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.
The negative effects of phase-shift—or the timing difference between sound waves of different frequencies—can sometimes be heard in audio players when corners are cut in order to increase bass response. While most audio systems have some form of low-frequency enhancement system, often a bigger bass sound comes at the expense of mid-range clarity, and results in a smeared or muddy sound. Our Phase-Matching Bass Boost technology avoids this problem by improving the phase timing to preserve the natural clarity of the mid-range—allowing vocals and strings to shine—while maintaining a smooth, powerful bass response at all volume levels.
