the insides, install power transformer
and TRS jacks.
the daughterboard containing the
selector switches for the RATIO,
Attack, and Release switches.
the balanced input and output TRS
jacks. Also preparing to wire the
toroidal power transformer.
Tidy and clean.
built a 2nd SSL unit. They're too good not to build.
holes and cuttng square holes for the front and back
the guts of the SSL compressor. Connect the meters,
knobs, switches, LED lights, jacks, fuse holders,
AC receptacles, etc...
SSL#1 and SSL#2. Guess which one is which???? I used
a digital caliper to make sure the locations of the
holes on the 2nd unit matches the locations on my
first unit. Measure twice, drill once.
audio clips. I did some rough testing using an oscilloscope.
It's nice to "see" how compression works.
Depending on the setting of the Ratio, Attack and
Release, you can see how further increasing the input
signal shows only a slight increase in the output
signal at some threshold level. Also, varying the
gain of the input signal, you can see how slow or
fast the output signal "follows" the input
signal, and how "slow or fast" it reacts.
to 15sec : Uncompressed
to 28sec: Compressed
to end: Uncompressed
that the "compressed"
clip sounds thicker and bigger than the uncompressed
The unit works, and it sounds great too.
