Intermodulation Distortion

Intermodulation Distortion

0.004% @ 1kHz

A complex form of distortion occurring when two signals at different frequencies are produced at the same time, creating additional signals at various other frequencies and at various amplitudes.

Signal to Noise Ratio

>105dB

The ratio of desired signal to noise signals present in the output. This figure is referenced to the rated output of the CD player, taking into full account all potentially annoying hum components.

Dynamic Range

>100dB

The difference between the loudest and quietest portions of a signal. Due to the increased dynamic range offered by HDCD encoding, this specification must be greater than the 96dB limit inherent in the standard 16-bit CD format.

Channel Separation

>110dB @ 1kHz

Refers to the immunity of a signal from one channel leaking to the other channel. The higher the value, the better the isolation of the two channels.

Channel Balance

±0.5dB

The maximum difference in the output level of one channel compared to the output level of the other channel.

Phase Linearity

±0.5°

This shows the difference in phase of the input to the D/A converter compared with the analog output.
