JBL Professional SA4-D - 4-Channel Power Amplifier with Dante/AES67 and 96 kHz DSP for Cinema

The JBL Professional SA4-D is a DSi 2.0 Series amplifier designed specifically for JBL home theater loudspeakers. It integrates 4 channels with bridgeable outputs into a 2U (19") rack-mount chassis, delivering high power density and advanced system management without the need for external processors. Its Crown DriveCore platform combines efficiency, stability and reliability, while the internal 96 kHz/32-bit floating-point DSP incorporates FIR, parametric EQ, LevelMAX limiting and delays to precisely tailor system response.

The -D model adds Dante/AES67 connectivity with dual RJ-45 ports for primary/secondary networks, allowing direct interface with Dolby Atmos Connect depending on the firmware. Additionally, all DSi 2.0 models include SNMP for integration with room management systems (TMS/NOC) and a HiQnet/Audio Architect port for control, monitoring, and configuration. Outputs are via barrier-type terminal blocks compatible with wiring up to 10 AWG; analog inputs use block connectors (Phoenix).

In terms of performance, the SA4-D delivers 350W x4 into 8Ω (1kHz method, 20ms burst, 2 channels, 0.5% max THD), 700W x4 into 4Ω and 1050W x4 into 2Ω , with bridged options of 1300W x2 into 8Ω and 2200W x2 into 4Ω . Its frequency response is ±0.5dB (20Hz–20kHz into 4Ω), typical THD is 0.35% at rated power, analog SNR >106dB (A-Wtd) and damping factor >1000 (20–100Hz). The fan offers quiet operation, with 51dBA max at 1m. Dimensions (W x H x D): 482 x 88 x 437.2mm ; weight: 10.5 kg .

Main features

• 4 channels with bridgeable outputs in 2U; stable operation at 2–16 Ω per channel and 4–16 Ω bridged.
• 96 kHz/32-bit DSP with FIR, parametric EQ , delays , crossovers and LevelMAX™ limiters .
• Dante/AES67 (-D model) with dual ports for primary/secondary networking; direct interface with Dolby Atmos Connect (firmware dependent).
• Built-in JBL Cinema presets for the entire JBL cinema speaker portfolio.
• SNMP + HiQnet/Audio Architect for control, monitoring, diagnostics and automation (GPIO/AUX 2 in/2 out).
• Crown DriveCore : High power density, efficiency and reliability.
• Low ventilation noise (51 dBA max.) and easy operation via LCD and front encoder.

Product benefits

• Faster, safer deployment : Official JBL presets optimize transducer response and protection.
• Less hardware : Internal 96 kHz DSP eliminates external processing for EQ, FIR filters, delays, and limiting.
• Scalability for immersive : 2 Ω power allows powering up to 4 surround speakers per channel , reducing rack units.
• Modern network integration : Dante/AES67 and SNMP for AoIP streams, centralized control and remote maintenance (TMS/NOC).
• Consistent audio quality : flat response, low distortion and high SNR preserve dialogue and effects.

Use cases

• Cinema complexes with 5.1/7.1 or immersive (Atmos) systems that require high channel density and network control.
• Medium and large rooms where a single SA4-D can group several surrounds per channel at 2 Ω.
• Premium or post-production rooms that require validated presets and control via Audio Architect.

Frequently Asked Questions

• Does the SA4-D need an external processor? Not for basic functions: it includes parametric EQ, filters, delays, FIR, and limiters. It can be supplemented with additional processing if the project requires it.
• How does it integrate with Atmos? The -D model offers Dante/AES67 and can connect with Dolby Atmos Connect (depending on firmware version).
• What is the gain? 32.5/26.5/20.5 dB depending on the selected sensitivity (4/10/16 dBu) at 4/8 Ω.
• What connectors does it use? Analog inputs per block (Phoenix), Dante/AES67 network via 2xRJ-45 (-D model), speaker outputs via barrier terminal block, control via RJ-45 (Ethernet/HiQnet) and GPIO/AUX.
