Equipped with four unbalanced stereo inputs, one balanced stereo output, and a USB input for direct computer audio, the PM4100 makes it easy to manage and distribute sound across a variety of applications. Input 1 can even be mixed with the currently selected input, offering additional versatility in multi-source setups.
Control and connectivity are at the core of the PM4100. Dual RS-232 ports and four GPIO connections allow seamless integration with third-party control systems, relays, and sensors, while network connectivity provides remote management. A built-in 3-band EQ ensures precise tonal adjustment, and auto standby mode improves energy efficiency. The unit is powered via PoE (IEEE 802.3at Class 2, 7W) or 12V DC, with the added benefit of a 12V DC output to power external devices. Reliable, easy to install, and backed by Biamp's five-year warranty, the PM4100 is an ideal solution for meeting rooms, classrooms, and multi-zone commercial audio systems.
