LEA Connect 704
The LEA Connect 704 is a four-channel professional smart amplifier designed for small- to medium-scale AV installations. It delivers up to 700 watts per channel and supports both low-impedance (Lo-Z) and high-impedance (Hi-Z) speaker systems, with 70V or 100V operation selectable per channel. Built-in Wi-Fi, Ethernet networking and cloud connectivity enable remote configuration, monitoring and control from a web browser or compatible control platform.
- Four amplifier channels, rated at 700 W per channel.
- Direct Lo-Z and Hi-Z operation, including selectable 70V/100V.
- Built-in Wi-Fi access point, existing Wi-Fi network and Ethernet connectivity.
- LEA Cloud remote monitoring, control and notifications.
- Smart Power Bridge technology for bridging without sacrificing another amplifier channel.
- 96 kHz digital signal processing (DSP).
- Eight-band parametric EQ per channel.
- Input routing matrix, crossover filters and speaker limiters.
- Real-time load monitoring and external I/O for remote on/off and fault monitoring.
- Efficient Class-D amplifier output stage
