I agree with Tony
Fullvolume,
You can hook up both the single ended (RCA) and balanced (XLR) inputs on the 7BSST2; however, you will have to use the switch on the back of the 7BSST2 to select which input you want to use. Both inputs are not active at the same time.

See the manual for 7Bsst page 2
1. Input Select Switch.
Each SST channel gives the user the option of switching between either balanced input or single ended input.
2. Balanced Input connector. ( Imp. 20k )
This input connector accepts standard ‘XLR’ or 1/4” TRS .
Use quality, 100% shielded cables with gold plated connectors.
3. Single Ended Input. ( Un-balanced input ) ( Imp. 50k )
This input connector accepts standard ‘RCA’ or ‘Phono’ connectors.
Use quality, 100% shielded cables with gold plated connectors.
Balanced input Vs Single ended input:The balanced input requires a balanced pre-amp source. Balanced systems provide noise rejection from externalelectrical interference, so cable length can be very long ( 50m or longer ).The single ended or unbalanced input is provided for pre-amps without balanced output. Single-ended cables should be kept to 20’ (7m) or less. In general never use longer cables than necessary, never coil excess cable length, and keep signal wires away from AC power or speaker cables.
