TV sound channel with 1-watt output using an ECG807. The circuit features DC volume control with 70 dB attenuation typical, limiter gain of 70 dB, limiting threshold at 200 μV, automatic thermal shutdown, and audio output short-circuit protection. The circuit will drive 8-, 16- or 32 -ohm speaker loads and provide a true 1-watt output with an 8-ohm load (courtesy GTE Sylvania Incorporated).
