Stereo Audio Platform Gain Controller
The SGC1 is one of our latest kits, and provides a great solution to
the age-old problem: how can we easily correct inconsistent audio levels without
negatively affecting the dynamics of the audio signal? The SGC1 circuit implements a principle
known as the "Platform Gain Principle," which was originally developed by CBS Labs to allow transmitted audio
levels to be automatically adjusted to keep them within a desired range.
Think of it like an audio engineer, constantly adjusting the output level in order to limit highs that would be too
loud while boosting lower levels so that they can still be heard. You may think "oh, this is just another
limiter/compressor!" Not so! Here's the real trick: keeping the full dynamic range ratio of the output signal the
same as the original input - something the typical limiter/compressor can only dream of doing! The SGC1 can be
placed in just about any standard analog stereo line level audio circuit to keep the audio level within the desired
range. It's also the perfect addition to any of our hobby kit transmitters, allowing you to match levels between
different audio sources while keeping lows audible and preventing the highs from overdriving.
In addition to its useful basic function and great audio performance, the SGC1 also boasts a front panel LED
meter to give an indication of the relative level of the input signal, as well as a front level control that allows you
to adjust the controller to the min/max center point of your desired level range. And yes, it is a Stereo Gain
Controller! Meaning that the levels of both the left and right channels are monitored and adjusted equally, thereby maintaining the relative virtual position of things like instruments, singers and speakers! The entire unit is
housed in a slim attractive black textured aluminum case that is sure to complement your studio or home theatre. If you're looking for perfect audio levels, hire a broadcast audio engineer, but if that doesn't fit your budget,
the SGC1 is the next best thing! Includes 15VDC world-wide power adapter.

Classic Nixie Tube Clocks
Our next generation of classic Nixie tube clocks perfectly mesh today's technology with the Nixie era technology of the 60's. Of course, features you'd expect
with a typical clock are all supported with the Nixie
clock... and a whole lot more! The clocks are programmable for 12 or 24 hour mode, various AM/PM
indications, programmable leading zero blanking, and
include a programmable alarm with snooze as well as
date display, 4 or 6 tube, kit or assembled!
We then jumped the technological time line of the
60's Nixie displays by adding the latest multi-colored
LEDs to the base of the Nixie tubes to provide hundreds of illumination colors to highlight the glass
tubes! The LED lighting can be programmed to any
color and brightness combination of the colors red,
green, or blue to suit your mood or environment.
Then we leaped over the technological time line by
integrating an optional GPS time base reference for
the ultimate in clock accuracy! The small optional GPS
receiver module is factory assembled and tested, and
plugs directly into the back of the clock to give your
Nixie clock accuracy you could only dream of! The
clocks are available in our signature hand rubbed Teak
& Maple or clear acrylic bases.
