Krell S-275

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 S-275 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 S-275 and all system
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 amplifier’s
left and right loudspeaker output terminals for stereo operation
or positive and negative for mono operation (10).
The S-275 is equipped with standard binding posts for each
amplifier channel. These connectors accept bare wire, pins,
banana plugs, or spade lugs. Use the red terminal for the posi-
tive connection and the black terminal for the negative connec-
tion. When in monaural mode, use the left channel’s red connec-
tionfor poitive and the right channel’s red connection for nega-
tive.
4. Connect the output(s) of your preamplifier/processor to the
appropriate input(s) (6,7) on the S-275.
The S-275 is equipped with one pair of balanced inputs via
XLR connectors and one pair of single ended inputs via RCA
connectors. Set the input switch (5) to the match the input con-
nection Use the left balanced or single ended input when in
mono mode
5. Plug the AC cord into the IEC connector (13) on the back
panel of the S-275. Plug the remaining end into the AC wall
receptacle. Press the Power Button on the rear panel, The red
stand-by indicator (2) illuminates.
