are some new updated photos of Sjoko's studio
Room Rear Wall
is a small picture, looking from the tracking room up to the
stairs and the control room beyond.
this one is the other way around, looking from the stairs
down into the far corner of the tracking room.
On the left is the iso booth, which is all rendered and has
a dish-shaped roof to act with the room acoustics, which are
as smooth as butter.
On the right you see one side of the drum booth. A 1/2 round
dome shaped roof, which functions as a LF trap. On the inside
the roof has a combination of panel and round hole traps,
about 3'6" deep. The 4'6" x 8'6" roof in front
of that is hinged - it can go way up or way down. This allows
you to milk close with superb diffusion, without a build-up
of any unwanted frequencies. Moving the roof down makes it
all closer and tighter, the more you move it up the bigger
the sound gets.
You can just see the top corner of the baffle right bottom.
is a JBL promo pic. The speakers are JBL LSR 28P's with the
LSP 12P sub.
(John) have been looking for speakers for Guruland so I asked
Sjoko about the JBL Speakers. this was his reply:
took part in a test where a song was send to 10 mastering
places in the US, including most of the top houses.
I was the outsider, the only dual function recording / mastering
place, without a long track record for the facility itself.
I came second, beaten only by the mastering lab (they really
did a great job). I know its a combination of experience,
room design and gear, but no way would I have been close without
- They are consistant at all volumes. Very loud if you want
them to be, but volume does not color them.
- Of all such monitors, most likely the best priced, deu to
JBL's volume and their popularity.
(John) was approached by Sjoko to help him with a baffle to
place in front of the drum kit to stop the kick getting out
into the main room I replied with a drawing of my recommendation
also suggested some alternative ways of doing it:
ended up using the angled idea but made it a curve. here are
his reply comments:
again thanks for the drawings for the baffle. I made it as
per your drawing, the only thing I changed was the center,
which I made out of 1/4" finishing ply, fitted inside
the frame with an 8" deep curve.
VERY interesting result, as you might imagine. One side has
8"depth in the center tapering off to almost nothing
on the sides, the other side is the opposite. Placed in front
of a drum kit it is amazing to hear the different characteristics
this baffle creates. Very successfull.
