If you look around the internet for tips on how to reduce noise in your audio recording, you quickly stumble up on this “trick”: Turn down your gain and boost the recording in post. But this is not working at all and it can make things even worse!!!
It can be hard to tell if noise in your audio is coming from your gear or your recording environment. Here's how I'm making that distinction in my own recordings. All gear used is linked below and all my gear can be found at 🤍 I'm using a 150ohm resistor to measure the amount of noise coming from the preamps in the audio interfaces and recorders that I use to record audio. It's a tougher process to compare one preamp to another, you need to get more technical with it and in most cases my interests lay somewhere between technical and practical. For me, it's just helpful to know how much of the noise I'm hearing in any single recording is generated from noise in my environment vs. my gear. This dummy plug I made helps me do just that. Most consumer recorders and interfaces supply around 50dB of gain. When you use the dummy resistor to measure the preamp at 100% of 50dB of gain, you'll hopefully get a measurement that is no louder than -75dB avg. RMS. This should generally mean your device will not add any audible noise or any amount of noise you can't get rid of in post-production. But a better test is to plug in your microphone, set the gain to what you need to record a good level (-18 to -12db peak) and then insert the dummy plug and measure the noise floor. This number should be well below -75dB cause in most cases you won't be using 100% of the gain in your device. But even beyond the numbers, listen. You can now hear exactly the amount and type of noise your preamp is or isn't exhibiting. From there you can determine if this is an acceptable piece of gear for your productions and if you hear much more noise in your final recordings, then you have a good idea that it was coming from your environment and that you need to make some adjustments to your recording space if you want to reduce that noise.

How often have you plugged an external mic into your camera and wondered if the noise you're hearing is from the mic or the camera preamps? It could be either or a combination of both but since the goal is the best possible audio, it's important to test your gear to find the best noise floor result. In this video Sound Speeds Guest Host Barron Guillard shows you how to test your camera preamps so you can get the best results. It's also important to note that although Barron could record on a seperate recorder instead of the on top of camera mics but prefers the on camera option for many of his shoots. There are two reasons for this: 1) Less gear to be responsible for 2) Sound from the camera perspective always works great.

In this video you will learn how to test your camera's preamp self noise. Testing out your equipment and gears is a very important process. I highly recommend you to test out your camera's preamp this way, especially if you have noticed weird noise coming off of your lovely camera. Personally I use external audio recorders and I use the camera's internal mic as a reference audio, but to those who rely on camera's preamps, this is a great way to learn more about your camera.

Behringer UV1 microphone preamp noise floor test for analogue output using Tech Tone Stellar X2 & Sony FDR-AX100 camcorder. This is my first of the Behringer Ultravoice UV1 to see what its noise floor is like when using its analogue output. For the test I'm using the Tech Zone Audio Products Stellar X2 condenser microphone. I'm plugging the UV1 straight into the mic input of my Sony ZV1. This is actually not the best signal path or gain stage as the Sony has a mic input which even on its lowest gain setting is still a mic gain. So, adding a mic gain on to another mic gain isn't really the best way of gain staging. None the less, there is no other way of connecting and gaining for this type of recording setup. Part of this test is to test the noise floor of the UV1 when using only its preamp to connect to the Sony. The other part of the test is to re-gain the mic and switch in the processing signal path but without any active effects or processing. With both levels evenly matched, this will give a proper indication of the noise floor in bypass and with the processing chain switched in.

How can you tell if the noise (hiss) you are hearing in your audio is coming from your recording environment or your preamp? Test it! All parts and gear used to make this video at kit.co/rayortega Music by PremiumBeat.com. License this music: 🤍 Track: New Frontier by Flashing Lights Track: Poolside by Aulx Studio Track: Neons Eyes by Hartley If you want to measure the amount of noise that your preamp is adding or isn't adding to your audio productions, you need to measure the noise from the preamp separate from the ambient sound in your environment which is being picked up by your microphone. Making a 150 ohm resistor housed inside an XLR plug will allow you to plug into your audio interface and measure the amount of noise being produced by the preamp without being influenced by ambient sound of your room. This works because the 150 ohm resistor is equal to the resistance of the average dynamic microphone like the one I used in this video, the SM7B. So when you plug it in, the preamp acts like there is a microphone connected however there is no element to actually pick up sound from the environment and thus you get to measure only the noise that is within the device itself. The way I use this is quite practical in that I'm less interested in the specs/numbers produced by the measurement for the purpose of comparing one preamp to the next and much more interested in knowing how much of the noise in my recording is being produced from the environment or microphone that I'm using. If the noise floor of the preamp is well below that of the noise when the microphone is plugged in, I know it's not the preamp that is contributing to my noise and that if i want to reduce the ambient noise I need to treat the space I'm in and not that I'm using subpar gear. The build is quite simple and even someone like myself who hadn't soldered since he was a teenager was easily able to create this simple device.

Part 2 of a series showing repairs and modifications to an inexpensive, used preamp, the Gemini PA-7000. This preamp retailed for about $100 USD when new. The makers apparently kept the price down by 1) employing op-amp-based circuits (with no discrete transistors) and 2) using "jellybean" op-amps (4558's) in those circuits. The 4558 isn't bad, and of course it's cheap, but there are better options that are still relatively cheap. The 5532 would be a typical choice for a replacement, but the 2068 has measurably better specs and still has a low price tag, less than $1 USD. For most of the sub-circuits employing 4558's, noise is already undetectable, but the phono preamp sub-circuit provides a lot of amplification, produces measurable noise at the output, and is therefore the obvious place to upgrade the op-amp. TLDR: I measured a drop in full-volume hiss of 2 dB after replacing the 4558 in the phono preamp with a 2068. Please visit my second channel, where my latest Lancaster Hi-Fi videos are posted: 🤍

You can turn on English subtitles! Constant loop gain MM Phono stage-XXI (Su-XXI) by Nick Sukhov, with "aperiodic" HF correction invented by him back in 1980 [first described in the article "High-quality preamplifier-corrector" in the Radio magazine No. 3/1981 pp. 37-40, which became “The best publication of the year” in 1981] allows you to get rid of the input circuit resonance "MM head inductance + cable and phono stage input capacitance", due to which, above the resonance frequency (usually in the region of 14 ... 16 kHz), a frequency response decay is formed with a significant slope of 12 dB / octave ( like a second-order low pass filter). With aperiodic correction such a drop is eliminated and the sound of $50 MM cartridges becomes as transparent and detailed as that of top MC k$-priced cartridges. Similar circuit solutions appeared 20-30 years later among high-end Phono preamps under the names "Neumann pole", "Damped EQ", "Enhanced RIAA - eRIAA", "Phædrus Phlux active phono cartridge". Thanks to the original "passive cooling" solution with 150 kOhm input resistor instead of 47, the Su-XXI provides an unprecedentedly low noise level of -85 dBA in full compliance with the standard input level of 5 mV 🤍 1 kHz (and not the "maximum input" - a typical marketing trick) and with an equivalent input MM-source 500 mH / 1 kOhm connected (and not the "shorted input" - another trick of the steamers). Finally, thanks to the use of a high-output impedance voltage amplifier stage with a load Z(f) in the form of an RIAA-chain (overall gain 1+Z(f)/R, voltage amp open collector stage gain is also proportional to Z(f)+R, so loop gain is almost constant across the entire audio band), a "passive-active" frequency-correcting circuit is formed with an almost unchanged feedback depth from 10 Hz to 50 kHz (55 dB constant loop gain). This design of the deep RIAA freq response correction of 40 dB eliminates the “diseases” of both excessive gain at high frequencies and insufficient gain at low frequencies, which provides both a high stability gain margin (22 dB) and a uniquely low THD of 0.00006% at a nominal input voltage of 5 mV 🤍 1kHz and 0.0006% at +20dB overdrive. Add-ons and applications: What is "passive cooling" 🤍 Section of Su-XXI-v1 at Nick Sukhov Patreon: 🤍 PCB gerber files: 🤍 Datasheets of the main elements of Su-XXI 🤍 Clone of the "High-quality preamplifier-corrector-1981" using a modern components: 🤍 About Su-XXI power supply: 🤍 Electrolyteless Su-XXI version 🤍 Modification of the electrolyteless version of Su-XXI (DC output is no more than 1.5 μV!) 🤍 * Фонокорректор-XXI (Су-XXI) Николая Сухова благодаря изобретенной им еще в 1980м году "апериодической" ВЧ коррекции [впервые описанной в статье «Высококачественный предусилитель-корректор» в журнале Радио №3/1981 стр.37-40, ставшей лучшей публикацией журнала Радио за 1981й год] позволяет избавиться от резонанса входной цепи "индуктивность ММ головки + входная ёмкость кабеля и фонокорректора", изза которого выше частоты резонанса (обычно в районе 14...16 кГц) формируется спад АЧХ с значительным наклоном 12 дБ/октава (как ФНЧ второго порядка). С апериодической коррекцией такой спад устраняется и звучание 50-долларовых ММ головок становится таким же прозрачным и детальным, как у килобаксовых МС-головок. Аналогичные схемные решения появились спустя 20-30 лет среди хайэндовых финокорректоров под названиями "Neumann pole", "Damped EQ", "Enhanced RIAA - eRIAA", "Phædrus Phlux active phono cartridge". Благодаря оригинальному решению "пассивной охлаждёнки" ФК-XXI обеспечивает беспрецедентно низкий уровень шумов -85 дБА, причем в полном соответствии со стандартным входным уровнем 5 мВ 🤍 1 кГц (а не "максимальным входным" - типичной уловкой маркетолухов) и с подключённым ко входу эквивалентом ММ-источника 500 мГн/1 кОм (а не "закороченным входом" - ещё одной уловкой впаривателей). Наконец, благодаря применению высокоомного выхода УН с нагрузкой в виде RIAA-цепочки, сформирована "пассивно-активная" частотнокорректирующая цепь с практически неизменной глубиной ООС от 10 Гц до 50 кГц (постоянное петлевое усиление 55 дБ). Такое построение схемы RIAA-коррекции с глубиной 40 дБ избавило от «болезней» избыточного усиления на ВЧ и недостаточного усиления на НЧ, что обеспечивает как высокий запас устойчивости (22 дБ), так и уникально низкие нелинейные искажения 0.00006% при номинальном входном напряжении 5 мВ 🤍 1 кГц и 0.0006% при перегрузке +20 дБ.

DM1 - DYNAMITE 🤍 Some mics need a LOT of gain - and not all preamps are up to the challenge. The DM1 DYNAMITE is an ultra-slim active inline preamp that fits seamlessly between your mic and mic pre, providing a massive +28dB of clean, transparent gain for all your dynamic and passive ribbon microphones - perfect for podcasting, recording, or live sound. With a sophisticated class-A design and specially-selected high-grade FETs, the DM1 has vastly lower output impedance and nearly half the noise of anything else on the market. Additionally, the gain it provides is always a consistent +28dB regardless of the connected load, thanks to its dedicated buffer amplifier. Whether you’re a podcaster, recording engineer, or running live sound, the DM1 is the perfect way to boost the signal from a passive mic, reduce the likelihood of interference, and provide significantly improved level to your preamp – all without adding noise or coloration. Its output impendence is also the lowest in its class, allowing it to drive long cable runs while reducing susceptibility to RF interference, buzz and hum. Reliable operation even in demanding on-stage applications in difficult environments is ensured by the roadworthy and slim all-metal design, robust construction, and high-quality manufacturing standards.

In this video I have designed, build and test two mic preamp circuits. I also briefly describe the circuit diagram I have come up with. Comment below if you spot any possible improvements :-)
More DIY audio electronics, this time we're building the ESP Low Noise Balanced Mic Preamp from Elliott Sound Projects: 🤍 With my new audio interface I want to take advantage of all 6 analog inputs to record nice multitrack drum stems, so I'm adding 2 mic inputs with this preamp project. It's powered by 12V AC and should add two low-noise clean channels for dynamic microphones. I struggled mightily with this build so hopefully I can provide some insight to anyone else building this project! Here's the song I recorded for the demo at the end: 🤍

The UM2 is an inexpensive USB interface for microphone and other line level devices (guitars, keyboards, etc), but for the ipad to use it, it needs to go through a USB powered hub, where it picks up a bit of hum due to the leaky power supply - here I add a ground to the signal sleeve directly to the third pin of the AC wiring to help dissipate this noise
