The MS6712 is a digital control audio processor designed for low voltage operation, featuring 4 stereo inputs and 4-channel outputs. It integrates volume control, tone adjustment (including bass and treble), balance control (left/right), and fader control (front/rear) within a single chip. Additionally, the MS6712 includes a loudness function and selectable input gain, allowing for easy construction of a high-fidelity audio system. All functions are programmable via the serial I2C bus. Upon power-up, the default settings of the chip are: volume at -78.75 dB, stereo channel 4 selected, all speakers muted, and gains for the input stage, bass, and treble set at 0 dB. Manufactured by MOSA Electronics Corp.

The MS6712 audio processor is a versatile component suitable for various audio applications, especially in consumer electronics where space and power efficiency are critical. Its architecture allows for seamless integration into audio systems, providing robust control over sound characteristics.

The processor's four stereo inputs enable the connection of multiple audio sources, while the four-channel outputs facilitate the distribution of audio signals to various speakers or amplifiers. The volume control allows for precise adjustment of audio levels, essential for user comfort and system performance.

Tone control features, including bass and treble adjustments, enable users to tailor the audio output to their preferences or the acoustic characteristics of the environment. The balance control ensures that sound can be directed appropriately between left and right channels, enhancing the stereo experience. The fader control further allows users to manage the sound distribution between front and rear channels, making it particularly useful in multi-speaker configurations.

The inclusion of a loudness function compensates for the perceived loss of bass at lower volumes, ensuring a richer listening experience across all volume levels. Selectable input gain provides flexibility in accommodating various audio source levels, preventing distortion or inadequate sound output.

Programmability via the I2C bus simplifies integration into digital systems, allowing for easy adjustments and control through microcontrollers or digital signal processors. This feature enhances the MS6712's adaptability in modern audio applications, where digital control is increasingly prevalent.

The default states upon power-up ensure that the system starts in a safe configuration, preventing unexpected loud outputs or speaker damage. The ability to mute all speakers initially provides an additional layer of safety for users when powering on the audio system.

In summary, the MS6712 is a compact and efficient audio processor that combines essential audio control features into a single integrated circuit, making it an ideal choice for high-fidelity audio applications in low-voltage environments. Its programmability and default settings further enhance its usability in diverse audio system designs.The MS6712 is a 4 stereo inputs/4-channel outputs digital control Audio Processor for the low voltage operation. Volume, Tone (bass and treble), balance (left/right), and fader (front/rear) processor are incorporated into a single chip.

The MS6712 also has the loudness function and selectable input gain. These functions CAN be built a Hi-Fi Audio 2 system easily. All functions are programmable via the serial I C bus. The default states of the chip as the power is on are: the volume is -78. 75dB, the stereo 4 is selected, all the speakers are mute and the gains of the input stage, the bass and the treble are 0dB.
