Krell KAV–280p 15
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–280p to your system.
1. Make sure all power sources and components are off before
connecting inputs and outputs.
2. Neatly organize the wiring between the KAV–280p 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 outputs of your source components to the inputs
on the KAV–280p.
The KAV–280p has one pair of balanced outputs via XLR con-
nectors and one pair of single-ended outputs via RCA connec-
tors. Both balanced and single-ended outputs are active at all
times, allowing simultaneous connections to separate ampli-
fiers or separate systems.
Do not connect both outputs to a single stereo amplifier at one time.
4. Connect the outputs of the KAV–280p to the inputs of your power
amplifier.
The KAV–280p is equipped with one balanced input via XLR
connectors (B-1), three single-ended inputs via RCA connectors
(S-1, S-2, and S-3), and one tape input via RCA connectors.
The B-1, S-1, S-2, and S-3 inputs can be configured for Theater
Throughput. See Configuring the KAV–280p for Theater
Throughput, on page 19.
5. Plug the AC cord into the IEC connector (21) on the back
panel of the KAV–280p. Plug the remaining end into the AC
wall receptacle. The red stand-by LED (3) illuminates, and the
front panel display will flash “
– – –
” for 10 seconds. When the
display stops flashing, the preamplifier is ready to use.
