Powered Zone 2 allows your rear surround amplifier channels to power stereo speakers in a second room while 5.1-channel sound in happening in the main zone. With Audyssey 2EQ, the receiver sends test signals to your speakers. An included calibration microphone accepts the signals, which the receiver uses to adjust channel levels and time delay settings for each speaker.
Each receiver also features three HDMI inputs, Audyssey 2EQ automatic room correction, and Onkyo’s own Music Optimizer software, which boasts improved MP3 and AAC performance.
Both receivers will be available next month. The TX-SR576 will run $479, with the TX-SR506 coming in at $379.
