1650

We call the SI-1650 a Systems Integration Amplifier because it is a power
amplifier specifically designed to solve the problems of interfacing with
different brands and models of equipment, different acoustic environments in
different rooms, and different kinds of applications: home theater, stereo, and
background music. The Niles SI-1650 Systems Integration Amplifier brings
extremely high current power to a custom installed A/V System in a remarkably
convenient way.
