Introduction Definition of Terms
Thank you for your purchase of the Krell
KAV-300r Stereo Receiver with Theater
Throughput. The KAV-300r gives the audio-
phile an exceptional-sounding, two-channel music system in a convenient package that can stand alone or easily be integrated into a multi­component system. The tuner combines strong
reception and quality sound with transparent functioning and can be operated through the front panel or the remote. Six programmable
tuner presets allow instant selection of your
favorite AM or FM stations. The FM mute and
high frequency blend features also let you con-
trol background and between-station noise
when selecting FM stations with weaker broad-
cast signals.
The Theater Throughput feature simplifies the
integration of an audio/video surround sound
processor into your system. The remote pro-
vides convenient operation of-the KAV-300r
and other Krell KAV components.
This owner’s reference manual contains impor-
tant information on placement, installation, and
operation of the KAV-300r. Please read this
information carefully. A thorough understanding of these details will help ensure satisfactory operation and long life for your KAV-300r and
related system components.
Following are the definitions of key terms used in your owner’s reference manual.
CONFIGURATIONS Theater Throughput
Theater Throughput is a Krell configuration option that allows the signal from a surround preamp/pro­cessor to pass through a Krell preamplifier or inte-
grated amplifier with no gain, for integrated vol­ume and balance management of Krell home theater systems.
INPUT AND OUTPUT CONNECTIONS
Balanced
A symmetrical input or output circuit that has equal impedance from both input terminals to a common ground reference point. The industry standard for professional and sound recording
installations, balanced connections have 6 dB more gain than single-ended connections and allow the use of long interconnect cables.
Balanced co0nections are completely immuneto
induced noise from the system or the environ-
ment.
Single-ended
A two-wire input or output circuit. Use care when
using single-ended connections as the ground
connection is made last and broken first. Turn the
system off prior to making or breaking single-
ended connections. Single-ended connections
are not recommended for connections requiring
long cable runs.

Placement
Before you integrate the KAV-300r into your system, review the following to properly place
your component. This will facilitate a clean, trouble-free installation.
For installations inside cabinetry, extra ventila-
tion may be necessary. The KAV-300r requires at least two inches (5 cm) of clearance on each side and at least two inches (5 cm) of clearance
above to provide adequate ventilation. The
KAV-300r does not require a special rack or cabinet for installation. For the dimensions of the KAV-300r, see Specifications, on the back cover.
The KAV-300r is not particularly hum-sensitive. Other components may be placed on or around the KAV-300r, as long as the ventilation grids
remain unobstructed.
Note
Some televisions and fluorescer~t lights generate
high levels of AM radiation, which can interfere
with AM reception. Electro-magnetic radiation from some radio receiving and transmitting equipment (such as televisions, video recorders, digital equipment, and computers) can also cause noise and interference.
Place the KAV-300r as close to the speakers as possible. Run long balanced interconnect cables
to the receiver and keep speaker cable lengths to
a minimum. Speaker cable adds impedance to
the load the amplifier must drive, regardless of the
cable gauge.
AC POWER GUIDELINES
The KAV-300r has superb regulation and does not require a dedicated AC circuit. Avoid con-
nections through extension cords or multiple AC adapters. High quality 15 amp grounded AC strips are acceptable. High quality AC line con­ditioners or filters may be used if they are grounded and meet or exceed the component’s
power supply rating of 400 VA.
Power Cord
The KAV-300r should be operated only with the
power cord supplied. Please contact your authorized Krell dealer, distributor, or Krell
before using any devices designed to alter or
stabilize the AC power for the KAV-300r.

Optional Configurations
CONFIGURING THE KAV-300r
FOR THEATER THROUGHPUT
To simplify the integration of an audio/video sur-
round sound processor into your system, set any
KAV-300r input (S-1, S-2, S-3, or B-l) to operate as a unity gain stage. Krell calls this configuration Theater Throughput. When you configure a
KAV-300r input for Theater Throughput, the
KAV-300r volume and balance controls are transferred to the audio/video surround sound
processor, for integrated volume and balance
management and ease of operation. As long as the KAV-300r input is configured for Theater Throughput and connected to the audio/video
surround sound processor’s input configured for Theater Throughput, all KAV-300r volume and
balance adjustments are made through the sur-
round sound processor. When you disengage the KAV-300r input from Theater Throughput, the volume and balance controls revert to the
KAV-300r.
How to Activate an Input
for Theater Throughput
IMPORTANT
Always turn off the source component before
you configure any input for Theater Throughput.
1. Turn on the KAV-300r power using the power
button (3).
2.
Press and hold the button for the input to be. configured for Theater Throughput, for three
seconds.. The Theater Throughput LED (14) illuminates.
3.
Use the corresponding input on the back panel to connect the KAV-300r to your audio/video surround sound processor.
IMPORTANT
Make sure that the source component is a sur­round sound processor. Other source compo-
nents should not be connected to an input con-
figured for Theater Throughput. Doing so can result in excessive and possibly damaging vol­ume levels when the source is played. Always turn off the source component before you con­figure any input on the KA V-3OOr for Theater
Throughput.
How to Disengage an Input for Theater Throughput
1. Turn on the KAV-300r power using the power button (3).
Press and hold the button that corresponds to
the input configured for Theater Throughput, for three seconds.
3. Theater Throughput is disengaged when the Theater Throughput LED (14) turns off.
PREAMPLIFIER OUTPUT
The KAV-300r is equipped with a pair of single­ended preamplifier outputs (25). These outputs allow the KAV-~ 300r to be used as a preamplifi:
er when it is connected to a separate amplifier.
Note
The amplifier channel outputs are always active, even when the KAV-3OOr is only being used as a preamplifier.
ADJUSTING CONTRAST AND BRIGHTNESS OF THE TUNER DISPLAY
The contrast and brightness of the tuner display
(5) can be adjusted using the screws located the underside of the KAV-300r unit. To increase tuner display contrast, turn the screw closest to the KAV-300r front edge.clockwise. To increase tuner display brightness, turn the screw furthest
from the front edge counterclockwise. Use the trimmer adjustment tool provided.

How to Troubleshoot
System Noise
Questions and Answers
AC grounding becomes critical when connect­ing high performance audio components. When you mix and match audio components, each with its own ground potential, a low frequency hum may occur in one or both speakers. This often occurs when connecting new components
into a system.
If a low frequency hum emanates from the speakers when you place the KAV-300r into the system, follow these simple troubleshooting
steps before contacting your authorized Krell
dealer, distributor, or Krell.
1. Check all input and output connections,
making sure they are of sound construction. With the receiver off, remove the intercon­nect cables, then turn the receiver on. If the
hum disappears, turn the receiver off and reinsert one of the interconnect cables. Turn the receiver back on. If the hum reappears with one or both interconnects inserted,
there may be a defective cable. Have the
interconnect cables checked before pro-
ceeding.
2. If the interconnects prove to be sound, you may be experiencing a ground loop. Please
contact your authorized Krell dealer, distrib-
utor, or Krell for suggestions on how to
solve this problem.
See Placement, on page 3, for information about electromagnetic radiation that can cause noise and interference.
Q. When I turn up the volume on the KAV-300r, there is a loud hum from the loudspeakers; what could it be?
A. Hum can be caused by several different dis­turbances. Check to make sure all cables into and out of the KAV-300r are sound and making
proper contact. Also make sure there are no power supplies or hum inducing components on top of or directly below the KAV-300r. Another
possible source of hum could be a ground loop in the system. Please contact your authorized Krell dealer, distributor, or Krell for suggestions on solving this problem.
Q. When I select the B-1 input on the KAV-300r, one channel seems to have less gain than the other. Is something wrong with the preamplifier?
A. First check the balance LEDs. If the balance
has been set off center, the red balance LEDs left or right of center remain illuminated after the adjustment. See Balance Keys (4F), on page 12.
Next, check the input cables. Locate the channel of the system that appears to have less gain.
Switch that channel’s input cables. If the problem
now appears in the other channel, the cable is
defective. If the problem remains in the original
channel, check the KAV-300r output Cables
using the ’same procedure. If the difference in
gain is not cable related, call your authorized
Krell dealer, distributor, or Krell.
Q. When I use my surround sound processor,
where should I set the volume on the KAV-300r?
A. The volume level control on the KAV-300r is
not active in Theater Throughput mode. When
using the KAV-300r Theater Throughput feature,
system volume control is regulated by your sur-
round sound processor. See. Configuring the
KAV-3OOr for Theater Throughput, on page
18.
