Choose a 3-channel amplifier with a per-channel power rating that matches your speakers’ requirements at their impedance, while accounting for speaker sensitivity, room size, and desired listening level. Lower output may suit TV audio or smaller rooms, while larger spaces or higher volume levels may call for more power.

When integrating a 3-channel amplifier with existing AV equipment, confirm that its input connections match your source and that its channel and power capabilities suit the speakers and room. Also check the speaker load, installation space and ventilation, and any control or network requirements for the system.

Compact 3-channel amplifiers suit space-conscious installations, including adding audio to a TV without a bulky AV receiver, while higher-power models provide greater output capacity for systems that need more amplification. Compare available space, speaker requirements, and system needs, and check whether features such as PoE++ power, DSP configuration, or built-in streaming fit the installation.

Compare the amplifier’s wattage per channel with the power needs of the speakers and the room. Check which source and speaker connections it provides, and whether you need options such as PoE++ power or MoIP streaming.
