LEA Professional 164D Overview
Ideal for sound installations in small- to moderate-sized spaces, the CS164D from LEA Professional is a 4-channel, 640W Class-D power amplifier, capable of delivering 160W 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 easy network control, the CS164D sports three methods of network connection: 100 MB/s Ethernet input port, two Dante ports (primary and secondary), and built-in Wi-Fi with both access-point and local Wi-Fi support. These allow you to easily connect to external control devices including web- and (internet-of-things) IoT-based cloud services. Plus, you get an analog input for direct remote I/O control.
The CS164D 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.
