The technologies work to reduce noise across the frequency range, guaranteeing a clear, balanced, and natural sound. It achieves this by employing a low negative feedback amplifier design, preserving the essential energy and life contained within the recording; using closed ground-loops to cancel unwanted noise from individual circuits; and by enabling high current flows to cancel reflex energy from the speakers. Innovative Three-Stage Amplifier Circuit Brings Your Music to Life While some hi-fi makers take a shortcut to amplified audio with the use of cheap all-in-one IC chips, the resulting sound is often compromised once you turn the volume up. Instead, on the A-9030, Onkyo uses the same Three-Stage Inverted Darlington Circuitry technology it uses in its high-end A/V receivers and Reference Series hi-fi separates. This innovative circuit topology facilitates high speaker-driving power, reduces distortion, and preserves the buoyancy and expressiveness of recorded music—a unique characteristic of our low negative feedback amplifiers. Optimal Gain Volume Control Guarantees Cleaner Sound Conventional volume-attenuation methods involve initially dropping a signal close to the amplifier’s natural noise floor at low volumes. The signal can then become tainted with noise, which subsequently gets amplified along with the signal. Onkyo’s Optimum Gain Volume Control 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, and the result is noticeably clearer sound when compared to conventional amplifier designs. Phase-Matched Bass Boost for Deeper Bass and a Clearer Mid-Range From the warm low notes produced by a cello to the deep frequencies of electronic music, a good amplifier should be able to deliver plenty of bass without distorting. Some amplifiers are prone to the effects of phase shifting, which can overwhelm middle frequencies and muddy the overall sound. Our Phase-Matching Bass Boost technology effectively preserves mid-range clarity—allowing vocals and strings to shine—while maintaining a smooth, natural bass response at all volume levels. Discrete Output Stage Circuitry Means Cooler Running Temperatures A receiver’s ability to deliver high power into low impedances is a vital factor in its performance. If the current flow through the amplification circuit is inconsistent, audio quality will suffer. Onkyo stereo amplifiers feature separate high-quality components at the signal output stage. Discrete transistors help guarantee a consistent, stable supply of current to the speaker system for an open and assured performance, with less chance of distortion and cooler running temperatures. High-Output Power Supply to Drive Your Speakers At the heart of all our amplifiers, you’ll find a power supply that can maintain or increase output power as required. Musically, this means that you have deep, powerful bass; wide-ranging dynamics; musical peaks that sound composed; and correct timbre and sound staging.
