B022 Pre-Stereo Signal Amplifier Volume Booster Headphones Active Speaker Preamp Audio Amplifier

Product presentation:
You have a playback device output signal source such as (TV audio, player, video game, cell phone, tablet, computer, jukebox, etc.) just not loud enough / volume loud enough?
A powerful front stereo signal amplifier sound enhancer can solve the problem of low sound.
1. Sound amplification using Japans original imported 4580 chip for amplification. Volume boost and bottom noise is small, dynamic range will not produce explosive sound.
2. Amplified output gain in the original input signal source based on +60DB, suitable for general output level signal sound small equipment.
3. Input using 2 groups of stereo input, 3.5mm and RCA two kinds of interface input, can be mixed at the same time.
4. The output has three groups of stereo output, the front end has two groups of 3.5mm and 6.35mm headphone port output. The back end has a group of RCA output, 3 groups of interface output at the same time.
5. The output has 2 groups of independent volume adjustment, 1 volume adjustment to adjust the 3.5mm and 6.35mm output. 1 volume adjustment to adjust the RCA output.
6. Headphone interface output can drive 16 ohms-600 ohms headphones
7. Power supply using 220V to AC9V AC transformer power supply, sound amplification is strong and powerful
