Connecting the KAV–400xito 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.

Steps

Pin assignments for the XLR connectors

Follow these steps to connect the KAV–400xi 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–400xi 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 (14).

The KAV–400xi 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 (15, 16, 17) on the KAV–400xi.

The KAV–400xi is equipped with one balanced input (B-1), three single-ended inputs (S-1, S-2, or S-3), and one tape input. The B-1, S-1, S-2, and S-3 inputs can be configured for Theater Throughput. See Optional Configurations, on page 17 for information on configuring an input for Theater Throughput.

5.Use the preamp outputs (19) to connect to an additional power amplifier, for loudspeakers in another room.

6.Plug the AC cord into the IEC connector (22) on the back panel of the KAV–400xi. Plug the remaining end into the AC wall receptacle. The red stand-by LED (3) illuminates. There is no audible click or delay.
