This particular circuit application has 2 mic inputs and 2 line inputs. You can add more inputs by connecting the same in parallel which simple audio circuits it a simple audio circuits channel audio mixer circuit.

Passive tone control circuit — This is a simple tone control circuit that you can make with components available at your hand.

Build a Great Sounding Audio Amplifier (with Bass Boost) from the LM

Simple audio circuits only active component in this circuit is an op amp TL The circuit is named passive because the tone control section is completely handled using passive components.

A really low cost and easy to build audio circuit to try your hands on. This IC from National Semiconductors requires very few external components and has a built in mute facility.

See the figure below. Speakers in parallel behave the same as resistors in parallel.

An Introduction to Audio Electronics: Sound, Microphones, Speakers, and Amplifiers

Frequency response, an important speaker characteristic, represents the frequency range over which a speaker can successfully propagate sound waves. Such a three-way speaker system is illustrated below.


Preamplifier Low-power amplifier Power amplifier An audio preamplifier often shortened to "pre-amp" is an electronic device that simple audio circuits a very weak signal from a microphone, as an example, into signals strong enough to manipulate. Pre-amps are often simple, fixed-gain amplifiers designed specifically for low-noise performance.

A list of Simple audio circuits and amplifiers for DIY(Do it Yourself)

A low-power amplifier is often used to manipulate signals including such aspects as volume and frequency equalization. This type of amplifier simple audio circuits focuses on changing the character of the signal in desired ways while introducing as little unwanted distortion as possible and may provide little to no actual power amplification.

An audio power amplifier "power simple audio circuits is used to increase the signal power so simple audio circuits to drive a load, such as output speakers. Similar to pre-amps, power amps are often fixed gain in terms of signal amplitude so that designers can focus on high-power gain and the power handling challenges that typically result.

In simple audio systems where high power and high fidelity are not critical factors, a single-amplifier circuit may perform all of these functions, and, in fact, specially designed operational amplifiers, such as the LM Low Voltage Audio Power Amplifier, are often used this way.

The datasheet has graphs that will simple audio circuits you. I used a 9V battery for the power supply and it works great, but you can go down to 4V or up to 12V.

  • Build a Great Sounding Audio Amplifier (with Bass Boost) from the LM386
  • A Minimal LM386 Audio Amplifier

Operational amplifiers have a basic task. Simple audio circuits lets you adjust the sound level within the range of amplification set by the gain.

For example, if your gain is set to 20, the range of volume is 0 to
