LEA Professional Connect 84 4 Channel Amplifier

Four-Channel Installation Amplifier for Compact Sound Systems

The LEA Professional Connect 84 is a four-channel Class D installation amplifier designed for small to mid-sized commercial audio systems that require efficient power, flexible speaker support, and modern network control. Delivering 80 watts per channel, this amplifier supports both low-impedance and distributed speaker systems, making it well suited for retail spaces, restaurants, offices, classrooms, and background music applications.

Per-Channel Lo-Z and Hi-Z Speaker Compatibility

Each output channel on the Connect 84 can be independently configured for 4 ohm, 8 ohm, 70V, or 100V operation. This per-channel flexibility allows system designers to combine different speaker types within a single installation, reducing the need for additional amplifiers while maintaining consistent performance across multiple zones.

Integrated DSP for Precise Audio Management

An onboard DSP engine provides advanced audio processing tools including crossovers, equalization, routing, and speaker protection. This internal signal processing ensures clean audio distribution, protects connected loudspeakers, and allows installers to fine-tune system performance directly within the amplifier without relying on external processors.

Built-In WiFi and IoT-Based Control

The Connect 84 features built-in WiFi with hotspot capability, allowing direct access from laptops, tablets, or mobile devices using a standard web browser. As an IoT-enabled amplifier, it supports cloud-based monitoring and control, enabling remote configuration, diagnostics, and system management without proprietary software.

Efficient Class D Design for Continuous Operation

Using a high-efficiency Class D output stage, the Connect 84 delivers reliable power while minimizing heat buildup and reducing energy consumption. This design makes it suitable for always-on applications where long-term stability, low operating costs, and quiet operation are critical.

Installation-Ready Connectivity and Control Options

Balanced analog inputs and speaker outputs are provided via secure terminal block connections for dependable performance in fixed installations. External I/O ports allow for remote power control and fault monitoring, making the amplifier easy to integrate into automation systems and centralized AV control environments.
