Internet Radio and Music Streaming Services
Accessing the internet via Ethernet and your home network, the T-4070 brings streaming audio and internet radio to your listening space. Enjoy a virtually limitless choice of internet radio channels from services such as vTuner, build your own playlists, or find artists similar to your favorites quickly and easily. No more waiting for downloads or filling up valuable disc space on smart phones.

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.

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.

Onkyo Remote Apps for iPod touch/iPhone and Android
The Onkyo Remote 2 for iPod touch/iPhone*1 and the Onkyo Remote for Android*2 applications both provide an intuitive way to control network-capable Onkyo hi-fi systems. Users can even control other Remote Interactive-equipped components—such as integrated amplifiers and CD players—using either application via the T-4070, turning your handset into a convenient all-in-one remote controller*3. At your fingertips, you have the ability to perform a wide range of adjustments, including selecting an input source; stopping, skipping, or pausing tracks; or altering bass and treble settings. Both applications are available as free downloads.
*1 Compatible with iPod touch (3rd generation or later) and iPhone 3GS or later. (All models require iOS 4.2 or later.) *2 Requires Android OS 2.1 or later. *3 Compatible Onkyo hi-fi components comprise A-9000R and A-9070 amplifiers, C-7070 and C-7030 CD players, and all earlier-model Onkyo CD players with RI capability.

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.
