Special features

DOLBY PRO LOGIC & DOLBY 3 STEREO

The surround system reproduces video software programs carrying the mark with similar acoustic effects to movie
theaters.
The DOLBY PRO LOGIC mode controls the audio signals of the Front Left/Right, Center and Rear surround channels using the built-in
directivity enhancer circuit to reproduce the feeling of sound motions very realistically.
The DOLBY 3 STEREO mode can reproduce the motions of sound even when only the front and center speakers are used, by providing proper
acoustic position using the directivity enhancer circuit.

SRS 3D Stereo

The SRS (Sound Retrieval System) is an innovative system simulating a 3-dimensional sound space, which features clearly improved
feelings of depth, sound field extension and acoustic image positioning as well as a widened listening area.

About the system control connections

6

Connecting system control cords after connecting a KENWOOD audio component system lets you take advantage of convenient
system control operations.
There are two KENWOOD system control modes. Make connections according to the groups of terminal symbols shown below.

ƒ Mode: lets you combine F, f, and ƒ terminals

Mode: for terminals only

This unit is compatible with both [XS8] and [SL16] modes. It comes from the factory set to the [SL16] mode. To switch to the [XS8]
mode, follow the instructions in “SWITCHING BETWEEN [XS8] AND [SL16]” below.

EXAMPLE: [XS8] mode connections
The underlined portion represents the setting of the system
control mode.

Turntable

[SL16] [XS8]

[SL16]

[SL16] [XS] [XS8] [XR]

[SL16] [XS] [XS8]

÷ Some CD players and cassette decks are not compatible with the [SL16] system control mode. Be sure to use the [XS8] system control mode when

making system connections with equipment that is not [SL16] compatible.

÷ Some MD players are not system control compatible. You cannot make system control connections to this kind of equipment.

1. [SL16] equipment cannot be combined with [XR], [XS], and [XS8] equipment for system operations. If your
equipment consists of this kind of combination, please do not connect any system control cords. Even
without system control cords, normal operations can be carried out without affecting performance.

2. Do not connect system control cords to any components other than those specified by KENWOOD. It may
cause a malfunction and damage your equipment.

3. Be sure the system control plugs are inserted all the way in to the system control terminals.

ABOUT THE SYSTEM CONTROL OPERATIONS

Remote Control (possible when the system control mode

matches)

Lets you operate source components with the system remote
supplied with this unit.

Automatic Operation (Except [XR] equipment)

When you start playback from a source component, the input
selector on this unit switches to that component automatically.
(Except TAPE 2)

Synchronized Recording (Except [XR] equipment)

Lets you synchronize recording with the start of playback when
recording from CD or MD.

1. Connect all cords firmly. If connections are loose, there could be loss of sound or noise produced.

2. When plugging and unplugging connection cords, be sure to first remove the power cord from the AC outlet. Plugging / unplugging connection
cords without removal of the power cord can cause malfunctions or damage to the unit.

3. If the system control cords or audio cords are not connected properly, the remote control or automatic operation between system components
will not work properly.

SWITCHING BETWEEN [XS8] AND [SL16]

The system control mode can be switched over easily with the
following operation.

1 Unplug the AC power cord from the wall outlet.
2 Set the SYSTEM CONTROL switch on the rear panel to the desired

position.

÷ This operation does not affect the items stored in memory.

The supplied antenna is for indoor use. Place it as far as possible from the
main system, TV set, speaker cords and power cord, and set it to a
direction which provides the best reception.

The illustration shows the KR-797.

FM indoor antenna connection

The accessory antenna is for temporary indoor use only. For stable signal
reception we recommend using an outdoor antenna. Remove the indoor
antenna if you connect one outdoors.

Pull out while rotating.

Lead the 75 Ω coaxial cable connected to the FM outdoor antenna into
the room and connect it to the FM 75 Ω terminal.

When using a commercially-available
T-shaped indoor antenna (300 Ω),
connect it to these terminals.

(Except for U.S.A. and Canada)

The FM DE-EMPHASIS / CHANNEL SPACE switch on the rear panel is
set to the correct setting that prevails in the area to which the unit is
shipped. However, if the FM DE-EMPHASIS / CHANNEL SPACE setting
is not matched to the area where the unit is to be used; for instance,
when you moved from area 1 to area 2 or vice versa, desired reception
of AM / FM broadcasts is not expected. In this case, change the FM DE­EMPHASIS / CHANNEL SPACE setting in accordance with the area
corresponding to the table. The FM DE-EMPHASIS is switched over at
the same time.

KR-897/KR-797 (En)

÷ When changing the setting of the FM DE-EMPHASIS / CHANNEL

SPACE switch, first disconnect the power cord of the amplifier, then
reset the channel space switch, connect the power cord again, and turn
the power on.
