How do we rank
Our AI-powered platform ranks products using multiple weighted factors from millions of products and user reviews across the web, providing the most valuable and real data. Higher scores rank first.
The chip has high conversion rate and strong drive ability, which will greatly help your project
Small clutter interference of power grid, stable and performance
Power supply circuit adopts full bridge rectifier, the four pins of rectifier is respectively in parallel connected with decoupling capacitor, effectively eliminate the high frequency interference of AC power grid
WIDELY COMPATIBLE WITH ALL AUDIO DEVICES: Inputs fit DVDs, CDs, set top boxes, MP3s, TVs, cell phones, computers, tablets, turntables, sound cards, guitars, basses, electronic musical instruments, game consoles or other devices. Output suitable for speakers, subwoofers, Sound Blasters, reverbs, AV receivers, post amps, headphones, etc.
LOW POWER CONSUMPTION: The DC power supply should try to use a excellent low power supply. When the input amplitude is less than 1v, 12v power supply is sufficient. When the input is greater than 1v, please increase the power supply voltage, the maximum power supply voltage is 24v
EASY SETUP: No special software, apps or drivers needed to install, a true plug and play digital audio adapter
STRONG DRIVE ABILITY: Includes 10X preamp tone board as well as treble, mediant, bass and volume control. Chip has high conversion rate and strong drive ability.
SMALL NOISE: Preamplifier tone board has reasonable circuit board layout, small noise, beautiful component layout. Better performance,noise is very small.
POWER: Volume control amplifier board with op amp IC socket, convenient to upgrade for flexible use. AC 12V-18V power supply voltage.
SAME INPUT AND OUTPUT: This machine adopts the circuit pre attenuation compensation and tone NE5532, when the power is off, the attenuation is ‑15db, when the power is on, the NE5532 amplifies the compensation, and the gain is 0db, that is, the input and output are the same
