Biamp Tesira AMP-D225H 2-Channel Dante PoE+ Amplifier 25W/50W

The Biamp Tesira AMP-D225H is a high-performance, two-channel PoE+ amplifier designed for professional audio installations. Part of the Tesira family, it delivers 2x 25W at 8Ω or 2x 50W at 4Ω/70V/100V, with full Dante network audio (2x2 channels). Its fanless, convection-cooled design ensures silent operation in plenum spaces, while the integrated Tesira DSP suite provides EQ, dynamics, mixing, and routing. Ideal for commercial AV, conferencing, and distributed audio systems.

Advantages

Power over Ethernet (PoE+) eliminates the need for separate AC power, simplifying installation. The amplifier supports both low-impedance (4/8Ω) and high-impedance (70V/100V) loads, offering flexibility for various speaker types. Full Dante audio networking enables seamless integration with digital audio systems. The fanless design ensures silent operation, making it suitable for noise-sensitive environments like classrooms, boardrooms, and houses of worship.
