功能介绍：

【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 Japan's 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 16Ω-600Ω headphones

7, power supply using 220V to AC9V AC transformer power supply, sound amplification is strong and powerful

产品中文标题：前置立体声信号放大器 音量增强器 耳机 有源音箱前级音频放大器

产品功能介绍：

你有一个播放设备输出信号源如（电视音频，播放器，视频游戏，手机，平板，电脑，唱机等）只是声音不够响亮/音量不够大声？

一个强大的前置立体声信号放大声音增强器可以解决声音小声的问题。

1、声音放大采用日本原装进口4580芯片进行放大，音量提升大和底噪小，动态范围大不会产生爆音。

2、放大后输出增益在原输入信号源基础上+60DB，适合一般输出电平信号声音小的设备。

3、输入采用2组立体声输入，3.5mm和RCA二种接口输入，可以同时混合输入。

4、输出有3组立体声输出，前端有2组3.5mm和6.35mm耳机口输出，后端有RCA一组输出，3组接口同时输出

5、输出有2组独立音量调节，1个音量调节调3.5mm和6.35mm输出，1个音量调节调RCA输出，

6、耳机接口输出可以驱动16Ω-600Ω的耳机

7、电源采用220V转AC9V交流变压器供电，声音放大强劲有力
