VU meter

Hi Sebatron ,
I have a post in Pro Audio forum. Some models have optional VU meters, and others do not have like 4000e. It is an quite expensive adds-on. :lol:
What is your opinion? Can a Sebatron be possibly damaged without a VU meter? is VU meter in the signal chain? that may affect signal in any way? :roll:
Thanks.

The VU meter

I have just begun my venture into the recording world and have many questions without answers. First and foremost could someone explain the reasoning behind the VU meter that reads in negative decibels? I understand the concept of decibels as being a logarithmic scale to simplify the hearing process but why use a negative scale in recording . . . am I missing something?

VU meters & buffer amps?

Can anyone recommend a good resource on the need to provide buffer amps (or "make-up gain") when connecting a VU meter somewhere along an audio signal path? To the ignorant among us (me), it all seems so arbitrary; in some cases a VU meter appears to be just hung off existing circuitry. In other cases, a single VU meter is fed by a huge "buffer amp module" that serves no other purpose.
