LEA Professional CS352D – 2-Channel 700W Networked Dante Amplifier
Product Overview
The LEA Professional CS352D is a 2-channel, 700W Class-D commercial-grade rack-mount amplifier with integrated Dante networking, onboard DSP, and IoT-enabled remote management via the LEA Cloud platform. Delivering 350W per channel, the CS352D supports both Low-Z (2, 4, and 8 ohm) and Hi-Z (70V or 100V) distributed audio operation on a per-channel basis, making it a practical choice for small to medium fixed installations that require Dante connectivity in a compact 1U form factor. It is part of LEA Professional's ConnectSeries, the first IoT-enabled professional amplifier line designed for browser-based remote management.
Product Description
The CS352D is built around LEA's proprietary Smart Power Bridge Technology, which allows the two channels to operate in bridged mono mode for a higher single-channel output without permanently dedicating the unit to a single output. Each channel independently switches between Low-Z (2, 4, or 8 ohm) and Hi-Z (70V or 100V), which means a single CS352D can simultaneously drive a direct-impedance loudspeaker on one channel and a distributed 70V ceiling speaker zone on the other.
Network audio connectivity includes dual Dante ports (primary and secondary) supporting AES67 interoperability, an 8x8 Dante channel count at 96kHz or 48kHz, a 100 Mbps Ethernet port for control and monitoring, and built-in Wi-Fi operating in both access-point and local network client modes. The Analog Devices Sigma DSP with a 96kHz, 32-bit core handles EQ, crossovers, signal delay, limiting, and routing. Balanced analog inputs connect via Amphenol Anytek connectors compatible with the LEA XLRF and RCAF-2 adapter cables. The unit draws from a universal SMPS power supply rated 100–240 VAC and cools via front-to-rear variable-speed fans.

Frequently Asked Questions
Q: Can the CS352D run one channel at 70V and the other at 8 ohm simultaneously?
Yes. The CS352D allows each channel to be independently set for Hi-Z (70V or 100V) or Low-Z (2, 4, or 8 ohm) operation. This makes it possible to drive a distributed 70V ceiling speaker circuit on channel one while simultaneously powering a direct-impedance loudspeaker on channel two from the same amplifier.
Q: How does the CS352D connect to a Dante network?
The CS352D includes two physical Dante ports — a primary and a secondary — for connection to a standard Ethernet switch running a Dante audio network. The secondary port can be used for network redundancy. The unit also supports AES67, enabling interoperability with non-Dante AES67-compatible devices. Configuration is done via Dante Controller software on the same network.
Q: Does the CS352D require a dedicated AV control system for remote management?
No. The CS352D connects to the LEA Cloud platform over standard internet connectivity and is managed entirely through a web browser. There is no proprietary control hardware required. It also supports local control via the Ethernet port or Wi-Fi without cloud access if the installation environment does not permit external internet connectivity.
Q: What input connectors does the CS352D use for analog sources?
The CS352D uses Amphenol Anytek balanced 3-pin connectors for its analog inputs. LEA Professional offers two adapter cables: the XLRF (female XLR to Amphenol Anytek) for balanced XLR sources, and the RCAF-2 (female RCA to Amphenol Anytek, 2-pack) for unbalanced RCA sources.
Q: Is the CS352D suitable for a small conference room installation?
Yes. The CS352D is well-suited for small to medium fixed installations including conference rooms, boardrooms, and training rooms. Its 2-channel, 350W-per-channel output handles most commercial loudspeaker systems in those spaces, and its Dante networking allows audio routing from a DSP or media player on the same network without additional analog cabling runs.
