1.57160001-K DSDO110 digital output (digital out), the transmission is a digital audio signal, is used for external transmission between the turntable and the decoder, the transmission mode is generally coaxial (RCA or BNC interface), optical fiber (square port or 3.5mm round port), In the high-end segment, there is AT&T(ST Glass fiber). There is also a balanced digital output (AES/EBU), which is similar to coaxial but uses a balanced transmission mode suitable for long distances, and the interface is an XLR three-core Canon head. It should be noted that USB or Firewire is not a digital output, nor does it transmit a digital audio signal.
2.57160001-K DSDO110 analog output (analog out), which transmits analog audio signals, is used for external transmission between the decoder and the amplifier, and the interface is generally RCA(one per channel) or 3.5mm(simplified interface for portable devices, common ground). There is also a balanced analog output, using a balanced mode of transmission, the interface is XLR three-core Canon head (one for each channel).
3.57160001-K DSDO110 A complete digital audio player audio source (any device that can play digital audio files and has analog output, such as a CD player, sound card, or even an ipod), must have a built-in decoder (digital/analog converter). Any audio source with a digital output must have a turntable (transport) built in. Here the turntable has two parts, for the CD machine, the turntable because the need to read the disk, so must contain a stable reading disk mechanical structure, coupled with a digital audio signal transmission circuit, both have an impact on the quality of the digital output. The sound source such as the sound card does not require the mechanical structure of the reading disc, so only a digital audio signal transmission circuit affects the output quality (the computer that captures the digital audio file, including the optical drive, power supply, system, software Settings, etc., as a whole, acts as the mechanical structure of the reading disc).
