The LEA Professional CDS702 Cinema Digital Series Smart Amplifier is a two-channel professional amplifier designed for small- to medium-scale installations. Delivering up to 700 watts per channel at 4Ω, 8Ω, 25V, and 70V/100V, it supports both low-impedance loudspeakers and high-impedance distributed audio systems. With selectable Lo-Z and Hi-Z operation for each channel, the CDS702 provides flexible configuration for commercial audio, cinema, and other installed sound applications.

The CDS702 combines a highly efficient Class-D output stage with proprietary Smart Power Bridge technology and a 96kHz Analog Devices Sigma DSP processor featuring a 32-bit core and sample rate converters. Its integrated processing includes a flexible input-routing matrix, crossover filters up to 48dB per octave, eight-band parametric EQ per channel, adjustable speaker limiters, output delay, and real-time load monitoring. Built-in protection functions help safeguard the amplifier and connected loudspeakers during operation.

Designed for connected audio installations, the CDS702 offers three network connection options: its built-in Wi-Fi access point, an existing venue Wi-Fi network, or wired Ethernet through Cat5 or Cat6 cable. Browser-based WebUI, LEA Cloud, and third-party API control support remote configuration and monitoring. The amplifier also provides balanced analog inputs, an 8 × 8 AES67 interface, and external I/O for remote on/off control and amplifier fault monitoring.
