JBL Cinema SA4-D DSi 2.0 Series SA4-D 350W 4-Channel Amplifier

Professional Power Amplifier For Cinema Installations

The JBL Cinema SA4-D is a high-performance four-channel amplifier designed specifically for powering JBL cinema loudspeakers. With advanced digital processing, network integration, and robust power handling, it ensures cinema managers and integrators can deliver consistent, reliable sound in professional theaters. Housed in a 2RU rackmount chassis, this amplifier combines efficiency, flexibility, and long-term durability.

Advanced DSP For Precision Control

Equipped with 96 kHz / 32-bit floating point processing, the SA4-D provides tools normally found only in standalone processors. Features include FIR filtering, crossovers, 8-band parametric EQ, LevelMAX limiting, and up to 1000 ms of delay. This eliminates the need for additional external processors, saving rack space while maintaining accuracy and consistency across the audio system.

DriveCore Technology For Efficiency And Reliability

Crown’s patented DriveCore technology replaces hundreds of components with a single, integrated chip, resulting in superior efficiency, stability, and audio fidelity. The SA4-D offers high power density, providing four bridgeable channels in a compact 2RU design. When configured in 2-ohm mode, a single channel can power up to four surround speakers, maximizing flexibility for modern theater setups.

JBL Cinema Speaker Presets For Optimized Sound

The SA4-D comes with factory-loaded JBL cinema speaker tuning presets, ensuring optimal performance for JBL loudspeakers. These presets manage voltage, crossover points, and EQ curves, protecting transducers from damage while guaranteeing consistent playback quality. For cinema operators, this means faster deployment and a perfectly matched JBL amplifier-and-speaker solution.

Seamless Integration With Theater Management Systems

The amplifier includes SNMP support, allowing direct integration with third-party theater management and cinema control systems. Technicians can remotely monitor amplifier status, recall presets, mute channels, or power the unit on and off through GPIO/AUX ports. This ensures efficient system oversight and minimizes downtime in high-demand theater environments.

Audio Networking With Dante And AES67

For future-ready connectivity, the SA4-D supports Dante and AES67 networking, making it compatible with Dolby Atmos Connect and other networked audio workflows. Dual ports provide redundancy or daisy-chain options, ensuring reliable operation in mission-critical cinema installations. Combined with RJ45 HiQnet support for HARMAN Audio Architect software, the amplifier is fully controllable and configurable over TCP/IP networks.

User Friendly Operation With Intuitive Interface

The SA4-D includes a front-panel LCD screen and encoder for quick setup, monitoring, and control. Technicians can configure amplifier settings, recall presets, or mute channels with ease. With ultra-quiet operation at just 51 dBA maximum fan noise, the amplifier runs silently in projection booths, maintaining a distraction-free environment.
