The LEA Professional CDS1504 Cinema Digital Series Smart Amplifier is a four-channel professional amplifier delivering up to 1,500 watts per channel for demanding cinema and commercial audio installations. It supports low-impedance loudspeakers and high-impedance 70V/100V distributed systems, with output modes selectable independently for each channel. Its high-power design makes it suitable for small- to medium-scale installations that require flexible speaker configuration and reliable amplification.

The CDS1504 features a highly efficient Class-D output stage, proprietary Smart Power Bridge technology, and a 96kHz Analog Devices SHARC DSP processor with a 32-bit core and sample rate converters. Its processing capabilities include 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 peak and RMS voltage limiting, and real-time load monitoring. Integrated protection functions help safeguard the amplifier and connected loudspeakers during operation.

With three networking options, the CDS1504 can connect through its built-in Wi-Fi access point, an existing Wi-Fi network, or wired Ethernet using Cat5 or Cat6 cable. Browser-based WebUI provides configuration from compatible devices without requiring additional software downloads, while LEA Cloud enables remote control and monitoring from virtually anywhere without a VPN. Additional features include balanced analog inputs, an 8 × 8 AES67 interface, and external I/O for remote on/off control and amplifier fault monitoring.
