Basic Tone Control

Fri, 12 Nov 2010 06:05:41 +0000

This is a very basic circuit diagram of 3 band tone control. This basic tone control circuit was originally intended for home audio use, but should be able to be hacked into an effect circuit with very minor modification.

Resistance value of resistor R1 is left up to the user depending on gain needs, R2 is unknown – for? experiment purpose. The op-amps are not critical, any standard ones could be used (eq: 741, LM324, etc).

Power supply used for this circuit depends the op-amp IC used. Use the IC datasheet to know the recommended voltage. Some op-amp IC needs symmetrical power supply to work, just find the op-amp which require general power supply (asymmetrical). A regulated power supply will be better for this circuit.

For better sound performance, use high quality component such MKM capacitor (non polar), tantalum capacitor (bipolar), metalfilm resistor, etc.

Hi-Fi Tone Control

Wed, 22 Sep 2010 22:42:39 +0000

This is a inexpensive high fidelity (hi-fi) tone control circuit designed just with two low cost transistors as the active components. The schematic is one channel (mono) tone control, build the similar circuit will make it become stereo channel.

This Hi-Fi tone control circuit can be operated with wide range supply voltage, 12V – 24V DC. Three potensiometers used for sound adjustment: volume level, bass and treble level.

Use good components (such as metalfilm resistors, MKM capacitors, tantalum capacitors, good cable quality) and stabilized/regulated power supply for better sound quality output, of course it will be need more cost.

The quality of components, cabling and power supply will affect the quality of the output.

Stereo Tone Control with LM1036

Sun, 04 Oct 2009 03:21:42 +0000

This is a stereo audio tone control circuit which build based on IC? LM1036. This circuit will controll bass/treble level tone, volume and balance between right channel and left channel (input 1 and 2 ). You may use this circuit for stereo applications such as car radio, TV and audio systems, mp3 player, dvd player, ipod and more. An additional control input allows loudness compensation to be simply effected. The circuit should be works with supply voltage 9V to 15V DC.

Tone control features:

Wide supply voltage range, 9V to 16V

Large volume control range, 75 dB typical

Tone control, ?15 dB typical

Channel separation, 75 dB typical

Low distortion, 0.06% typical for an input level of 0.3 Vrms

High signal to noise, 80 dB typical for an input level of 0.3 Vrms
