Harman Kardon TC300 User Manual

Reproducing dynamic music signals requires high current capability.

Amplifiers can be bridged for increased power into 2 or 4 ohms.

Reproduces frequencies from 10Hz to over 100kHz for accuracy.

Uses high-quality components for stable, low-distortion performance.

Employs separate electronic components for improved linearity.

Exclusive design uses a fan to cool the heat sink, keeping the amp cool.

Fan speed adjusts automatically with music volume for efficient cooling.

Allows reversing fan direction for multi-amp installations to control airflow.
