Basic Tone Control

The following diagram illustrates the schematic of an Active Tone Control circuit, commonly referred to as "ACTOR." The ACTOR is an electronic audio circuit designed to enhance loudness by adjusting bass and treble audio signals. It operates using the Baxandall system. Additionally, this diagram represents a 12V stereo tone control circuit, which is also available as a kit at local electronic part stores. The circuit is based on a standard tone control configuration, utilizing two FCS9014 transistors for each channel, resulting in a total of four transistors for the 12V setup. This stereo audio tone control circuit is built around the LM1036 integrated circuit. It allows for control over bass and treble levels, volume, and balancing between the right and left channels (inputs 1 and 2). This circuit is suitable for various stereo applications, including car radios, televisions, audio systems, MP3 players, and DVD players. It is an economical high-fidelity (hi-fi) tone control circuit. The schematic provided represents a mono tone control; constructing a similar circuit will yield a stereo configuration. For optimal sound quality, it is recommended to use high-quality components such as metal film resistors, MKM capacitors, tantalum capacitors, and quality cabling, along with a stabilized power supply. The quality of components and cabling significantly impacts the performance. The circuit also includes a tone booster feature, which enhances the sound signal for improved power in both low and high frequencies. The transistors used in this circuit are Q1 - ZTX384 and Q2 - BC415P. The circuit's peak frequency is set at 5000 Hz, providing a cleaner and more penetrating sound. Additionally, the schematic diagram for the Axe Grinder Electric Guitar Effect is available for download in PDF format at the end of the post. The Axe Grinder is designed with several key features, offering a wide range of distortion sounds and an effective clipping section of the effect.

The Active Tone Control (ACTOR) circuit is a versatile audio enhancement tool that employs a Baxandall tone control topology. This configuration enables users to fine-tune the audio output by adjusting the bass and treble frequencies, thereby improving the overall listening experience. The 12V stereo tone control circuit, which can be assembled from a kit, utilizes two FCS9014 transistors per channel, ensuring that audio signals are amplified effectively while maintaining fidelity.

The LM1036 integrated circuit serves as the core of the tone control functionality, allowing for precise adjustments to the audio signals. The circuit design includes provisions for controlling the volume and balancing the audio output between the left and right channels. This is particularly beneficial for stereo applications, as it ensures that the audio experience is consistent across both channels.

For optimal performance, the circuit should be constructed using high-quality components. Metal film resistors provide better accuracy and lower noise compared to standard carbon resistors, while MKM and tantalum capacitors contribute to improved signal integrity and stability. Additionally, using quality cabling can minimize interference and signal loss, further enhancing the sound quality.

The tone booster feature integrated into the circuit is designed to amplify the audio signal, making it more powerful across both low and high frequency ranges. This is particularly useful for applications where enhanced audio output is desired, such as in live performances or high-energy music playback.

The specified transistors, ZTX384 and BC415P, are selected for their suitable characteristics in audio applications, providing reliable performance and good frequency response. The design's peak frequency of 5000 Hz is strategically chosen to ensure clarity and presence in the audio output, making it ideal for a variety of musical genres and listening environments.

In summary, the ACTOR Active Tone Control circuit is a well-engineered solution for enhancing audio quality in various applications, combining ease of assembly with high-fidelity performance. The schematic diagrams provided serve as a valuable resource for both novice and experienced builders looking to implement effective tone control in their audio systems.The following diagram is the schematic diagram of Active Tone Control circuit, or we often call thic circuit as "ACTOR" Active Tone Control or ACTOR is a electronic audio circuit that serves to increase the Loudness (Bass and Treble audio signal) is active because it uses the Baxandall system. This circuit does not use a. The following diagram is the circuit diagram of 12V stereo tone control which also available in kit, you may find the kit at electronic part store around your place. The circuit build based on ordinary tone control circuit, using 2 transistors FCS9014 in each channel, so there are will be 4 transistors in this 12v.

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, .

This is a cheap high fidelity (hi-fi) tone control circuit. The schematic is one channel (mono) tone control, build the similar circuit will make it become stereo. Use good component (such as metalfilm resistors, MKM capacitors, tantalum capacitors, good cable quality) and stabilized power supply for better sound quality output.
