Post Subject: Old problem now forgotenPosted by Jorge on: 1/5/2012

A long time ago, when EAD dsp 9000 pro came out, Wadia had a DAC with volume control I dont remeber the number right now but -i think it was the 2000 anyway, the big deal about the EAD 9000 was that the integrated volume control was only 6db in the digital domain and the rest with high quality vishay resistors, so disregard the volume your were using, the minum "damage" to the signal was always constant.
I had the EAD 7000 and later upgraded to the 9000, evetually I kept the 7000 and sold the 9000....

Here is an explation from someone on the web I dont know:

"Do you know binary?

If not disregard the rest of this message.

If so that all this really is.

Say for example 65,535 is as loud as a signal can get... 0 is as quiet as it can get.

Pick any number between 0 and 65,535 and write it in binary. As you choose lower numbers (aka lowering the signal level) and write that in binary you will find it takes less bits to reproduce those numbers in binary. IOW, the lower signal is using less bits.

65,535 is 1111111111111111 in binary... IOW 16 bits of data.

20,000 for example is represented by 15 bits..
10,000 needs 14 bits
3,000 needs 12 bits
etc...etc..."
