Stealth DC-1 - Anti-Mute

[mdrconsult]

OK, so this is weird!  I am listen to my DC-1 being driven by a Mac Mini running JRiver Media Center.  I never use the mute button, but today I got a call and thought I would just hit mute.  Well, much to my surprise the sound increased tremendously.  Not full volume but much higher than normal listening volume and certainly not the muting effect I was expecting.

Anyone else ever see/hear this before.  Any thoughts as to what it might be?  I'm hoping this isn't a "return it to be repaired" issue.  About a year ago I had to send it back to get the USB input fixed after it crapped out.

Thanks in advance for any help you can provide.

Geebo explained this in another post

The DC-1 has a user adjustable mute level. So if you have that set at say -20 and you are listening at -25 the hitting the mute will cause the music to get louder.
From the manual:

SETUP: MUTE LEVEL
When you press the Mute button on the DC-1 remote control, the main and headphone
levels are changed to a fixed (configurable) mute level. This option lets you configure
that level.
Options are: Silent (the default), -20 dB, and -40 dB
Note: The mute function changes the output level to a fixed - preset - level
(the -20 and -40 dB settings are relative to full Volume), if you engage Mute
while playing the DC-1 at a very low level, the result may actually be an
increase in output level.

To set mute to Silent:

1) Press the Menu knob once; “SETUP” is displayed on the top line of the display.
2) Turn the knob until “MUTE LEVEL” is displayed on the bottom line of the display.
3) Press the knob; “MUTE LEVEL” is now displayed on the top line of the display.
4) Turn the knob until “SILENT” is displayed on the bottom line of the display.
5) Press the knob; a bright triangle appears to the left of “SILENT” indicating that it is
the active choice (if SILENT was already the active choice, then the bright triangle was
already next to it).
At this point we can either turn the knob until “RETURN” is displayed on bottom line
of the display, then press the knob again - which will bring us back to the main menu
level where we can select something else to change - or simply wait for the menu to
leave setup mode after a few seconds. From the main menu level, simply select “EXIT”
and press enter to leave the Setup Menu.

Well now, don't I feel like an idiot! That was quick and easy. I would have never thought of having "Mute" be anything other than, oh I don't know, MUTE!

Mine was set to -20dB. I have a near field listening setup with 200W amps driving my Sonus Faber monitors and at -20dB, it is loud.

Thank You for your quick and accurate response.
