With Dolby Pro Logic II for a New Way To Enjoy Home Theater

The AVR-683 A/V receiver with Dolby Pro Logic II and powerful output of 110 watts per channel lets you enjoy multi-channel home theater entertainment in a new dimension. In addition to Dolby Digital and DTS, you can now also enjoy existing Dolby Surround programs and conventional stereo sources such as CD in convincing 5.1-channel likeness. And if you have only two speakers, one for each stereo channel, you can use the AVR-683's Virtual Surround mode to give yourself the sensation of being completely surrounded by sound as you would in a real theater.

■Fully Discrete, Equal Power Five Amplifier Channels, 110 Watts Each

Front	110 W + 110 W (6 ohms, 1 kHz, 0.7 % THD)
Center	110 W	(6 ohms, 1 kHz, 0.7 % THD)
Surround	110 W + 110 W (6 ohms, 1 kHz, 0.7 % THD)

For optimum Dolby Digital and DTS reproduction, the AVR-683 features high quality, wideband audio amplification, providing 110 watts power output for each of the five main channels. A large capacity power supply includes a high current power transformer along with discrete power output devices on all five amplifier channels for highest dynamic range and superb reproduction clarity.

■Dolby Pro Logic II Decoder

Enjoy 2-channel stereo recordings in stunning 5.1-channel surround playback.

The Dolby Pro Logic II decoder reproduces dynamic 5.1-channel surround sound not only from normal 5.1-channel DVD but from 2-channel sources such as videos and CDs, too. Dolby Pro Logic II uses matrix decoding technology that has been dramatically improved over Pro Logic.

■Dolby Digital and DTS Decoders

Equipped with both Dolby Digital and DTS 5.1 channel decoding, the AVR-683 provides thrilling surround sound with the thousands of Dolby Digital and DTS encoded DVDs, as well as the growing library of DTS 5.1 channel music recordings available on CD.

■High-quality DSP

A high-quality 32-bit DSP “MELODY32” from Analog Devices has been used in the DSP processor, placing the AVR-683 at a higher rank than other models of this class in its ability to accurately decode and reproduce the superior quality of Dolby Pro Logic II.

■Cinema Equalizer

The sound from movie sources recorded in Dolby Digital, DTS or other formats emphasizes high-frequency range due to a theater’s front speakers being placed behind the movie screen. If this sound is reproduced in the home theater without correction, the high-frequency range is too strong. The AVR-683 features a Cinema Equalizer to correct these high-frequency components so that the sound is clearer and easier to listen to.
