Stk412530 Datasheet

: Operates on a dual power supply, generally ranging from ±20V to ±35V . Configuration : Two-channel (stereo) amplification.

Operating beyond these maximum metrics can instantly puncture the internal power transistors: : Maximum Supply Voltage 2 (Signal Present, ) : Maximum Supply Voltage 3 (Signal Present, ) : Substrate Operating Temperature : 125∘C125 raised to the composed with power C Storage Temperature Range : -30∘Cnegative 30 raised to the composed with power C +125∘Cpositive 125 raised to the composed with power C 3. Recommended Operational Conditions

Always use a bulb current limiter (DBT) when testing these modules. A shorted STK will take out your power supply transistors, rectifier diodes, and speakers faster than you can hit the power switch. stk412530 datasheet

Requires a bipolar (dual) power supply, often around ±30V to ±40V (VL) and ±57V (VH) for full power operation. Maximum Supply Voltage: Up to ±69V (no signal). : Operates on a dual power supply, generally

It is designed to minimize total harmonic distortion (THD), preserving signal integrity and providing high-fidelity, crystal-clear sound across its full power bandwidth.

: Up to 150W + 150W (300 Watts total). Recommended Speaker Impedance : Optimally handles 6 Ωcap omega Ωcap omega loads . Total Harmonic Distortion (THD) : Typically at nominal rated power outputs. 2. Absolute Maximum Ratings Recommended Operational Conditions Always use a bulb current
