Audio Design Associates PTM-850-BAB

The PTM-850 is a eight-channel high performance power amplifier designed for use in home theater and multiroom applications. Handcrafted in the United States to the rigorous quality and performance standards established by Audio Design Associates, the PTM-850 matches perfectly with the ADA Surround Sound Preamplifiers such as the Cinema Rhapsody or Suite 7.1.

The PTM-850 can also be used to in ADA multiroom systems such as Suite 8 x 8 to power speakers in four separate zones. The PTM-850’s moderate power capability make it an excellent choice for driving speakers in rooms that can be powered adequately with the 50 watts available with each channel of the PTM-850.

The PTM-850 can be triggered on and off with an external 5 Vdc to 12 Vdc trigger source. This facilitates simple one touch operation to power on the home theater or multiroom system. The streamlined design of the PTM-850 occupies only one rack space in a standard 19-inch equipment rack.

At Audio Design Associates, we have been designing and building high-performance audiophile quality components for use in custom installation applications for 25 years. We’re proud to offer this exceptional power amplifier that will provide many years of trouble-free operation.
