Onkyo has added three home theater receivers (TX-SR607, TX-SR507, TX-SR307) to its lineup, including the “world’s first” with Dolby ProLogic IIz processing.

The TX-SR607, a 7.2-channel receiver with Dolby Pro-Logic IIz, adds a vertical aspect to the sound with left and right channel front height speakers above the main speakers.

Each model supports Blu-ray and other HD A/V source components, 1080p resolution, Deep Color, and x.v.Color.

They also feature:

• Audyssey 2EQ calibration to correct frequency and time domain in each channel’s output
• Audyssey Dynamic Volume technology to optimize the dynamic range at any listening level
• Audyssey Dynamic EQ to fix problems with reduced sound quality at low listening levels

Onkyo also included four gaming modes: Rock, Sports, Action, or Role Playing to match the listener’s experience to the gaming content.

The TX-SR607 and TX-SR507 have HDMI repeaters and Dolby True HD and DTS-HD Master Audio. Both also offer new proprietary rear-panel universal port to simplify connection to the HD Radio Tuner and iPod Dock that will be available in late spring.

The TX-SR607 also has dual subwoofer line-outputs and upconverts analog sources to HDMI via Faroujda DCDi technology.

The entry-level TX-SR307 has HDMI pass-through switching on three inputs.

The 5.1-channel TX-SR307 and 5.1-channel TX-SR507 have 65- and 80-watts per channel, respectively. The TX-SR607 is rated at 90 watts per channel.

MSRP:
TX-SR307 — $299 (March)
TX-SR507 — $399 (March)
TX-ST607 — $599 (April)
