Biamp Tesira AMP-4300R CV
Four-Channel 300W Networked AVB Constant-Voltage Amplifier
The Tesira AMP-4300R CV is a networked constant-voltage amplifier built for distributed audio across large spaces. Each of its four channels delivers 300 watts to 70V and 100V loudspeaker lines, the standard approach for driving many speakers over long cable runs in paging, background music, and life-safety-adjacent applications. Audio arrives over the Tesira AVB network, so zone routing and levels are managed centrally in software.
Integrated digital signal processing at the amplifier supports line tuning, limiting, and monitoring to keep distributed zones consistent and protected. As part of the Tesira platform, it reduces analog cabling between the head end and amplification while giving designers scalable, networked control of constant-voltage loudspeaker systems throughout a facility.
