Hello. im going to make this mixer circuit.Im not sure if it work fine or not.Can you please check it for me ? Thank! In this schematic, i use R1=R2.... -
This Audio Mixer mixes multiple audio inputs to a single audio output, with knobs to control the volume of each channel. My particular build features.... -
The circuit schematic below represents one method for the design on an audio mixer. The active component is an LM318, although basically any operational amplifier would work in its place. The circuit is the classic design for an Op Amp summing amplifier..... -
In this project, we will build an audio mixer, which is a device that can add different audio signals together into one output. For example, say, one audio input is a cappella, with a personG ‚¬ s lone voice singing and another audio signal is background.... -
If resistors R1 to R4 are variable, the signals can be mixed in any proportion, meaning at any volume levels. And overall volume can be set by a variable resistor in series with Rf. .. -
The target of this project was the design of a small portable mixer supplied by a 9V PP3 battery, keeping high quality performance. The mixer is formed assembling three main modules that can be varied in number and/or disposition to suit everyone needs. The.... -
This project is an older design and has most likely been superceded by a newer one. However, it is still a viable design and useful for your home-brew synth. Sorry but most of these do not have circuit descriptions, parts lists or PC board layouts (They.... -
An audio mixer is a handy circuit that will combine two or more audio signal sources into one signal channel. The figure shows an audio mixer that is built around the LM3900 CDA. The crux of this circuit is the three input networks, principally R3, R4, and.... -
The basis of an audio mixer is an inverting summing circuit below. For real audio mixers, a single-supply voltage is seldom used. To increase dynamic range,.... -
The figure shows a basic two-channel op-amp mixer circuit. The gain is equal to R5/R1 or R5/R2 for channel 1 or 2, respectively. Typically R1 and R2 are 2. 2 to 22 k © and R5 is 10 to 100 k ©, and the op amp is any suitable type, such as a 741 or its.... -
Designed around an LM3900 quad op amp, this mixer combines 2-line and 2-mike inputs and sums them at the output terminal. R7 through R10 can be changed to vary the gain (around +23 dB). .. -
The circuit has four inputs. The voltage gain between each input and the output is held at unity by the relative values of the 470k © input resistor and the 470k © feedback resistor. .. -
Uses two separate common-cathode video mixers. Same heading markers are inserted into both mixers front input 2, while other inputs handle independent markers. -NBS... -
Negative video plus iff signals are inserted at grid, while range strobe, from cathode output of blocking oscillator, is applied to cathode. -NBS, "Handbook Preferred Circuits Navy Aeronautical Electronic Equipment, " Vol. 1, Electron Tube Circuits, 1963, p.... -
This one transistor audio mixer is used in an amplifier circuit design with base driven transistor and with its emitter being current controlled, most of the driving current flows through the collector away. Using the values in the audio mi.... -
Here the simple mixer with 4 input and 2 op-amps: A basic mixer suitable for mixing microphones or even effects outputs. The overall gain from input to output is one if the pot related towards the input is full up. You can make this a net g.... -
Because of this audio mixer, I can compare the various receivers just by twiddling the gain controls. No switching required. Makes A/B comparisons a snap. (They are all driven by the same antenna). All of this used to be easy I just used a different speaker....

This project fits more for custom made battery casing that can have more space to hide things inside. This switch with few alterations can be used for any other project as well but is designed based on e-bike needs! This project use a clever functionality of.... -
The circuit described here uses ultrasonic oscillations and operates based on the propagation velocity of these oscillations in the air. Thus, we can easily determine the distance of two points if the time within which the wave travels this distance is.... -
Sometimes the precious metals are hidden too deep and are not detected except with complicated devices. In many cases, however, small pieces of precious metal buried near the surface can be detected by relatively simple means. Everyone is very attractive to.... -
Many times for various reasons we forget or can not water the plants that we have in our homes. And many humidity sensors units just notify us with a beeping sound or with a flashing light, that the pot needs watering. But what if we are away from home? This.... -

The sub-harmonic bass generator is a sound producing unit for guitars. The sound it produces looks very much like that of the bass guitar. The octave generator is sometimes quite unusual since it does not produce any of the usual ways of coloring the sound,.... -
In the past the sounding (sea bottom measurement) was done with the "bullet", that is, with a heavy lead object that the seamen plucked into the sea hung from a calibrated rope. As soon as the "bullet" reached the bottom, the depth appeared directly from the.... -
This Amplifier was designed to have the following specifications: Distortion less than 0.1% at full power of 100W even at 20KHz. Power has to be attributed to an extended bandwidth. The output transistors must be protected against short circuits. The power.... -
A series of LEDs serve to alert the gardener when plants need water. Using two conventional digital integrated LEDs and a series of LEDs, we make a very useful device for gardening. The device detects the amount of water in the pot and alerts the grower.....
