Focusrite OctoPre MkII Dynamic

Affordably Adds Eight Preamps... and Eight Compressors!

This is cool. Focusrite's Octopre MkII Dynamic does more than take advantage of your interface's lonely, unused ADAT input for a beefed-up channel count. It actually features eight "single-dial" Focusrite compressors, aimed to give you much of the character of the renowned Focusrite Red 3 (without the hefty price tag). So, let's go over it again. The Octopre MkII Dynamic sports eight award-winning preamps from Focusrite that you can pipe into your existing audio interface via ADAT. That means you can get ready to track an entire band at once. And while you track, rather than use all of your computer's bandwidth calling up a CPU-hungry compression plug-in, you can score just the right amount of compression, right from the get go. What else do you need to know about the Focusrite Octopre MkII Dynamic?

Well, you'll definitely want to know that these microphone inputs have a lot of gain. And the preamps are also optimized to handle super-extreme sound sources without clipping, so you'll have no problems tracking acoustic drums. As for the built-in compression — it sports a classic soft-knee design that "does the job," without squashing your sound. Rather, these compressors caress it. There's also Focusrite's unique "More" switch that doubles the ratio to get more of that effect-like compression, when you want it.

What about the I/O? All of it's on the rear panel, with eight mic/line inputs all in a row. The first two channels even feature DIs, so you can plug your guitar or bass straight in and start recording your ideas. And while the Focusrite Octopre MkII Dynamic makes for a great analog-to-digital solution when you connect it to the ADAT input of your trusty audio interface, this feature-packed 1U box can also handle digital-to-analog needs as well. Thanks to the ADAT inputs and eight TRS line outputs, you can monitor any digital ADAT feed. Handy. And of course, when you talk about digital gear, the issue of "clocking" is going to come into play. Rest assured that the Octopre MkII Dynamic features a stable internal clock with rock-solid JetPLL jitter-elimination technology, so your gear sounds as clean and clear as possible.

All in all, if you're wanting to expand the I/O capabilities of your recording rig and you have an audio interface you already know and love... well, the Focusrite Octopre MkII is a steal at this low price. Just connect it up to the ADAT input of your interface, park eight mics on the band you're wanting record, and you're good to go. And the built-in compression? It's there to sweeten your sound — and it certainly sweetens this Focusrite Octopre MkII deal.

Great for the price

I'm fairly new to recording, I already had the Saffire Pro 40 and I decided I want to expand on that. I was very curious about the OctoPre Dynamic because I liked the sound of my Pro 40 so I assumed it would sound as good if not better. Now, to me, the built in compressor is amazing for just about any kind of setup. Whether you want it subtle or in your face, it has a very nice sound to it. I would recommend this to any other beginners out there, it's a great preamp and very easy to use.

Great for Drums

I have used this for drums & guitars. clear preamps with plenty of gain. The dynamics can take a little bit to dial in but can help shape the sound going in extremely well. extremely easy to pair with interface via ADAT

Excellant, very professional product!

As a musician, writer, producer, Pro tools 11 user, I am always searching for products to enhance and make my workflow easier. Having the Focusrite 18i20 already, I needed something to expand my inputs, to allow a total of 18 well balanced noiseless controllable inputs. The Octopre Mk2 did the job wonderfully! The eight on panel individual compressors were a must to me for recording vocals. I can instantly administer compression to a vocalist that is overpowering the other vocals with effortless ease. Combined with the eight rotary input levels and individual led input meters, recording becomes less stressful. The 18i20 and the Octopre work seamlessly together. Focusrite's software, as well as Pro tools recognized all hardware instantly with nothing additional required on my part. In conclusion, I feel that the Focusrite products will enhance your DAW experience for a price point at less than half of comparable units with no lack in quality whatsoever. You can't go wrong!

Great Addition to My Studio

I have a Liquid Saffire56 and have been wanting to add 8 more ins... this is the way to go! It must be the built in compression, but this sounds BETTER than the 56?!! If you want to add 8 more in your studio then you better get this!! When I first bought this I thought I had messed up, I hooked it up and it would not sync. Called my sales engineer Derek Senestraro and before I hung up the phone I had a new one on the way! The new one arrived and... same problem. Come to find out , the problem was a bad optical cable, which Sweetwater replaced for free! I know this is a review of the OctoPreMkII, but I just cannot say enough about the customer service at Sweetwater! 5 Stars all around!

Focusrite OctoPre Mk II Dynamic- Just what the Doctor Ordered!

As a Physician/Drummer/Recordist whannabe, I was looking for extra mike inputs that sounded great, were easy to use, and compatible with the rest of my Logic Setup. I learned about Focusrite years ago when I got a TwinTrack Pro to go with my Roland 2480 rig for Vocal recordings (anyone old enough to remember the 2480?). When I got the computer-based setup, I got the Focusrite Liquid Sapphire 56 as the interface with the TwinTrack connected via SPIF. This worked and sounded great, but I soon got tired of plugging and unplugging mikes to record 8 channels of drums and the rest of the band in a very cramped control room space. Working with Brandon at Sweetwater (bless him for his patience), it seemed that the OctoPre was the easiest, most cost effective option for getting 8 more inputs for the drums,and plenty of inputs for the rest of the band. The best thing was that you don't need to be an engineer to hook it up, the manual was VERY easy to understand, and I knew I could count on Sweetwater support if I had problems. The sound is everything that I expected, I have tremendous Flexibility for the various recording situations I encounter, and best of all, my fat little fingers are no longer fumbling around in the back of my rack!
