Enjoy high-resolution stereo sound with the Onkyo A 9150 2-Channel 120W Home Theater Power Amplifier.

It delivers up to 60W per channel at 4 Ohms and has two optical inputs, two digital coaxial inputs, a dedicated phono input, and five stereo RCA inputs. The A-9150 features an integrated DAC and a front-panel 1/4" headphone jack.

Designed for Enhanced Power Amplification

In order to deliver a clear and comfortable audio image, sounds of different frequencies should arrive at the listening position simultaneously. The power amplification circuits in the A-9150 feature topology that's designed for phase accuracy, wide-spectrum signal reproduction, and natural transient response.

Enhanced Musicality with Discrete SpectraModule

The discrete SpectraModule features a slew rate of over 500 V/μs to help produce accurate definition of instruments ranged around a larger and more realistic soundstage.

Dedicated MM/MC Phono Circuit Board

The A-9150 features a gold-plated phono input that supports signals from either MM or MC cartridges fitted to your choice of turntable. Its separate phono circuit board has dedicated equalizers served by a customized head amp, which operates in discrete configuration for MC signals. Together with analog power amplification, this phono input design helps express the depth and vitality of music on vinyl.

High-Current Transformer and Capacitors

Current influences sound quality; high current is required for a better grip on the speaker transducers, improving control and accuracy. A high-output transformer and two capacitors inside the A-9150 deliver current through discrete output-stage transistors that are kept cool by an aluminum heat sink. This allows the speakers to react nearly instantly, with throw-range controlled for accurate articulation, even through dynamic and complex musical passages.

DIDRC Filter and 768 kHz / 32-Bit DAC for Natural Sound

Distortion in the ultra-high-frequency spectrum can have a noticeable impact on the character of audible sound. The DIDRC Filter is designed to completely erase ultra-high-frequency noise. Performance is optimized for digital music with an undistorted frequency response extending above the range of audibility. Combined with a 768 kHz / 32-bit DAC, you can enjoy an enhanced sense of realism from digital sources, with none of the unnatural "synthesized" feeling sometimes produced by digital processing.

Designed for Enhanced Quality with Reduced Resonance

Held in place by a flat chassis designed to tame resonance, the digital audio board is isolated from the analog circuitry. The L/R channels are symmetrical to equalize signal path-lengths and minimize stereo playback errors. The coaxial digital inputs, phono input, speaker posts, and RCA line inputs are gold-plated to prevent corrosion and improve connectivity. The A-9150 is finished off with an aluminum front panel and volume control.
