Introducing the Connect 1504, a professional-grade, IoT-enabled smart amplifier designed for unmatched power, flexibility, and remote control. With 1,500 watts per channel, this four-channel amplifier delivers pristine audio performance across 2, 4, and 8-ohm loads, as well as 70V and 100V high-impedance systems, making it ideal for commercial, installation, and live sound applications.

Seamless Network Connectivity
The Connect 1504 offers three network connection options: connect via the built-in Wi-Fi Access Point, join an existing Wi-Fi network, or use a wired Ethernet LAN connection. Take advantage of Cloud connectivity—the first in professional amplifiers—to remotely control, monitor, and receive notifications from any device using the Leaprofessional.cloud platform.
