Krell KAV–300iL
Introduction
Thank you for your purchase of the Krell KAV–300iL Remote
Control Integrated Amplifier. This fully integrated amplifier and pre-
amplifier has a fully balanced signal path from input to output and
employs a wide bandwidth design with low negative feedback for
sonic accuracy throughout the frequency spectrum. All circuits up
to the driver stage are pure Class A.
Krell’s new surface mount technology (SMT) means that the
KAV–300iL is an integrated amplifier with big power—200 Watts
per channel—that does not require big space. SMT allows individ-
ual circuit elements to be placed very close together. This shortens
signal paths and allows circuit elements to operate at the same
temperature, resulting in more accurate signal transfer and
enhanced reliablilty.
The KAV–300iL is easy to operate and integrate into your system.
The remote control accesses all amplifier functions, and remote
control connection options allow the KAV–300iL to be easily con-
nected with other components. The Theater Throughput feature
provides easy integration of the amplifier into a home theater
system.
This owner’s reference manual contains important information on
the placement, installation, and operation of the KAV–300iL.
Please read this information carefully. A thorough understanding of
these details will help ensure satisfactory operation and long life
for your KAV–300iL and related system components.

Definition of Terms
Following are the definitions of key terms used in your owner’s ref-
erence 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 integrated amplifier with no gain, for integrated vol-
ume and balance management of Krell home theater systems.
Balanced
INPUT AND OUTPUT
CONNECTIONS
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 instal-
lations, balanced connections have 6 dB more gain than single-
ended connections and allow the use of long interconnect cables.
Balanced connections are completely immune to induced noise
from the system or the environment.
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 recom-
mended for connections requiring long cable runs.
Off
OPERATION
The component is off when the AC power cord is unplugged from
the wall receptacle.
Stand-by Mode
A low power consumption status that keeps the audio circuits at
idle. When you plug the AC power cord into the wall receptacle,
the red stand-by LED illuminates. The component is now ready to
be switched to the operational mode. Krell recommends leaving
the component in the stand-by mode when it is not playing music.
Operational Mode
When the component is in the stand-by mode, and you press the
power button on the front panel or the power key on the remote
control, the blue power LED illuminates. The component is in the
operational mode and is ready to play music.

Krell KAV–300iL
Placement
Before you install the KAV–300iL into your system, review the fol-
lowing guidelines to choose the location for the KAV–300iL. This
will facilitate a clean, trouble-free installation. The KAV–300iL does
not require any type of special rack or cabinet for installation. For
the dimensions of the KAV–300iL, see Specifications, on the
back cover.
Place the KAV–300iL on a firm, level surface, away from excessive
heat, humidity, or moisture. The KAV–300iL requires at least two
inches (5 cm) of clearance on each side and at least two inches
(5 cm) of clearance above and below the component to provide
adequate ventilation. Installations inside cabinetry may need extra
ventilation.
The KAV–300iL is not hum-sensitive. Other components may be
placed on or around the KAV–300iL (make sure ventilation grids
remain unobstructed).
Place the amplifier as close to the loudspeakers as possible and
keep loudspeaker cable lengths to a minimum. Loudspeaker cable
adds impedance to the load the amplifier must drive, regardless of
the cable’s gauge. All Krell amplifiers drive the lowest impedances
with ease, but long loudspeaker cables reduce the maximum
power that can be delivered to the loudspeakers.
The KAV–300iL has superb regulation and does not require a ded-
icated AC circuit. Avoid connections 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 unit’s maximum
power consumption of 1800 Watts.
AC Power
Guidelines
The KAV–300iL 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–300iL.

Krell KAV–300iL
Connecting the KAV–300iL
to Your System
USING BALANCED
CONNECTIONS
Krell recommends using balanced interconnect cables. Balanced
interconnect cables not only can minimize sonic loss but are also
immune to induced noise, especially with installations using long
cables. Balanced connections have 6 dB more gain than single-
ended connections. When level matching is critical, keep this gain
value in mind.
Follow these steps to connect the KAV–300iL to your system.
Connection
Steps
1. Make sure all power sources and components are off before
connecting inputs and outputs.
2. Neatly organize the wiring between the KAV–300iL and all sys-
tem components. Separate AC wires from audio cables to
prevent hum or other unwanted noises from being introduced
into the system.
3. Connect the left and right loudspeaker cables to the integrated
amplifier’s left and right loudspeaker output terminals (12).
The KAV–300iL uses standard binding posts for each amplifier
channel. These connectors accept bare wire, pins, or spade
lugs. Use the red terminal for the positive connection and the
black terminal for the negative connection.
4. Connect the left and right outputs of your source components to
the appropriate analog inputs (13, 14) on the KAV–300iL.
The KAV–300iL is equipped with one balanced input (B-1), three
single-ended inputs (S-1, S-2, or S-3), and one tape input (15).
The B-1, S-1, S-2, and S-3 inputs can be configured for Theater
Throughput. See Optional Configurations, on page 18 for
information on configuring an input for Theater Throughput.
5. Use the preamp outputs (17) to connect to an additional power
amplifier, for loudspeakers in another room.
6. Plug the AC cord into the IEC connector (21) on the back panel
of the KAV–300iL. Plug the remaining end into the AC wall
receptacle. The red stand-by LED (3) illuminates. There is no
audible click or delay.

Operating Your KAV–300iL
This section provides information about operating the KAV–300iL.
The KAV–300iL provides basic input selection and volume control
operation from the front panel. The remote control includes addi-
tional preamplifier functions as well as CD transport and amplifier
controls. See Remote Control, on page 13, for more information.
After the KAV–300iL is connected to AC power and is in the
stand-by mode, use the power button (1) or key (24) to switch the
component to the operational mode. The blue power LED (2)
illuminates.
The KAV–300iL Remote Control Integrated Amplifier is easy to
operate. However, great care should be exercised when operating
a system that includes the KAV–300iL, because of the amplifier’s
power output. Switching between active sources without muting
the preamplifier output, or bumping/miscuing a device, can gener-
ate large transients at low frequencies. The KAV–300iL may gen-
erate enough power with these transients to damage most loud-
speakers. To avoid damage, be sure to switch all sources with the
preamplifier level either muted or fully attenuated. Do not change
inputs to the amplifier while the amplifier is on.
Amplifier
Operation
Note
Krell amplifiers have large reserves of clean power and can safely drive
loudspeakers to higher sound pressure levels than other amplifiers.
However, use care when setting high playback levels and lower the vol-
ume level at any sign of loudspeaker distress.
ON/OFF AND
STAND-BY OPERATION
When powering up any system, always turn amplifiers on last.
When powering down, always turn amplifiers off first.
1. When the amplifier is in stand-by mode, with the red stand-by
LED (3) illuminated, turn the amplifier on by pressing the
power button (1), or pressing the power key (24) on the remote
control. There is an audible click. The blue power LED (2) illu-
minates, and the red stand-by LED (3) turns off. The amplifier
is now ready for operation.
2. With the amplifier in the mute position, or the volume control
fully attenuated, select a source from the front panel (5) or
using the remote control (26). Start playing the source. Set the
volume to a comfortable listening level using the level up and
down buttons (10) or volume keys (29).

It is now safe to turn off the rest of the system.
The KAV–300iL has a discrete tape input and output. The tape
output is used to send an input signal from S-1, S-2, S-3, or B-1 to
a recording device or processor. You can use the tape feature in
three ways:
Tape Input and
Output
1. Use this button to playback pre-recorded tapes.
2. Use the tape input to compare the output signal of a three-
head analog tape recorder to the output signal of an audio
source, when making a recording. To activate this function,
select an audio source for recording using either the S-1, S-2,
S-3, or B-1 analog input buttons (5) or keys (26). Press the
tape button (6) or tape key (27) on the remote control to switch
between the tape recorder output (red tape monitor LED [7]
illuminated) and the input source (red tape monitor LED [7] not
illuminated).
3. Use the tape output to create a processor loop, when the
KAV–300iL is connected to a graphic equalizer or other ancil-
lary equipment. To activate this function, connect the equip-
ment to the KAV–300iL tape outputs (16) as described in the
equipment manufacturer’s manual. Press the tape button (6) or
key (27) on the remote control to switch between the proces-
sor output (red tape monitor LED [7] illuminated) and the input
source (red tape monitor LED [7] not illuminated).
When changing sources, lower the volume to off or mute the output. This
ensures that the next source played does not damage your system with
a high output transient.

Throughput
When you configure a KAV–300iL input for Theater Throughput,
the KAV–300iL volume and balance controls are transferred to the
audio/video surround sound processor, for integrated volume and
balance management as well as ease of operation. As long as the
KAV–300iL input is configured for Theater Throughput and con-
nected to the audio/video surround sound processor’s input config-
ured for Theater Throughput, all KAV-300iL volume and balance
adjustments are made through the surround sound processor.
When you disengage the KAV–300iL input from Theater
Throughput, the volume and balance controls revert to the
KAV–300iL.

How to Troubleshoot System Noise
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 loudspeakers. This sometimes occurs when
introducing a new component into a system.
If a low frequency hum emanates from the loudspeakers when you
place the KAV–300iL amplifier into the system, follow these simple
troubleshooting steps:
1. Check all cable terminations, making sure they have solid sol-
der joints and are of sound construction.
2. With the amplifier off, remove the interconnect cables, then
turn the amplifier on. If the hum disappears, turn the amplifier
off and reinsert one of the interconnect cables. Turn the
amplifier back on. If the hum reappears with one or both
cables reinserted, there may be a defective cable. Have the
interconnect cables checked before proceeding.
3. If the interconnect cables are sound, you may be experiencing
a ground loop. Please contact your authorized Krell dealer,
distributor, or Krell for suggestions on how to solve this
problem.

Krell KAV–300iL
Questions and Answers
Q. Should I leave my KAV–300iL on at all times?
A. Krell recommends leaving the amplifier in the stand-by mode,
ready to play music. If you are not going to play music for a
long time, you may disconnect the amplifier from AC power
supply.
Q. When I turn on the amplifier there is a loud hum through the
loudspeakers. What should I do?
A. When a new component is introduced into a system, a low
frequency hum may occur in one or both loudspeakers. Check
all input and output connections, making sure they are of
sound construction. See How to Troubleshoot System
Noise, on page 19. If the interconnects and cables are sound,
you may be experiencing a ground loop. This can often be
easily eliminated. Please contact your authorized Krell dealer,
distributor, or Krell for suggestions on how to solve this
problem.
Q. When I use the KAV–300iL’s Theater Throughput capability
with my surround sound processor, where should I set the
volume on the KAV–300iL?
A. You do not need to set the volume on the KAV–300iL because
the amplifier’s volume and balance controls are not active in
the Theater Throughput mode. When using the KAV–300iL’s
Theater Throughput capability, the surround sound processor
controls the system volume. See Optional Configurations, on
page 18.

Freight to the factory is your responsibility. Return freight within the United States (U.S.A.) is
included in the warranty. If you have purchased your Krell product outside the U.S.A. and
wish to have it serviced at the factory, all freight and associated charges to the factory are
your responsibility.
Krell 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 also your responsibility.
Krell is not responsible for any damage incurred in transit. Krell will file claims for damages
as necessary for units damaged in transit to the factory. You are responsible for filing claims
for shipping damages during the return shipment.
Krell does not supply replacement parts and/or products to the owner of the unit.
Replacement parts and/or products will be furnished only to the distributor performing
service on this unit on an exchange basis only; any parts and/or products returned to Krell
for exchange become the property of Krell.
No expressed or implied warranty is made for any Krell product damaged by accident,
abuse, misuse, natural or personal disaster, or unauthorized modification.
Any unauthorized voltage conversion, disassembly, component replacement, perfo-
ration of chassis, updates, or modifications performed to the unit will void the war-
ranty.
The operating voltage of this unit is determined by the factory and can only be changed by
an authorized Krell distributor or at the factory. The voltage for this product in the U.S.A.
cannot be changed until six months from the original purchase date.
In the event that Krell receives a product for warranty service that has been modified in any
way without Krell authorization, all warranties on that product will be void. The product will
be returned to original factory layout specifications at the owner’s expense before it is
repaired. All repairs required after the product has been returned to original factory specifi-
cations will be charged to the customer, at current parts and labor rates.
All operational features, functions, and specifications and policies are subject to change
