ADOT

ADOT or Audiophile Digital Optical Technology, is a company that specialises in optical fibre upgrade kits. The kits are designed to offer better quality distribution when streaming over a network. ADOT have a close connection with Melco, who make high end music libraries that distribute files over a network.

ADOT’s technology is used to optimise the sound quality of audio over a network, It bypasses the unshielded noisy nature of Ethernet, by using a fibre-optic network. ADOT kits convert the audio signal to light and back again. As a result the signal is immune to interference.

The ADOT project was developed by Melco’s UK based distributor ADMM. A team was formed of Melco users as well as industry experts. The aim was to improve on the noisy nature of Ethernet networks, for audio distribution. The team knew that the best way was to totally isolate the audio signal by using optical fibre.

Digital audio can be as delicate as analogue audio. Noise can cause rounding of the waveform edges causing dropouts, timing errors and jitter. The signal needs to be treated with respect, especially with today's hi-res audio, which has a high data rate. Copper networks were not designed to carry audio and are not shielded. Moreover, long cable runs act as aerials, picking up all kinds of noise. Hence the need for an optical signal path.
