Niles Audio Explore Performance and Flexibility of Niles SI-1200 and SI-1260 Systems Integration Amplifiers
Page 3

INTRODUCTION

Designed for use in high-end/high-powered distributed audio systems, the SI-1260 Systems Integration Amplifier provides a level of performance, flexibility, and ease of installation previously unavailable to custom installers. The SI-1260's unique design enables each of its channels to be independently configured to reproduce stereo or mono in any combination, as well as to compensate for differing volume levels in rooms of different sizes. Additionally, the amplifier's Dual Bus Matrix™ feature and multiple inputs enable it to be used in several different applications simultaneously if desired (i.e. mono background music in some rooms and stereo in others).

As you read this manual and become more familiar with the SI-1260's capabilities, you will understand why our multi-channel amplifier design has won many presti- gious industry awards. The first multi-channel amplifier introduced by Niles, the SI- 1200, was selected Best New Product in 1994 by both Sound & Video Contractor Magazine and the Custom Electronic Design and Installation Association (CEDIA). In addition, the SI-1200 also won the Consumer Electronics Show's Innovations '95 Design and Engineering Award.
