Small amps range from single-channel models for subwoofers or 70V audio to two- and three-channel models for compact stereo and TV applications, as well as four-channel amplifiers rated at 30 or 60 watts per channel. Depending on the design, an amp may drive low-impedance speakers at 4 or 8 ohms, high-impedance systems at 24V, 70V, or 100V, or offer selectable low- and high-impedance operation.

Small amps may offer analog RCA, optical, microphone, balanced, unbalanced, high-level, or low-level inputs, depending on the amplifier and application. Control and connectivity options can include infrared learning, RS-232, TCP/IP, Bluetooth, Wi-Fi, Ethernet, Dante, AES67, and built-in buttons.

Small amps can be installed behind a display, on a tabletop, on a rack shelf, or inside a structured wiring enclosure when space is limited. In-wall models can fit in a single-gang electrical box, while some compact amplifiers include mounting ears for discreet placement in enclosures or plenum spaces when the installation requirements allow it.

Yes, small amps can support multiroom audio, paging, subwoofers, and networked audio systems, depending on the model’s channels, outputs, impedance options, and control features. Options include multi-channel amplifiers for distributed audio, dedicated subwoofer amplifiers, 70V amplifiers for paging and background music, and network-connected amplifiers with wireless, Ethernet, or Dante connectivity.
