Mark Levinson 380S

Are you sure that your 380S has a built-in phonopreamp ?

Didn't work - looks like a service call. Thanks to all for your help!

On my unit if you turn the volume all the way down for any input the display indicates OFF (same is true when first turning it on).  Turning the volume up increases it.  If turning the volume up does not increase volume then you may have a software glitch.  Try rebooting the preamp (volume is under digital control).  If it still doesn't work you have some kind of hardware or software failure.

No, unfortunately.

It isn't RECD OFF that is the issue (which is indeed displayed when I go into Record Select Mode), but PH 4 OFF (which is displayed in Monitor Mode.)

Yes, I appreciate that, but was wondering whether the same basic sequence of button pushing might also toggle PH 4 ON and OFF.

Thanks, I do have the manual, but appreciate your link. However, this simply prevents the designated input from sending a signal to the recording outputs. This has nothing to do with sending the signal to the amp & speakers.

It isn't RECD OFF that is the issue (which is indeed displayed when I go into Record Select Mode), but PH 4 OFF (which is displayed in Monitor Mode.) As the instructions say, RECD OFF should be in effect if you simply wish to listen to a signal and not record it.

Presumably you have seen it, but if not, here’s a link to the manual:

The record outputs may be disconnected (or “defeated”) by pressing the input selector button of the currently selected (to-be-recorded) input a second time. Doing so will toggle the record outputs on and off. The display will alternatively read the name of the chosen input and RECD OFF as shown below.

Defeating the record outputs eliminates even the possibility that the input im- pedance of a recording device could have an effect on the sound quality of the preamplifier. We recommend that record outputs be turned OFF when not in use.

Certainly! There is no signal going to the amp, no noise of any sort. It seems to me that OFF means that the input is not inputting. How do I turn OFF off?

Have you tried just turning up the volume?
