LEA Professional CS354 4-Channel Power Amplifier, 350W, 70V/110V

LEA Professional CS354 4-Channel 350W Power Amplifier with DSP, Ethernet, IoT-Enabled

Part of LEA Professional’s Internet of Things (IoT) enabled amplifiers, the CS354 is a 350-watt per channel, 4-channel power amp that can output at HiZ (70V or 100V) or LoZ selectable by channel. The amp has 3 ways to connect, use the amp’s built in WiFi access point, connect to the venue’s WiFi, or use the FAST Ethernet to connect to any local area network via the Cat5 or Cat6 cable.

Features

• Web Browser based UI that works on any device with no software to download
• Proprietary Smart Power Bridge allows user to bridge a channel to achieve double the power to that channel without sacrificing and amplifier channel
• Direct LoZ and HiZ (70V or 100V) selectable per channel
• 3 Way to connect: Built-in WiFi access point, Connects to existing WiFi network, Local area network Ethernet connection
• Universal switch mode power supply with PFC. Operates from 100VAC to 24VAC +/- 15%
• 96kHz Analog Devices DSP with input routing, multiple 48dB/octave crossover filters, 8 parametric EQ filters, user configurable speaker limiters, and real-time monitoring
• Fully routable analog inputs
• External I/O port for remote on/off and fault monitoring
• High efficiency Class D output stage for low AC current draw
