RD0169 (A) KF730 & SB730 OWNER’S MANUAL Page 13 of 285.8.2 SB730 ConnectionsThere are three Neutrik NL4MP and one NL8MP connectors on the rear of each SB730. Theconnectors mate, respectively, with Neutrik NL4FC and NL8FC in-line cable connectors.SUB INPUT/OUTPUT NL4MP (each of two)PIN 1- SB730 SUB 1-PIN 1+ SB730 SUB 1+PIN 2- SB730 SUB 2-PIN 2+ SB730 SUB 2+1. Use as the input to the SB730.2. Use the second connector to loop SUB signals to additional SB730s.5.8.3 SB730 System Input ConnectionsThe NL8MP connector on the SB730s can be used as the input for an entire array. Using theSB730 SYSTEM INPUT on one SB730, an NL8 cable carries all amplified signals from the array’samplifiers to this SB730. Using NL4 cabling from this SB730, you can loop up to eight KF730sand three additional SB730s. With the maximum combination, the nominal load for each of thefour amplified signals is 2 ohms.SYSTEM INPUT NL8MPPIN 1- SB730 SUB 1-PIN 1+ SB730 SUB 1+PIN 2- SB730 SUB 2-PIN 2+ SB730 SUB 2+PIN 3- KF730 LF-PIN 3+ KF730 LF+PIN 4- KF730 MF/HF-PIN 4+ KF730 MF/HF+1. Connect the four different amplified signals needed to power a complete array of KF730s andSB730s to the SYSTEM INPUT.2. Use the KF730 OUTPUT to loop the LF and MF/HF signals to the KF730s using NL4 cabling.3. Use the SUB INPUT/OUTPUT to loop the Sub signals to the next SB730 using NL4 cabling.4. Daisy-chain additional SB730s in a similar fashion.KF730 OUTPUT NL4MPPIN 1- KF730 LF-PIN 1+ KF730 LF+PIN 2- KF730 MF/HF-PIN 2+ KF730 MF/HF+1.
