The AMP-450P is a four-channel PoE+ (IEEE 802.3at Class 4, 30W) conferencing amplifier for use in Tesira® systems. The output channels are software configurable, including selectable power versus channel count. PoE+ power allows the AMP-450P to be placed wherever you need it. Suitable for air handling spaces, the amplifier can be located close to ceiling speakers if desired. The AMP-450P includes an internal limiter, and is capable of providing 3 watts of continuous power to all four channels. The Tesira AMP-450P is also capable of operating in a burst mode to handle peak signals, providing up to 50 watts (4Ω load) or 30 watts (8Ω load) per channel. The amplifier serves as a dedicated endpoint in a Tesira system, making installations easier to design, support, and maintain. The AMP-450P is ideal for TesiraFORTÉ®-equipped conference rooms or other applications where sound reinforcement is needed.
