Yamaha M-2 Amplifier Specification

The Yamaha M-2 Amplifier, a solid-state power amplifier, exemplifies high-fidelity audio performance with robust construction and advanced engineering. Featuring a dual-mono design, the M-2 ensures optimal channel separation and sound clarity. It delivers a powerful output of 240 watts per channel into 8 ohms, ensuring ample power for a wide range of speaker configurations. The amplifier's frequency response ranges from 20 Hz to 20 kHz, providing a comprehensive audio spectrum with minimal distortion.

The total harmonic distortion is impressively low at 0.005%, reflecting the M-2's ability to maintain audio purity even at high volumes. Signal-to-noise ratio stands at 120 dB, guaranteeing a quiet background and highlighting the subtleties in music playback. The amplifier employs a direct-coupled design with no capacitors in the signal path, which further enhances audio fidelity by reducing phase distortion.

A heavy-duty toroidal transformer is incorporated to ensure stable power delivery, minimizing fluctuations and enhancing dynamic performance. The M-2 also features large heat sinks for efficient thermal management, allowing it to operate reliably even during extended listening sessions. With its classic brushed aluminum front panel, the M-2 combines aesthetic elegance with functional design, including intuitive controls for ease of use.

Connectivity options include gold-plated speaker terminals and inputs to reduce connection loss and improve signal integrity. The Yamaha M-2 is renowned for its durability and consistent performance, making it a preferred choice for audiophiles seeking both power and precision in audio reproduction. Its legacy in the high-end audio market underscores its commitment to delivering an exceptional listening experience.

Yamaha M-2 Amplifier F.A.Q.

How do I connect speakers to the Yamaha M-2 Amplifier?

To connect speakers to the Yamaha M-2 Amplifier, use high-quality speaker wires. Connect the positive (+) and negative (-) terminals on the amplifier to the corresponding terminals on the speakers, ensuring a secure connection to prevent any signal loss.

What is the recommended maintenance routine for the Yamaha M-2 Amplifier?

Regularly dust the exterior and ensure proper ventilation to avoid overheating. Annually inspect and clean the internal components, such as the heat sinks and circuit boards, using compressed air. Ensure all connections are tight and free from corrosion.

How can I troubleshoot if there's no sound coming from the amplifier?

Check all connections to ensure they are secure. Verify that the input source is correctly selected and functional. Inspect the speaker wires for any damage. Ensure that the amplifier's protection mode is not activated, which might require resetting the unit.

Can I use the Yamaha M-2 Amplifier with a turntable?

Yes, you can use the Yamaha M-2 Amplifier with a turntable. However, ensure your turntable has a built-in preamp or use an external phono preamp to connect the turntable to the amplifier.

What should I do if the amplifier overheats?

First, turn off the amplifier and let it cool down. Check the ventilation around the unit and ensure the cooling fans are working if applicable. Avoid placing the amplifier in enclosed spaces and ensure it has adequate airflow.

How do I clean the Yamaha M-2 Amplifier without damaging it?

Use a soft, dry cloth to wipe the exterior. For stubborn dirt, slightly dampen the cloth with water. Avoid using chemical cleaners or solvents. For internal cleaning, use compressed air to remove dust from components.

Is it possible to bi-wire speakers with the Yamaha M-2 Amplifier?

Yes, the Yamaha M-2 Amplifier supports bi-wiring. To bi-wire, connect separate wires to the high-frequency and low-frequency terminals on the speaker and connect them to the corresponding terminals on the amplifier.

What type of input sources can I connect to the Yamaha M-2 Amplifier?

The Yamaha M-2 Amplifier can be connected to various input sources such as CD players, tuners, DACs, and streaming devices, as long as they have compatible output connections like RCA or balanced XLR.

How do I adjust the sound settings on the Yamaha M-2 Amplifier?

The Yamaha M-2 Amplifier itself does not have tone controls. Sound adjustments must be made on the connected source device or through an external equalizer if desired.

What are the indications of a blown fuse in the Yamaha M-2 Amplifier and how do I replace it?

Indications of a blown fuse include the amplifier not powering on. To replace it, unplug the unit, locate the fuse holder on the back panel, remove the blown fuse, and replace it with a new one of the same rating.
