High Definition CINEMA DSP Technology (RX-Z9)

Yamaha was able to fit all the High Definition CINEMA DSP circuitry (that’s a lot of processing power!) on a single board in its own chamber, for greater efficiency and isolation from possible interference.

The RX-Z9 has six times greater DSP capacity than previous models, thanks to an increase from 48kHz to 96kHz/24-bit A/D converters that can accept 96kHz signals for direct digital conversion and processing. Higher density processing enables approximately triple the amount of early reflection data to be handled, for significantly richer surround sound performance.

The RX-Z9 also employs 192kHz/24-bit D/A conversion and DSP processing and Yamaha’s 32-Bit Floating-Point Quantisation System LSIs (four YSS-930s) for high precision decoding of Dolby Digital, DTS Digital Surround, DTS 96/24, DTS-ES Discrete 6.1, DTS-ES Matrix 6.1, DTS Neo:6 and Dolby Pro Logic IIx formats.
