Buerjia NE5532 Dual OP Amplifier Front Audio Stereo Tube Preamp Treble Tone Control Dual Purpose Attenuation Volume Amplifier, Mid-Bass

This machine adopts attenuation tone circuit + NE5532 preamp correction, and the attenuation is -15db when unpowered. When power is applied, the amplification part of the NE5532 works to compensate, with a gain of 0dB, meaning the input and output signals are equal. Try to use a high quality power supply with low ripple for your DC power supply. If the input signal amplitude is less than 1V, a 12V power supply is sufficient. If the input signal exceeds 1V, increase the power supply voltage. The maximum supply voltage is 24V.
