Stereo Preamplifier Circuit with Bass Treble Control

This simple, one-chip, stereo preamplifier is ideal for build-ing into an existing AF power amplifier. It is based on a re- cently introduced integrated circuit, the Type TCA5500 or TCASSSO from Motorola. This double AF amplifier chip with inputs for balance, volume, and bass and treble controls forms a sound basis for a good quality […]

Digital Volume Controller Circuit

The circuit shown here is based on the switching action of transistors. Volume of a stereo deck can be controlled with the help of a potentiometer which changes the resistance between the output of the preamplifier and input of the amplifier. This can be done with the help of decade counter, IC.4017 and some transistors. […]

Simple Logarithmic Amplifier Circuit

The performance of the logarithmic operational amplifier, the circuit diagram of which is shown in figure 1, is best seen from its input/output characteristic shown in figure 2. For small input voltages, the amplification is high; when the input voltage rises, the amplification drops off and finally remains almost static for further increases in input […]

Constant Volume FET Amplifier Circuit

In numerous occasions it is desirable to obtain an amplifier that gives an output signal of constant amplitude for numerous input signal levels and with the very least distortion. A traditional way out of this challenge is to use a nonlinear amplifier. An operational, as an illustration, run as a nonlinear amplifier if 2 antiparallel […]
