Phass is the car audio division of FT Trading Ltd. which is based in Nagano, Japan. we began our foray into car audio when, believing that we could produceproducts that surpassed the sound quality of products we previously heard, we began the development of the RE2 amplifier, in the Spring of 1994. The RE2, which functions as a constant current driving, non-negative feedback amplifier, was completed in 1996 and Phass was born.
