Once the transformer core saturates, distortion rises very fast to an unpleasant or even unusable level. The proximity effect that Neumann TLM 103 brings creates a huge bottom when used … 5.0 out of 5 stars. Transformer balanced microphones tend to have a slightly thicker bottom end and a slightly airy top end. But the fact is that there are hardly any microphones which are offered in both transformer balanced and transformerless versions. In fact, transformers often show a slight resonance above 20 kHz, which gives the top end an airy feel. You may run into distortion when you record drums, but, as stated before, it may not be the kind of distortion you want. The TLM 103 is part of the FET 100 series of condenser microphones from Neumann. ", another really good way to tame the tlm103 with a sm7 windscreen is to just use the sm7 and sell the tlm103. the TLM 103 is picky. There are hardly any transformer balanced microphones that can be used on a kick drum (one famous exception being the Neumann U47 fet, which has an unusually big transformer). But what you do get is a perfectly designed grill, beautiful body and one of the best capsules manufactured on planet Earth. On the microphone (or any other balanced output), the audio signal is referenced between the two signal lines. Neumann considers it a low-budget microphone, although its street price is about $1000. My electronics knowledge says I can't answer that! Unbalanced outputs, as for instance on an electric guitar, have only one signal line plus the cable shield. Skip to main content. Transformers may also have a slight resonance at the lower end of the spectrum, which may indeed give the impression of a fatter bottom end. There are several ways to achieve a balanced output. I expected Brent to pop in and say "replace it. Here’s how it works: If, for instance, a microphone cable runs near a power line, its AC current will induce a small current, i.e. Which preamps are you using? Transformerless microphones (such as the Neumann TLM 103) became popular much later in the 80s and 90, when most engineers wanted a brighter, more modern sound. As a result, transformer balanced equipment has resurged in popularity. maybe you can tape it over the tweeters of Yamaha NS10s! That’s because balanced signal lines reduce interference due to external electric fields. When transformers were at every stage in the audio path, their sound coloration was considered a bad thing. Balanced means, there are two signal lines and a separate ground connection, usually the cable shield. Not only because it promised less sound coloration but also because of reduced costs. Always keep in mind that least 90% of a microphone’s sound is in the capsule! But i think i found a solution... You know that thick windscreen that comes with the Shure SM7B that nobody ever uses? Is something wrong with me? This technique was very convenient for tube and early transistor electronics, because the transformer could also be used for the final part of the impedance conversion. While other electronic components such as transistors or op-amps have become cheaper over the years, high quality transformers have remained expensive. Especially when it comes to microphones. The sound image also appears slightly less direct. The TLM 103 offers everything demanding users could wish for: nuanced vocals with precise reproduction of sibilants and excellent speech intelligibility. That wouldn’t work with a condenser capsule because it requires electronic circuitry to convert the ultra high impedance capsule signal to a low impedance output. Off-axis sounds are rendered naturally while isolation is increased. The … Depending on who you ask, you’ll get different responses. ... Neumann TLM 103 Large-diaphragm Condenser Microphone - Nickel. Unlike the legendary U87, the TLM 103 uses an electronic circuit rather than the usual output transformer. ... electrically and electronically balanced preamps. Many engineers couldn’t be happier. Since the hum noise is induced in both signal lines equally, there’s no difference in hum voltage. This also leads to a high feedback suppression when the microphone is used in live situation… The Neumann TLM 103 is the ideal large diaphragm microphone for all professional and semi-professional applications requiring the utmost in sound quality on a limited budget. You won’t hear it, though, because your microphone preamp is what is called a differential amplifier: it amplifies the difference between both signal lines. EQ and Compressor bypassed on the shelford BUT a touch of red silk. The TLM103’s capsule, called the K103, is “based on the K87, well known from the U-67 / U-87 microphones.” Big sound in a small package. a 50/60 Hz hum, in both signal lines. Transformerless microphones (such as the Neumann TLM 103) became popular much later in the 80s and 90, when most engineers wanted a brighter, more modern sound. Transformer distortion produces mostly uneven harmonics, and it’s not very gradual either. It’s very easy with dynamic (moving coil) microphones: The two signal wires of the capsule are directly wired to XLR pins 2 and 3. To understand this, you have to consider the fact that at that time transformers were everywhere, not just in microphones. But what does it mean, and how does it affect the microphone’s sound characteristics? Can You Tell The Difference? TLM 103 provides a dy-namic range of 131 dB, according to DIN/IEC 651. The TLM-103 is a FET amplified, transformer-less balanced microphone, no fancy tubes or pieces of iron in here! However, transformerless microphones usually have a more extended response both in the high and the low frequencies. Audio transformers do indeed color the sound image, but not as much as people tend to think. Already have an account? You need an account to post a reply. A single tube or FET did the first stage, and a step-down transformer did the second stage of the impedance conversion. My electronics knowledge says I can't answer that! The sound character of the TLM 103 … Is that another way of saying "with and without transformers?". In reality, a well designed audio transformer is able to transmit frequencies beyond the human hearing range, so it does not limit or smooth out the treble response audibly. As the effect, Neumann TLM 103 sounds cleaner and rather brighter than Neumann U87. Well i finally found a use for it! Audio transformers were considered outdated technology which – potentially – stood in the way of the most direct sound experience. Just a friendly reminder that political discussion, (including "offhand" and 'sideways' commenting) is, I always see people complaining how the Neumann TLM 103 can be overly bright and on the strident side. Brand New. Create a username and password below and an account will be created and your post entered. Transformer balanced microphones are said to offer smoother top end and deeper bottom end. So your preamp only amplifies the microphone signal, which is between the two signal lines, but not the 56/60 Hz hum which is equal in both lines. As it is capable of handling sound pressure levels up to 138 dB without distortion, the TLM 103 provides a dynamic range of 131 dB (A-weighted). Today, the TLM 103 defines the standard by which contemporary studio microphones are measured. But some engineers, mostly in the pop/rock/hip-hop scene, feel that this super-transparent sound is a bit bland and long for a touch of that good old “vintage” tone. Traditionally this was done by means of an output transformer. The letters TLM stand for “transformerless microphone”. Made a video below showing what it looks like LOL. Microphone spec sheets usually tell you if the output is transformer balanced or transformerless. And, more importantly, transformerless microphones can take much more level without distortion. Audio transformers do color the sound somewhat, but to a much lesser extend than people think. Hey there! Clever, isn’t it? Studio microphones always have a balanced output. An electrical audio signal always requires two connections, so on the guitar the output signal is referenced between the signal line and the cable shield. Studio sound on stage. The TLM 103 is a fixed-cardioid, large-diaphragm FET microphone intended for the project-studio market. Back then, a typical broadcast console contained dozens, sometimes hundreds of audio transformers. This calls for the ART Tube MP, THEE Pro solution. It was around this time that Neumann introduced its TLM series (TLM = transformerless microphone). The letters TLM stand for "transformerless microphone". This allowed for very simple circuits consisting of very few components. Many transformer balanced microphones (such as the Neumann U 87) date from the 60s and 70s, when most engineers preferred a rather mellow kind of sound.
