Dedicated Single-Ended Amplifier for All Types of Audio Sources Since this device employs a dedicated single-ended amplifier, it provides excellent response in the amplification of single-ended analog sound from all kinds of audio sources such as CD players and D/A converters. By fully utilizing single-ended amplification, the A-S1100 transparently draws out the intrinsic qualities of your favorite audio devices, including those made by other manufacturers.
All-Stage Full Discrete Configuration for Strong Reproduction of High NotesThis amplifier adopts an all-stage, fully-discrete configuration through all sound circuit stages using only the most meticulously selected, high-precision parts from input to output (applicable during tone control circuit defeat). The slew-rate of the audio signal has been improved to bring lively and strong response to high musical notes. Moreover, the tone control circuit lets you switch to the defeat-state and enable a full discrete configuration that bypasses the op-amp IC of the internal circuit, simply by setting the BASS / TREBLE knobs to their center points. Thorough Low-Impedance Design Ensures Powerful Bass Response with an Extremely Dynamic and Energetic FeelBy strengthening the capacity of the high-current route (raising the section area of the cable core wire to about 60% of that of the A-S1000) and by pursuing thorough low-impedance design and forming screw-clamped wire connections of major ground points, the A-S1100 boasts excellent speaker drive power with a damping factor of more than 250 (8Ω, 1 kHz). Along with the large capacity power source transformer equipped with an EI core, this design delivers bass reproduction that is both strong and uplifting. Superior Quality Electronic Volume Control for Optimum SoundWe’ve utilized a high-quality digital volume control specially designed by New Japan Radio Co., Ltd., which consists only of ladder-type resistance, removing the impact of slew-rate decline or coloring of the sound. This delivers higher purity in the sound and excellent, fast response to large volume changes and steep transients. Moreover, the tone controls employ a triple-parallel method, minimizing the detrimental impact on sound quality seen with straight-line tone controls. In addition, the bass, treble, and common circuits each utilize simple construction in which the NFB of the amp is not used and the CR elements are simply fixed in a straight line. This ensures exceptional sound reproduction even when tone control is applied. When tone defeat is applied, straight signal flow from one volume circuit to a discrete configuration buffer amp is achieved.
Discretely Configured Phono PreampThe phono preamp is comprised of a MC head amp and an equalizer amp, each of which are discretely configured, resulting in a rich sound with pronounced musicality when playing vinyl records with both MC and MM phono cartridges. Level Meters Visually Reflect the Dynamics in the MusicThe center of the main unit features level meters that provide visual enjoyment of the music with rapid or delicate movement of the needles. The meter is illuminated softly from inside by LEDs, giving a warm, beautiful lamplight look. The meter indicators, along with VU display, can be switched to show peak power as well, according to your preferences. The meter’s window has been precision-fit to the panel and lays completely flat with no gaps for an elegant and beautiful appearance.
Original Speaker Terminals Combine Ease of Use and Beauty with High-Quality SoundOur meticulous obsession with quality continues through to the speaker terminals, which are the last and crucial link in the audio chain. The screw-type terminals with originally-designed handles are created by cutting pure brass. This enables a secure connection with no reduction in sound quality. Contoured to the shape of human fingers, they not only look beautiful, they can be turned easily and fastened tightly with minimal effort. They are also compatible with connections that use banana plugs. Remote Control with Simple Design and Superior Texture
