Avoid generic PDF aggregators that require email sign-ups or offer binary blobs instead of PDFs.
: Delivers up to 100W + 100W RMS into a standard load at low Total Harmonic Distortion (THD). Total Harmonic Distortion (THD) : Rated at 0.8% maximum ( at rated power). Maximum High-Rail Voltage ( VCHcap V sub cap C cap H end-sub max) : (dependent on the specific sub-series variant). Maximum Low-Rail Voltage ( VCLcap V sub cap C cap L end-sub max) : (dependent on the specific sub-series variant). Load Impedance ( RLcap R sub cap L ) : Optimally rated for speakers .
The STK412-230 does not feature built-in DC offset protection for speakers. If an internal transistor fails, raw DC voltage can pass directly to your speakers and destroy them. Always pair the module with an external protection circuit (such as one based on the UPC1237 IC) utilizing a mechanical relay. Heatsink Requirements
The STK412-230 stands out due to its technology, which dynamically switches the supply voltage based on the input signal level to maximize efficiency and reduce heat. Output Power : Delivers up to Amplifier Class : Class H (High efficiency). Total Harmonic Distortion (THD) : Typically rated output. Operating Voltage : Recommended range often falls between ±70Vplus or minus 70 cap V ±90Vplus or minus 90 cap V
