Yamaha A-S701 Amplifier Specification

The Yamaha A-S701 Amplifier is a high-fidelity audio component designed for audiophiles seeking exceptional sound quality and versatility. It delivers a robust power output of 100 watts per channel at 8 ohms, ensuring dynamic and clear sound reproduction across a wide range of musical genres. The amplifier features Yamaha's proprietary ToP-ART (Total Purity Audio Reproduction Technology) design, which includes a symmetrical layout to preserve signal purity and minimize distortion.

The A-S701 is equipped with a high-quality Burr-Brown 192 kHz/24-bit DAC, allowing it to handle digital audio inputs with precision and clarity. It offers a comprehensive range of connectivity options, including optical and coaxial digital inputs, ensuring compatibility with various audio sources. The amplifier also provides multiple analog inputs and outputs, a phono input for turntables, and a subwoofer output, catering to diverse audio setups.

A standout feature of the A-S701 is its Pure Direct mode, which bypasses unnecessary circuits to deliver the shortest possible signal path, enhancing sound purity. The amplifier's build quality is evident in its solid construction and elegant aluminum front panel, which not only enhances durability but also adds a touch of sophistication to any audio system. The inclusion of Yamaha's Variable Loudness Control allows users to adjust the tonal balance to maintain full tonal range at any volume level.

Overall, the Yamaha A-S701 Amplifier combines advanced audio technology with user-friendly features, making it a versatile choice for both analog and digital audio enthusiasts who demand high-quality sound and operational flexibility.

Yamaha A-S701 Amplifier F.A.Q.

How do I connect my Yamaha A-S701 Amplifier to a turntable?

To connect your turntable to the Yamaha A-S701, use an RCA cable to connect the turntable's output to the amplifier's "PHONO" input. Ensure the grounding wire from the turntable is connected to the amplifier's grounding terminal to prevent hum.

What should I do if there is no sound coming from the speakers?

Ensure that the speaker wires are properly connected to the amplifier's speaker terminals. Check that the input source is selected correctly and that the volume is turned up. Also, verify that the mute function is not enabled.

Can I bi-wire my speakers using the Yamaha A-S701 amplifier?

Yes, the Yamaha A-S701 supports bi-wiring. Connect separate speaker wires to the A and B outputs on the amplifier for the high and low frequency inputs on your speakers.

How do I use the Pure Direct mode on the A-S701?

To activate Pure Direct mode, press the 'PURE DIRECT' button on the front panel of the amplifier. This mode bypasses certain circuits, providing a more direct audio signal path for improved sound quality.

What is the best way to clean and maintain my Yamaha A-S701?

Use a soft, dry cloth to clean the exterior of the amplifier. Avoid using chemicals or abrasive materials. Ensure that the vents are free of dust and debris to maintain proper ventilation.

How do I reset my Yamaha A-S701 amplifier?

To reset the amplifier, turn it off and unplug it from the power source. Wait for a few minutes, then plug it back in and turn it on. This will reset the unit to factory settings.

Can I connect my Yamaha A-S701 to a Bluetooth device?

The Yamaha A-S701 does not have built-in Bluetooth capability. To connect a Bluetooth device, use an external Bluetooth receiver connected to one of the amplifier's line inputs.

How to troubleshoot distortion issues with the Yamaha A-S701?

Check if the speaker wires are correctly connected and not short-circuited. Ensure the speakers' impedance matches the amplifier's rating. Lower the volume and check if the distortion persists. If so, inspect the audio source for any issues.

What is the function of the Loudness control on the A-S701?

The Loudness control compensates for the human ear's decreased sensitivity to low frequencies at lower volume levels. It adjusts the balance between low and high frequencies for a more natural sound at lower volumes.

Why does my Yamaha A-S701 shut down unexpectedly?

The amplifier may shut down due to overheating or overloading. Ensure it is placed in a well-ventilated area and that the speaker impedance is within the recommended range. Check for any short circuits in the speaker connections.
