Krell Industries KPS-30i manual Introduction

INTRODUCTION

Thank you for your purchase of the KRELL PLAYBACK SYSTEM-30i.

Derived from the KRELL PLAYBACKSYSTEM20 series, the KPS-30i benefits

from the same advanced digital reconstruction system; input and output

flexibility, ergonomics, and stunning aesthetics. The KPS-30i represents an

impressive addition to the formidable KRELL PLAYBACKSYSTEMfamily of components.

The KPS-30i is a top-load design based on a high performance Philips transport

mechanism. The transport is housed in a solid machined block of aluminum

and independently suspended from the chassis by low-stored-energy isolation mounts. The main chassis provides the first line of shock energy isolation with

its own series of low-stored-energy suspension mounts, leaving the inertially

massive aluminum laser chassis to dissipate any residual energy before it can

influence the tracking of the laser. Disc stabilization is accomplished with a

custom magnetic clamping system. The heavy cover assembly isolates the compact disc from ambient light.

The KPS-30i transport mechanism is coupled to an upgradeable software based

processor, providing jitter-free playback. Data is transferred through custom

filter algorithms performing proprietary KRELLreconstructive software at a

16X oversampling rate through a Motorola DSP processor running at

66 MHz. The 24 bit data is then fed to four differentially configured Burr Brown 20 bit Colinear DAC's.

HDCDdecoding hardware will be available as an option for the KPS-30i. If

installed, the KPS-30i will automatically recognize an HDCDencoded disc and

direct the digital signal through the Pacific Microsonics PMD-100 HDCD

decoding chip. For standard discs, the KPS-30i will use the same KRELL

custom filter algorithms utilized in a non-HDCDequipped KPS-30i.
