W-10P立体声无源音量控制器 Stereo passive volume controller

本机特点：

1 、采用优质电位器；

2 、无源器件不影响音质； 

3 、总音量调整，双声道左右平衡调整；

接口及旋钮功能：

1、输入输出有双声道3.5mm插座，莲花插座， L为左声道， R为右声道；

2、IN：输入接口， 接音源， MP3 、手机、电脑、声卡、电声乐器等音频播放设备;

3、OUT输出接口： 接音响，功放等其他音频设备；

作用：接在音源与前级之间或者前级与功放之间，串在音频回路里控制音量大小。

平衡旋钮是调节左右声道的音量，由于是无源电路条件限制，平衡调节只有在主音量旋钮80%以下调节曲线比较平滑。

特别提醒这不是放大器，本机只能在原有的基础上减小音量;

也不是控制喇叭的，喇叭端是功率输出无法调节的。

W-22，基本功能接口同上，左右声道可分别调整。 

W-12，耳机音量控制器，左右声道音量分别调节，机上有3.5mm，6.5mm两种接口，适合听感偏音的人群使用。

Features of this device:

High-quality potentiometers are adopted.

Passive components do not affect the sound quality.

Total volume adjustment and left-right balance adjustment for the dual channels.

Functions of the interfaces and knobs:

For input and output, there are dual-channel 3.5mm sockets and RCA sockets. L represents the left channel, and R represents the right channel.

IN: Input interface, which is connected to audio sources such as MP3 players, mobile phones, computers, sound cards, electro-acoustic musical instruments and other audio playback devices.

OUT output interface: Connected to active speakers, power amplifiers and other audio devices.

Function: Connected between the audio source and the preamplifier or between the preamplifier and the power amplifier, and connected in series in the audio loop to control the volume level.

The balance knob is used to adjust the volume of the left and right channels. Due to the limitations of the passive circuit conditions, the balance adjustment curve is relatively smooth only when the main volume knob is adjusted below 80%.

Special reminder: This is not an amplifier. This device can only reduce the volume on the original basis.

It is also not used to control the speaker, as the speaker is a power output and cannot be adjusted.

For W-22, the basic functional interfaces are the same as above, and the left and right channels can be adjusted separately.

For W-12, it is a headphone volume controller. The volume of the left and right channels can be adjusted separately. There are two types
