Using original TPA3116 and CSR4.0 Bluetooth module Coupling capacitance by Germany's Siemens 1UF Signal main circuit electrolytic capacitor Taiwan brand names, the main filter capacitor electrolytic capacitors imported from Japan to ensure strong support for a steady stream of power. Resistance selection Rings metal resistance, the main circuit employs a precision of ± 1% metal film resistors rings, ensure the machine a good signal to noise ratio. 1.6mm thick sheet using double-sided PCB, 2.0 oz copper thickness, HASL whole process to ensure that the size of the current through the good performance. PCB-class quality. Fully enclosed dust-proof potentiometer, the performance is more stable, more durable than ordinary potentiometer! Using fully shielded audio-specific high-current inductors, to ensure crisp and powerful sound. Using the latest Bluetooth version 4.0 Connectivity Bluetooth connection methods and general equipment like! Search equipment (YJHIF) - point (YJHIFI) connected devices - Play music.
