Free Shipping on the Niles SI-245 : 2 Channel High Current Amplifier FEATURES AND BENEFITSReal World PowerThe SI-245 delivers 45 watts per channel at 8 Ohms and 70 watts per channel at4 Ohms. Youll get tremendous bass and dynamics from every pair of speakerspowered by an SI-245.Transparent SoundThe audio circuitry of the SI-245 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 withphenomenal imaging.Freedom From CrosstalkEach channel of the SI-245 is powered via its own independent power supply. Thisincreases the isolation between the two channels, and minimizes cross talk guaranteeing you absolute silence as the backdrop to your music.Current For Reactive LoadsThe high current design of the SI-245 assures that even unusual and reactive loads are handled with aplomb (a massive toroidal transformer with two separate windings, one for each of the independent power supplies, provides more than ample currentto your system).Freedom from Fan NoiseThe oversized heat sinks inside the SI-245 allow the amplifier to stay cool even whenoperating into low impedance loadswithout the noise of fan-cooled amplifiers.Independent Level ControlsEach channel has its own independent level control enabling you to preciselymatch the SI-245 to the rest of your system. The level controls also enable you tolimit the volume, preventing abuse of the system.Lifetime ConnectionsThe SI-245 features stereo inputs, cascade stereo outputs, and five-way bindingposts which are all gold plated to ensure perfect connections without corrosion foryears to come.Turn-On ModesThe SI-245 features three turn-on modes: 1. Music Sense 2. External Voltage Trigger 3. Manual Turn-On via the front panel switch. You can configure the SI-245 to interface with any kind of system and have the unit automatically turn on.Automatic ProtectionThe SI-245 is equ
