Wireless Streaming with AirPlay

AirPlay allows you to stream audio from your iOS device or iTunes-equipped personal computer to the T-4070 over your household Wi-Fi network. The protocol transmits audio files with no deterioration in original sound quality, making it ideal for sensitive hi-fi systems.

Using AirPlay

DIDRC (Dynamic Intermodulation Distortion Reduction Circuitry)

Onkyo has developed DIDRC technology for use in its hi-fi components. Despite being beyond the normal range of human hearing, frequencies above 100 kHz are susceptible to forms of distortion from digital devices. Subtle distortion in the super high frequency range can generate “beat interference”, which can affect the original sound characteristics. DIDRC effectively reduces perceptible noise and delivers clearer-than-ever audio.
