2018 NEW PRODUCT RELEASE
A-9110 Integrated Stereo Amplifier
Versatile pre-main amp refreshes your music life
Onkyo builds on the success of its A-9010 pre-main amp with the new A-9110
Integrated Stereo Amplifier, a component that refines an original amp design
that’s won an excellent critical and commercial reputation for dynamic,
musical sound. Lively dynamics, deep bass, and layered detail emerge from warm
and expressive tuning sure to please European ears. WRAT delivers high-current
power stability via large custom capacitors, while low-NFB amps capture the
depth and spatiality of analog and hi-res recordings. Five RCA inputs
including MM phono stage connect your sources while high-quality speaker-posts
reveal Onkyo’s hi-fi heritage and careful attention to detail. The A-9110
invites you into each album, the hours passing comfortably in pure analog
sound.

A-9110 Integrated Stereo 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 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 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 clearest sound at 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 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 on 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 1.6 mm. Working together
with large, wide-spaced insulators, unwanted resonance is virtually
eliminated.
Direct Mode brings you closer to the source
Direct Mode bypasses tone and PM Bass circuitries. In combination with a
refined amp circuit design, signal-pathlengths have been significantly reduced
in comparison to the A-9010 for even more accurate and faithful sound. Enjoy
end-to-end analog music reproduction from turntable to speakers, and recapture
the atmosphere of the original recording with any connected source.
New fine display shares info clearly
A new display panel boasts fine text resolution, making it easier to read at a
distance than single bulbs. It shows active selected input at a glance.
Quality speaker posts
make perfect contact
Speaker cables with your choice of the terminal are firmly secured by high-
quality speaker binding posts. Each wide-spaced non-magnetic post prevents
interference and features a large, easy-to-grip transparent knob.
