Just plug a mic into the XLR input of the cool BLUE Icicle, then plug it into your computer through its USB out -- it's all you need to record vocal tracks!

You've got a nice XLR microphone, and you've got a computer running your favorite audio software. Now you need one crystal-clear channel to get your mic into your computer. Skip the bulky multichannel preamp/interfaces and go with the simple, stylish Icicle from Blue Microphones. This compact XLR to USB preamp can accept nearly any pro microphone, with +48V phantom power for condenser mics and plenty of clean gain for dynamic mics.

Small Size, Snappy Setup

The first thing you'll notice about the Blue Icicle is its small size, light weight, and streamlined design. Although the Icicle is compact enough to fit in your hand, it contains a professional, low-noise microphone preamp and A/D converter. Setup is a snap: pl
ug your mic's XLR cable into one end of the Icicle, and connect the included 6-foot USB cable to your computer. When the USB cable is plugged in, the Icicle's logo glows a cool blue, and most computers recognize the Icicle immediately as a USB audio input.

Make Any XLR Mic a USB Mic

As you set levels and record, simply adjust the Icicle's built-in analog gain control knob to a healthy level for your sound source. The Icicle's on-board A/D converter outputs CD-quality 44.1 kHz / 16-bit digital audio via its USB output. And since it works with any XLR mic, it grows along with your mic collection. If you need only one channel of recording, and you have your own XLR mic, the Blue Icicle is a breeze to set up and use. Setup is so foolproof that the user manual read more for the ingenious Icicle is only one page long.

I’ve had this little mic interface for years... There are no bells and whistles. This isn’t going to be your all-in-one solution for recording and mixing down most music, etc. If you need to do some voiceover work for training presentations, however - it’s much nicer than having to carry around a much larger (and expensive) I/O... and while the specs are clearly lower than what you can get in something like a Scarlett or one of the Steinbergs for another $50-100 or so - a lot of what I record will never come close to requiring that level of quality (pre or post mix). I have higher quality I/O’s as well - but, different toolsets for different purposes.Throw it in your bag with an a quality condenser (or headset), and you’re good to go. Recommended. That said, I see that Shure has something out now that seems may be a worthy competitor... I’m looking forward to checking that out as well. But, this has been doing me well for the better part of a decade (or more)... that says something huge in this space, where things generally become obsolete very quickly. It just works.
