High Quality Circuit Design Based on the ToP-ART (Total Purity Audio Reproduction Technology) Concept
The amplifier design technology from Yamaha is called ToP-ART which features an input to output with a direct symmetrical design. ToP-ART design and ART Base ensure optimum sound when processing and transmitting the audio signal. The signal is simple and direct, therefore it is less likely to be affected by noise and distortion. The left and right channels are organized in a straight, symmetrical layout for the highest signal purity. In addition, the ART (Anti-Resonance and Tough) Base bottom chassis and a solid center bar provide high rigidity support and dampers vibration. These design innovations contribute to this amplifier's rich audio reproduction with abundant musicality.
High Quality Parts for Outstanding Audio Performance
Notice the custom made power transformer, custom made block capacitors, two direct signal path speaker relays, one point grounding system, extruded aluminum heat sinks and other top quality parts to effortlessly handle demanding audio conditions. The quality of each individual part, as well as how they work together, basically determines the sound quality of this component. Yamaha uses only very high quality parts, carefully selected and tested for their sound properties.
Created by Rich Experience, Tradition and High Technological Expertise
Yamaha, with a long history of over 125 years as a musical instrument maker, also has a high reputation for Hi-Fi components. The A-S501 is created by taking advantage of this rich experience and high technological expertise. Based on the concept of “Natural Sound” for reproducing all music as it really sounds, this amplifier is built with scrupulous care from its circuit design to basic sound production.
Pure Direct Mode for Greater Sound Purity
The Pure Direct mode causes the audio signal to travel the shortest possible circuit route, bypassing the buffer amp, the tone, loudness and balance controls to virtually eliminate any signal degradation for the purest sound quality.
Continuously Variable Loudness Control
The A-S501 also features a new analog loudness control on the front panel that uses electronic volume for higher sound quality which lets you adjust the loudness effect as desired. Separate from the overall volume, this controls the balance of the low and high frequencies providing full tonal range at any volume level by compensating for the natural loss in the human ear at soft levels.
Gold Plated Terminals
Gold plated terminals ensure a high quality connection that prevents signal loss. The A-S501 has gold plated speaker and input terminals.
Connection for YBA-11 Bluetooth® Wireless Adapter (Optional Accessory)
With the YBA-11, you’ll be able to stream music wirelessly from a Bluetooth® compatible mobile phone or a PC. Thanks to the digital coaxial connection and the aptX® audio coding algorithm, you will enjoy wireless music streaming with optimum sound quality. You can also conveniently power the YBA-11 via the DC out connection on the rear panel of this amplifier.
Speaker A, B or A+B Selection and Speaker Terminals for Two Systems
You can connect two separate speaker systems and hear them in different rooms at the same time. There are four terminals, so by just rotating a simple selector dial you can switch between the two pairs of speakers to play the selected source.
Subwoofer Terminal
A terminal for connecting a subwoofer is provided, allowing you to increase the bass output of your system for a more powerful sound with better overall sound quality.
Rotary Encoder Input Selector with LEDs
The rotary encoder makes it quick and easy to select input sources. The luxurious hairline finish offers a nice tactile feeling. LEDs clearly show which source is selected so you can easily switch sources, even in a dark room.
AudioQuest Jack Russell Subwoofer Cable - 13.12 ft. (4m)
Connect amplifiers, receivers, soundbars, and AVRs to subwoofers with a purpose-built RCA cable designed for clean, reliable signal transfer. Jack Russell features Solid Long-Grain Copper (LGC) conductors to reduce distortion caused by grain boundaries, Foamed-Polyethylene insulation to maintain dynamic contrast, and a Metal-Layer Noise-Dissipation system that helps dissipate and drain high-frequency noise away from the signal path. The result is more naturally beautiful and detailed music, more intelligible dialogue, and thrilling sound effects for home theater and music systems.
Features
- Solid Long-Grain Copper (LGC) Conductors
- Foamed-Polyethylene (FPE) Insulation
- Metal-Layer Noise-Dissipation
- Cold-Welded, Gold-Plated Terminations
- Direction-Controlled Conductors
Solid Long-Grain Copper (LGC) Conductors
The surface quality is critical because a conductor can be considered as a rail-guide for both the electric fields within a conductor and for the magnetic fields outside the conductor. High-purity LGC minimizes distortion caused by grain boundaries and maximizes linear RF Noise-Dissipation.
Foamed-Polyethylene (FPE) Insulation
Any solid material adjacent to a conductor is part of an imperfect circuit and absorbs energy. Some of this energy is stored and then released as distortion. Because air absorbs next to no energy and Polyethylene is low-loss and has a benign distortion profile, Foamed-PE, with its high air content, causes much less of the out-of-focus effect common to other materials.
Metal-Layer Noise-Dissipation
It’s easy to accomplish 100% shield coverage. Preventing captured radio-frequency interference from modulating the equipment’s ground reference requires AQ’s Noise-Dissipation. Traditional shield systems typically absorb and then drain noise/RF energy to component ground, modulating and distorting the critical reference ground plane, which in turn causes a distortion of the signal. Noise-Dissipation “shields the shield,” absorbing and reflecting most of this noise/RF energy before it reaches the layer attached to ground.
Cold-Welded, Gold-Plated Terminations
Instead of solder, the process employs a high-pressure technique. Because the ground shells are stamped instead of machined, the metal used can be chosen for low distortion instead of machinability.
Direction-Controlled Conductors
All drawn metal strands or conductors have a non-symmetrical, and therefore directional, grain structure. AudioQuest controls the resulting RF impedance variation so that noise is drained away from where it will cause distortion.
