The Lea Professional CONNECT 352 is a 2-channel professional amplifier delivering 350 watts per channel, ideal for small to medium-scale installations. Part of the Network CONNECTSERIES, the world’s first IoT-enabled professional amplifiers, it offers channel-selectable Hi-Z (70V or 100V) or Lo-Z outputs, providing powerful, clear audio for a variety of professional applications.
Cloud and Network Connectivity
The CONNECT 352 connects via three methods: the built-in Wi-Fi Access Point, an existing venue Wi-Fi network, or FAST Ethernet LAN via Cat5 or Cat6 cable. With Cloud connectivity, you can remotely control, monitor, and receive notifications from any device using the Leaprofessional.cloud platform.
