The Master Reference Subwoofer is equipped with left and right CAST by-pass outputs, for connection to the CAST inputs of another Master Reference Subwoofer.

24 Left and Right Balanced By-pass Outputs

The Master Reference Subwoofer is equipped with left and right balanced by-pass outputs, for connection to the balanced inputs of another Master Reference Subwoofer.

25 Left and Right Single-ended By-pass Outputs

The Master Reference Subwoofer is equipped with left and right single-ended by-pass outputs, for connection to the single-ended inputs of another Master Reference Subwoofer.

Note

You can connect to any input (CAST, balanced, or single-ended) and output at any high-pass output. All high-pass outputs are active at once. For example, a signal from a source con- nected to the Master Reference Subwoofer through a CAST input can be output as CAST, balanced, and single-ended.

While you can connect at any input, you can output only at one by-pass output. By-pass outputs are active only one-at-a-time. For example, the CAST input is available only at the CAST by-pass output. The balanced input is available only at the balanced by-pass output. The single-ended input is available only at the single-ended by-pass output.
