Configuring the KAV–400xi for Theater Throughput

HOW TO ACTIVATE AN INPUT FOR THEATER THROUGHPUT

IMPORTANT

To simplify the integration of an audio/video surround sound processor into your system, set any input on the KAV–400xi (S-1, S-2, S-3, or B-1) to operate as a unity gain stage. Krell calls this configuration Theater Throughput.

When you configure a KAV–400xi input for Theater Throughput, the KAV–400xi volume and balance controls are transferred to the audio/video surround sound processor, for integrated volume and balance management as well as ease of operation. As long as the KAV–400xi input is configured for Theater Throughput and con- nected to the audio/video surround sound processor’s input config- ured for Theater Throughput, all KAV–400xi volume and balance adjustments are made through the surround sound processor. When you disengage the KAV–400xi input from Theater Throughput, the volume and balance controls revert to the

KAV–400xi.

1.Turn on the KAV–400xi power.

2.Press and release the button on the front panel or the key on the remote (5) for the device you wish to configure for Theater Throughput. The LED illuminates.

3.Press the button or key again and hold it for four seconds. The front panel display (11) shows “thr.”

Make sure the level on the source component is set to zero when configuring the KAV– 400xi input set for Theater Throughput. Source components without level controls should not be connected to an input configured for Theater Throughput. Doing so can result in excessive and possibly damaging volume levels when the source is played. Always turn off the source component before you config- ure any input on the KAV– 400xi for Theater Throughput.

HOW TO DISENGAGE AN INPUT FOR THEATER THROUGHPUT

1.Turn on the KAV–400xi power.

2.Press and release the button on the front panel or the key on the remote (5) for the device you wish to disengage from Theater Throughput. The LED illuminates.

3.Press the button or key again and hold it for four seconds. The phrase "thr" disappears from the front panel display (11), indi- cating that Theater Throughput is disengaged.
