Product details

The 5W output into 4Ω is the rated continuous power per channel.

Protection features

Built-in short-circuit and thermal protection means the amplifier shuts down before the output stage or speaker is damaged. That's a reliability plus for designs where the load may be intermittent or the enclosure has limited airflow.
