or clicks then maybe a bad capsule, if not, it gets more complex

    Hi Dave, thanks for the great video. My name is Jeff from Australia and I have an old 441-U which is not working properly. It basically sounds thin and I'm sure it's not meant to. I inherited this from my brother in this state many years ago. Watching your video inspired me to take it apart and you're right the wires that connect from the main body to the part where the HP filter switch is....Well I needed to be a little more careful with it and I've broken them off. Anyways in doing this I've noticed there are only two thin wires connecting through to the part where the XLR plugs in, and I'm under the impression there needs to be three. Could you please clarify if this is the case and whether this would cause it to sound thin ?? TIA. PS I also need to know where the wires go back and given one is too short can I get that wire anywhere and try and splice???..Regards Jeff

    @@DaveRat thanks so much that makes me happy as it's a step closer to fixing it in knowing that may have affected the sound. I'll need to try and work out if the third wire which wasn't connected is still there and if not then where on the switch it comes from. I remember you saying there is a blue, green, red and yellow coming into the switch so I'll also need to know which pole on the switch the third wire comes from and if it's not there I'll try and source some ultra thin wire. I noticed the first short screw you took out that holds it together in mine has been replaced and it goes all the way to the other side of the chassis so who ever has worked on it before may have lost the correct one and also disregarded the wire. Cheers again Dave 🤘
