Product Overview
LEA Professional CS704D 4-Channel 700W Dante Power Amp with DSP, Ethernet, IoT-enabled
Part of LEA Professional’s Internet of Things (IoT) enabled amplifiers, the CS704D is a 700-watt per channel, 4-channel power amp with Dante® 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%
