Niles SI-1230 - 12 Channel Amplifier

We call the SI-1230 a Systems Integration Amplifier because, for the first time, a power amplifier has been 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. As you read this manual and become more familiar with the capabilities of the SI-1230 you’ll understand why its predeccesor, the SI-1200, was selected Best New Product by Sound & Video Contractor Magazine and CEDIA (Custom Electronic Design and Installation Association). In addition, the SI-1200 also won the Consumer Electronics Show’s Innovations Design and Engineering Award.
