Oklahoma City, OK, September 6, 2016 — DD Audio has just released the new SS4b, a discrete circuit full range class D amplifier that cranks out over 350 watts x 4 at 2Ω stereo with less than 1% THD+N.

SS4b key features include:

• Conformal coated circuit boards for reliable functionality in any install environment.
• Tiffany RCA jacks for solid and durable connections
• Individually selectable high and low pass crossovers covering 20Hz-5KHz
• Compact footprint for easy install in applications where space is limited
