The CONNECT 704 is a 4-channel professional amplifier delivering 700 watts per channel, designed for small to medium-scale installations. Part of the Network CONNECTSERIES, the world’s first IoT-enabled professional amplifiers, the 704 offers channel-selectable Hi-Z (70V or 100V) or Lo-Z outputs, providing maximum flexibility for any installation.
Advanced Network and Cloud Connectivity
Connect your amplifier via three options: 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, the CONNECT 704 allows remote control, monitoring, notifications, and system management from any device via the Leaprofessional.cloud platform.
