Krell KRC-HR

Ok I feel dumb just set up my system a krell krc-hr and ksa200s amp. the remote works for amp power and preamp functions except how do i turn off the power??
You don't on the preamp.
KRC-HR is designed to run 24x7. Ventilate it well, it runs hot (I used to own one).
If you have any questions or issues with your Krell gear, feel free to contact me. I have over 20 years experience repairing Krell, and other high-end audio.
