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