The TX-NR807 and non-networking TX-SR707, also introduced today, are Onkyo's first receivers to offer AudysseyDSX soundstage extension processing in addition to Dolby Pro Logic IIz height-capabilities.
Notably, the line features the introduction of several industry-leading performance features, including the world's first AudysseyDSX with front height or expanded width channels in the receiver category (AVR-4310CI) and Dolby Pro Logic IIz decoding in all models.
The Onkyo TX-NR807 is one of the first receivers to incorporate AudysseyDSX technology, which allows the back surround channels to be retasked for front-wide speakers to expand the width of the sounds stage, or for front height speakers to provide vertical ambience effects.
