This is the workhorse, Arcam DIVA P-1000, 7 CH 135W/CH highly acclaimed power amplifier. Plenty of power for any multi-channel application, including 2 Channel Music listening. 2 years old. Light use. Smoke free, pet free home. Triggers off 12V, gain sensitivity switches on every channel, Balanced (XLR) and SE (RCA) inputs, with in/out feature allowing for cabling simplicity in whole house audio applications. Beautiful amp,sorry to see it go. Operates flawlessly, runs very cool, can be put in a cabinet (unlike MANY 7 CH amplifiers of any real power).
