Special Features
As a digital amplifier: with Bluetooth 5.0 and 3.5mm AUX inputs, compatible with most audio sources; adopts TPA3116 IC chip, output power up to 50W+50W, easily to drive most home speakers.
As an audio spectrum analyzer: adopts dedicated green VFD display screen with 25 × 15 high resolution, guarantee the accuracy of each frequency band.
As a high-precision clock: using RX8025T built-in crystal oscillator whose clock accuracy is ±3ppm, year error within 1 minutes, very cool and interesting.
HIFI sound and amazing handmade: the sound is clear and clean, high-end components are used such as WIMA capacitors to improve the sound details; with remote control, easy to adjust all settings; the placement angle of VFD spectrum can be adjusted freely via screws on both sides, perfectly match with different listening space.
Wide frequency range & AGC display: 80Hz-16KHz frequency sweep, high-precision display even can do frequency point test. Speical AGC algorithm and customized output curve, ensure ideal visual effects even the input signal is in a small to large range, avoid that no display when input low and display in full screen when input high.
Many adjustable items & display effects: gain, brighntness, falling speed of main light column, holding time and falling speed of the peak can be adjusted separately. 5 music spectrum display mode and 2 clock display mode, all settings with power-off memory function, no need to set again after restarting.
