AU-10X 8C 12C立体声音频前置放大器 Stereo audio preamplifier

耳听为王2024-03-13产品说明书251

  本机为立体声音频前置放大器,有些数码产品输出音频幅度较小,经过本机放大接入功放、有源音箱等其他音频设备,使其可以满功率输出;

  AU-10X外接12V电源适配器供电,由NE5532发烧经典运放芯片组成的10倍(20db)前置放大电路,可以当做耳机放大器,输出可接功放音响等音频设备; 

  AU-8C,放大增益8倍(18db),内置锂电,充一次电可以连续工作40-50小时左右,输出不能接耳机,可以接音响功放等音频设备;

  AU-12C,放大12倍(21.6db),内置锂电,充一次电使用约8-10小时,可驱动耳机,音响功放等音频设备;

充电指示灯状态:连续闪4下表示4格电量,3下表示3格,以此类推,充满电长亮。

充电可使用自己的手机充电头,请尽量不要边充边用,会产生干扰杂音

接口与旋钮功能如下:

1、ROWER电源开关;

2、VOLUME音量大小调节;

3、PHONES耳机接口

4、IN为音频输入接口,莲花与3.5两种接口,可接MP3、手机、CD、电脑等音频播放设备.........

5、OUT为输出,莲花与3.5两种接口,接有源音响或者功放的输入;(以上两种接口是为了方便适用不同的场合,根据需要选择其一即可。)

注意,请根据自己的音响功率调整到适当的音量,使其声音大不失真为最佳,胡乱加大只会适得其反!!


This device is a stereo audio preamplifier. The audio output amplitude of some digital products is relatively small. After being amplified by this device and then connected to other audio equipment such as power amplifiers and active speakers, they can output at full power.
The AU-10X is powered by an external 12V power adapter. Its preamplification circuit, which is composed of the NE5532 high-fidelity classic operational amplifier chip and has a 10-fold (20dB) amplification, can be used as a headphone amplifier. The output can be connected to audio equipment such as power amplifiers and speakers.
The AU-8C has an amplification gain of 8 times (18dB). It has a built-in lithium battery and can work continuously for about 40 to 50 hours on a single charge. Its output cannot be connected to headphones but can be connected to audio equipment such as speakers and power amplifiers.
The AU-12C has an amplification of 12 times (21.6dB). It also has a built-in lithium battery and can be used for about 8 to 10 hours on a single charge. It can drive headphones, speakers, power amplifiers and other audio equipment.
Status of the charging indicator: Flashing continuously 4 times indicates 4 bars of battery power, 3 times indicates 3 bars, and so on. When fully charged, it stays on.
You can use your own mobile phone charger for charging. Please try not to use it while charging as it may cause interference and noise.
The functions of the interfaces and knobs are as follows:
ROWER: Power switch.
VOLUME: Knob for adjusting the volume.
PHONES: Headphone interface.
IN: Audio input interface. There are two types of interfaces, RCA and 3.5mm, which can be connected to audio playback devices such as MP3 players, mobile phones, CDs, and computers.
OUT:  There are also two types of interfaces, RCA and 3.5mm, which are used to connect to the input of active speakers or power amplifiers. (The above two types of interfaces are provided for convenience in different situations. You can choose either one according to your needs.)
Note: Please adjust the volume to an appropriate level according to the power of your own speakers. The best situation is to make the sound loud without distortion. Increasing the volume randomly will only be counterproductive!!!
