The signal received at the AUX IN/ LOOP RETURN jacks is mixed with PSR-8000 sound and delivered via the speaker system. Use the L/L+R jack only for monaural input. The TRIM control allows the input sensitivity of the AUX IN L/L+R and R (LOOP RETURN) jacks to be adjusted for optimum level matching with the connected equipment. AUX IN/LOOP RETURN R L / L + R MIN MAX TRIM • Never return the output from the AUX OUT jacks to the AUX IN jacks. Also never return the output from an external device fed by the AUX OUT jacks to the AUX IN jacks. Doing so can result in a feedback loop which damage the PSR-8000 and connected equipment.

Stereo Effect Processor Effector LOOP SEND L/L+R R LOOP RETURN L/L+R R 3 LOOP SEND L/L+R and R Jacks These jacks deliver the output of the PSR-8000 for connection to external signal processing devices such as reverb or equalizer units. The output from the signal processor can be returned to the AUX IN/LOOP RETURN jacks, described above. When feeding a monaural device connect only the L/ L+R jack. When a plug is inserted into the L/L+R jack only, the left- and right-channel signals are combined and delivered via the L/L+R jack. When a plug is inserted into the LOOP SEND L/L+ R jack the internal signal flow is interrupted and only the signal returned to the AUX IN (LOOP RETURN) jacks - see above - will appear at the PSR-8000 speakers, headphones, and AUX OUT jacks. No sound will be produced if the return signal is not fed to the AUX IN (LOOP RETURN) jacks. LOOP SEND R L/L+R 2.
