Placement

WARNINGS

The Krell Playback System

located where it could be exposed to drip-

ping or splashing fluids.

Before you install the KPS 25s into your
system, review the following guidelines to

choose the location for the KPS 25s. This
will facilitate a clean, trouble-free installation.

The KPS 25s does not require a special rack

or cabinet for installation. Forthe dimensions

of the KPS 25s see Specifications on page

20.

1. Place the KPS 25s on a firm level sur­face, away from excessive heat, humi-

dity or moisture.

2. The KPS 25s 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 are not perma-

nently affixed to the chassis. Any unau-

thorized modifications to the electronics

or chassis will void the warranty.

IMPORTANT: Please do not attach
enhancement accessories such as rings,
mats, or dampers to individual CDs. These

TM

must not be

accessories may cause problems with the

transport mechanism, resulting in erratic

playback and/or poor sound.

AC Power Guidelines

WARNING

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 system.
The KPS 25s has superb regulation and

does not require a dedicated AC circuit.
Avoid connections through extension cords

or multiple AC adapters. High quality 15 amp
grounded AC stdps are acceptable. High

quality AC line conditioners or filters can be

used if they are grounded and meet or

exceed the unit’s power supply rating of 100

VA.

Installing the Acrylic

Cover

Install the Acrylic Cover onto the top of the

KPS 25s, before connecting the KPS 25s to
your system. Follow the easy steps outlined
on pages 5, 6, and 7.

Connecting the KPS 25s

to Your System

WARNING

When making connections to this compo­nent or any other, make sure the power

amplifier is Off. Make sure all cable termi­nations are of the highest quality, free from

frayed ends, shorts, or cold solder joints.

more gain than single-ended connections.

When level matching is critical, keep this

specification in mind.

NOTE: Both ba/anced and single-ended
outputs can be used to simultaneously feed

different systems.

When the KPS 25s is connected directly to
a stereo power amplifier or a pair of monau-

ral power amplifiers, use the variable output

terminals to insure proper level control.

Additional Connections

RC-5

The RC-5 input makes custom installation
easy and secure by accepting baseband

RC-5 input commands from hardwired
remote controllers.

12 VDC OUT

The remote power output transmits 12 Volt

power on/off signals to other KrelP compo­nents, as well as to other components that

accept 12 Volt power on/off trigger com-

mands.

Remote Control Operation

The KPS 25s is equipped with two remote
controllers. The KPS 25s Handheld Remote

Controller provides the basic functions of
Power, Play, .Pause, Stop, Track, and Level.

The KPS 25s Tabletop Remote Controller,

named the Direct Access Controller, pro­vides complete CD transport functions as
well as KrelP preamplifier and power ampli-

fier remote control functions. A description
of the buttons and their functions follows.

NOTE: The Tabletop Remote Controller
®

also includes functions used with Krell
amplifiers.

NOTE: Consult the owner’s reference of
the components used in a custom installa-

tion to take full advantage of the remote
capability of the KPS 25s.

KRELL® KPS 25s

Warranty

THERE ARE NO USER-SERVICEABLE

PARTS INSIDE ANY KRELL PRODUCT.

The KPS 25s KrelP Playback System has a

limited and transferable warranty of five
years for parts and labor and three years on
transport related parts. The warranty period

begins on the date of retail purchase, as

noted on the retail sales slip provided by an

authorized Krell® dealer or distributor, or on
the warranty registration card sent to KrelP.

In the event adequate proof of purchase

date is unavailable, the warranty period will

begin on the date the unit was originally

shipped from the factory. The original ship

date can be determined by KrelP from the

serial number.

The warranty for KrelP products is valid only

in the country to which they were originally

shipped, through the authorized KrelP dis-

tributor for that country, and at the factory.

There may be restrictions on, or changes to

Krell’s warranty because of regulations

within a specific country. Please check with

your distributor for a complete understand-

ing of the warranty in your country.
Freight to the factory is your responsibility.

Second day return freight within the United

States (U.S.A.) is included in the warranty.

If you have purchased your KrelP product
outside the U.S.A. and wish to have it ser-

viced at the factory, all freight and associ-

ated charges to the factory are your respon­sibility. KrelP will pay return freight to the

U.S.A.-based freight forwarder of your
choice. Freight and other charges to ship
the unit from the freight forwarder to you are
