premium digital surround a/v receivers the performance alternative in home entertainment the premium digital concept defined without a fundamental approach to audio amplification design the pursuit of superior home theater reproduction is next to impossible also ensuring that audio signals are delivered without interference is an absolute necessity onkyo has developed its own technologies to provide the backbone of our a/v receiver line-up it s only then that we add selected functions that will create the bone-rattling bass otherworldly atmosphere and scintillating soundtracks that can transform your home entertainment experience into something truly remarkable vector linear shaping circuitry vlsctm 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 pulsenoise-free audio signal that faithfully reproduces the acoustic detail and subtle nuances of all your audio sources and breathes life into digital media wide range amplifier technology wrat amplification power through design 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 large signal gains e.g explosions and 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 to achieve a frequency response out to 100 khz for highdefinition 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 cinema-standard movie soundtracks with dynamics and clarity optimum gain volume circuitry in conventional volume-attenuation methods the signal comes close to the noise floor at low volumes and is therefore susceptible to interference even if the amount of noise is minimal it taints the signal as it is amplified onkyo s optimum gain volume circuitry adjusts the gain so that less than half the typical amount of attenuation is necessary the signal never comes close to the noise floor thereby eliminating the possibility of the noise contamination that plagues conventional volume-attenuation designs non-scaling configuration if you already own a dolby® digitalcompatible receiver you can choose to send the low frequency effects lfe signal to the front left and right speakers instead of to the subwoofer naturally this option is beneficial for those who don t have a subwoofer but it s also suitable for those who own high-quality speakers that can reproduce the lfe as effectively as a subwoofer itself many of our rivals receivers add the 24-bit lfe to front speakers before digital-to-analog conversion this results in loss of audio information onkyo s non-scaled circuit design adds the lfe to the front channels after converting all the signals to analog by incorporating a more complex circuit design every single bit of audio data is faithfully preserved 4 home theater components
