The D 80:4L is a high-power, fully integrated amplifier and signal processor engineered as a central component for large-scale, mission-critical installed sound systems in performing arts centers, broadcast facilities, major houses of worship, and stadiums. Delivering 8000 watts of total system power across four independently flexible channels, it combines formidable Class D amplification with the reference-quality Lake digital signal processing (DSP) platform within a single chassis. This integration allows system designers to actively drive and meticulously control complex loudspeaker systems—from bi-amplified arrays to multi-zone distributed networks—without any external processing hardware. Each channel can be freely assigned, grouped, and processed with a complete suite of tools including linear-phase crossovers, parametric EQ, dynamics control, and precision delay, enabling perfect loudspeaker optimization and alignment directly at the amplifier location.

A defining feature of the D 80:4L is its seamless integration into modern digital audio ecosystems via built-in digital audio networking, typically supporting standards like Dante or AES67. This allows the amplifier to receive multi-channel, low-latency audio directly over an Ethernet network from a central mixing or routing system, dramatically simplifying installation by converging audio, control, and monitoring onto a single cable infrastructure. Comprehensive remote management is facilitated through dedicated software, providing system administrators with real-time access to a vast array of data, including detailed channel metering, thermal performance, load impedance, and system diagnostics, enabling proactive maintenance and remote troubleshooting from any network-connected workstation.

Built for the reliability required in 24/7 continuous operation, the amplifier features robust construction, comprehensive protection circuits, and an adaptive cooling system. Its sonic performance is characterized by the pristine transparency of the Lake processing and the controlled, powerful delivery of its amplification stage, ensuring both high-fidelity music reproduction and exceptional speech intelligibility at any scale. By consolidating network audio transport, studio-grade processing, and high-density amplification into one intelligent unit, the D 80:4L reduces system complexity, increases overall reliability, and offers unparalleled control. It represents a future-proof solution for sophisticated installations where audio quality, system flexibility, and centralized management are non-negotiable requirements.
