The LEA Professional CONNECT 352 is a 2-channel professional network amplifier designed for commercial audio, installed sound, and AV applications. Part of LEA Professional's CONNECT Series, the CONNECT 352 combines flexible Lo-Z and Hi-Z output operation, advanced DSP, Dante networking, and remote cloud-based monitoring in a compact 1U amplifier.
Each channel can be configured for low-impedance (Lo-Z) or constant-voltage Hi-Z operation at 70V or 100V, giving system designers flexibility when connecting conventional loudspeakers or distributed commercial speakers.
The CONNECT 352 can be connected to a network using its built-in Wi-Fi access point, an existing venue Wi-Fi network, or Fast Ethernet over Cat5/Cat6 cabling. Once connected, the amplifier can be monitored and controlled remotely through the LEA Professional Cloud platform using a standard web browser.
Advanced DSP and System Control
The CONNECT 352 includes a 96kHz DSP platform with extensive processing and routing capabilities. Installers can route inputs to outputs, configure crossover filters, apply parametric EQ, set speaker limiters, and monitor amplifier load in real time.
The amplifier also incorporates LEA Professional's Smart Power Bridge technology, allowing channels to be bridged without sacrificing an amplifier channel for additional system flexibility.

Network and Cloud Connectivity
The CONNECT 352 is designed for installations where remote system management is important. The amplifier can connect directly to a laptop or mobile device through its built-in Wi-Fi access point, connect to an existing facility network, or use a wired Ethernet connection.
Through the LEA Professional Cloud platform, system operators and installers can remotely monitor amplifier status, make configuration changes, and receive system notifications without needing to be physically next to the amplifier.
This makes the CONNECT 352 particularly useful for installations spread across multiple rooms, buildings, or locations.
Flexible Lo-Z and Hi-Z Operation
One of the major advantages of the CONNECT 352 is the ability to select the output mode independently by channel.
The amplifier supports:
-
8-ohm and other low-impedance applications
-
70V distributed audio
-
100V distributed audio
-
Channel-by-channel output configuration
-
Smart Power Bridge operation
This flexibility allows the same amplifier platform to be used for a variety of commercial sound systems rather than requiring separate amplifier types for low-impedance and constant-voltage applications.
Applications
The LEA Professional CONNECT 352 is a good fit for professional installations such as:
-
Commercial audio systems
-
Retail stores
-
Restaurants and hospitality
-
Corporate facilities
-
Schools and educational facilities
-
Houses of worship
-
Performing arts venues
-
Background music systems
-
Paging and voice reinforcement
-
Distributed 70V/100V speaker systems
-
AV installations
-
Networked audio systems
