  • A Digital to Analog Converter, also known as a DAC, is a device that converts a digital code to an analog signal. Most modern audio signals are stored in digital form (for example MP3s and CDs) and in order to be heard through speakers they must be converted into an analog signal. Most digital music players, such as a Smartphone or iPod, and PC sound cards come with internal DACs, although, they are very basic and do not deliver music in high resolution. Firestone Audio delivers a high quality DAC system with internal amplifier that allows you to play your music in high definition at the volume level that you desire. This system is the ideal peripheral for the music lover that stores their music library on their PC.

    An Analog to Digital Converter, also known as an ADC, is a device that converts the input continuous quantity to a digital number that represents the quantity's amplittude. Instead of doing a single conversion, an ADC often performs the conversions periodically. The result is a sequence of digital values that have converted a continuous-time and continuous-amplitude analog signal to a discrete-time and discrete-amplitude digital signal.
