World-class Amplification for Your Subs

Optimized for world-class performance and reliability, the JBL Synthesis SDA-1700 is tailor-made for custom installation environments. This rackmountable, Class D subwoofer amplifier delivers 1,500 watts of peak power across two channels, enabling you to drive up to two SSW-4 in-wall subs. The SDA-1700 features installer-focused rear-panel connectivity and user-accessible front-panel controls, bolstered by two EQ modes optimized for in-wall installations and a user-adjustable single-band parametric EQ for room tuning. Signal sensing powers the amplifier up when in use and powers it down after a period of silence to save energy. You also get built-in short-circuit and over-current protection, along with over-temperature compensation, making the SDA-1700 a no-compromise solution for JBL Synthesis in-wall subwoofer systems.

Note: JBL Synthesis products can only be purchased through a certified Sweetwater Sales Engineer. Please call us if you have questions.
