Trinity inches forward

Read Now
 
I started designing my masterpiece to be in September of 2015.  Its now April of 2018 and she's still not ready.  I've been very close to having it complete for a few months now.  I've logged thousands of studio hours with my pair of prototype units.  There have been some issues with the onboard power supply getting too hot during long sessions, causing some components to fail.  I was able to resolve that issue, but they still run hot.  A couple weeks ago I took it upon myself to learn the workings of LTspice IV, a computer program designed to run accurate simulations of complex circuits.  In the past week I worked nearly 50 hours in LTspice running simulations of the current Trinity circuitry and then designing an improved version.  In the program it now seems to be quite impressive in terms of performance and stability.  The phantom power section is now capable of delivering a regulated low noise 48v at 250mA, more than most microphones will ever need.  I also discovered that the frequency response of Trinity is not as flat as I thought at the sub bass end of the audio spectrum.  Turns out the program is more accurate than my test gear.  Looks like at 20Hz there was a drop off of about 0.7dB when compared to 100Hz.  Not a lot at all, but there was also a phase shift that occurred right at 20Hz.  I was able to get that drop at 20Hz to be 0.04dB with the phase shift happening at 10Hz (inaudible).  These subtleties would have been next to impossible to see or correct without this program.  Seems like a great move on my part to figure it out.  I feel a lot more comfortable moving on to the next step in the development of Trinity.  It will take some additional capital to move forward, but the next step will be putting together the first production model.
