INTRODUCTION
What is our
Multi Stereo Line Mixer ?
MSLM is a professional/line level device (+4dB) thought of as the ultimate solution for the “golden
rack era” lovers out there. It can be defined as a complete and very compact (only 1U rack high) overall
object or central piece of your entire rack system. It can do a lot for the managing of your signal.
It’s not new that, over the years, we’ve taken care of a lot of various systems. We started our entire
career by paying homage to the most iconic object of the ‘80s, the Tri Stereo Chorus, on which our
“The Wave – True Analog Multichorus” was based on. We spent countless hours testing and playing
that amazing jem and, of course, trying to understand the specific habitat that surrounded it.
Fast forward, after a few years of many rigs and many custom line mixers built, we focused our minds
in making an object that could resume the most requested features that many players asked us, and
try to pack all of them in 1U rack format.
We carefully looked at all the previous requests and tried to write down all the key features of the rack
systems we built, diving into three main “stages”.
THE CONCEPT
To properly understand how this system works (yep, this is not a simple mixer...it’s a lot more!), first of
all you need to understand how a guitar rack systems was intended to work.
Most of the time, the starting point was the pre-amplified guitar signal, or a slaved signal coming from
a loaded amplifier.
From here, people used to place an “audio looper” as the first object of the whole chain; this is a device
that could turn on/off serial processors such as equalizers, compressors, chorus, etc. More often, that
looper was also used as audio splitter, sending the signal into some other processors such as detuners,
delays, reverbs, etc.; instead of turning the output signals of those devices back into the looper, they
were sent into a mixer. This is what we usually call “parallel routing”.
The finishing touch, as some guys like Mike Landau and many others used to do, is to put other
processors in series after the mixing stage (i.e. PCM42s by Lexicon), in order to add another “color” to
the system.
Then, at the last stage, the stereo signal was amplified by a stereo power amplifier.
So, the average entire “classic” guitar rack system (so far) is always made at least by two pieces (but
usually more than two): a looper and a mixer. Just for the control part of the system, with very limited
routing possibilities indeed.
More often, those loopers and mixers were custom tailored to personal specifications and very few
were made for “generic” use; so, this kind of environment wasn’t so changed during the last 20 years
at least (or maybe more).
