4. Setup
4.1 Placement
Place the SANSUI V11 on a flat, stable surface near your existing audio system. Ensure there is sufficient space around the unit for proper ventilation (at least 10cm on all sides and top).
4.2 Connecting Audio Components
- Connect Audio Sources: Use RCA cables to connect your audio sources (e.g., CD player, LD player, VCR) to the corresponding input jacks on the rear panel of the SANSUI V11.
- Connect to Amplifier: Use RCA cables to connect the main audio output jacks of the SANSUI V11 to an available input on your 2-channel amplifier.
- Connect Center and Surround Speakers: Connect your center and surround speakers to the pin jack speaker output terminals on the SANSUI V11. If your speakers use standard bare wire connections, you may need pin-to-bare-wire adapters or to modify the speaker wires with pin connectors. Ensure correct polarity (+ to + and - to -).
- Connect Subwoofer (Optional): If using an active subwoofer, connect its input to the SUBWOOFER OUT jack on the SANSUI V11 using an RCA cable.
- System Cable Connection (for compatible SANSUI/BOSE amplifiers): If your amplifier is a compatible SANSUI R11/A-α7/A-α9 or BOSE RA8, connect the system control terminal on the SANSUI V11 to the corresponding terminal on your amplifier using the dedicated system cable. This enables synchronized volume control.
4.3 Power Connection
After all audio connections are made, connect the supplied AC power cord to the AC power inlet on the rear of the SANSUI V11, and then plug the other end into a standard AC 100V, 50/60Hz wall outlet.
5. Operating Instructions
