JBL DSX280D Bottom JBL DSX280-DN, Amp at Bottom

JBL DSX280 HD Bottom-Mounted Amplifier Configuration

The JBL DSX280 HD is a networked loudspeaker system engineered for full-range speech and music reinforcement in medium to large studio monitoring and live recording applications. This bottom-amplifier configuration integrates the 16-channel amplifier module directly beneath the speaker enclosure, streamlining rack integration while maintaining full DSP control and Dante networked audio capability. The system delivers consistent, intelligible coverage across expansive control rooms and tracking spaces with minimal setup complexity.

Coverage & Acoustic Design

Digital Directivity Synthesis technology enables precise beam shaping with 130-degree horizontal coverage and adjustable vertical control, allowing fine-tuned acoustic matching to specific room acoustics and speaker placement. Coverage extends reliably up to 35 meters, making this system suitable for large control rooms, mastering suites, and multi-room studio facilities without requiring additional amplification stages.

Signal Processing & Connectivity

A 32-bit floating-point DSP module provides comprehensive audio shaping through delay, parametric EQ, automatic volume control (AVC), and eight user-definable presets—all accessible via IP control for rapid session switching and A/B comparisons. Dante and analog audio inputs integrate seamlessly with both modern networked audio interfaces and legacy console equipment, while IP connectivity enables remote monitoring and real-time adjustment from workstations throughout the studio.
