The rear-panel AUX IN L/L+R and R jacks accept input
from an external instrument or audio source, or the processed
signal returned from an external effect unit fed by the PSR-8000
LOOP SEND jacks, below. 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.

LOOP SEND L/L+R and R Jacks

These jacks deliver the output of the PSR-8000 for connec-
tion 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.

• 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 equip-
ment.
In this setup the sound of the PSR-8000 itself
as well as the external sources will be
reproduced via the PSR-8000 amplifier and
speakers, allowing the PSR-8000 to function
as a convenient stage monitor system.
