Onkyo’s amplification philosophy focuses on capturing the energy and dynamism contained in the audio signal and reproducing it without loss.

Why is Dynamic Audio Amplification Important?

Audio signals are not static like a test tone, but rather a countless collection of constantly moving waves. While static measurements such as S/N ratio and Total Harmonic Distortion are important, Onkyo believes that excellent dynamic and transient response is the key to emotionally involving sound. Dynamism—the “life” in music—is achieved when the amp can respond to changes in the signal instantaneously, so notes start and stop naturally and the nuances in attack, decay, sustain, and release are voiced with conviction.

Hi-Current Amp Design

Onkyo home theater receivers represent the culmination of almost 70 years’ experience in amplifier design. The unique elements of our amplification system comprise high-current, low-impedance architecture to accurately control large speaker cones while enabling instantaneous response to dynamic changes, and discrete wide-range amplifier circuit topology to eliminate phase shift for clear and accurate audio imaging.

Non-Phase-Shift Amp for Realistic Audio Imaging

Onkyo’s Wide Range Amp Technology (WRAT) circuit layout prevents phase shifting by pushing the roll-off point higher than the listening-level frequency. Amplifying sound without phase shift creates an uncommonly well-focused and realistic audio image.

Noiseless Audio Processing with VLSC™

Onkyo’s Vector Linear Shaping Circuitry (VLSC) reassembles the signal in its original form following digital-to-analog conversion. Unlike conventional filters, VLSC completely removes electrical pulse-noise generated during this process, allowing the soundwave to be amplified with exceptional fidelity.
