Lightspeed Attenuator

 

An innovative approach to passive preamps

 

What makes the Lightspeed Attenuator sound so dynamic transparent and clean from top to bottom?

The best way to describe the Lightspeed Attenuator is that it is like just one fixed soldered resistor that is in the signal path between the source (cd) or phono stage, and the power amp.
This resistor is soldered in place and has no contact points that potentiometers pots (potentiometers) or switched resistor (dact type) or TVC (Transformer) volume controls have.
Now this resistor LDR (light dependant resistor) has the ability to change it's resistance according to how much light LED (light emitting diode) is shone on it, hence it can control the volume without any mechanical contacts needed in the signal path.

It is believed that any light weight contacts (switches and especially pots and their wipers) have a diode rectification effect on the AC music signal, trying to rectify it which is very bad.
The Lightspeed Attenuator (LDR) system totally addresses is diode rectification effect. This is why it is so transparent and totally honest to the source, not adding any colorations or distortions to the source, it is just like being able to plug your cd players fixed output directly into your poweramp yet having control over the volume.
Ever wonder why when after having cleaned your RCA plugs and sockets on your interconnects, your system always sounds better. This is a similar type of contact albeit a much better one than the feather weight one inside a pot and the wiper contact of a switched resistor type control, because an RCA has a much larger and stronger pressure contact area, but still benefits by keeping it clean.
I hope this has given you a bit more insight to the Lightspeed Attenuator and it's revolutionary way of controlling volume, you can read a great deal more about it and it's history here. It's 250 pages over 2400 posts, but interesting. http://www.diyaudio.com/forums/showthread.php?t
