Amplifier

Features

High-quality sound with low loss. Yamaha Digital Amplifiers keep power consumption to a minimum without sacrificing sound quality, which is why they are used in a wide range of applications.

Mobile

The “pure pulse direct speaker drive circuit” is filter-less, and features independently developed, advanced technologies such as a “non-clip TM function” that enables maximum power output without distortion even when battery voltage fluctuates.
