Category: Audio Circuits / Tone Balance Views: 2789 Rank: 0 Based on the classic Baxendall tone control circuit, this provides a maximum cut and boost of around 10dB at 10KHz and 50Hz. As the controls are passive, the first transistor, Q1, is configured as common-collector to act as a buffer stage. The last transistor, Q2, provides a slight boost.Note that the gain of the output of the Baxendall circuit is less than one because of passive nature of it. The output is designed to feed an amplifier with input impedance of 10kohms to 250kohms. visit page.

Related circuits Three band active tone control provides bass, midrange, and treble boost and cut. With components shown, the cutoff points for bass, midrange, and treble are 200Hz,1kHz,,7kHz, repsectively. Here a simple design for an attractive tone. They operate on a passive principle, ie without amplification. The circuit only weakened and therefore require no power. As can be seen, the circuit is built with two T-filters in the same way as the active bass / treble tone control. Only is the... ELECTRIC FIELD DISTURBANCE MONITOR This schematic is the power supply and front-end sections of the field monitor that is discussed in more detail at Electric Field Disturbance Monitor. (this link is off-site) The system can detect human and animal motion by the electric fields they disturb. Bass-treble, Volume, balance and Loudness control 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... Equal-element filter improves passband performance Designers originally conceived equal-element filters as all-pole microwave bandpass filters that provide minimum center-frequency insertion losses for specific values of resonator-unloaded Q (Reference 1). All resonators of the equal-element bandpass filter operate at the same loaded Q. For LC... Parametric And Sub-Woofer Equaliser Parametric equalisers are normally quite complex, and allow for variable Q (Quality factor), so the peak or dip can be made sharp or broad. This unit does not allow this, but the Q will vary as the amount of equalisation is varied. Perhaps surprisingly (or perhaps not), this works well in... Digital Volume Control with DS1669 This digital volume control has no pot to wear out and introduces almost no noise in the circuit. Instead, the volume is controlled by pressing UP and DOWN buttons. This simple circuit would be a great touch to any home audio project. Based on the classic Baxendall tone control circuit, this provides a maximum cut and boost of around 10dB at 10KHz and 50Hz. As the controls are passive, the first transistor, Q1, is configured as common-collector to act as a buffer stage. The last transistor, Q2, provides a slight boost.

i've already tested a transistorized control circuit,and i improvised it.one alternative is to tapped an inductor.we call it the an input captain transformer,i already tested it using a transistorized tone control circuit.one example is to tapped one terminal to the emitter, of the npn driver transistor,specially common emitter drive configuration. and the other terminal of the input captain transformer to the ground.also parallel your input captain's two terminal with a capacitor rated at .01-.1uf/50v mylar or any non polar capacitor, to compensate the high frequency response of the tone control.the effect of this so called input captain transformer is an extremely low frequency response to your tone controller.a rubberlike bass effect to your woofer.available in cebu city philippines.

for best results using an input captain transformer, put switch in series with it.
