The Lectrosonics DM1624 is a sophisticated digital audio processor that functions as an automatic matrix mixer, designed for complex sound reinforcement and conferencing applications in demanding fixed installation environments. This unit provides a highly flexible routing and mixing platform, capable of managing up to 16 discrete input channels and 24 output buses with intelligent, software-controllable signal processing on every path. Its primary application is in council chambers, courtrooms, corporate boardrooms, and similar settings where numerous microphones must be mixed, automixed, and distributed to various destinations such as loudspeaker zones, recording devices, overflow rooms, and broadcast feeds. The processor automates crucial tasks like gating, ducking, and gain sharing, significantly reducing the workload on system operators while ensuring consistent audio clarity and feedback stability.

At the heart of the DM1624 is its powerful DSP engine, which executes advanced algorithms for automatic mixing, ensuring that only active microphones are amplified, thereby reducing comb filtering and improving gain-before-feedback. Each input channel features comprehensive processing including parametric EQ, dynamics control (compressor/limiter/gate), and delay, while each output bus can be independently configured with its own processing and level control. The system's automatic matrix functionality allows any input to be routed to any combination of outputs with adjustable send levels, creating a versatile audio distribution network that can adapt to different room usage scenarios. Control is achieved via intuitive, dedicated PC software that provides a graphical interface for system design, real-time adjustment, and preset recall, allowing integrators to create and save complex configurations for different meeting types or events.

The unit is built for uncompromising reliability in 24/7 operation, housed in a robust 2U rack-mountable chassis with redundant, hot-swappable power supplies. It offers a variety of connectivity options, including analog inputs and outputs on terminal blocks, as well as digital audio interfaces for integration with larger media systems. The DM1624 exemplifies a turnkey approach to complex audio management, providing broadcast-quality audio processing, unparalleled routing flexibility, and automated intelligence that simplifies operation while delivering pristine, intelligible audio across all zones. It is a cornerstone technology for architects and integrators designing integrated AV systems for critical spoken-word environments.
