Integra ADM-20.4 2-Channel Power Amplifier

Overview

The Integra ADM-20.4 is a two-channel power amplifier designed to deliver clean, reliable stereo drive. It is rated at 75W per channel into 8 ohms and 65W per channel into 4 ohms (both channels driven, FTC), with a wide 10Hz-100kHz frequency response and a strong 110dB signal-to-noise ratio.

Why This Model Matters

Compact and integration-friendly, the ADM-20.4 adds dedicated stereo power to a system without the bulk of a large chassis. A 12V trigger input and output with audio switching make it easy to automate and chain into control-driven installs, while its low 0.08% THD keeps the sound clean across the range.
