TO-10立体声无源衰减式音调控制器 passive Attenuated tone controller

耳听为王2024-03-20产品说明书676

  本机采用衰减式音调电路+NE5532前置放大补偿,不供电时衰减量为-15db,供电时NE5532放大部分工作进行补偿,增益为0db,即输入输出信号相等。

输入阻抗:600欧,输出阻抗无源时100K,有源时600欧;

低音转折频率450HZ,高音转折频率2.2KHZ,最大提升衰减量15db。


接口及旋钮说明:

VOLUME:音量大小;

TREBLE:高音调节,中间12点位置为初始值,逆时针位衰减,顺时针为提升;

BASS:低音调节,中间12点位置为初始值,逆时针位衰减,顺时针为提升,

白色按键开关:不供电时弹起,总音量减小-15db,供电时按下,总音量保持原始值0db,即输入输出相等;

IN输入,3.5/莲花两种接口,接音源等播放设备;

OUT输出,3.5/莲花两种接口,接音响功放等音频设备,设计两种接口的目的是为了适应不同的场合方便使用,根据实际情况任选其一即可;

供电:直流12V-24V之间,功耗:0.1W,接口规格5.5*2.1内正外负,直流供电请用低纹波优质电源。


This device adopts a passive attenuated tone circuit + NE5532 operational amplifier pre-amplification circuit. When there is no power supply, the attenuation is -15dB; when powered, the NE5532 pre-amplification part works for compensation with a gain of 0dB, meaning the input and output signals are equal.

Input impedance: 600 ohms;

Output impedance: 100K ohms in passive mode, 600 ohms in active mode;

Bass turnover frequency: 450Hz;

Treble break frequency: 2.2KHz;

Maximum boost and attenuation: 15dB.

White key switch: In the OFF passive state, the total volume is reduced by -15dB; when powered, pressing it keeps the total volume at the original value of 0dB, meaning the input and output are equal.

Supply voltage: DC12V-24V

Power consumption: 0.1W
