JBL Professional MA4-D - 4-Channel Amplifier with 96 kHz DSP and Dante/AES67 for Home Theater

The JBL Professional MA4-D is a 4-channel power amplifier designed for home theaters and professional environments requiring high power density, reliability, and easy integration with networked audio systems. It belongs to the DSi 2.0 series and combines 96 kHz/32-bit signal processing with Crown DriveCore technology, delivering robust performance in a standard 2RU chassis. The D version adds Dante/AES67 connectivity for interconnecting IP sources and matrix arrays, as well as direct interface to Dolby Atmos Connect without additional hardware. In addition, it includes JBL Cinema speaker presets , SNMP monitoring and control, and HARMAN Audio Architect management, streamlining commissioning and protecting your system.

With bridgeable outputs, high throughput at 2 Ω , and quiet cooling (51 dBA max.), the MA4-D can power everything from screen channels to surround arrays with a single unit. Its front-facing LCD and encoder facilitate on-site setup, while GPIO/AUX connections allow preset recall and basic external control. All this comes in a 19"/2RU format and weighs 10.5 kg , ready for exhibition and post-production racks.

Main features

• 4 channels with bridgeable outputs to cover screen, surround and sub lines with a single chassis.
• Internal 96 kHz / 32-bit DSP with FIR, 8-band parametric EQ, LevelMAX limiting and delays.
• Dante/AES67 connectivity (2× RJ45) on the MA4-D model for audio over IP and support for Dolby Atmos Connect .
• JBL Cinema presets preloaded across the range, optimizing performance and setup times.
• Crown DriveCore : Greater efficiency, stability and power density.
• Control and monitoring by SNMP , HiQnet port (Audio Architect) and GPIO/AUX connector (2 inputs / 2 outputs).
• Low fan noise : 51 dBA max. at 1 m.
• 2RU, 19” format , with terminal block outputs (up to 10 AWG cable) and analog inputs per block .

Power specifications

Values ​​per channel unless otherwise stated ( 1 kHz, 20 ms burst, 2 channels conducted, 0.5% THD max. ):

• 8 Ω: 750 W × 4
• 4 Ω: 1,400 W × 4

Product benefits

• Faster setup with official JBL presets and centralized control with Audio Architect.
• Less hardware : Integrated DSP eliminates external processors in many rooms, reducing space and complexity.
• Ready for immersive formats : direct integration with Dolby Atmos Connect in version D.
• Scalability and flexibility : 2 Ω mode for grouping multiple surrounds per channel or high power bridged for screen paths.
• 24/7 reliability with SNMP monitoring and DriveCore technology for greater thermal efficiency and stability.
• Contained operating noise helps meet quiet cabin and room requirements.

Use cases

• Medium and large 5.1/7.1 cinemas and immersive (Atmos) installations.
• Booth modernization with migration to audio over IP (Dante/AES67) while maintaining analog compatibility.
• Multi-room complexes requiring remote monitoring (NOC/TMS) and predictive maintenance.

Frequently Asked Questions

• Does the MA4-D support Dolby Atmos Connect? Yes, the D version offers direct digital connectivity to Atmos Connect interfaces via Dante/AES67.
• Can I use it as a bridge? Yes, it supports bridging at 8 Ω and 4 Ω (see power ratings). Supported bridge load: 4–16 Ω.
• How many surround speakers can I group per channel? In high-output mode at 2 Ω, up to four surround speakers can be powered per channel (depending on the appropriate power/limiting).
• What software is it configured with? HARMAN Audio Architect via HiQnet port, plus SNMP control for TMS/NOC.
