A-9030
Integrated Stereo Amplifier
A High-Value Proposition for the Passionate Music Fan
For those taking their first steps into the world of hi-fi audio, there’s no better component to start with than the A-9030 Integrated Stereo Amplifier. Featuring Onkyo’s Wide Range Amp Technology—augmented by Three-Stage Inverted Darlington Circuitry to reduce distortion and increase driving power—the low negative feedback design breathes life into your recordings, where conventional amps sound flat and dull by comparison. Another point of difference lies in its ability to boost bottom-end response. Rather than obscuring the frequencies that typically carry vocals, a new system phase-matches the bass to preserve a crystal clear mid-range. As well as sounding great, the amplifier has a heavy-duty transformer and twin capacitors to deliver enough power to drive your loudspeakers with depth and dynamism. Good quality analog inputs and banana plug-compatible speaker posts are found on the rear panel to connect your CD player, tuner, turntable, and speakers, while the front panel has classic-style knobs for bass, treble, balance, and input selection. Wrapped in a 1.6 mm-thick anti-resonant chassis, and boasting an aluminum faceplate, this high-value stereo amp exudes the build quality for which Onkyo is famous.
WRAT (Wide Range Amplifier Technology) for Naturally Vivid Sound
Onkyo developed the WRAT suite of technologies to improve the clarity and character of amplified audio. 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.
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.
