The Sbooster Ultra MKII is designed as an additional upgrade for the BOTW P&P ECO MKI and MKII power supplies. The Sbooster Ultra MKII has to be connected directly to the Sbooster split-current module of the BOTW P&P ECO. The innovative electronic design filters and optimizes the input power and is fine-tuned within the audible reach. The Ultra MKII circuit uses upgraded input and output buffers with a higher capacity and solid conductive polymer capacitors to lower the output ripple and to expand the bandwidth of the filter circuit.
