Ampilifier this series is designed to be input into the mini-speaker box 2, 4 and 8 ohm.rangkaian this switch is also equipped with Bass-Booster.dapat in the output path to connect the walkman, mini disc, iPod, CD Player, Computers and other devices that have similar lines to its headphone output.
In this series without using the IC design by using the methods that seemed a bit behind in jaman.Ampilfier supply voltage with 12 v.switch SW1 akan produce sound bass-booster, but at the same time the volume should be reinforced as compensation on the loss of high frequency.
