LEA Professional CS164D – 4-Channel Dante Amplifier 160W Per Channel
Product Overview
The LEA Professional CS164D is a 4-channel Dante networked amplifier delivering 160 watts per channel, positioned for commercial AV installations that require a mid-tier power output with full Dante integration and onboard DSP in a 1U rack-mount chassis. Part of the LEA Dante Connect Series, the CS164D combines native Dante audio transport over IP, analog balanced inputs, cloud-based remote management, and an Analog Devices Sigma 96kHz DSP engine in a single unit. It is a practical fit for conference rooms, boardrooms, training facilities, houses of worship, and commercial meeting spaces where Dante-based audio distribution and per-channel output mode flexibility are part of the system design.
Product Description
The CS164D delivers 160 watts across four independent channels, providing a total of 640 watts of system output power in a 1U rack form factor. This power class covers a wide range of commercial speaker loads — including ceiling speakers in distributed audio circuits, near-field conference room speakers, and moderate fill speaker arrays — without the cost or rack space overhead of higher-wattage models. Dante audio transport routes digital audio over Gigabit Ethernet infrastructure, integrating with Dante-enabled sources, DSPs, and other endpoints without point-to-point analog cable runs. Analog balanced inputs are included for non-Dante sources and are fully routable alongside Dante streams through the onboard DSP matrix.
Per-channel output mode selection allows independent configuration of each channel as either constant-voltage HiZ (70V or 100V) or low-impedance LoZ (2Ω, 4Ω, 8Ω), enabling the CS164D to drive both distributed speaker lines and direct-load speakers from the same unit. Network connectivity is available through a built-in Wi-Fi access point, Wi-Fi client mode, or wired Ethernet. LEA Cloud provides internet-based remote monitoring and control via AWS IoT Core without VPN requirements. A browser-based Web UI handles full DSP configuration from any connected device. Smart Power Bridge technology doubles available power on any single channel without taking other channels out of service.

- HiZ / LoZ Per-Channel Selection — Each channel independently selects 70V, 100V, or low-impedance output mode, supporting mixed load types from a single chassis.
- Smart Power Bridge — Doubles output power on any single channel without disabling adjacent channels, providing design headroom for asymmetric zone power requirements.
- 96kHz Analog Devices DSP — Onboard processing includes a fully routable input matrix, 48dB/octave crossover filters, 8-band parametric EQ per channel, speaker limiters, 100ms delay, and real-time load monitoring.
- Three Network Connection Modes — Built-in Wi-Fi access point, Wi-Fi client, and wired Fast Ethernet (Cat5/Cat6) cover all deployment network configurations.
- LEA Cloud Remote Management — Internet-based remote access and fault monitoring via AWS IoT Core; no VPN required for access from any connected device.
- Browser-Based Web UI — Full amplifier configuration from any browser on any device without software installation.
- Universal Switch-Mode Power Supply — PFC-corrected supply accepts 100–240VAC for domestic and international deployment.
- External I/O Port — Remote on/off switching input and amplifier health status output for third-party control system and building management integration.
- Open Third-Party API — TCP and WebSocket API enables integration with Crestron, Extron, Q-SYS, AMX, and other AV control platforms.

Frequently Asked Questions
Q: How does the CS164D compare to the CS84D and CS354D in the Dante Connect lineup?
The CS164D sits between the CS84D (80W/ch, 4-ch) and CS354D (350W/ch, 4-ch) in the Dante Connect Series. All three share the same platform, Dante integration, and DSP architecture. Choose based on per-channel power: CS84D for light loads, CS164D for mid-range commercial speaker applications, CS354D for higher-demand installations.
Q: Can Dante and analog inputs be used simultaneously on the CS164D?
Yes. Both Dante network inputs and analog balanced inputs are active and routable through the onboard DSP matrix simultaneously. Any source — Dante or analog — can be assigned to any output channel, which supports mixed-source system designs where Dante-enabled and legacy analog devices coexist.
Q: Does the CS164D support constant-voltage (70V/100V) speaker systems?
Yes. Each channel is independently selectable for 70V or 100V HiZ operation, making the CS164D suitable for constant-voltage distributed speaker systems common in commercial paging and background music installations. Channels can also be set to LoZ mode simultaneously to drive direct-load loudspeakers alongside distributed circuits.
Q: What DSP processing does the CS164D provide per channel?
Each channel has access to the onboard Analog Devices Sigma 96kHz DSP: a fully routable input matrix, up to 48dB/octave IIR crossover filters (Linkwitz-Riley and Butterworth types), 8-band parametric EQ, user-adjustable peak and RMS voltage limiter, up to 100ms output delay, real-time load monitoring, and pilot tone detection.
Q: How is the CS164D accessed and managed remotely?
Remote management is available through LEA Cloud, which connects over standard internet using AWS IoT Core — no VPN required. The amplifier can also be managed locally via its browser-based Web UI from any device on the same network. Third-party control via TCP or WebSocket API is available for integration with Crestron, Extron, Q-SYS, and similar platforms.
