I decided it was time to build a preamp to aid in testing power amps and for other uses on the bench. If you build one for audio use, I'd recommend adding 100 ohm output series resistors to keep the amp stable when driving capacitive loads such as shielded cable runs.

Disclaimer: These transformers are around $2 and the frequency range is 300Hz to 10,000Hz. This video illustrates the concept of using transformers to passively increase the voltage output of a device like an Ipod. If your application needs a frequency range of 10Hz to something over 18KHz, then you need to purchase Sowter or Jensen audio transformers ($80 a piece and two are required). This passive preamp doubles the 2.8V audio output signal to 5-6 volts which is typically required for any AUX input on a car or most inputs that state CD input. An IPOD or IPhone is designed for 2.8V to save battery power and to drive the typical IPOD ear buds. However, to drive a 5volt input, you have to turn the IPOD volume ALL THE WAY UP. When you forget to lower the volume before plugging back in your ear buds, well, you get an unpleasantly LOUD VOLUME BLAST. This device will allow you to switch between an ear bud and a AUX (or CD) input device using only half the volume of the IPOD.

This circuit is part of a larger project, consisting of a 400W amplifier, with tone controls and microphone input. One of the great advantages of this circuit is that we can place the volume control up to 30 meters away from the amplifier, without any noise being introduced.

You might not have enough room under your pickguard for the extra wiring or battery, or your bass just may not have a pickguard. So to be extra thorough, I'm gonna show you a mixture of both! Start by planning out your installation. Choose where you want your extra knobs and switches to go. Keep in mind how much wire length you have, and where you're going to put your battery. I'm going to install the preamp and switch into the body, and the battery under the pickguard. Before I start drilling and routing, I like to cover the component cavities with tape while I'm doing this so that no unnecessary saw dust ends up in there. Now. match up your components to the appropriate size drill bit, and drill holes for your components in the place you decided for your install, either in the body, like me, or in your pickguard. If you're installing it in the body, you'll need to route out some material from the back of your bass in order to make room for all your components. Don't worry, we will make a nice cover plate to hide the new cavity later. If you are installing everything under your pickguard, you can skip this step entirely. For routing, I'm using my dremel tool with the multi purpose cutting kit just like I did for the extra pickup cavities in this bass. Dremels are not expensive, this one was only $20, and it's an awesome investment, so pick one up if you don't have a router already.. You'll get way more use out of this thing doing other tasks than you will with a standard router that costs 3-4 times the price. I put a link in the description for you. Next, drill a hole from your new cavity into the existing component cavity that houses your volume and tone controls so that you can feed wires thru between the two cavities. Last thing before we start wiring this thing together, I'm going to quickly make a cover plate. You can make this out of the placard material used for pickguards, but I like to make mine out of wood, so I picked up this small plank of 3/16 basswood from my local craft shop. Just make an eyeball measurement of how big it needs to be to cover your cavity, cut it to size, and an optional step for a cleaner look, route out a thin area the size of the cover plate so that it can mount flush with the body. Not necessary, just looks a little nicer and more professional. Last I like to paint or stain the new cover to match the body. Okay now we can wire it up. ...continue reading the blog version at gunsandguitars.net

This is Part 1 of a two-part video series discussing (in very basic language) virtually all aspects of tube amplifier (passive) tone controls. Topics covered: 1.) The differences between active and passive tone controls 2.) Different locations for tone controls within the amp circuit, including benefits and drawbacks of each 3.) The use of a cathode follower to match impedance between circuit and tone stack 4.) Capacitor theory regarding AC/DC response and frequency passage 5.) High Pass and Low Pass Filters....design and function. This series is in response to numerous requests and is best suited for those who seek a basic understanding of amplifier design and function. The tone is conversational and, as usual, relies upon simple language, analogies, and explanations. In addition, Rusty makes a couple of appearances and his nemesis, the Cat, is offered his job behind the camera......with somewhat predictable results :) If you enjoy videos featuring classic vintage tube amplifiers, jukeboxes, home-built electronic marvels, and basic, understandable technical presentations, then please subscribe to my channel.

How to use the inverting operational amplifier circuit as a summing amplifier or audio mixer. This configuration is often known as a virtual earth mixer. The inverting operational amplifier or op amp circuit has a virtual earth point and this can be used to enable a variety of signals to be summed or added together. The virtual earth mixer or virtual earth summing amplifier using op amps has been widely used in many applications including audio mixers, analogue computers as an adding or summation block, and in any area where analogue voltages need to be added together or summed. The video provides the equation or formula needed to calculate the gain of each input. The inverting amplifier summing amplifier is ideal for many applications, but some precautions need to be remembered when using it. Several hints and tips are given that have been gained from practical experience as a design engineer.

Power amplifiers for home theater use as well as 2 channel audio listening require a specific amount of voltage gain to operate within a quality set of perimeters. Each power amp and pre amplifier paired together impose a specific amount of power together determining how your stereo will ultimately sound. This video shows how to understand what power amp specifications one should consider before buying or using with preamps. Each and every pre amp or pre out section on any receiver emits a certain amount of voltage sent into the power amp, if that number is not an adequate amount of V RMS then the pre amp can be sending clipping signals into the power amp.

LINKS TO AUDIO FILTER VIDEOS IN THIS TEXTBOX. Do Germanium transistors and Silicon transistor each have their own "sound color"? In this video I test the difference between a AC 187 (NPN Germanium) and a BC 547 (NPN Silicon) in an audio pre amplifier (approx. 0,3 % distortion). Take your own conclusions about possible sound "coloring" and/or do your own tests with different NPN Silicon and Germanium transistors with this circuit. Much more audio in my book "Schematics 2, audio amplifiers and loudspeaker boxes" (author Ko Tilman) on the Lulu website. By the way: I am almost sure that a germanium transistor audio amplifier has another sound color, compared to a silicon transistor amplifier. This is based on my experience and listening. The question is: which sound do you like? And/or: it is possible to give a Silicon amplifier a sound (with tone control) that resembles the sound of an (old) Germanium audio amplifier.

This video shows that you can connect a pair of passive speakers directly to the Headphone output of a computer or a laptop or any other headphone output. Passive speakers don't have a built in amplifier or another external power amplifier. The speakers in this video are the Turbosound impact 55, 16ohm/100w (of course they will not run anywhere close to 100w as a headphone amplifier averages somewhere between 0.5 and 2 watts. When I say minus in the video I mean "negative" and plus is the "positive" wire. The negative wires (-) from the speakers are joined and connected to the ground of the jack plug, one positive (+ left) to the tip of the jack and the other positive (+ right) to the ring of the jack. With 16 ohms speakers is safe as there are many 16 ohms headphones out there. With 8ohms, it should sitll be ok, it will heat up the internal headphone amplifier, it will also sound louder, but 4 ohms speakers could put some serious strain on the headphone amplifier so I wouldn't recommend them. It will also sound distorted at high levels. The sound quality in my case is very very good, but these Turbosound speakers were pretty expensive when new. There are many good speakers you can find that are better priced, especially used. Some examples of speakers: Apart SDX, SDI, SDQ, Ovo passive series JBL control (if you find the 100volt/16ohm version but 8ohm would do) Adastra

The main limiter is device parasitic capacitance and inductance, either in the attenuator itself or in it's support circuitry. The most basic attenuator is a relay with a resistive divider network. The bandwidth is limited because there is a long signal path required. A solid state attenuator is often good up to several GHz. They use GaAs MESFET with stepped attenuation. They are similar to a MOSFET, and if the device is on it provides near zero impedance, and when on it switches to high impedance. The bandwidth can be limited by capacitance. At higher frequencies, the higher frequency components can "blow through" the capacitors and the attenuator becomes less effective. The other limitation is that it has a voltage limit. With too high of a voltage, the system can be non-linear or even damaged. For the highest bandwidth oscilloscopes, a coaxial stepped attenuator is used. It uses an RF input and gives the appearance of 50 ohms up to very high frequencies. --------------------- Preamps --------------------- SiGe BiCMOS bandwidths go up to 30 GHz depending on technology node and packaging. A standard QFN can go up to 8 GHz, but with custom IC packaging you can get much higher using custom launches and bypass circuitry. The impedances are also much easier to control. For very high performance, InP HBT preamps can be used beyond 50 GHz. Indium Phosphide processes allow you to design very fast transistors that are faster than germanium doped silicon. --------------------- Links --------------------- Twitter: @Keysight_Daniel https://twitter.com/Keysight_Daniel Learn more about using oscilloscopes: http://oscilloscopelearningcenter.com Check out the EEs Talk Tech electrical engineering podcast: https://www.youtube.com/playlist?list=PLzHyxysSubUnAMeCIi2-S0Vm7YtSAGqx_ The 2-Minute Guru Season 2 playlist: https://www.youtube.com/playlist?list=PLzHyxysSubUlqBguuVZCeNn47GSK8rcso The 2-Minute Guru Season 1 playlist: https://www.youtube.com/playlist?list=PLzHyxysSubUkc5nurngzgkd2ZxJsHdJAb More about Keysight oscilloscopes: http://bit.ly/SCOPES Check out our blog: http://bit.ly/ScopesBlog Like our Facebook page: https://www.facebook.com/keysightbench/ #tutorial #electronics #oscilloscopes #oscilloscope #engineering #design #IC #ASIC #electrical #test #preamp #attenuators

Audio Builders Workshop will be unboxing kits and DIY audio parts, and tools from Collective Cases, DIY.RE, Microphone-Part, JLM Audio, Hairball, Expat Audio, Bumblebee DIY Pro Audio, Austin Microphones, Audibility Recording, GKL gKit Baby / ORA, Vintage Microphone PCB Kit, Sparkos Lab, Geistnote and many more! Elements is built on the classic single op-amp, transformer coupled microphone preamplifier circuit found in many classic console designs. A discrete op-amp in the standard 2520 footprint provides variable gain, while the input and output transformers perform a wide range of functions including circuit isolation, impedance matching, additional step up gain, and in some cases much of the tonal color. The EQP5 is a premium tone-shaping EQ based on the prized Pultec EQP filter circuitry. The World's Most Musical Filters. The EQP5 employs the passive filter circuitry made famous by Pultec's legendary EQP series of equalizers. Decades after their introduction, these EQ's remain coveted for their uniquely musical and natural behavior. Modern Clarity or Vintage Tone. Choose between a clean and modern or vintage and colored output stage. If both outputs are installed, you can switch between them with a solderless jumper on the board. The Modern (stock) output is a clean, robust, balanced output for excellent noise performance. Choose this output to use the EQP5 for transparent, natural tone-shaping. The Vintage (optional) output employs a DOA (discrete opamp) and custom transformer for a livelier dynamic character. The vintage output gives signals a more visceral, forward feeling that helps them translate clearly in a mix while requiring less level to do so. The solid-state Pultecs, the sound of which many engineers claim to be sweeter than that of the earlier tube units, use the same DOA/transformer output scheme. Designed for DIY. The EQP5 was designed from the ground-up to be a satisfying DIY project. Our photo manual will guide you through every step of the assembly. And the circuit board contains extra capacitor and inductor footprints for customizing the frequency bands.
