Description
Theory Audio Design PLC-9K4 - 4-channel speaker controller with Dante/AES67
The Theory Audio Design PLC-9K4 is a professional 4-channel speaker controller with a built-in amplifier, designed for the most demanding AV installations, object sound systems, sports facilities, performance halls, conference centers, and large commercial spaces. The device combines very high output power, advanced DSP processing, and native support for Dante and AES67 networks, enabling the implementation of complex audio systems based on Audio over IP technology.
The PLC-9K4 model delivers a total of 9000W of power in a compact 1U rack enclosure, providing exceptionally high performance with minimal space requirements in the installation rack. Four amplifier channels support both low-impedance systems and high-voltage installations of 70V and 100V, offering great flexibility in designing professional sound systems.
The device is equipped with three configurable Gigabit Ethernet ports, including one PoE port. Each port can operate in audio transmission mode, control mode, or both functions simultaneously. Integration with Powersoft Armonia+ software allows for quick design, configuration, and commissioning of audio systems, while the Powersoft MyUniverso platform enables remote monitoring and management of the device in real-time.
An advanced 48kHz/24-bit DSP processor provides full control over system parameters. Available features include parametric equalization, FIR and IIR filters, active crossovers, delay adjustments, polarity management, and advanced limiters. Dedicated presets for all Theory Audio Design speaker models allow for quick system deployment and optimal performance of speaker sets.
