Connecting The Kav-250P; Additional Connections; Preamplifier And Remote Control Operation - Krell Industries Preamplifier KAV-250p Owner's Reference Manual

Connecting the KA V-250p
The left and right channel RCA and balanced
inputs and outputs are labeled on the back-
plate. Maintain the correct left/right orienta-
tion.
To prevent the introduction of hum or other
noise into the system, organize all wiring
between the KAV-250p and other system
components neatly. Separate AC wires from
audio cables.
1. Connect the left and right outputs of
your source components to the inputs
on the KAV-250p.
2. Connect the output of the KAV-250p to
the input of your power amplifier.
Krell ® recommends the use of balanced
interconnects. Balanced interconnects not
only have the ability to minimize sonic loss
but also have immunity to induced noise,
especially for installations using long cable
lengths. Balanced connections have 6dB
more gain than single-ended connections.
When level matching is critical, keep this
specification in mind.
Additional Connections
RC-5 IN
This input accepts baseband RC-5 input
commands from various remote devices,
facilitating custom installations. The input
allows the KAV-250p to be controlled via
hard-wired signals sent from such units.
12 VDC REMOTE POWER OUT
These outputs send 12 volt power on/off
signals to other Krell components, as well
as to other devices that incorporate a 12
volt power on/off trigger input. This allows
for remote turn on/off of other components
when the KAV-250p is powered on/off.
NOTE: Consult the owner's reference of
any device used in a custom installation to
take full advantage of the remote capability
of the KA V-250p.
Preamplifier and Remote
Control Operation
The KAV-250p provides input selection and
volume control from the front panel. The
KAV-250p remote provides complete pre-
amplifier functions as well as Krell CD trans-
port and power amplifier remote functions.
NOTE: Not all buttons on the remote control
function with the KAV-250p. Press the
Amp/Pre button on the remote to access
preamplifier commands.
NOTE: When a function button on the
remote control is pressed, the blue pilot led
will flash on the KAV-250p. When the but-
ton is released the flashing stops.
1. Engage the power switch on the
KAV-250p either manually or using the
remote control. After pressing the power
switch, the red Stand-by led on the
KAV-250p will turn off and the blue
Power led on the KAV-250p will illumi-
nate. The preamplifier is now ready for
operation.
2. Choose a listening source and select
that input either manually or via the
remote control.
3. Start play of the source.
4. Set the volume to a comfortable listen-
ing level.
5. When changing sources, lower the vol-
ume to the Off position or Mute the out-
put (see Mute, on page 6). This insures
