6 Home Theater Components
Onkyo's H.C.P.S. (High Current Power Supply) concept is based around power transformers with the capability to
respond to the wide dynamics of home theater. In the case of the TX-NR906, a massive toroidal transformer
improves power efficiency and radiates very little noise into the surrounding circuitry, while two separate
transformers cater specifically to audio and video processing.You'll also find
capacitors (operating at up to
18,000 microfarads) that store the
charge necessary to support an
effective power supply.
Taking a cue from the world of high-end audio, you'll find bi-
amping and bridging capabilities in Onkyo's 2008 line-up.This
allows for a number of different home theater set-ups beyond
the standard surround-sound configurations. Compatible front
speakers can be bi-amped for separate tweeter and woofer
inputs. Also, bridging enables you to double the power output
to compatible front speakers.
In conventional digital-to-analog methods, it is impossible to completely remove noise,
which taints the analog signal and ultimately degrades the sound emitted from your
speakers. With Onkyo's VLSC, data is continuously sampled between two
discrete points (via a signal comparison generator), and the difference is joined
with analog vectors in real-time to produce a smooth output wave form.The
VLSC digital-to-analog conversion method results in a smooth, virtually pulse
noise-free audio signal that faithfully reproduces the acoustic detail and subtle
nuances of all your audio sources, and breathes life into digital media.
Uncommonly Low Negative-Feedback Design—Get cleaner sounds on program peaks
Negative feedback (NFB) is the most cost-effective way to reduce noise at lower frequencies, but it will severely
inhibit an amplifier's ability to respond to musical crescendos and to produce sound at high frequencies. We use a
low negative-feedback design with audiophile-grade, close-tolerance components at critical points in the signal path.
This design achieves a frequency response out to 100 kHz for high-definition and regular DVD formats, high-
resolution DVD-Audio and Super Audio CD,
regular CDs, digital music files, and the latest
gaming software.
Closed Ground-Loop Circuits—Enjoy distortion-free audio at any volume
If an amplifier's ground potential (voltage) fluctuates during playback, you can expect noise. In an open-loop circuit
design, where all circuits are connected to the power supply via one loop (like on many amplifiers), the noise
multiplies exponentially. Onkyo's sophisticated
closed-circuit design enables each circuit to go
and return directly to the power supply, which
cancels any individual circuit noise and keeps
the ground potential free of distortion.
High Instantaneous-Current Capability—Experience home entertainment with greater impact
After an amplifier outputs an audio signal, the speakers accumulate energy, reflex, and send energy back to the
amplifier.The amplifier must immediately cancel the speakers' reflex energy and instantaneously send out the next
signal. A high current is necessary to handle speaker impedance fluctuations, which can force an amplifier to provide
four to six times its usual current load.The instantaneous current capability
of even Onkyo's least expensive WRAT receivers exceeds that of most
conventional units, which commonly have less than half the current
capability. An Onkyo receiver will deliver movie soundtracks with cinema-
standard dynamics and clarity.
