Firstly, not the most practical design. It looks fine, but the knobs on top are not the most convenient solution, on the front panel they would be more reasonable, and a slightly older model has such a solution. From there, there is also a minus that nothing can be put on the upper part, which can make it difficult to link with other equipment, although in my case it is convenient to hold the adapter to the jacks in the recess on top, because. it is often needed.
Secondly, there is no power supply to the 6.3 jack inputs, so it WILL NOT BE POSSIBLE to write REGULAR JACK MICROPHONES through this card without its own preamplification, here you either need a microphone with its own separate power supply, or a separate preamplifier with the same function, then you can record this through the line input .
Further, rather unreasonable nit-picking, here the DAC and ADC are only 16 bits (although what else to expect for such money), which is generally enough for a simple recording followed by simple processing, but if you want to further engage in sound recording in more depth, then I strongly recommend buying it right away a 24+ bit map, so that later you have room to maneuver in processing. This will be the case when I bought once and for a long time.
Of the dubious elements, I’ll also note here the usb 1.1 connection, of course it works fine, and in the cross section it should pass a 16-bit signal at 41 kilohertz, but at 48, as stated in the characteristics, judging by the port bandwidth, it’s not a fact, but this is probably my mistake , most likely everything is working fine, it's just that my calculations are not correct, but still usb 2.0 would look more confident here, and preferably not in the form of the ancient type b, but at least micro, not to mention type c.
On the issue of connectors, I’ll also note that the output to the speakers here is implemented through tulips, so you will need to get an adapter if you don’t want to constantly stick them into the headphone jack. In addition, I would like to see a separate volume setting, or at least a mute for headphones and speakers, but if it is possible to adjust the volume on the speakers themselves, then you can live.
