Controlled and flexible bass management

The SDA-1700 gives you the option to tailor the bass to both the room and the installation. With an adjustable low-pass crossover and built-in EQ, you can fine-tune the reproduction to match the rest of the system. This means the bass is experienced as more coherent and integrated, rather than dominating or falling outside the soundstage.

Tailored to JBL Synthesis subwoofers

The amplifier is optimized for use with JBL Synthesis subwoofers, including the SSW-4, and gives you access to dedicated EQ profiles that match the characteristics of the units. This makes setup easier to manage and ensures that you get a solution that works as a cohesive whole.

Stable performance in a compact rack design

With an output of 700 watts RMS and high peak capacity, the SDA-1700 delivers the power needed to drive larger subwoofer solutions. At the same time, the design is optimized for stable operation, making it suitable for installations where reliability is important. The compact rack format makes it easy to integrate into equipment cabinets or dedicated rack solutions.

Easy integration into the home theater

SDA-1700 is built with installation in mind. The front panel provides access to the most important functions, while connections and advanced settings are placed on the back. This makes it easy to keep the setup clear and manageable, while also providing the flexibility to adapt the system as needed.
