DESCRIPTION:

The very basic and the most important need of a power amplifier is an extremely good power supply or the power bank. It is impossible for even the best amplifier circuit to give the desired output if it isnt backed by a good power supply. A power supply circuit basically consists of a rectifier circuit plus a capacitor bank for storing the rectified power . What we have here is a very high quality power supply module that not only serves as an effiecient power bank but also has a built in speaker protection system and a secondary power for driving all the smaller circuits inside a DIY amplifier. This is one of those High quality Products found inside hi-end audio components.

This Version does not inlude the six main capacitors . The user can add any capacitors of the preffered brand having a rating of 10000uF/63v

Please note that this product has been made avaliable directly from the manufacturer and not from any reseller / e-shop, thus we can assure you its a 100 percent original product with all good / original components. we are the direct distributors for XD products in india
