The JBL SDA-1700 Class D Subwoofer Amplifier is a dedicated high-output amplifier engineered for JBL Synthesis architectural subwoofer systems. Designed with both performance and custom installation in mind, the SDA-1700 delivers 700 watts RMS into its minimum 4-ohm load and up to 1,500 watts of peak power, providing the output required for powerful, controlled low-frequency reproduction in premium home cinema systems.
Purpose-built tuning options distinguish the SDA-1700 from a conventional power amplifier. Dedicated model-specific EQ settings optimize operation with JBL Synthesis SSW-4 and JBL C82W subwoofers, while adjustable low-pass crossover, phase, single-band parametric EQ, and front-panel level control provide additional tools for integrating bass performance with the room and main loudspeaker system. A compact 2U rack-mountable chassis, automatic signal sensing, dual subwoofer outputs, and comprehensive protection circuitry make the SDA-1700 equally focused on performance, reliability, and professional system integration.
Key Features & Innovations
700-watt RMS Class D amplification — the JBL SDA-1700 Class D Subwoofer Amplifier delivers 700 watts RMS into a 4-ohm minimum load, providing substantial power for compatible JBL Synthesis architectural subwoofer systems.
1,500 watts of peak power — high peak-output capability gives the amplifier the dynamic headroom required for demanding low-frequency effects in dedicated home theaters.
Designed for JBL Synthesis architectural subwoofers — the SDA-1700 is purpose-built for JBL's custom-installation subwoofer solutions rather than functioning as a generic full-range power amplifier.
Dedicated SSW-4 EQ mode — a model-specific equalization setting optimizes amplifier response specifically for the JBL Synthesis SSW-4 in-wall subwoofer.
Dedicated C82W EQ mode — a second model-specific EQ setting provides optimized operation when the amplifier is used with the compatible JBL C82W architectural subwoofer.
Adjustable low-pass crossover — rear-panel crossover adjustment from 50Hz to 150Hz provides additional flexibility when integrating the subwoofer system with the main loudspeakers and AV processor.
Single-band parametric room EQ — user-adjustable PEQ provides a useful tool for addressing a problematic low-frequency room resonance and improving bass integration at the listening position.
Phase adjustment — rear-panel phase control assists with aligning the subwoofer system to the main loudspeakers for more coherent bass reproduction through the crossover region.
Automatic signal-sensing operation — the amplifier can automatically detect an incoming audio signal and transition between active and standby operation for convenient everyday use.
Comprehensive protection circuitry — short-circuit and over-current protection along with over-temperature compensation help protect the amplifier and connected subwoofer system during demanding playback.
Custom-installation focused design — front-panel user controls are combined with installer-oriented rear-panel adjustments and a compact 2U rack-mountable chassis for clean integration into a dedicated AV equipment rack.
FAQ — JBL SDA-1700
How much power does the JBL SDA-1700 produce?
The SDA-1700 is rated to deliver 700 watts RMS into its minimum 4-ohm load and provides up to 1,500 watts of peak output.
How many JBL Synthesis SSW-4 subwoofers can one SDA-1700 power?
One SDA-1700 can be used with either one or two SSW-4 in-wall subwoofer modules. JBL specifies approximately 350 watts for a single SSW-4 configuration and 700 watts when powering a pair of SSW-4 subwoofers.
Which JBL subwoofers have dedicated EQ settings in the SDA-1700?
The amplifier provides two model-specific EQ modes. EQ 1 is designed for the JBL Synthesis SSW-4, while EQ 2 is designed for the JBL C82W.
Does the SDA-1700 include room equalization?
Yes. In addition to its model-specific subwoofer EQ settings, the SDA-1700 provides an adjustable single-band parametric EQ that can be used to help compensate for a problematic bass resonance within the listening room.
Does the SDA-1700 have an adjustable crossover?
Yes. The amplifier provides an adjustable low-pass crossover covering 50Hz to 150Hz. This allows the installer to tailor the upper-frequency limit of the connected subwoofer system when required by the overall system design.
Is the SDA-1700 rack mountable?
Yes. The SDA-1700 is designed for professional custom installation and occupies two rack spaces in a standard equipment rack.
