About the DDP-1
The Yamaha DDP-1 Natural Sound Digital Processor is an outboard AC-3 decoder from the mid-1990s, primarily used to upgrade AV receivers like the Yamaha RX-V2090 for full 5.1 Dolby Digital surround sound reproduction. It demodulates and decodes AC-3 signals from RF, coaxial, or optical inputs, typically from laserdisc players, and provides discrete outputs for left/right mains, center, rear left/right, and subwoofer. Featuring three 20-bit DACs, it supports speaker configurations with high-pass filtering (90 Hz crossover) and includes a built-in pink noise generator for level balancing. Volume trim controls allow adjustments for overall output (-9 to 0 dB in 0.5 dB steps) and rear channels (-6 to +6 dB in 1 dB steps). The unit was originally priced around $599 and has been replaced by the DDP-2 model. Current used market prices range from $99 to around $300 depending on condition.
