Description
Compact, Powerful Amplification for Any Zone
The Russound A2100 is a space-saving half-rack Class D amplifier built to add high-quality, high-powered stereo amplification wherever a system needs it, whether that's extra power for a demanding pair of speakers or an additional zone in a larger room or outdoor area. Its half-rack design combines easily with other Russound half-rack products, and it's genuinely installer-friendly, with a 12V trigger for automated turn-on, a buffered line output for expanding to additional amplifiers, and a cable lock to prevent accidental disconnects during servicing.
