3.Connect the cables from the left and right Krell CAST 4-pin inputs (14) on the back panel to the left and right main preamplifier or processor outputs. For bal- anced or single-ended operation, connect the interconnect cables from either the left and right balanced (15) or the single-ended inputs (16) on the Master Reference Subwoofer back panel to your left and right preamplifier or processor outputs.

4.Connect the cable from the Krell CAST 4-pin LFE input (17) on the back panel to the sub(woofer) output of your processor. For balanced or single-ended operation, connect the interconnect cables from either the balanced LFE input

(18)or the single-ended LFE input (19) on the subwoofer back panel to the sub(woofer) output of your processor.

5.Connect the cables from the left and right Krell CAST 4-pin high-pass outputs

(20)on the back panel to the left and right CAST-equipped inputs of your power amplifier. For balanced or single-ended operation, connect the interconnect cables from either the left and right balanced high-pass outputs (21) or the left and right single-ended high-pass outputs (22) on the back panel to the left and right balanced or single-ended inputs of your power amplifier.

Notes

The Master Reference Subwoofer allows the connection of two independent preamplifier/source components to the CAST and either the balanced or the single-ended inputs. For example, you may want to connect two discrete front-end systems: Use the CAST input as the connection to a dedicated two-channel system in which the KPS 25sc Krell Playback System is the CAST source. Use the balanced input as the connection to a home theater system.

You cannot connect the balanced input and the single-ended input at the same time.

6.If you have more than one subwoofer, connect the cables from the left and right Krell CAST 4-pin by-pass outputs (23) on the back panel to the left and right CAST-equipped inputs on another subwoofer. For balanced or single- ended operation, connect the interconnect cables from either the left and right balanced by-pass outputs (24) or the left and right single-ended by-pass outputs (25) on the back panel to the left and right balanced or single-ended inputs of another subwoofer.
