J.Rowland Is it possible to shut off the display

No, you can neither shut off the display nor dim it, as far as I know. As for the
balance control, there is none. They are using the remote from a different
(earlier) product, one that did offer a balance control.

I defer to Drubin's response, as I have not used a Concerto. But I find it to be ironic that my JRDG Concentra allows the user to set the display so that it shuts off automatically a few seconds after a change is made. I like that system very much, and find it odd that they wouldn't have carried it through to the Concerto.

Tony, how do you do that on the Concentra? Also, don't you have balance control on the Concentra?

Part of the problem may be that JRDG never deigned to publish a manual for the Concerto.

Balance control works for me, I believe you have 6 clicks in either direction. The balance control never fully defeats either channel. I also wonder is it OK to leave amp always on?
