The transition from analog audio to digital formats such as CD, MP3, and later high-resolution digital audio files revolutionized the recording industry. Digital audio provides higher fidelity, wider dynamic range and greater flexibility, and the ever-growing audio field cannot do without high-quality PCB manufacturing and assembly to realize complex functions.
Mixers and Audio Interfaces: Mixer functions such as input and output stages, tone controls, and effects. The various functions of the audio interface, including analog-to-digital and digital-to-analog conversion, input and output stages, and buffer amplifiers, also rely on PCBs to implement functions.
Amplifier: Amplifiers and headphone amplifiers both use PCBs to route power and audio signals, including input and output stages, power supply, and tone controls.
Speakers: Connecting different components such as tweeters, woofers, and crossover networks, the PCB is used to control and adjust various functions of the speakers, including crossover networks, amplifiers, and protection circuits.
Microphones: Both condenser and dynamic microphones require various components to be connected and mounted to control and adjust various functions of the microphone, including preamplifiers, filters, and output stages.
Headphones: The headphone driver needs to be connected to the cable and controls, using the PCB to control and adjust the various functions of the headphones, including the driver circuit, amplifier and controls.
Effects processors: Devices such as reverb units, compressors, and equalizers require high-quality PCBs to connect audio signal paths, controls, and power supplies.
Synthesizers: Analog and digital synthesizers for interfacing oscillators, filters, envelopes, and other components.
Recording equipment: tape decks, SSD recorders, analog tape decks, etc.
Digital Audio Workstation (DAW): Controlling and adjusting the various functions of a DAW, including input and output stages, digital signal processing, and data transmission are all inseparable from high-quality PCB fabrication.
