LEA Professional LEA CS34 120W 4-Channel Networked Amplifier

Compact Power for Flexible Installations
The LEA Professional CS34 is a 4-channel, 30-watt per channel amplifier built for smaller installations that still demand professional-grade performance. Housed in a compact half-rack enclosure, this network-ready amplifier delivers reliable output at 4, 8, 70V, or 100V—selectable on a per-channel basis. Whether you're powering background music systems or paging zones, the CS34 provides clean, consistent sound with flexible control options that integrate easily into a wide range of AV environments.

Multiple Ways to Connect and Control
The CS34 supports three networking methods to match your installation needs. It can connect through a built-in Wi-Fi access point, join an existing Wi-Fi network, or interface via Ethernet over Cat5/Cat6. This makes system integration quick and simple in venues with different infrastructure constraints. Control is handled through a browser-based interface compatible with any device, so there’s no need for additional software—just plug in and configure.

Cloud-Based Monitoring and Remote Management
Part of the CONNECTSERIES family, the CS34 features secure cloud connectivity for remote management. Once online, users can access the amplifier from anywhere to adjust settings, monitor performance, and receive real-time system notifications. This remote capability is a major asset for AV professionals managing multiple locations, providing responsive troubleshooting and streamlined maintenance.

Smart DSP and Signal Processing Tools
Inside the CS34 is a 96kHz Analog Devices DSP engine that handles critical audio processing tasks. The system includes input routing, 48dB/octave crossover filters, 8-band parametric EQ per channel, speaker limiters, and a routable input matrix—all designed for fine-tuned control over your signal path. It also includes real-time load monitoring and pilot tone detection for added protection and performance insight.

Efficient Class D Performance in a Half-Rack Format
The CS34 utilizes a high-efficiency Class-D output stage, reducing power draw and heat output while maintaining audio integrity. With Smart Power Bridge technology, you can double the output of a single channel without losing any others. Plus, the amplifier runs on a universal power supply with PFC, giving it flexibility for global installations. Its compact footprint makes it ideal for tight spaces in retail, education, or hospitality environments.

Ready for Real-World Applications
From balanced analog inputs with user-selectable sensitivity to external I/O for on/off toggling and fault detection, the CS34 is built to meet the practical demands of system designers and installers. It's quiet enough for noise-sensitive environments, thanks to variable-speed front-to-rear cooling fans, and it’s ready to mount in small enclosures or AV furniture with minimal impact.
