SOLD OUT
::: DESCRIPTION :::::::::::::::::::::::::::::::::::::::::::::::::::::
this is a compact four channel passive analog
mono mixer with mutes and volume controls for each
channel along with a master volume control. it can
be used to process either audio or control voltages
and it can be used backwards as a splitter. being a
passive design means that it does not impart any "color" or
filtering of any kind and yes
you can use this as an analog summing buss with your
computer or other setup. it is the same design used in devices costing
10 times as much. being passive also means that it
doesn't require a power source but because of that
it may require a slight amplification after the main
output to bring it back to up the desired level, measuring
it during line level audio use showed a
nearly 20db drop in volume, this new version [ v.b ] has less of a drop then the first, and no the mutes do not pop when used. there
are different colored TSP stencils
used and they are usually a little slapdash. cases are powder coated black
