AUDIOTRAK PRODIGY CUBE BLACK EDITION external sound card review

AUDIOTRAK PRODIGY CUBE BLACK EDITION sound card

In this article we will describe external professional sound card AUDIOTRAK PRODIGY CUBE BLACK EDITION. It has high quality digital to analogue converter Wolfson, which works on 94 kHz frequency with 24 bits precision, and National Semiconductor LME49860 operational amplifiers ( OpAmps ), which provide high quality sound without addition of noticeable amount of noise. There is ability to replace them on OpAmps of even higher quality, because they are mounted via special socket. Card has built-in electrolytic capacitors Sam Young AHS Series in digital and in most of analogue parts of it; from one side : they have good enough quality, but from the other side : it is better to place into analogue tract ( and into digital also ) high quality ceramic or film capacitors, because they have much better quality and characteristics, than electrolytic capacitors, for audio tract. And only in Low-Pass filters after OpAmps it has film capacitors WIMA Film Capacitor.

Mono-bicycle ride into Chelyabinsk prairie

Yesterday I rode into little bicycle trip into Chelyabinsk prairie. I headed to Upper Ufaley through Poldnevaya and Cheremshanka villages. It was +8 degrees on Celsius at the morning, Sun was shining and there were no wind, so it was nice to ride without overheating. On the road to Poldnevaya village foresters burned trees branches and there was pleasant smell of wooden fireplace above the road. At the beginning of day it became warmer and ride felt almost like at Summer. Trip from Poldnevaya village to border of Sverdlovsk and Chelyabinsk regions is very pleasant, because of highway with very good asphalt coverage. But later and to the Cheremshanka village : hard ride goes on, because there are long slopes to Itkul lake and lots of bumps in the road with the ability to ride into them on high speed, which lead to the flying above bicycle handlebar. On the road I met 2 bicycle riders and after 10 km another one, I greet them and they answered to me the same.

Most of the road to Cheremshanka village I rode without problems, but closer to it on one of the slopes I punched through my tire camera on one of the stones. I stopped and replaced camera ( there is need to note, that one car stopped and offered to me help, I gave my thank to driver, but refused his offer, because I already handled situation by myself ). To not to play with the fate without replacement camera and to not go back on my feet to my home 100 km, if camera will be punched again, I rode slightly ahead, climbed hill near Cheremshanka, ate my lunch and moved back to home. I rode back not so fast to keep my tires safe, and road to Polevskoy was without problems. On the way back I met the same two riders : it is pleasant to met them again, we greet each other and continued our ways to our homes. Next : calming ride after sunset on the highway, that is lit by street lights, was went on. At home I ate my dinner, made slight repairs and adjustments to bike and went to sleep. I rode 130 km and made following conclusions for my next rides : there is need to take with me 2 replacement cameras and cameras repair kit, so that there will be no need to turn back on the 2 / 3 of a way. Now : see you on the next bicycle event, I’ll prepare to it much better, so that there will be no need to turn back on the most interesting part of a story.

Review of external semi-professional sound card ESI UGM96

In this article we will review semi-professional external sound card ESI UGM96. It was released in 2008 year, but in this electronics segment devices become obsolete not so fast, as in other areas. It has 2 unbalanced stereo outputs and 2 unbalanced mono Hi-Z inputs. There is ability to switch one input into microphone input with preamp mode; and there is ability to switch one output into linear mode, so that signal is not processed by sound card’s amplifier. It supports playback modes up to 96 kHz and 24 bits and the same recording modes. There are drivers released for sound card for Windows 10/8.1/8/7/Vista/XP ( with ASIO support ) and Mac OS X 10.4 and newer ( with Core Audio support ) operating systems; support of these professional audio playback and recording interfaces allows to do this with very low latency, which is extremely important in professional work with audio. Sound card is fully powered by one USB port. Card has 2 stereo outputs, but does not work in 4 channel mode : both outputs transmit the same signal; it does not support hardware acceleration of 3D sound in games and virtual reality applications ( but software implementation of these functions works without problems with this sound card in all applications ). Sound card sizes are 7 x 8 cm. Based on my experience of work with ESI UGM96, I can say, that this is great sound card : quality of music and sounds in films and games is great; quality of audio recordings with good microphone is also great, and card is supported by all moderns DAWs : FL Studio, REAPER and other. Package contains : ESI UGM96 sound card itself, USB cable, CD-ROM disks with drivers and additional software and user’s guide. There is need to note, that this sound card has one of the lowest prices among external semi-professional sound cards.
