Description

Mono 2-way audio signal input mixing board module NE5532 TDA1308 suitable for microphone voice

 

Graphic details

Using ne5532 or tda138 2-channel mono audio mixer board, made by SMD process. Each audio input has an independent volume potentiometer (SMD adjustable resistor) control. Input 2 mono audio signals at the same time and mix them for output.

Suitable for two mono signal inputs and one output without attenuation. For example, microphone voice audio signals, etc.

Modular design, small size (25mm*20mm)

ne5532 version working voltage: DC 6v-12v

tda1308 version working voltage: DC 3v-6v

PCB size 25mm*20mm (all versions)

Input channel: two mono audio inputs.

Output channel: mono mixed output.

Output amplification: about 1 times

Note: It is recommended to use a linear regulated power supply or battery power supply to avoid interference. Switching power supply needs to pay attention to power supply interference.
