Microphone Pre-Amplifier with Variable Compression and Noise Gating Project Using SSM2166

Leave a comment

The SSM2166 integrates a complete and flexible solution for conditioning microphone inputs in computer audio systems. It is also excellent for improving vocal clarity in communications and public address systems. A low noise, voltage-controlled amplifier (VCA) provides a gain that is dynamically adjusted by a control loop to maintain a set compression characteristic. The compression ratio is set by a

Dual DC Operated Tone/Volume/Balance Circuit Using LM1036

Leave a comment

Dual DC Operated Tone/Volume/Balance Circuit The LM1036 is a DC controlled tone (bass/treble), volume and balance circuit for stereo applications in car radio, TV and audio systems. An additional control input allows loudness compensation to be simply effected. Four control inputs provide control of the bass, treble, balance and volume functions through application of DC voltages from a remote control
