A microphone preamp circuit is used to amplify a microphone’s output signal to match the input level of the devices following it in the signal chain. Matching the peaks of the microphone’s signal ...

The circuit was based on a single operational amplifier integrated circuit that is made to produce a modular preamplifier which functions in the Class A operation Preamplifier (pre-amp) – a device ...

Circuit simulations are great because you can experiment with circuits and make changes with almost no effort. In Circuit VR, we look at circuits using a simulator to do experiments without having to ...

In a balanced op-amp circuit, the op-amp inputs see equal impedances looking into the circuit. Balanced circuits provide better performance by cancelling some input errors and have a simple R F /R I ...

At $1,999, the Technics HA-507 is a pure analog headphone amplifier and preamplifier with a balanced/dual mono configuration. Although TEAC’s Reference 500 series includes UD models that combine both ...

Andy recommends favorite resources for basic op amp circuits and includes a portion of TI's AN-20. Test your knowledge with our op amp quiz; answer explanations are included. By 1969, a fledgling ...
