Simple Volume Control

Hi all,
I dont need a pre amp or any input selector just some thing to put between my CD player and my 300B mono blocs to give me a volume control. My speakers are very sensitive and when connected directly to the amps are wayway ( I mean WAY!! ) too loud. A pot in a box with input and output. I know there are the passive pre`s but can it be simpler ?
Regards
Tony

 

I use one of these for volume control in one of my systems. There are other cheaper pots. Just get a small aluminium box from Maplins, 2 pairs of RCA sockets and some cable should be all you need.

 

Thanks for the info, thats just what I`m thinking of, I have had a look here and wondered what value would be best.

I think that depends on the input impedence of the power amp. I tried a passive pre with 200k which didn't work too well with my amp and I just happen to have the 50k DACT lying around, so I tried it and liked it.

 

For something cheaper to play with just to see how you get on why not an Alps pot.
Currently using a 100k between PC via a DAC into a Cyrus power amp.

Hi,
If you just want volume control and no source selection then you could try the Lightspeed:

uses light dependent resistors - seems to be a kind load for source - it's very good IMO

 

Have sent an email to "George" about this but no reply yet. Is there any more info out there on the web other than those 64 pages! some wiring details or parts info, its the matching of the parts that seems to be the hard part, so I may just do a simple attenuated pot for now, but all ideas welcome.

Tony

 

Think there's very little info on web - George hasn't got a website or anything. Several folks on the thread have built their own - matching is the tedious bit. Haven't compared it a simple attenuated pot. Good luck with search.

 

try the goldpoint sa-1

or

these are as simple as they come ...

I think it would be a shame not to have a source selector.

One day you might want a radio, or to put the dvd player through the hifi or something.

 

bottleneck, sorry for OT, but - congratulations on the jubilee number of posts (unless it's fake

 

lol...just noticed that!!

I officially, should 'get a life' ! lol

oh well, I'm a hifi nerd and my name is Chris..

Hi Titian,

I agree, they are great, but why 2? Are they mono?

I bought my stereo version from Lee to use with Ian's Leak (while it was on loan to me). When Ian took his amp back the DACT replaced the Dale Vishay attenuator in my Glasshouse pre in my second system. It was a big improvement IMV.

Hi Tony sorry you didn't get my email, this should give some more insight on this thread,
