The VX-3000PM is a preamplifier matrix panel engineered for integration within TOA’s VX-3000 Series voice alarm and public address systems. Designed to expand input and control capabilities, the VX-3000PM connects directly to a VX-3000 Frame via a network, enhancing the system’s overall flexibility and scale. It features eight audio input channels, each with individual volume control, enabling the accommodation of multiple audio sources such as microphones and external devices. In addition, it offers 20 control inputs and 10 control outputs, supporting diverse configuration requirements for system control and monitoring. The VX-3000PM plays a critical role in environments requiring distributed audio management, such as commercial buildings, transportation hubs, educational institutions, and industrial facilities. With support for unicast audio transmission between VX-3000PM units, the panel facilitates decentralised broadcast control and remote microphone announcements across multiple zones. A single VX-3000PM can be connected to each VX-3000 Frame, and systems can be configured with up to 40 panels, allowing for substantial system expansion. The 1U rack-mountable form factor ensures compatibility with standard EIA equipment racks, providing convenient and space-efficient installation. The VX-3000PM is a vital component for systems where reliable audio distribution and operational control are essential to daily communication and emergency response functions.
