In Reply to: RE: buffered tape output option? posted by M3 lover on May 08, 2016 at 09:10:11
Some preamps simply connect the tape output directly to the source component similar to using a Y-adapter. A buffered tape output places an amplifier stage in-between the source and the tape output so there can be no electrical interference to the source component from anything connected to the tape output.

Shouldn't the buffer be ZERO gain?

> Shouldn't the buffer be ZERO gain?
No! It should be unity gain. However, I think that's probably what you meant.
Unity gain equals a gain of 1, which also equals a gain of 0-dB.
Yes, by zero I meant whatever comes IN goes OUT unchanged.
IE: 'The buffer should have NO gain'.
'Unity' is one of those Technical Terms, isn't it?
Too much is never enough
I don't know if "unity" is a technical term or not. It simply means "1." A buffer amplifier with a gain of "1" provides no amplification and whatever comes IN goes OUT unchanged. It is the same as a gain of zero-decibels, which is definitely a technical term.
Just having a grin.
But seriously,
The ONE thing about a unity gain device is that you KNOW if it does or does NOT invert polarity.
That might make a difference.
