Experience Onkyo Emotion
Emotion: Something that used to only be a reaction to what’s on the screen or floating through the air in dialogue or music. Onkyo emotion:
A reaction before you’ve even attached the first cable of the TX-NR901. Relief comes from knowing this receiver gives you exclusive sound
quality, performance features and high grade parts such as 192 kHz/24-bit DACs, dual 32-bit DSP chips, composite and S-
-Video to component
video upconversion and our exclusive VL technology for a smooth digital signal. The convergence of home theater and home network manifests
itself in Onkyo’s Net-Tune protocol which makes the TX-NR901 part of the only line of A/V receivers to boast of this ability. Most importantly,
you have peace of mind knowing you have chosen a receiver ready to handle the technology and ever increasing demands of the movies and
music of today—and tomorrow.
TX-NR901
THX SELECT 7.1-CHANNEL A/V SURROUND HOME NETWORK RECEIVER
THX Select Certified
The TX-NR901 boasts the distinction of the exclusive THX Select badge of
approval. This gives you assurance that this receiver passed (and often exceeds)
THX’s numerous requirements in such areas as frequency response, distortion,
power output, and stability.
Dolby Digital EX
Dolby Digital EX creates six full-bandwidth output channels from 5.1-channel
sources. This is done using a matrix decoder that derives three surround channels
from the two in the original recording. For best results, Dolby Digital EX should
be used with movie soundtracks recorded with Dolby Digital Surround EX.
DTS 96/24
This format offers you the sound quality of the original 96-kHz, 24-bit master in
5.1-channel surround sound for music and movie soundtracks on DVDs encoded
in DTS 96/24. Also, you won’t have to worry about buying a new DVD player.
DTS 96/24 can be carried on DVD-Video, or in the video zone of DVD-Audio. This
gives you the convenience of making it playable on all DVD players.
Color-Coded Inputs and Outputs
Onkyo’s commitment to bringing the most user-friendly designed products to
market further manifests itself with color-coded inputs and outputs. Now you’ll
no longer have worries about which wire goes to which input or output. Simply
attach the color-coded label to the appropriate wire, attach the cable to the same
colored input or output for fast and easy connection.
VLSC (Vector Linear Shaping Circuitry)
Conventional D/A conversion methods reduce digital pulse noise at the conversion
stage but can’t remove it completely. Previously only available on Onkyo’s
high-end components, VLSC (Vector Linear Shaping Circuitry)employs a unique
D/A conversion circuit to overcome this problem. Data is converted between the
sampling points and these discrete sampling points are joined with analog vectors
in real-time to produce a smooth output wave form. The result—a noiseless,
smooth analog signal based on the digital source.
Crossover Adjustment for Bass Management
Previously crossover frequency was fixed at 80 Hz. With Crossover Adjustment,
you can set the frequency at 40/60/80/100/120 or 150 Hz depending on your
speaker’s bass playback ability. This lets you more accurately match the
performance characteristics of the subwoofer to your front speakers.
Component Video Upconversion
Convenience is upgraded with the ability to run just one cable from your receiver
to your HDTV with composite/S-Video to component video upconversion. Hook
up your video player, CD player, LD player—all your S-Video or composite video
out components—to the back of the TX-NR901 and each signal will flow to your
compatible TV or projector via one component video cable.
Net-Tune
Unprecedented access to radio stations around the world is made possible by
Onkyo’s exclusive Net-Tune protocol. Hook up your TX-NR901 to a router or hub
connected to your broadband modem via a high-speed Ethernet cable. Press the
Net-Tune button on the front panel and you’re ready to surf the airwaves of
cyberspace. You can also add new life to the existing content on your computer
by hooking it up to the TX-NR901 via a standard network hub. You’ll agree, your
MP3s, WAV, WMA files and Internet radio have never sounded so good.
