- Materials: high-grade pure black immersion gold circuit board, WIMA red sound capacitor, large capacity filter capacitor. Special customized pure black copper terminals, gold-plated audio input terminals.
- Protective Functions: input reverse connection protection, short-circuit protection, over-current protection, over-heat protection, over-voltage protection, low-voltage protection, EMI is allowed to pass.
(3) Other Functions:
External mute function (MUTE: high level mute, factory default low level)
External turn-off function (SD: low-level chip turn off, factory default high level)
To use the mute/sd function, just remove the resistance next to the MUTE welding spot and add a switch between the welding spot under the resistance and the welding spot next to MUTE/SD.
