The LEA Professional Connect 164 is a powerful, network-enabled 4-channel commercial audio amplifier delivering 160 watts per channel for professional sound installations. Designed for small to medium-sized systems, this intelligent Class D amplifier combines flexible speaker compatibility, built-in digital signal processing (DSP), and cloud-based monitoring in a compact 1U rackmount design.
Whether you're installing background music in a restaurant, managing audio across multiple commercial spaces, or upgrading a distributed speaker system, the Connect 164 provides dependable amplification with convenient remote management.
Unlike conventional amplifiers that require on-site adjustments, the Connect 164 supports browser-based configuration and LEA Cloud connectivity, allowing authorized users to monitor amplifier performance, adjust settings, and receive system notifications remotely.

Intelligent Amplification for Commercial Sound Systems
The Connect 164 is designed to simplify professional audio installations that require multiple speaker circuits and dependable system control.
Each of its four amplifier channels can be configured for conventional low-impedance speakers or distributed 70V/100V loudspeaker systems. This flexibility allows installers to support different speaker arrangements without needing separate amplifier types.
The amplifier's integrated DSP provides precise control over signal routing, equalization, crossovers, output delay, and limiting. These features help optimize audio quality while protecting connected loudspeakers.
For businesses with multiple locations or equipment installed in hard-to-access areas, LEA Cloud connectivity makes ongoing monitoring and adjustments more convenient.
