PF-2502 FLAG SHIP 2-CHANNEL POWER AMPLIFIER

The PF-2502 utilizes the same amplification modules as used ADA's heralded MPA-502 in conjunction with a power supply to support two channels. Both amplification modules and power
supply reside in a single chassis.
The PF-2502 can be added to an MPA-502 for seven channels of home theater power amplification. Alternately, the PF-2502 can also be used for sound reinforcement in a multi-room
system or more basic two-channel audiophile stereo system.
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.
