Niles SI-245

Stereo power amplifier


In very nice condition. Original box and packing are not inlcuded. Manual is on line.

Multi-room audio systems operate better when you use an amp that offers greater flexibility than a typical stereo amp. If you own a receiver with a second-zone preamp output, the Niles® SI-245 is the perfect power amp for those second-zone speakers. Or as a stand alone amp!

You get 45 high-current watts RMS per channel and 4-ohm stability — connect two pairs of 8-ohm speakers in parallel without worrying about overloading the amplifier or speakers.
