Speaker Protection Module 200 Watt AIYIMA 2.0 Channel Audio Relay - Stereo

Description

AIYIMA 200W 2.0 Channel Speaker Protection Module – Stereo Audio Relay Board provides reliable delay start and DC protection for speakers. It ensures safe amplifier connection, prevents pops during power-on, and protects speakers from damage caused by DC offset or amplifier faults. Fully compatible with Class A, D, and discrete amplifier circuits, including BTL (bridge-tied load) configurations.

The board can be powered either from DC 12V or AC 12–18V, but these inputs are completely independent — do not connect both AC and DC at the same time. The module also includes a fan power connector and a soft-start function, helping to maintain stable amplifier operation and reduce fan noise.

Equipped with a high-quality Songle relay, this board offers low contact resistance, stable operation, and long service life. The design is simple and user-friendly, making installation straightforward even for beginners.

  • Power Supply: AC 12–18V / DC 12V (independent, not simultaneous)
  • Channels: 2 (stereo)
  • Power-on Delay: 3–4 seconds
  • Board Size: 58 × 40 × 27 mm
  • Extra Output: 12V fan or auxiliary power port
  • Features: DC protection, isolated relay control, BTL amplifier support

Perfect for DIY and professional amplifier builds, this module ensures smooth, safe speaker connection without degrading audio quality.
