USB Dual Pre Two Channel Preamplifier/Computer Interface (USBDUALPREPS),Black

I'll get to the point, this device is reasonably priced even at its highest street price. I paid $69.00 and it's worth every cent. I am a recording engineer and musician.Rugged constructionVery low noise floorPlenty of gain in mic preVersatile power supply accepting 7.5 ~ 12.0 volts AC or DCPhantom powerWorks with my iPad V1 and makes a fantastic input to Ampkit+, GarageBand, Sonoma 4Track and other audio apps with no noticible latency. This device is a great addition to those using the iPad for recording purposes.NI's Guitar Rig for iOS DOES NOT recognize this unit. Bad move on Guitar Rig's part but then their amp models are inferior to the Agile AmpKit models anyway. It is unfortunate though as Guitar Rig has a nice multitrack recording option.WARNINGS: On a PC the latency is unacceptable even with ASIO4All. Also, you must have the camera connection kit to interface this unit with the iPad. Unfortunately, along with the severely degraded battery time with latest iOS 5 "upgrade" the iPod will still not work with this unit and the camera connection kit.

The media could not be loaded. The video is simply this...an Audio Technica AT897, going into the Art Dual Pre, then straight into my Canon t3i (600D). I am very happy with the result as you can hear clearly how important a pre amp is when recording with (anything) but especially a DSLR. this is a good lesson for us in understanding how important a decent pre amp is in the signal chain.So...you are buying this product because of it's practical usage and variety of features. It is small, sounds great, has low noise, and get's the job done in a pinch, with many options for powering the unit, phantom power, headphone jack, portability, etc etc. It works. It is the cheapest and therefore best solution for DSLR video people like myself, who have no money.2 things I REALLY wish: 1) some sort of mounting option, weather it be mic stand mount or camera stand mount...there videos online about how to drill holes and add your own mounting system, but bleh. Such a missed opportunity!and 2) the battery compartment. were they joking? if you can manage to figure out how to get the wires out of the way and cram the battery into the little cardboard battery compartment, then you realize it's impossible to get the thing out...I got mine out by pinching the leathery + - connectors and ripping the battery out. luckily nothing was damaged. Now, I know that I cannot push the battery in all the way. This is inconvenient and makes the unit look ugly, since the battery is always sticking out...because if I push it in, well, that's just not an option. Oh well!all in all, the juiced riggy assist is amazing and perfectly designed for DSLR people, but it's really expensive. THIS, is cheap, and I would say, in spite of the flaws and poor design, it is WORTH it for those who are on a tight budget. it's worth it because the features that matter work well and sound good. it's just that darn battery compartment.

I finally got a chance to use this little beauty for two recent live recording sessions, and I am extremely satisfied with it.I recorded two live vocalists using Shure SM-58 microphones. The only musical accompaniment was a "harmonium", an Indian classical instrument that's like a keyboard driven by a hand-operated bellows like an accordion.Both the sessions were unplanned and spontaneous, recorded in a normal living room, and that's exactly the kind of situation I had in mind when I bought this unit. Earlier, I would miss out on recording such sessions because of the hassle and time required for setting up my Peavey PV-10-USB mixer, which is not exactly portable nor light-weight. OK, I do miss out on having a couple of extra mics for a background singer and the harmonium, but the compromise is well worth it in terms of sheer ease of setup, and most important, WITHOUT any compromise in sound quality.The setup with this unit is extremely simple. here are the steps I followed:1. Plug the mics into the XLR input jacks on the front2. Conenct the unit to your PC with the USB cable - if you have Windows Vista or Windows 7 it is recognized immediately as a USB device3. Select "USB audio codec" as your default recording device in Windows by right-clicking on the speakers icon in the taskbar4. Choose he recording properties that you want (I picked stereo / 16-bit / 48 kHz) and save this selection by clicking OK5. Fire up your recording software ( I use Sony Sound Forge)6. Set the levels of each channel using the hardware gain control knobs on the device7. You are ready to recordAll the above steps took me less than 5 minutes. My PC runs Windows 7 and it worked without a hitch (Windows 7 rocks, by the way!)Note that I do not monitor the recorded sound from my laptop while recording - I simply use headphones plugged into the socket at the back of this unit for real-time monitoring.Sound quality:I essentially purchased this unit to get around the limitations of my PC sound card - I wanted the A-D conversion taking place outside the PC, and that's exactly what this device does very well. It is capable of 16-bit digitization at a maximum sampling rate of 48 kHz, i.e., better than audio CD quality.Each channel's sound was crystal clear, capturing the highs and lows with zero audible distortion. I had set the gain control knobs about halfway (between 8 and 14 db on the dial) such that the levels on my recording software did not exceed -4 db on average and -1 db at peak. I could NOT tell the difference between the sound quality recorded with this device and the sound I recorded with my Peavey mixer (using the same microphones and the same singers). I don't believe that the unit itself adds any significant distortion to the sound, and you will essentially be limited only by the quality of your microphones.Caveats:1. Vocals obviously have a limited frequency range, so I cannot say what the sound quality will be for extreme highs and lows. But in the range I recorded (approx 800 Hz to 3 kHz), it was flawless.2. All my recording is in casual settings, i.e., NOT in a studio. There is a fair bit of background noise, so again, maybe there are subtle differences which may become noticeable in a studio environment using professional condenser mics.Dislikes: Just two minor cribs:(1) The choice of colours for letters/numbers makes them slightly hard to read - I need to squint hard to read them.(2) USB cable not included.Neither of these problems are significant enough to dock a star, though.Likes:1. Very compact and yet very solid build quality2. Needs no external power - draws USB power from the PC3. Extremely simple and flawless setup - I didn't even need to read the instructions4. Can handle condenser mics as it has a 48V phantom power supply5. Universal mic input jacks - XLR and 1/4"6. Headphone monitoring with its own level control - very helpfulOverall:A strong "buy" recommendation, if you want to make quick and easy CD-quality live recordings with extreme portability. Absolutely amazing value for money - there is nothing in the market at this quality and price point that I am aware of.

I bought this to amplify my ntg 2 shotgun for video. It didn't work, wouldn't put out enough signal at all. It was a kluge, anyway, and I ended up getting a tascam dr80, which worked great-- Very clean, excellent adapter, allows monitoring. I'll probably throw this away.

wir benutzen den Verstärker mit einem Rode NTG2. Das Ding funktioniert tadellos! Durch die Multi-PlugIns an der Vorderseite, lassen sich zudem noch viele weitere Eingabegeräteohne Adapter anschliessen.

This was bought primarily to record onto my iPad with GarageBand and Auria. I have an iPad 4 on iOS 7. I was unsure of which audio interface to buy as there has been much decrying of iOS 7 in the recording community, with many people not updating until they know their devices will work.I thought I'd take the plunge and as this is a relatively cheap device I thought I couldn't go wrong really. Well I have to say this little device blows me away. It is so small and light and is able to be powered directly from the iPad, not requiring a power source or battery, although they can both be used if desired. It is able to take both line inputs such as guitars or keyboards, or XLR for microphones. It also has a 48V phantom power circuit for condenser style mics that require it. Guitars sound sweet through this on GarageBand and Auria, although I am using the Ampkit app to get great sounds for recording. It will allow the recording of 2 tracks at the same time from different sources.The rotary knob on the rear allows you to mix between the dry sound going into the device and the wet, effected or recorded sound coming out of your software; a nice touch.If recording to an iPad you will need a camera connection kit/USB to lightning converter. A normal USB lead is supplied with this device.A fantastic piece of kit for the money.

good stereo pre amp

Using this to record my classical guitar into my pc. Using 2 inputs to the interface. The first is a piezo electric pickup under the bridge with its own pre-amp and the second is a condensor mic both are XLR. From there i'm using the usb straight in. Works perfectly with no buzz, i'm using windows 7 so there were additional steps to make but they were explained and not anything major.Naturally it does change the tone which isn't ideal for classical guitar but my mic and piezo aren't highest quality anyhow and they have a larger affect, I'm doing sound editing anyhow so i can work with it. Overall it's precisely what I expected and what I paid for. Nice!

Driver issues. Cheap usb to xlr converter worked plug and play. This unit was a pain to get working across multiple laptops.
