LEA Professional CS354D-G ConnectSeries 1400W 4-Channel Networked Amplifier (Government Model)
Ideal for sound installations in small- or medium-sized spaces, the CS354D-G from LEA Professional is a 4-channel, 1400W class-D power amplifier, capable of delivering 350W per channel, and supporting impedance loads of 2, 4, or 8 ohms as well as 70 or 100V Hi-Z output loads per channel. Designed for fast and easy network control, the CS354D-G sports a 100 mb/s Ethernet input port and two Dante inputs (primary and secondary) for connecting to external control devices, including web- and IoT-based cloud services as well as an analog input for direct remote I/O control.

The CS354D-G features balanced, analog Amphenol Anytek block terminal I/O for line inputs and speaker outputs. The Smart Power Bridge technology lets you dynamically double power on each channel when needed without sacrificing the power quality on other channels, and with 32-bit / 96 kHz DSP processing, you are assured clean, clear audio distribution with minimal latency. This amp includes all necessary block terminal cables for each input and output, two removable and washable foam filters for the front air intake, and one IEC power cable to get you started right away.
This is the special government model, which excludes Wi-Fi support for secure operation.
