The LEA Professional CS702-G Connect Series Smart Amplifier is a two-channel Class-D amplifier designed for small to medium-sized professional audio installations. It delivers 350 watts per channel at 2Ω and 700 watts per channel at 4Ω and 8Ω, as well as 25V, 70V, and 100V operation. Its proprietary Smart Power Bridge technology supports bridged output functionality, while selectable low-impedance and high-impedance operation provides flexibility for different loudspeaker configurations.

The CS702-G incorporates a 96kHz Analog Devices Sigma DSP processor with a 32-bit core and sample rate converters. Its processing features include IIR crossover filters up to 48dB per octave, eight-band parametric EQ per channel, input routing, and up to 100 milliseconds of output delay per channel. User-adjustable peak and RMS voltage limiters, real-time load monitoring, and pilot-tone detection help optimize loudspeaker performance and support reliable system operation.

Designed for networked installations, the CS702-G provides two balanced analog inputs and wired LAN connectivity for system management. LEA Cloud enables remote control, monitoring, and notifications without requiring a VPN, while the browser-based WebUI and third-party API offer additional control options. Unlike other Connect Series models, the G-Model requires a wired LAN connection and does not support Wi-Fi, making it suitable for installations with established Ethernet infrastructure.
