Audio Amplifier for Mobile Phone and GPS

The portable "Pro Audio Booster" amplifies weak or too quiet headphone output signals by 8 times the volume, so that music reproduction devices such as IPhone/IPod, CD, MD, MP3, navigation systems, USB sticks and WalkMan can be heard very well even in noisy environments. An integrated equalizer circuit also provides for the amplification of strong basses, dynamic mids and excellent highs. The frequencies lost due to music compression processes are interpolated and thus brought to a much more dynamic overall sound.
