Model name: XR-1S, XR-4S, KAC-X1D, KAC-X4D

High output causes the internal temperature of an amplifier to rapidly increase, often triggering protection circuits. Conventional protection measures shut down the amplifier to prevent damage, but Kenwood’s Thermal Management System maintains operation, while in the background it detects and suppresses the temperature increase, successfully providing uninterrupted listening enjoyment and extending the lifetime of internal components!!

By positioning the fan in close proximity to heat producing circuitry, heat is dissipated in a timely manner. This allows the amplifier to operate at comfortable temperature levels even under the most stressful conditions.
