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.
 
DLNA-Certified Home Network Capability
The T-4070’s DLNA 1.5-certified home network capability lets you share your music seamlessly between devices. You can send a range of audio files stored on your home PC or media server to the T-4070, even if it’s set up in another room. Supported file types include MP3, WMA, WMA Lossless, FLAC, WAV, Ogg Vorbis, and AAC.
 
Direct Digital Connection of iPod/iPhone and Flash Memory via USB Port
The T-4070’s front-panel USB port lets you access MP3, WMA, FLAC, and AAC audio files stored on a USB flash drive or iPod/iPhone. As the audio signals are transported in digital form, rather than analog, there is much less chance for signal degradation. End result: your music sounds cleaner and more faithful to the original. A further benefit of the USB input is that it lets you use the system’s remote controller to play back audio files on the connected device.
 
Separate 192 kHz/24-Bit DACs for L/R Channels
High-quality Wolfson® DACs work to optimize analog audio performance on the T-4070. The tuner features dual 24-bit WM8742 DACs, which support sampling rates of up to 192 kHz. Although these DACs are specified to handle two-channel audio on a single chip, Onkyo employs separate chips for each stereo channel to ensure the most accurate digital-to-analog conversion.
 
Fully Flat Anti-Vibration Chassis
When it comes to parts and construction, it’s not in Onkyo’s nature to cut any corners. The T-4070 is no exception. Build quality starts from the ground up with a highly rigid, 1.6 mm-thick, fully flat chassis that provides excellent protection against shelf-borne vibrations.
