Onkyo -A-9110 Integrated Amplifier

Stable high-current power with wide-range amplifiers

Dynamic changes in music cause impedance to fluctuate. If power can't be delivered when impedance drops, sound quality suffers. Onkyo's solution is WRAT, specifically its high-output EI transformer, huge custom-made main audio capacitors, and carefully selected high-quality parts. High-current stability controls the speaker drivers for accurate and assured reproduction of dynamic musical passages. Further, the A-9110 features Onkyo's time-proven low-negative-feedback amplifier topology that distinguishes the timbral warmth, fullness, and vibrancy of the recording. This circuitry captures a wide frequency spectrum with uncommonly low distortion.

Sounds clearer at low volumes

When playing music at a low volume, the signal normally drops close to the component's noise floor. The signal picks up noise, which is amplified, and the result is a muffled sound. To avoid this, the A-9110 features Optimum Gain Volume Circuitry, a volume circuit that requires less than half the usual amount of attenuation. The signal never approaches the noise floor, so you can enjoy the clearest sound at a low volume.

Phase Matching Bass Boost enriches sound at low volume

Most pre-main amps have a loudness button designed to boost low-mid frequency sound. However, conventional designs are prone to phase-shift, which degrades the clarity of the vocal frequency band. Onkyo's Phase Matching Bass Boost function eliminates phase-shift between low- and mid-range frequency bands above 300 Hz. Bass response is enhanced without compromising vocal clarity, and that's something especially useful when playing music at a low volume where bass and high-frequency sounds are more difficult to hear.

Thick and rigid chassis tames resonance

Every hi-fi component generates electromechanical resonance. This translates into signal noise, and that impacts the sound coming out of your speakers. To combat the negative effects of vibration, the A-9110 features a rigid metal chassis that's 1.3 times thicker than the A-9010 at 1/16" (1.6 mm). Working together with large, wide-spaced insulators, unwanted resonance is virtually eliminated.
