INTRODUCTION

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

Derived from the KRELL PLAYBACK SYSTEM 20 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 PLAYBACK SYSTEM family 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 KRELL reconstructive 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.

HDCD decoding hardware will be available as an option for the KPS-30i. If installed, the KPS-30i will automatically recognize an HDCD encoded 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-HDCD equipped KPS-30i.

All critical circuitry utilizes four layer glass epoxy circuit boards. With its 100 VA

power supply and 11 independent stages of regulation, the power supply of the KPS-30i is a rock solid source of pure current and voltage for the digital and

Class A analog output stages. The output stage is classic KRELL. All output circuits are DC coupled, Class A, and complementary. The output stage has 18 volt rails and fully differential balanced outputs on gold plated, beryllium copper XLR connectors. Single ended outputs are also provided via custom gold plated RCA connectors.

The KPS-30i includes four digital input formats: one AES/EBU balanced, two

SPDIF coaxial, and one EIAJ optical. It comes standard with AES/EBU balanced, ELA_J optical and SPDIF coaxial digital outputs. All input switching is accessible from the front panel or the remote control. KRELL’s proprietary Data Recovery and Jitter Rejection Module recovers all data from external sources, reducing

jitter to exceptionally low levels.

This Owner’s Reference is intended to guide the clear, trouble free installation and operation of your KPSt30i. Should you have any questions or comments,

please feel free to contact your authorized dealer or the KRELL staff for assistance.

In the unlikely event that your KPS-30i should require service, you will be pleased to know that it is backed by a comprehensive Customer Satisfaction

policy and one of the most advanced service facilities in the industry.. For detailed information on the terms and conditions of service, please consult the

Warranty and Service section of this Reference, Warranty Registration Card, Or an authorized KRELL Dealer/Distributor.

UNPACKING AND PLACEMENT

1. Once the box is opened and top layer of foam removed, the following items will be visible:

1 KPS-30i 1 KPS-30i Remote Control 1 KPS-30i Custom CD clamp 1 AC power cord 1 Packet containing the Owner’s Reference and Warranty

Registration Card

NOTE: If any of these items are not included, please contact your authorized dealer immediately for assistance.

2. Carefully remove the unit and accessories from the box. Remove the protective plastic wrap from the unit.

NOTE: Save all packing materials. If you must ship your KPS-30i in the future,

repack the unit in its original packaging to prevent transit damage. KRELL is not responsible for damage incurred during the shipment of goods without factory approved packing material.

PLACEMENT

Before you install the KPS-30i into your system, we recommend that you

follow these guidelines in choosing the location. This .will facilitate a clean,

trouble-free installation. The KPS-30i does not require any type of special rack or cabinet for installation. Dimensions are described on page 17.

1. Place the unit on a firm level surface away from excessive heat, humidity or moisture. Make sure there is enough room at the top for a compact disc to be placed within the chassis. Approximately ten inches is necessary.

Although well shielded, the KPS~30i should not be placed in close proximity

2. to hum sensitive components such as preamp phono stages or turntables.

The power supply may create interference and induce hum..~

3. The KPS-30i incorporates an advanced suspension system and does not require additional mass coupling or isolation. You may experiment with feet or cones as long as they don’t permanently affix to the chassis. Any unauthorized modifications to the electronics or chassis will void the warranty.

GENERAL DESCRIPTION OF KPS-30i OWNER’S REFERENCE

The features, functions, and operation of the KPS-30i are divided into two

sections: Basic Operation provides a quick installation procedure; Complete

Transport Features and Functions provides details on all KPS-30i transport

capabilities.

As with all sophisticated products, a complete reading of this Owner’s

Reference will provide a thorough understanding of the KPS-30i. Please contact

your authorized dealer, distributor, or the factory if you have any questions not

addressed by this Reference.

IMPORTANT NOTE: The use of CD rings, mats, or other devices attached to

individual CDs is not recommended. To be completely effective, the KPS-30i clamp must make direct contact with the CD. Otherwise, erratic playback and~or

poor sound may occur.

AC POWER GUIDELINES

The KPS-30i has superb regulation and does not require a dedicated AC

circuit. We strongly advise against connections through extension cords or multiple AC adapters. High quality 15 amp grounded AC strips are acceptable.

High quality AC line conditioners or filters can be utilized if they are grounded and meet or exceed the unit’s power supply rating of 100 VA.

CAUTION: Do not remove or bypass the ground pin on the end of the AC cord.

This may cause RFI (radio frequency interference) to be induced into your

playback systerra
