LEA Professional LEA CS354-ADSP 4-Channel High-Performance Amplifier

Built for Demanding Installations

The LEA Professional CONNECTSERIES 354-ADSP is a 4-channel, high-performance amplifier delivering 350 watts per channel across a range of output types including 2Ω, 4Ω, 8Ω, 70V, and 100V. Designed for professional-grade installations where accuracy, flexibility, and control are non-negotiable, this amplifier incorporates advanced digital signal processing, Dante connectivity, and IoT-enabled monitoring. Whether you're powering a corporate AV system, a multi-zone venue, or a commercial installation, the CS354-ADSP brings efficient Class-D power and unmatched precision in a compact 1RU form factor.

Precision Audio Tuning with Advanced DSP

Equipped with 96kHz Analog Devices DSP, the CS354-ADSP features linear phase FIR filters with 2048 taps per channel, providing high-resolution crossover management and speaker tuning. It also supports 8-band parametric EQ per channel, output delay of up to 4 seconds, and real-time load monitoring. These capabilities ensure sonic clarity, system protection, and flexible tuning whether you're in a live performance space or a mission-critical conferencing environment. DSP control is accessible via the onboard web UI or remotely through cloud services.

Cloud-Connected for Remote Control and Monitoring

As part of the CONNECTSERIES ADSP line, the CS354-ADSP offers full cloud-based control and monitoring. Simply connect the amplifier to a network using any of three methods—built-in Wi-Fi access point, existing Wi-Fi network, or Ethernet—and gain access to system settings, performance logs, and remote troubleshooting from anywhere in the world. This connectivity model simplifies maintenance for integrators and tech teams managing distributed AV systems.

Versatile Connectivity with Dante Integration

The CS354-ADSP includes primary and secondary Dante ports for seamless integration into networked audio systems. Dante’s low-latency, uncompressed digital audio transmission allows for high channel counts and flexible routing, making this amplifier ideal for larger AV environments and installations with digital signal chains. Fully routable analog inputs also ensure legacy compatibility and system redundancy.

High Efficiency with Flexible Power Management

A universal switch-mode power supply with power factor correction supports global voltage standards from 100 to 240VAC. Smart Power Bridge technology allows you to double the output power to a single channel without giving up another channel, offering additional flexibility when higher wattage is required in specific zones. The high-efficiency Class-D output stage minimizes current draw and keeps operational costs low while maintaining superior audio quality.

Compact and Installer-Friendly Design

Despite its robust features, the CS354-ADSP is housed in a slim 1RU chassis, saving valuable rack space. It includes balanced analog block terminals for easy line and speaker output connection, two removable front air intake filters, and a variable-speed cooling fan for optimal thermal performance. The amplifier is quiet at idle (50dB @ 1m), making it suitable for use in both backroom and in-room AV installations.
