The 354 4-channel 350 watt power amplifier is part of the Internet of Things- (IoT) enabled, professional-grade amplifier NETWORK CONNECTSERIES. Perfectly suited for small to medium scale installations, this four channel amp 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. Cloud connectivity is a popular feature. 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.
