Overview
The CA-M400 is a 400W monaural amplifier. Balanced throughout, the CA-M400 also uses these 200W modules, but con?gured in balanced output mode. One module amplifies an inverted signal while the other handles a non-inverted signal. Our balanced output stage cancels noise and distortion and yields higher power without reducing low impedance drive capability. Music lovers seeking the benefits of high-end monaural amplifiers and multichannel enthusiasts who can afford the price of admission will and the CA-M400 an ideal choice for a no-compromise Delta series Classé audio system.
