If you havn't used it at all or excersized the controls, it may just need cleaning.

The volume control is just dirty.
If your are not handy with stuff, ask a techi friend to clean the volume control. Radio Shack would have a spray cleaner if yours is suitable for that sort of cleaner.
A long time to sit and get grunge on it.
A faster way to partially clean it is to turn it off, then rotate the control gently from minimum to maximum like two hundred times. That should get rid of the pops, and some of the grung, but it really does need to be cleaned inside.
HI TO ALL AGAIN.
Today I called AUDIO RESEARCH and spoke to guy name LENARD there who says that it sounds like the unit is in auto mute or something like that,and that I should try to get it off that mode by connecting it straight to the wall outlet and not to the power bar with the rest of components like I did.
My power bar is just a plain generic MAX 6 by PANAMAX.
He also mentioned something about electrolytic capacitors might be low,but he wants me to try above remedy first.
He did not encourage me in any way to ship unit in to them for inspection. Dirty volume control pot issue crossed my minf too,Elizabeth, and I happen to have some GAIG contact cleaner ,should I spray a little of that cleaner on my LS3B
controls or is is a bad idea.
My connections are as follows.
Krell md-1 transport feeding an Audio Research dac-3 with toslink optical cable. Then from dac-3 RCA outputs with kimber cable feed ARC LS3B linestage using the direct inputs.
After that I am using audioquest cables from LS3B main RCA outputs to the CONRAD JOHNSON MV55 TUBED power amp inputs.
Everything shares AC with PANAMAX MAX 6 power bar.
Please let me know your comments and advice .
Auto mute is self created by the equipment as a protection at turn-on. It SHOULD drop off as soon as the equipment is stabilized... maybe it is a relay? and is sticky? (My friends Marantz has such and it IS a mechanical relay in hers)
Definitly would cause low sound problems.
As to using the contact cleaner, You should ask Audio Research if it is safe to use.
Some controls are wire, and some are a film. I do not know about cleaning a film type pot. The wirewound or descrete resistors are fine to clean with a contact cleaner.
The relay is also very likely, as my friends Marantz would make nasty crackling noises till we cleaned the relay contacts.
ELGORDO I had to use a toslink out of necessity ,but I did order and waiting for delivery of Illuminati D-60 1m RCA to RCA DIGITAL cable and a 1.5m of Kimber Hero interconnects
,they should be in anyday now.My optical cable is bad and I am aware of it,it's a SAEC brand.
ELIZABETH I tried Audio Reasearch recommendations but it didn't change a thing. Also I did rotate volume control like around 80 times but nothing.So I called LENARD back at ARC and he now wants me to take it to my dealer so they can take a look at it.They adviced me against any contact sprays.I am kind of pissed off because it broke at the wrong time and by,itself.
thank you all.
I have An LS3, when I first turn on the unit the Mute light is dim lit for about 3 sec then goes bright.Does your unit do that? It sure sounds like your not patched in correctly.It sounds like cross talk within the unit,you know,if your not using the [direct input jacks] and say for instance your were patched into the CD input but had your mode selector switch on AUX, ect.The volume control will acts like you have discribed.
Just a note you can use a regular patch cord from your transport to your DAC, it just won`t have the Bandwith as the Digitl cable.It probably would still sound better than the glass you were using.My first reply to your problem I said [Mode switch] I ment [In put switch].Are you sure you were ported in the Direct in? Had the toggle switch in the dirrect position?
I will describe to you how my LS3B looks front and back.
Front ...Balance control in the middle..Mode in stereo..
Input cd.. power on..operate..direct..source..
Back ...using direct inputs..outputs I am using the one set of RCA outputs .
This is how its set and produces the above problems.
Can you see a problem in connections or otherwise. I will probably take it for service on coming friday. But I sure feel bad ,and somewhat changed my opinion on ARC gear.
I mean I own older less known , least expensive equipment that never failed,even after long time of not being used and all that.
I have a PROTON FM-AM table radio that bought in 1987 and use every blue moon(like once in two years)and the other day I listened to it,and it fired up like a rocket.
As good as the first day out of the box.Any ideas are welcome.
Thanks guys and gals
