Mark Levinson 380S

I'm sure I'm going to feel like an idiot when I get the answer, but here goes . . .

I just picked up a a 380S Preamp. I have chosen an input for my turntable and named that input PH 4. However, when I set Mode to Monitor, the display reads PH 4 OFF, and I am getting no signal. For the life of me, I can't figure out how to change this to PH 4 ON, or just PH 4. There is no mention of OFF being a setting in the Monitor mode. (FYI, the turntable is feeding into a ML PLS226 Power Supply & 25S Preamp, and the 380S is feeding a ML 333 Amp.)

Any ideas?

Have you tried just turning up the volume?

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?

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.
