Audiophile Analog to Digital converter, Phono preamp with DSP equalisation, USB /SPDIF/TOSLINK digital output, 44.1~192kHz sample rate, Remote controllable for pocket size all digital Phono setup, Record your vinyl at ease.

The miniDSP ADept is a compact high-resolution A/D (analog-to-digital) convertor that accepts single-ended (RCA) or balanced (on XLR) audio signals. The digital output is available on SPDIF coaxial and TOSLINK optical connectors, and can also be recorded to a computer or mobile device via the USB-C connector. Adept combines low latency, high sample rate and extremely low noise floor performance to provide optimal digitisation of your favourite analog audio content.

The miniDSP ADept is also a phono preamp (with a turntable connected to the RCA inputs) with accurate phono equalisation for moving magnet or moving coil cartridges. In addition to the standard RIAA phono equalisation curves, we've used the power of DSP to provide additional curves that will be of interest to the keen collector of older vinyl. A range of input gain, resistance and capacitance values are provided to optimise for any cartridge and can easily be saved and recalled in your favourite preset.

miniDSP once again innovates with audiophile performance in a package that doesn’t break the bank.

work well
Color: Blossom
these work really well on your screens on your phone and laptop. I keep one of them in my car for the computer screen. there are 4 of them so you can leave them in multiple places and always have one handy. the designs are fun. they clean well with a little pressure. they do not scratch the surfaces. they are nice and soft and small enough to keep in your purse or wherever.

These are handy and effective!
Color: Blossom
These work really well for cleaning phone/tablet screens, the display screen in my car, and any other screen surface. The material is soft and doesn’t scratch, doesn’t require any liquid cleaning product, and does a great job of removing smudges and dust. I like how portable they are-I can keep one in my car, one in my purse, one in my work bag, and one in my nightstand. I’ve reused them multiple times and they have stood up well to multiple uses with no apparent loss of cleaning ability.

Work great, inexpensive, but…pic just a tad different
Color: Glitter Pink/Black
These work well, were worth the price, and made good stocking stuffers. I took off 1 star, because they appeared somewhat different from the photo. The photo made the glitter ones looked like they had stars as part of the pattern (like a night sky or outer space), but it seems like that effect was added to the photo to enhance the glittery appearance. They are, in fact, very sparkly and not very celestial, so they were just a tad more ‘girly’ than I was expecting. Nothing wrong with glitter and glam—just different from what I thought I was getting. On a positive note, the glitter is sealed in and doesn’t shed, so you won’t be spreading sparkly escapees for the rest of eternity. (I guess I would give 4.5 stars if I could)

Where have these been all my life?
Color: Glitter Pink/Black, Color: Glitter Pink/Black
I don’t understand why anyone would give this set of little miracles a bad review. I have wasted way too UHC money on too many products that never get my phone completely street and smudge free, especially around the edges where the phone and the case meet. That’s the area I’ve wasted the most time trying to get clean, to no avail. I have spent way too much time wiping the edges and corners over and over, but they never are completely streak-free. I saw these and figured I’d try them; it’d not like I wouldn’t be able to return them if they ended up being a just as useless as everything else I’ve tried, and even if I did forget to send them back, I wasn’t losing a ton of money. The first thing I did when they arrived I pulled one of them out, shoved two fingers under the elastic band, a major selling point for me because it keeps it secure without feeling claustrophobic., and started swirling all around the edges of my phone. And within seconds my phone screen looked brand new. The oily grime stuck in the corners and all along the edges was gone within seconds. Without any cleaning solution too, which I love that it’s an eco-friendly solution to keeping all that grossness off of my phone and tablet screens. I was in the middle of making cupcakes and had the bright idea of smearing a bit of butter on the screen of my tablet to see what happens. The results speak for themselves. And there’s no gross oily residue left on the pad I used to clean my tablet either when I was finished. I’m sure there’s an easy way to clean them…I’ll look into that when the need arises. The only issue I have is that I can’t buy them in an extra large size for cleaning tvs. The small ones will work perfectly, but an extra large one would get rid of every streak, smudge, fingerprint and lint within a few seconds. And you get it clean without any cleaning spray. You don’t even need water. Just open it up and use. I’d buy one to keep behind every tv in my house in a large size! They are the perfect size to keep in your purse or your pocket. I bought the glittery ones; my ADHD brain is immediately drawn to anything that sparkles. And getting four for the price is beyond a great deal. I highly recommend these little wonders if you are like me and hate seeing your grandchildren’s fingerprints smeared all over your tablets screen when they hand it back to you. Or if you reach the same level of frustration I’ve reached whenever I’ve tried to get every bit of oily grossness off of my phones screen. These are going to make great white elephant and last minute Christmas gifts and stocking stuffers. They arrived a day earlier than I expected too. Get these. You won’t regret it. Until you try them and you regret that you can’t get an extra large one for your televisions too!
