Overview

The SMA-8300 is a versatile 8-channel Class D power amplifier designed to deliver maximum power while taking up minimal rack space. Each channel is rated to deliver 300W into 8 ohms and adjacent channel pairs can be bridged to deliver 600W into 8 ohms. This flexible channel configuration makes this an ideal amplifier to power LCR, surround, height channel loudspeakers as well as subwoofers in JBL Synthesis immersive audio systems. Powerful built-in DSP allows for custom loudspeaker tuning and full external control allows for complete and easy system integration.

The SMA-4750 and SMA-8300 are state-of-the-art Class D multichannel DSP amplifiers that cater to both high-power and high-channel count systems. With advanced features like bridgeable channels, full input and output Hi-Resolution DSP suite, and DANTE / AES67 digital audio networking, these amplifiers are ideal for powering large LCR, surround, and height channel loudspeakers, as well as subwoofers in JBL Synthesis immersive audio systems.

Both models feature a compact, stackable design with quiet side-to-side ventilation, making them perfect for custom installations. They are equipped with a comprehensive DSP suite including EQ, Delay, and Limiters, providing ultimate control and customization for audiophiles and professional installers alike.
