The digital fluorescent output display of this amplifier lets you know visually that the levels are where you like them. The HB-2502U has USB and SD card inputs, as well as an iPod/MP3 input, so that you can plug right into this amplifier and play your songs on your stereo system. The HB-2502U has 7.2 channels, all of which upconvert analog audio sources to digital quality. The HB-2502U has the same specs as the lower cost HB-1502U, but with 2500 watts of peak power instead of just 1500 watts. However, the HB-2502U does not match the higher cost HB-3502U's 3500 watts of peak power. Like the HB-3502U and HB-1502U, the Technical Pro HB-2502U comes with a remote control.
