Operation

This section explains how to manually power on your system and subwoofer for operation and explains the importance of powering on in the appropriate order.

After the subwoofer is connected with your system, you can power on the subwoofer for operation. The order in which you power on your system is critical. To avoid the possibility of system-damaging transients, always turn on sources first, followed by preamplifiers/processors, the amplifiers, and finally the Master Reference Subwoofer.

The Steps for Subwoofer Operation follow:

1.Power on your source components (for example, CD, DVD).

2.Power on the preamplifier and surround processor.

3.Power on your amplifiers.

4.Move the power switch (6) on the back panel of the Master Reference Subwoofer to the up position. You will hear a series of clicks. The red stand-by LED (3) on the front panel illuminates.

5.Press the power button (1) on the front panel or the power key (26) on the remote control to switch between the stand-by and the operational mode. The blue power LED (2) illuminates. The subwoofer is now ready to play music.

6.To return to the stand-by mode, press the power button again. The red stand-by LED illuminates.

Krell recommends leaving the Master Reference Subwoofers in the stand-by mode between listening sessions.

Note

See Krell Link, on pages 44-45, for information on operating the Master Reference Subwoofer using Krell Link.
