he CS64 is a 4-channel professional amplifier delivering 60 watts per channel in a compact ½ rack space form factor, perfect for small to medium-scale installations. Part of the Network CONNECTSERIES, the world’s first IoT-enabled professional amplifiers, the CS64 offers channel-selectable Hi-Z (70V or 100V) or Lo-Z outputs, giving maximum flexibility for any installation.

Flexible Network Connectivity
Connect the CS64 using three options: the built-in Wi-Fi Access Point, the venue’s existing Wi-Fi network, or FAST Ethernet LAN via Cat5 or Cat6 cable. With Cloud connectivity, the CS64 allows remote control, monitoring, and notifications from any personal device using the Leaprofessional.cloud platform, enabling effortless system management.
