rack wiring: 8-pin mini DIN angst

By Han-earl Park | Published: October 22, 2008

Almost completed the wiring of the rack (except the patch panel foot switch connectors which I am leaving for the moment). No problem with the XLR connectors, quarter inch phones, MIDI cables, barrel connectors… then I hit a major snag with the 8-pin mini DIN panel socket for the Mac serial connector. Too small, too [...]

enclosures: patch panel

By Han-earl Park | Published: September 19, 2008

One of the, again, less glamorous, but practical elements of io 0.0.1 beta++ is the patch panel. The panel holds the connectors that need to be accessed frequently (with the exception of the audio inputs to the pitch-to-MIDI converters since they already reside on the front panels). The connectors are, from left to right, IEC [...]

enclosures: pre-amp and power supply panels (physical artifacts)

By Han-earl Park | Published: September 18, 2008

As an update to the previous post, here’re photos of the machined and loaded panels. The front panel holds, from left to right, the power switch, 4 LED indicators (+15V, +12V, -12V and +9V), two filter bypass switches and two output level pots. The rear panel holds, from left to right, stereo audio inputs (unbalanced), [...]

enclosures: pre-amp and power supply panels

By Han-earl Park | Published: September 16, 2008

One handy box that forms a crucial (if unglamorous) part of io 0.0.1 beta++ contains the audio preamp (basically, a couple of filters, signal amplifiers and a balanced line driver) and power supply/distribution components (9V, ±12V). I don’t have a name for this box yet, but here are the layouts for the front and rear [...]
