The Yamaha M-5000 two-channel power amplifier has an uncompromising design, typical of High End models. The device is made using balanced circuitry with complete separation of the left and right channels, and is capable of working effectively even with the most complex acoustics. The real decoration of the front panel of the amplifier is the large pointer signal level indicators behind Asahi glass and pleasant backlighting.
Key Features:
- 200W + 200W (4 Ohms, 20Hz-20kHz, THD 0.07%, 2 channels)
- 100W + 100W (8 Ohms, 20Hz-20kHz, THD 0.07%, 2 channels)
- Carefully designed balanced signal transmission system
- Ungrounded and balanced layout for improved amplification quality
- Symmetrical construction with full separation of left and right channels
- Low impedance due to shortened signal and power transmission paths
- Enhanced design for excellent reliability and stability
- Massive toroidal transformer
The amplifier is equipped with balanced and unbalanced inputs. Both stereo channels in the Yamaha M-5000 have a fully symmetrical layout, which ensures reliable stereo channel distribution. At the same time, the amplifier circuit implements the concept of reducing signal transmission paths, which further reduces noise and distortion.
Unlike conventional power amplifier designs, the Yamaha M-5000 has an isolated (floating) ground supply circuit, which eliminated the unwanted effects of voltage fluctuations or common wire noise on the audio signal. Yamaha M-5000 output stages utilize MOSFET field-effect transistors to improve the amplifier's performance with low-impedance speakers. The power supply of the Yamaha M-5000 terminal amplifier features a massive toroidal transformer on a 3mm thick pure brass base. Thick wires and screw connections facilitate lossless transmission of high current from the power supply to the amplifier circuitry and then to the speakers. As a result, when the load resistance is changed from 8 to 4 ohms, the output power of the unit doubles, which indicates the high quality of its entire power section. To obtain even higher output power, the amplifier can be switched to bridge mode.
The Yamaha M-5000's chassis is designed with a “mechanical grounding” concept, with all massive components attached directly to the chassis frame. Custom-made brass amplifier supports provide additional vibration isolation for the amplifier. They work just as effectively as spike supports, but are completely safe for the surface on which the amplifier is mounted. The unit has a trigger input and output, as well as an automatic trigger system when a signal is input.
