We’ve missed this blog. We suspect you have too. And that’s why we are coming back.
2015 has been an interesting year. How do we mean that? We mean that in the sense of the Chinese curse “May you live in interesting times”.
We faced some unexpected delays with new products. We struggled with technological challenges. We battled Apple approvals.
Now that 2016 is upon us, we are determined to put all of that behind us and move on. We plan to return to regular updates about our projects on this blog.
With that said and to celebrate, we are announcing a sale on DACport HD, the newest version of our award-winning DACport:

I will be leaving to go to IBC in Amsterdam with 5 prototypes today. We have interest from the European broadcast community and I have a number of meetings scheduled with dealers and distributors.
I will be taking what we consider to be final units with me. These are the units we will start to send out this month and ramping up next month.
Stacie will be in touch with our customers to announce what we are shipping and when.
Update: We have assembled the new analog PCBs and are very happy with the performance. We have blessed the design for production.
I put the boards through their paces last week, recorded guitar, bass, microphones, played back, overdubbed, etc. All functions work well. Limiter works well. Recording and playback work well.
We will be showing the units at IBC in Amsterdam next weekend. We are ramping up production and will fulfill a small number of orders this month. More next month. This project is starting to see the light at the end of the tunnel and shipment is near!
Today we received the new analog PCBs from the manufacturer.
We are filling them with parts and will try to power them up tomorrow.
I’m really hoping that this Rev 10.9 is the last one. Everything works well, we made this spin just to clean up the tiny little audio buzz in the left channel, to make sure it’s super quiet. Will report on that soon.
Meantime, if you are heading out for the long weekend — please get to relax.
If you do, we will relax through you, vicariously
Several more tweaks and hopefully this one is it.
We have stuffed over 80dB of gain inside this little box and all that gain is sitting around TONS of digital circuits.
And we know that digital circuits are not a friend to analog circuits. They need to be separated as much as possible to avoid interference. Which separation is hard to achieve in small spaces.
Everything needs to be buttoned up to make sure audio is super-clean. This is a pro product after all! Hopefully, by now we’ve learned how to do this right.
Will let you know in about a week, when we build the latest prototypes and measure them up.
This short tweet came in over the weekend. Joe Cipriano, one of the foremost and well known announcers in US has been beta-testing the MixerFace prototype on location. We are delighted to hear that he is loving his MixerFace!
MixerFace is getting what will hopefully be the last update of the main Analog PCB. In total, MixerFace contains 5 PCBs. Each one has parts on top and bottom. Each one has four layers of copper traces. The PCBs are setup in an intricate arrangement, which allows us to pack a lot of functionality into the smallest possible amount of space.
All remaining analog PCBs (3 in total) have been approved. The only exception is the main Analog PCB. It houses the A/D converters, 48V phantom power circuit, our innovative monitor mixer, headphone amp and some other circuit blocks. It’s the most complex of the four. The latest revision is designed to overcome a slight bit of noise in the left channel that comes through from the digital circuitry. The analog amplifiers are so sensitive (much more so than in our MicPort Pro) and the space is so tight (this is a very small, portable product), that we have to be very careful with PCB layout to make sure that all signals are well-shielded from one another and no interference is heard.
The next revision number is 10.5. Yes, it’s been a long series of tweaks, with every version getting progressively better and better. I’m planning to deliver the files to our approvals meeting tomorrow. ‘Been working all weekend. Doing my best at isolating all the pesky signals, so that you get the best signal to noise performance in this awesome product.
