Although a HDCD-compatible CD player is usually required to exhibit the full characteris-tics of the HDCD, this receiver is capable of reproducing high-qualityHDCH signals by connecting a CD player through digital connection,even when it does not incorporate the HDCD circuitry.D.R.I.V.E. is a KENWOOD original technology for reproducing signalswith high resolution by instant switching of the internal filters accordingto the input signal. This receiver incorporate a high performance DSP toprovide very high resolution from 32-bit DRIVE III circuitry, achievingstereo audio reproduction with the best quality ever reached.The D.R.I.V.E. indicator lights when the D.R.I.V.E. circuit is activated.The HDCD indicator lights when the HDCD circuit is activated and aHDCD is played.HDCD and D.R.I.V.E. are designed to be activated automatically to selectthe optimum circuit path., HDCD®, High Definition Compatible Digital® and PacificMicrosonics TM are either registered trademarks or trademarks of PacificMicrosonics, Inc. in the United States and/or other countries.
