John Chapman does a number of resistive based remote units using logic and high quality relays to do the switching.

Why no remote controlled discrete resistor volume?
I don't get it. It seems that Alps have the remote volume control market cornered. My understanding is that, in general, discrete resistor volume controls (stepped attenuators or relay activated resistors as used by NAT, AN Kits and others) are thought to provide the best sonics (detail, clarity, precision, etc.), followed by potentiometers and then chip controls. If this is true, why have none of the discrete resistor gang (Goldpoint, DACT, Seiden, TKD, etc.) come up with a direct competitor (or drop-in replacement) to the basic Alps remote motorized conductive plastic potentiometer volume control that can be purchased (motor and all) for about $35? These things show up in some highly reviewed preamps with prices approaching $10K and above. It just seems to me there should be better sonic options for remote controlled volume on preamps costing several thousand dollars and up. Why is it so hard to motorize a stepped attenuator? Just curious.

Motorizing a switched control can be a bit of a trick. You can have some torque to overcome, if the switch is worth a hoot. No way are you going to see this for $35.00! I've been watching the chip technology for 17 years now. The new ones are a lot better, but to this day if you have a state of the art preamp, those chips will shoot the preamp down before it can even get off the runway.... You did not mention relay operated controls but they are the next best thing to a motor turning a switch. So that makes the chip controls 4th on the list. Bent Audio is one of the better places to look if you want to do a remote properly. |
Blue Circle makes one as well. http://www.flickr.com/photos/17843311@N00/3768616815/in/set-72157619245521825/ |
