Even some of my utilities are from Creative. The abbreviation Sound Blaster is usually at it, it is part of the brand name. Creative manufactures it all possible, here there is a small headphone amplifier, short KHV. The KHV is very small and convenient. He is the size of a matchbox. The clip holding him by the collar. Weight, practically zero. He has two TRS outputs, and a few simple controllers. Intercom connection there's also. It is designed for fun use. Music he makes, of course, but because I want to personally recourse to an audiophile product. This is certainly not his world. The USB input is the variant "micro". That's the usual pack cable versions as adjusted during tableting. Nevertheless, watch out: the small socket must be able to tolerate a little train, otherwise the cable fall out during operation. The technology is based on so-called. Low-voltage converter, ie the 5V from the USB port to be converted again to win a clean voltage as possible. Very pretentious claims the advertising: playable to 600Ohm, while the hardness is more likely in the low voltage area. All these significations are standard, and say little. Sockets, controllers, switches, etc. that are boundary conditions, where the Little KHV has to prove himself. These are vulnerabilities that can cause operational failures. Pay on purchase of irregularities. A particularly high-quality device like the iPhone does not need to actually KHV. The supplementary function refers to tablet and PC.
