1000 WATT SOCL-506 BOARD

Inbuilt speaker protection

Inbuilt vi limiter

Zero dc offset

Symmetrical high-voltage rails (e.g., ±70 VDC) to maximize output swing.

Multiple output transistors (typically paralleled) for high current delivery.

DCO (direct current offset) and bias adjustment provisions—some PCBs include dedicated trimmers to fine-tune thermal balance and reduce hum.

Protection circuits (like speaker protectors) are often included in advanced versions (e.g., SOCL‑504 TEF + protector) elschematic.com.

Large copper traces and thermal management approaches suited for high-power dissipation.
