SMART AMP | 4 CHANNELS | 350 WATTS PER CHANNEL

The CONNECTSERIES 354 is a 4-channel amplifier with 350 watts per channel. As part of the Network CONNECTSERIES, the world’s first Internet of Things- (IoT) enabled professional-grade amplifiers, it is perfectly suited for small to medium-scale installations. The 354 features direct HiZ (70V or 100V) or LoZ selectable by channel. With three ways to connect, you can engage the built-in Wi-Fi access point, connect to the venue’s Wi-Fi, or use the FAST Ethernet to connect to any local area network via Cat5 or Cat6 cable.

Then there’s the Cloud…Network CONNECTSERIES is the first professional amplifier family to feature Cloud connectivity. Harness the power of the Cloud for remote control, monitoring, notifications, and more from any of your personal devices. Just connect your amp to a network and start commanding your systems.  Register for your free LEA Cloud account at leaprofessional.cloud

The Network CONNECTSERIES also features analog inputs and external I/O control for remote on/off and fault monitoring.
