DESCRIPTION
Introduction:
This product adopts the original imported TPA3116D2 power amplifier chip; the main volume adjustment, using the knob encoder used in high-end audio for 360-degree stepless tuning; low-noise pre-op amplifier, high power supply rejection ratio, high AM rejection, high power conversion efficiency, high circuit board, big brand electronic components, reasonable layout, effectively reduce electromagnetic interference, make full use of effective heat dissipation area, greatly improve product performance, widely used, cost-effective, high-quality high-power Bluetooth-compatible amplifier specially provided for HIFI audiophile music.
Feature:
1. Original TPA3116D2 power amplifier chip: TPA3116D2 has AM interference suppression function; the output has a filter, HIFI sound quality, and the requirements for speakers are relatively low.
2. Bluetooth-compatible 5.1 audio power amplifier module: 2.1 dual-channel stereo output, maximum output power 2X50W, with pre-stage high and low adjustment; pure HIFI fever sound quality. The treble is pure and transparent, the midrange is gentle and delicate, and the bass is surging and shocking.
3. Classic appearance multi-function main knob: The main knob adopts the rotary encoder only used in high-end power amplifiers, and realizes 360-degree stepless tuning. The hand feels smooth, one-button start and stop, and the operation is simple and convenient by long-pressing the switch.
4. Support mobile APP control: APP visual operation play mode, support for iOS, for Android (please download it in the Google market, search for sinilink to download).
5. Supported audio input: Bluetooth-compatible 5.1, AUX, USB sound card, U disk. (U disk file system must be FAT 32, maximum support 32GB)
6. Supported audio output: active speakers, passive speakers. (note: passive speakers and active speakers can only choose one)
7. Support U disk playback: plug in the U disk, open the APP to switch the U disk mode, and with a prompt sound, enter the U disk playback mode.
8. Support computer sound card function: It can output a signal with better sound quality than the computer and connect it to the speaker for playback, connect the Bluetooth-compatible card to the computer with a data cable, open the APP, click to switch sound card to complete the switch and play with a prompt sound. Open the computer player software to play music.
9. Heat dissipation mechanism: The large-area heat sink pasted with special thermal conductive silica gel is used, and the copper-clad heat dissipation is close to the shell, and the heat dissipation area is doubled to ensure that the product runs at full power and high performance.
