LEA Professional CS84D – 4-Channel Dante Amplifier 80W Per Channel

Product Overview

The LEA Professional CS84D is a 4-channel Dante networked amplifier delivering 80 watts per channel, designed for commercial AV installations requiring compact distributed audio amplification with full IP network connectivity. Part of the LEA Dante Connect Series, the CS84D combines Dante audio transport, analog balanced inputs, an onboard 96kHz DSP, and LEA Cloud management in a 1U rack-mount chassis. It is particularly well suited for conference rooms, boardrooms, training rooms, and commercial meeting spaces where lower speaker loads and multi-zone paging or background audio require a compact, network-managed amplifier. Each channel independently selects HiZ (70V/100V) or LoZ output mode, giving integrators load flexibility within a single unit.

Product Description

The CS84D provides four independent 80-watt amplifier channels in a standard 1U rack-mount enclosure, addressing installations where moderate power output and Dante connectivity are both required without committing to a larger chassis. Dante audio transport routes digital audio over standard Gigabit Ethernet alongside control and monitoring data, reducing cabling infrastructure in facilities that already use or plan to deploy Dante. Analog balanced inputs are included and fully routable through the DSP matrix, providing signal flexibility for sources outside the Dante network. Per-channel output mode selection allows the CS84D to drive both 70V/100V constant-voltage speaker circuits and low-impedance loads from the same unit.

System connectivity options include a built-in Wi-Fi access point for direct device management, integration into an existing venue Wi-Fi network, or wired Fast Ethernet via Cat5/Cat6. A browser-based Web UI provides full amplifier configuration from any device without software installation. LEA Cloud extends access globally over standard internet connections using AWS IoT Core, without requiring a VPN. The onboard Analog Devices Sigma 96kHz DSP processes crossover filtering, 8-band parametric EQ, speaker limiting, input routing, output delay, and real-time load monitoring per channel. Smart Power Bridge allows any single channel to deliver doubled output power without disabling adjacent channels.

Key Features

• Dante Audio Transport — Native Dante connectivity routes audio over Gigabit Ethernet, integrating directly into Dante-enabled AV systems without added analog cabling infrastructure.
• 4 Channels at 80W Each — Compact power output suited for conference rooms, breakout spaces, and distributed paging zones where speaker loads are modest.
• HiZ / LoZ Per-Channel Selection — Each channel independently selects between 70V, 100V constant-voltage and low-impedance operation, allowing mixed load types within one chassis.
• Smart Power Bridge — Any channel can be bridged for doubled power without taking other channels offline, providing headroom when one zone requires more output than the default configuration.
• 96kHz Analog Devices DSP — Full onboard DSP handles input routing matrix, 48dB/octave crossover filters, 8-band parametric EQ per channel, limiter, output delay, and real-time load monitoring.
• Three Network Connection Modes — Built-in Wi-Fi AP, Wi-Fi client, and wired Fast Ethernet (Cat5/Cat6) support flexible deployment in any venue network environment.
• LEA Cloud Management — Remote monitoring, control, and fault alerts via AWS IoT Core, accessible from any device over standard internet without VPN.
• Browser-Based Web UI — All configuration is accessible from any browser on any device; no proprietary software or dedicated control hardware required.
• Universal Power Supply — Switch-mode supply with Power Factor Correction accepts 100–240VAC for domestic and international use.
• External I/O Port — Remote on/off input and fault status output for integration with third-party control and building management systems.

Typical Applications
