About this product
Product Information
The SI-275 is a member of the award-winning Niles Systems Integration Amplifier family. It is designed for home theaters and whole-house audio systems requiring high power. Niles specifically created the Systems Integration Amplifiers to solve the problems installers face when incorporating different brands and models of equipment into different acoustic environments in home theater, stereo, and background music applications. The SI-275 brings extremely high current power to a custom installed A/V system in a remarkably convenient way.Each channel of the SI-275 is powered by its own independent power supply. This increases the isolation between the two channels and eliminates cross talk, guaranteeing you absolute silence as the backdrop to your music. The SI-275 features gold-plated stereo inputs. Additionally the cascade stereo outputs and the five-way binding posts are also gold-plated to ensure perfect connections without corrosion for years to come.The SI-275 delivers 75 watts per channel at 8 Ohms and 100 watts per channel at 4 Ohms. You'll get tremendous bass and dynamics from every pair of speakers powered by an SI-275. The audio circuitry of the SI-275 is constructed using the finest parts available; including 1% metal film resistors, high quality capacitors, and oversized heat sinks. All this attention to technical detail creates a sound that is clear and uncolored with phenomenal imaging.The SI-275 can be turned on in three different ways: with a newly improved and field tested music-sense circuit which activates from even the softest musical passage; voltage turn-on (3-30 volts, AC or DC); or manually from the front panel. The high current design of the SI-275 assures that even unusual and reactive loads are handled with ease. A massive toroidal transformer with two separate windings for each of the two power supplies delivers more than ample current to your system.Product Identifiers
