5NILES AUDIO CORPORATION – 1-800-BUY-HIFI – 1-760-710-09922 ChAnnEL, BRIdgABLE PowER AMPLIFIERSFEATURES ANd BENEFITSREAL wORLd pOwERThe SI-250, the SI-2100 and the SI-2150 deliver 50 watts, 100 watts, and 150watts per channel at 8 ohms and 100 watts, 220 watts, 270 watts per channel at4 ohms respectively. You’ll get tremendous bass and dynamics from every pairof speakers connected.TRANSpARENT SOUNdThe audio circuitry of the Niles System Integration Amplifiers® is constructedusing the finest parts available; including 1% metal film resistors, high qualitycapacitors, and oversized heat sinks. All this attention to technical detail createsa sound that is clear and uncolored with phenomenal imaging.FREEdOm FROm CROSSTALkEach channel of the Niles System Integration Amplifier is powered via itsown independent power supply. This increases the isolation between the twochannels and eliminates cross talk, guaranteeing you absolute silence as thebackdrop to your music.CURRENT FOR REACTIvE LOAdSThe high current design of the Niles System Integration Amplifiers assures thateven unusual and reactive loads are handled with ease. A massive toroidaltransformer (SI-250) and cutting edge digital power supplies (SI-2100, SI-2150)provide more than ample current to your system.FREEdOm FROm FAN NOISEThe oversized heat sinks inside the System Integration Amplifiers allow theamplifier circuitry to stay cool even when operating into low impedance loadswithout the distracting noise created when using fan-cooled amplifiers.INdEpENdENT LEvEL CONTROLSEach amplifier channel features an independent level control enabling precisevolume matching to the rest of the system. These level controls can also limitvolume to prevent abuse of the system.9901253-Rev-A-SI-2150Manual.indd 5 6/8/12 9:43 AM
