The LEA Professional Connect 354D 350W four-channel Power Amplifier puts an incredible amount of power and connectivity at your fingertips. Packing 350 watts per channel at 4 ohms across its four channels, this innovative amp can drive even the most demanding speaker setups with crystal clarity and robust low end. The Connect 354D utilizes cutting-edge IoT technology, with built-in Wi-Fi and Ethernet allowing you to control and monitor your amp remotely from your smart devices. Audinate's industry-leading Dante digital audio networking system provides lossless digital audio distribution, letting you send high-resolution multi-channel audio between devices with ease.

Harness the Power of the Cloud

The Connect 354D is the first professional power amp to feature cloud connectivity, opening up a world of possibilities. Remotely turn your amp on or off, monitor performance in real time, receive instant notifications if there's an issue—all through the cloud and from anywhere you have an internet connection. Simply connect your amp to a network and you're in full command of your sound system, no matter where you are.

Dante Digital Networking for Flexible I/O

With Dante digital audio networking onboard, the Connect 354D effortlessly integrates into any Dante-enabled audio system. Send up to 32 channels of high-resolution digital audio between Dante devices with no latency or loss in quality. The Connect 354D is also compatible with Dante Domain Manager software for advanced network management and security. Analog and Dante inputs give you the flexibility to connect a variety of sources, while external I/O control allows for remote on/off triggering and fault monitoring from a distance.

Highly Efficient Class D Amplification

At the heart of the Connect 354D is a highly efficient Class D amplifier design that generates minimal heat while delivering maximum power. The result is an ultra-reliable amp that can withstand the demands of continuous use without performance issues. A 32-bit DSP processor with 96kHz sampling provides a pristine signal path, with configurable crossovers, parametric EQs, and output delays on each channel for total system optimization.

Versatile Connectivity for Any Application

With its robust set of features and ample power on tap, the LEA Professional Connect 354D 350W four-channel Power Amplifier is ideal for almost any fixed installation or live sound application. Drive multiple speaker zones, integrate into an existing Dante network, or command your system from anywhere there's an Internet connection—the Connect 354D gives you the flexibility and connectivity to handle it all.
