Placement
WARNING
The surround preamp/processor must not
be located where it could be exposed to dripping or splashin~luids.
IMPORTANT
The ventilation grids and cooling fan on the
top of the Audio + Video Standard need to
be unobstructed at all times during operation. Do not place flammable material on
top of or beneath the Audio + Video
Standard. For installations inside cabinet04,
make sure the Audio ÷ Video Standard has
adequate air circulation. Contact your dealer,
distributor or Krell~ for further information.
Before you install the Audio + Video
Standard. into your system, review the
following guidelines to choose the opti-
mum location for placement. This will
help ensure a clean, trouble-free installa-
tion. For the dimensions of the Audio +
Video Standard, see Specifications on
back cover.
Place the Audio + Video Standard surround
preamp/processor on a firm level surface
away from dirt or moisture. A minimum spacing of three inches must exist between the
Audio + Video Standard and surrounding
components to ensure proper ventilation.
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
induced into your playback system.
The Audio + Video Standard has superb regulation and does not require a dedicated AC
circuit. Avoid connections through extension
cords or multiple AC adapters. High quality,
15 ampere, grounded AC strips are accept-
able. High quality AC line conditioners or filters may be used if they are grounded.

1 Tape
A tape monitor al!~ws you to compare the
output from your a~log tape recorder to the
original source while making a recording.
After selecting a source for recording (B1,
$1-$5), press the tape button to toggle
between the tape recorder output (LED illu-
minated) and the input source (LED not illuminated).
2 Analog In
The Analog In button activates the analog
input and cycles .through the six analog
audio inputs. B1 is a balanced input via XLR
connectors. $1-$5 are single-ended inputs
via RCA connectors.
3 Digital In
The Digital In button activates the digital
input and cycles through the six digital audio
inputs (C1, C2, T1, T2, XLR, and RF). The
main display will show RF IN when the RF
input for Dolby Digital (AC-3) is selected.
5 Composite
The composite video input button cycles
through the four composite video inputs.
6 S-Video
The S-video input button cycles through the
four S-video inputs.
7 Volume Control Knob
The volume control knob adjusts the output
level for the entire system as well as individual levels for the center speaker, side speak-
ers, rear speakers, and subwoofers. The volume control knob normally adjusts the mas-
. ter volume as indicated by the LED illuminat-
ed above the master button (19). The
change in volume is indicated in the main
display and also on-screen. Adjustments to
the center speaker, side speakers, rear
speakers, and subwoofers are made by
pressing the corresponding individual chan-
nel volume buttons (20) and rotating the volume control knob to the desired setting. The
master volume control has a numerical
range from 0 to 152 with 89 being the Dolby
reference. The center speaker, side speakers, rear speakers, and subwoofer volume
trim have a range of __.12 dB.
C1 and C2 are coaxial inputs via RCA
connectors.
T1 and T2 are TosLink
XLR is an AES/EBU connection.
RF is available via RCA or BNC connectors. There is no front panel LED for this
digital input.

The main display provides status.messages
for a variety of Audio + Video Standard oper-
ations.

inputs.
8 Power Button
The powerbutton toggles the Audio + Video
Standard from standby to operate and also
switches the 12 VDC output between on and
off.
9 Power LED
The power LED illuminates when the. rear
panel main power switch [see Figure 2 (38)
on page 11] is placed in the on position.
During remote control operation, the power
LED will flash, indicating the Audio + Video
Standard is receiving remote control commands.
10-16 Audio Mode Buttons
The five buttons (10, 13, 14, 15, and 16)
select one of the Audio + Video Standard’s
audio modes.
The Audio + Vid~.o Standard automatically
selects which di~al decodingformat to use,
based on the input signal it receives.
When a silent digital signal .is present, the
Audio+Video Standard will automatically
mute its output until program material
resumes and the Audio+Video Standard
identifies the correct processing mode. This
occurs while changing laser, DVD or com-
pact discs, and between tracks on a cd.
Mute protects your syste ,m by preventing the
Audio + Video ~Standard from playing back
digital data in an incorrect format. If the Audio
+ Video Standard is going to be used as a
digital to analog converter for music playback, this muting may seem awkward
because the beginning of each track may be
affected. You can change the format auto-
sensing to eliminate this muting, if you wish.
To do so, switch the unit into standby. Press
the DTS button (13) on the front panel and
switch the Audio+Video Standard out of
standby to power on (operate). This will dis-
able the automatic muting feature of the
Audio+Video Standard and will alter the way
in which the automatic format sensing oper-
ates. For best results, select DTS prior to listening to any DTS encoded material and be
careful to select the proper format for each
piece of softWare played through the. digital
inputs.
To re-engage the automatic muting feature,
switch the Audio+Video Standard into standby and toggle the main power switch (38)
the rear panel to the off position. When. you
restart your Audio + Video Standard, the
automatic muting feature will be active. Be
sure to turn all amplifiers off when switching
the main power switch on and off.
10 Dolby Digital engages Dolby Digital
(AC-3) processing for use with Dolby
Digital (AC-3) encoded source material.
The Audio + Video Standard automati-
cally switches to Dolby Digital (AC-3) processing upon receiving a Dolby Digital
(AC-3) encoded signal. No user interven-
tion is required after the appropriate digital input is selected and connected.
Dolby Pro Logic engages Dolby Pro
Logic circuitry for use with all Dolby sur-
round processing encoded material. This
includes laser discs, videotapes, television broadcasts, and compact discs.
11 The Dolby Digital LED is lit and the
Dolby Pro Logic LED (12) is not lit when
the Audio+ Video Standard is in the
Dolby Digital (AC-3) decoding mode.
When both the Dolby Digital LED and the
Dolby Pro Logic LED are lit, the Audio +
Video Standard is decoding a Dolby
Digital (AC-3) encoded Dolby Pro Logic
signal.
12 The Dolby Pro Logic LED is lit and
the Dolby Digital LED (11) is not lit when
the Audio+ Video Standard is in the
Dolby Pro Logic decoding, mode. When
both the Dolby Digital LED and the Dolby
Pro Logic LED are lit, the Audio + Video
Standard is decoding a Dolby Digital
(AC-3).encoded Dolby Pro Logic Signal.
13 DTS engages DTS digital surround
processing for use with DTS encoded
source material. The Audio + Video
$tandard automatically switches to DTS
processing upon receiving a DTS signal.
No user intervention is required after the

recordings. This provides monaural out-
put from the ~nter speaker and sub-
woofer(s) only.~lf the system does not
include a center speaker, the monaural
signal is split between theleft and right
speakers.
16 Preamp disengages all surround
processing circuitry for use with stereo
recordings. When fed an analog source,
the Audio + Video Standard functions as
a pure Class Ai~ high resolution, analog
preamplifier. For digita, I sources, the
Audio + Vide£ Standard employs 24-bit,
custom KrelP-written, digital-to-analog
conversion software before being sent to
the analog preamplifier stage.
