10 W Bass-boost Audio Amplifier Schematic Description: This architecture is based on the 18 Watt Audio Amplifier, and was developed mainly to amuse the requests of correspondents clumsy to locate the TLE2141C chip. It uses the boundless NE5532 Dual IC but, obviously, its ability achievement will be comprised in the 9.5 – 11.5W range, as [...]
Audio Equalizer 10 Band Schematic This circuit allows you to equlize the audio signals in ten band. It uses low amount op-amps to anatomy a able blaster circuit. The affection of the architecture is a classical band-pass alive filter. The U11 acts as an attenuator to adapt the arresting akin for equlizing. The U13 acts [...]
Mosfet 300W Audio Power Amplifiers Schematics Mosfet 300W Audio Power Amplifiers Schematics Specification: Maximum Output: 240 watts rms into 8 Ohms, 380 watts rms into 4 Ohms Audio Frequency Linearity: 20 Hz – 20 kHz (+0, -0.2 dB) Closed Loop Gain: 32 dB Hum and Noise: -90 dB (input short circuit) Output Offset Voltage: Less [...]
Audio 6 Input Mixer Amplifier Circuit Diagrams The mixer circuit above has 3 line inputs and 3 mic inputs. The mic inputs are suitable for low impedance 200-1000R dynamic microphones. An ECM or condenser mic can also be used, but must have bias applied via a series resistor. As with any mixer circuit, a slight [...]
Producing low-distortion sine waves, this oscillator operates over the range 16 to 22000 Hz. The circuit is based on two articles that have appeared earlier in Wireless World – Roger Rosens’ “Phase -Shifting Oscillator”, February 1982 pp. 38-41, and J. L. Linsley Hood’s “Wien-Bridge Oscillator with low harmonic distortion” from May 1981 pp. 51-53. This [...]
