Cinema managers and integrators looking to maximize their power investment and future-proof their systems will be thrilled with the Crown Audio DSi-Series SA4-D, a 350W 4-channel power amplifier that's designed for JBL cinema loudspeakers offering outstanding quality and performance in a rack-mountable enclosure.
The amplifier features a remarkable 96 kHz/32-bit digital signal processing with delay, 8-band parametric EQ, crossovers, FIR processing, LevelMAX limiting, and more. The integrated DriveCore technology incorporates hundreds of amplifier components into a single chip for superior efficiency and reliability. With its updated design, the SA4-D allows for high power output at 2 ohms, enabling up to four surround speakers to be powered by a single channel. There are built-in cinema speaker tuning presets that match all JBL cinema loudspeakers for optimal performance, protection, and easy deployment.
The font panel features an LCD and encoder to configure amplifier settings and mute channels at the touch of a button. The rear panel provides four analog inputs via two Euroblock connectors and two terminal strip speaker outputs to connect up to four speakers. A HiQnet (RJ45) port allows the amplifier to connect with HARMON Audio Architect control software over a standard TCP/IP network. A GPIO/AUX port allows you to externally recall presets, mute channels, monitor amplifier health and power the amplifier on or off. The LA4-D includes DANTE/AES67 support for seamless integration with Dolby Atomos Connect and other interfaces.
