YJHiFi YJ00320 TPA3116 2.1 Bluetooth 4.0 Digital Power Amplifier 2x50W+100W Class D Audio Amp for Home Theater Car Speaker – Blue

Description

Features: Using original TPA3116 and CSR4.0 Bluetooth moduleCoupling capacitor uses German Siemens 1UFThe main circuit of electrolytic capacitor signal adopts famous brand from Taiwan, and the main filter capacitor adopts Japanese ELNA electrolytic capacitor to ensure strong and continuous power supportThe resistance uses five-ring metal resistors, and the main circuit uses a five-ring metal film resistor with an accuracy of ±1%, which ensures a good signal-to-noise ratio of the whole machinePCB adopts 1.6mm thick double-sided board, 2.0 oz copper thickness, and full tin spraying process to ensure good passing performance of large and small currents. First-class PCB qualityThe fully enclosed dust-proof potentiometer has more stable performance and is more durable than ordinary potentiometersThe red-gray ring audio special high-current inductor is used to ensure the sound is clear and powerfulThis machine adopts an all-aluminum chassis, and the surface of the chassis is treated with wire drawing oxidation coloring processThe external gold-plated Bluetooth antenna has better receiving ability and the receiving range is 10 metersThe way to connect to Bluetooth is the same as that of ordinary devicesThe input methods include Bluetooth and analog input. When the two methods are input at the same time, the Bluetooth input has priority. When analog input is required, please turn off the Bluetooth function of the mobile phone to switchAppearance size: knob to antenna 220*width 130*height 45MM (without antenna) antenna height 11CMWorking method: Class DQuiescent current: 50mAWork efficiency: 90%Rated output power: 100W+2*50WFrequency response: 20Hz to 20KHzWorking voltage: DC18V to DC24VMaximum output current: 3A Package Included: 1 x Power Amplifier
