About this item
Written by Crutchfield's Dave Bar
The choice of pros since 1978
When professional installers need versatile and rugged components they can depend on, they turn to Niles. Niles' Systems Integration Amplifiers® are powerful tools that simplify and optimize complex custom multi-room installations. While traditional receivers and amplifiers work well in typical stereo and home theater systems, multi-room systems require an amplifier that does more than just drive speakers — these systems require an approach that offers greater flexibility and performance.
Power and performance to spare
Whether you're using the Niles SI-2150 as a part of a multi-room audio system or as the amplifier in your main listening room, you'll find that it delivers plenty of pristine, dynamic stereo power. Its high-current design allows it to handle unusual and reactive loads with ease, including the ability to safely drive up to three pairs of directly connected 8-ohm speakers at the same time. And it's not just all muscle. Niles uses high-quality parts throughout to ensure that you'll always get top-notch audio performance. Cutting-edge, independent digital power supplies for each channel prevent cross-talk interference, ensuring clean, spacious sound. Oversized heat sinks keep the SI-2150 cool even when driving heavy loads, eliminating the need for a noisy cooling fan and guaranteeing silent operation.
Installer-friendly features
Niles knows what it takes to stay competitive in the world of custom installation. That's why their amps include features that make them easy to integrate. You get three separate turn-on modes to bring the amp to life, plus a 12-volt DC control output to activate other devices such as motorized screens and curtains. Independent level controls for each channel allow precise volume matching to the rest of the system, and can also be used to limit volume to prevent speaker damage. Handy cascade audio outputs let you daisy-chain mutiple amps together. And you can even combine its two channels into one to give your speakers more juice — a great option for power-hungry outdoor speakers.
