Onkyo Receivers Boast 9 Amp Channels By Mark Fleischmann August 31, 2009 — Normally we don't use the News column for new product releases. But when there's a first, we jump on it, and we're jumping on three new receivers from Onkyo that deliver nine amplifier channels. They also support dual subwoofer outputs, making them 9.2-channel models.

Why this, why now? The advent of Audyssey's DSX and Dolby's Pro Logic IIz post-processing modes have prompted the increase. Both of these modes add height while DSX also offers the option of width. With nine amp channels, you can run any two of the following: height, width, and back-surround.

The receivers are the TX-NR5007 ($2699, shown), TX-NR3007 ($2099), and TX-NR1007 ($1599). These THX Ultra2 Plus also boast THX Volume Plus, a low-volume listening mode that evens out differences among source inputs and tames the insane dynamics of some movie soundtracks. Also included in the two top models is Dolby Volume, which does the same.

An ethernet connection allows streaming with Pandora, Rhapsody, and vTuner, not to mention Sirius. Video processing is HQV Reon-VX. ISF Certified Calibration Controls (ISFCCC) allows a qualified installer to tweak everything to perfection.
