Krell Industries MASTER REFERENCE SUBWOOFER manual Switching Between CAST and Balanced Inputs

(SECTION FOUR: Connections and Configurations continued)

Switching Between CAST and Balanced Inputs

The Master Reference Subwoofer offers a number of user-controlled options for choosing inputs and for switching from one input to another, using the remote control in conjunction with the menu option. See B. To Activate CAST Inputs, on page 34 for more information.

If you activate CAST or VOLTAGE in the menu, and have only one CAST or balanced source connected, the subwoofer automatically chooses the selected source and indicates the selection as either CAST or VOLTAGE in the front panel display (4).

If you activate CAST or VOLTAGE in the menu, and have a source connected to a CAST input (14) as well as a source connected to a balanced input (15), the subwoofer defaults to the CAST input.
