Description
The LEA Professional CONNECT 3004 is a high-power, four-channel professional smart amplifier designed for large-scale audio installations. Delivering 3,000 watts per channel at 2Ω, 4Ω, 8Ω, 25V, and 70V/100V, it supports both low-impedance loudspeakers and high-impedance distributed audio systems. Each channel can be configured independently for low-impedance or 70V/100V operation, providing flexibility for demanding commercial sound reinforcement and multi-zone installations.
The CONNECT 3004 combines a highly efficient Class-D output stage with proprietary Smart Power Bridge technology and a 96kHz Analog Devices SHARC DSP processor featuring a 32-bit core and sample rate converters. Its advanced processing includes linear-phase FIR crossovers, IIR filters up to 48dB per octave, eight-band parametric EQ per channel, up to four seconds of output delay, adjustable speaker limiting, and real-time load monitoring. Built-in protection functions help safeguard the amplifier and connected loudspeakers during operation.
Designed for networked audio environments, the CONNECT 3004 offers three connection methods: its built-in Wi-Fi access point, an existing venue Wi-Fi network, or wired Ethernet through Cat5 or Cat6 cable. Browser-based WebUI allows configuration from compatible devices without additional software downloads, while LEA Cloud enables remote control, monitoring, and notifications without requiring a VPN. The amplifier also features four balanced analog inputs, external I/O for remote on/off and fault monitoring, and support for third-party API control. The CONNECT 3004 Network Connect model is distinct from the CONNECT 3004D Dante Connect version, which adds Dante connectivity.
