Sound Operational Preamplifier Board, 5X Dual Channel Digital Tone Board DC1230V Power Supply Input NE5532 Amplifier Front Panel

Description

• CLEARER SOUND: Sound operational preamplifier board uses the original imported op amp chip, compared to similar op amp sound more pure bottom noise is smaller.
• SOUND PREAMP: Digital tone board needs to be connected to the amplifier at the sound output end, and then the amplifier will be connected to the speaker to have sound.
• WIDE VOLTAGE INPUT: NE5532 amplifier front panel is suitable for all sound amplifier preamp source amplification. Wide voltage input, the input voltage is DC1230V.
• NOTE: Connect DC1230V power supply at the power input of the amplifier board, pay attention to distinguish between positive and negative, VCC is positive.
• PCB MATERIAL: Sound operational preamplifier board module is made of PCB material, which is and not easy to damage. Widely applicable, easy to use.
