Onkyo today three new entry-level home theater receivers to its line-up which include networking capabilities and a 'Made for iPod/iPhone' USB interface. Previously, these features were only available in premium priced Onkyo models.

The new devices include the 7.2-channel TX-NR609, the 5.1-channel TX-NR509 and the 5.1-channel TX-SR309. The models designated 'TX-NR' are network-capable and all three have front-panel USB connections.

The two network-capable receivers support streaming PC audio and Internet radio, and provide compatibility with Windows 7 and DLNA. The Internet connection can also be used to update the receiver’s firmware. The networking models can also be controlled by Onkyo’s free Apple iOS Remote App. This front-panel USB port also offers a digital connection for an iPod or iPhone, along with support for audio playback from USB mass-storage devices.

Other features shared by these models include PLL jitter-cleaning circuitry to preserve signal clarity; lossless Dolby TrueHD and DTS-HD Master Audio decoding; an overlaid on-screen display for adjustment of settings; and a new front panel design.

Features of the more expensive TX-NR609 A/V Receiver include: THX Select2 Plus-certification; Marvell Qdeo video upscaling technology; Audyssey DSX audio processing; six HDMI inputs; a powered second zone which lets you play a different audio source in a second room equipped with stereo speakers.

The Onkyo TX-NR609 will be available in early April for $599 while the TX-NR509 and TX-SR309 will sell for $299 and $399 respectively.
