Pyle Pro's PCA1 amplifier was designed with today's music lover in mind. The PCA1's smart, compact design fits neatly on top of a computer tower or next to your laptop to power personal audio speakers. MP3 player or iPod headphone outputs may also be used as an amplifier source with the use of a 3.5 mm stereo plug to dual RCA jack adapter. A very linear wideband frequency response means you won't miss a signal note of a song, and two-channel four-ohm stability allows you to use this amplifier with a wide range of speakers. There is no need for a separate power supply; Pyle Pro has built it into the chassis. Switchable support for both North American 120 VAC and European 230 VAC is included as well.
