How can I limit the volume on integrated amp

for you, for a few weeks a year, think that thru.

a closet with a lock, a critical piece of your good system locked in there so it cannot be used. note that it is disabled so they don't try to get it working (I would).

a bluetooth speaker they can link to, not too loud.

renters can turn the tv up enough, run pandora, link phones, so leave a note asking them not to exceed _____# on the tv set volume.
