Description

Overview

Introducing the world’s first Internet of Things- (IoT) enabled, professional-grade amplifier family – the NETWORK CONNECTSERIES. Perfectly suited for small to medium scale installations, these two, four, and eight channel amps feature 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.
