Lorenz Class-D Power Amplifier
LZV200DF
Overview:
The Lorenz Class-D Power Amplifier is engineered to deliver exceptional sound clarity, high efficiency, and long-term reliability in professional audio installations. Packaged in a compact ½-rack form factor, it is ideal for integration into space-constrained environments without compromising performance. The amplifier is designed for mission-critical applications such as conference rooms, training centers, auditoriums, command & control facilities, and high end AV infrastructures.
Features:
- Compact Professional Design – High-performance Class-D amplification in a space-saving ½ rack chassis, ideal for flexible system integration.
- Scalable Options – Available in both 2-channel and 4-channel models with selectable power supply capacities to suit diverse applications.
- State-of-the-Art DSP – Integrated DSP for precise system tuning, protection, and performance optimization.
- Flexible Connectivity – Multiple analog input options across all models, with line-level outputs provided in the 2-channel versions.
- Audio Networking – AL+ Models: AES67 audio networking support.
- AD(L) Models: Dual-protocol compatibility with AES67 and Dante™ AoIP, powered by an integrated Gigabit Ethernet switch with daisy-chain capability for seamless networked audio.
- Discreet Installation – Compact sealed versions are certified for hidden placements, including ceiling mounts and in-wall enclosures.
- Versatile Mounting – Supplied accessories allow mounting of one or two amplifiers in a 19” rack, a single unit in an 11” rack, or directly onto any surface (wall, ceiling, or under-table). Rubber feet also enable shelf placement.
- Auto Setup Function – A single-button configuration automatically calibrates gain, limiters, and high-pass filters based on connected loudspeakers, ensuring optimum performance with minimal effort.
- Power Sharing Technology – Each channel intelligently shares headroom, allowing up to the full rated output of the power supply in the 320W models, and proportionately high delivery in the 600W series.
- Applications – Perfect for conference rooms, training centers, classrooms, and distributed audio systems, the Lorenz Class-D Power Amplifier guarantees professional sound reinforcement with energy efficiency, flexibility, and long-term reliability.
