Experience precise audio clarity with a wider dynamic range when using the higher bit and sample rates that the R-09HR offers. The R-09HR supports up to 24-bit/96kHz linear PCM recording, which has over twice the digital audio resolution of a standard audio CD. I.A.R.C. (Isolated Adaptive Recording Circuit) is a newly developed, dedicated analog circuit optimized for recording with the R-09HR's onboard A/D converter. Electrolytic capacitors provide stable, reliable power with an independent power source for the analog circuitry, and another power source for the digital circuit board, thus eliminating DC interference between components in the R-09HR. The I.A.R.C. also contributes to high-quality, low-noise MP3 recording with the R-09HR.
