Smooth N Sweet

I got this to help Vocals and Guitars Woodwinds when i track and record. This is wonderful and adds a NEW color to my arsenal. Side Chan and Analog or digital. I keep mine in Analog mode. It takes some tweaking and all of a sudden you have all this width and smooth lushy sound!. I keep the EQ section neutral most of the time then when i need to pull more highs or repair a mix missing lows or vibrance i tweak to worlds of delight. The compressor is so cool. Quick but no compromise in transients. Two chan in..two channels out. Just the way I like it!. Mix this into a Rupert Neve Portico II MBP and you will be unstoppable! I mean talk about vintage warm and fat! This unit alone will get you surrounded in down comforters, adding Rupert Neve to its output is like taking an olympic gold medalist and giving him everlasting youth. This is a professional studio snd. WARNING DO NOT OVERDUE it with this unit. It is easy to crank it all up, turn knobs. But you can do allot of damage if you don't understand what each knob does. You may think your mix is great only to find out something is not there or like super saturated. For those who know no worries. For those who don't just read the manual and add small amounts until you understand what it does. Having all the cool red lights on does not mean your doing an awesome job! You can take old washed out mixes and repair them. You can add so much warmth to a Vocal that you will be in heaven. You can run your mic'd guitar or woodwinds through this and BAM!! you will sit back and smile. I wish some nerd at Sweetwater would come up with colored back lights for the VU meter!. Dieing to have Blue or Green or Purple Meter. That way I can enjoy my custom unit and show it off to girls that come in my studio when i record. White gets old! Girls like Purple and Blue and Pink lights! Cheers

Essential to my workflow

This is my second 747. Why would I need two? My original one, that I've had since they started making them, needed some work done (after being on 12-16 hours a day for over a decade), and my mixes just aren't the same without it. So in order to keep my studio rolling I went ahead and bought another one. When I get the original back it will not be a 'problem' finding a job for it to do. :-) And this way I have a spare, just in case. One interesting thing about the 747 is the ability to switch between solid state and tube with a button. Though, the 'tube' sound always wins. Yes, its the 'glue' that you hear as a buzzword all the time, but its also 'lush' and 'deep'. The Program Equalizer is the function I rely on the most. That 32k shelf slider is always up, just a touch, to give my mixes this beautiful air. One other use that this compressor shines on is using it form the overhead mics on a drum kit. With a great drummer, kit and room, you could almost use just the overhead mics for the drums at mix time. It just sounds that 'complete'. If you aren't convinced yet that this is a beautiful piece, there's not much I can tell you, but if you do plug it in, you will hear what I mean. Highly recommended!

Awesome

This is basically a one stop mastering solution. With this, good A/D/A conversion, and a software brickwall limiter, your mastering needs are basically taken care of.

Simply Exquisite...

"If you are considering a 747, chances are you already know of Avalon's sterling reputation. The 747 meets those expectations head on - and delivers; offering two separate signal paths (tube or solid-state), for great sonic flexibility. Want "tube warmth" - got it. Don't need it on this project, no problem; flip a switch, you have clean Class A sound (with a TON of headroom!). I use one in my mastering chain, sending the 2-buss out of an Akai DPS24, into the Avalon 747, and finally into an Alesis Masterlink. The compression is typical Avalon; top shelf. Frequency bands on the EQ were specifically designed for mastering applications and couldn't be better picked. You can easily roll-off the power-robbing LF "mud" in a mix, add clariy in the mids, and a distinct sheen on HF's. Or not. Another great option is being able to use the 747 on keyboards and stereo guitars. While it lacks mic pre's, the unit can work wonders on a key patch, and gives a 3-dimensional feel to guitar processors, defining solos and bringing them "out" in a mix. Very pleased with my purchase - you will be too. It's helped my masters sound more professional and it will help yours as well. Take the plunge - you won't regret it!

The VT-747SP delivers in every way. The VT-747 features the same stellar sonic quality that the world has come to expect from Avalon while still delivering a look that is sure to impress and inspire.

Derek Senestraro

An ideal cure for any mix that sounds "too digital." Just add it to your mix bus and listen to the magic. Use the solid-state path for a little punch or the tube path for that extra vitality and gloss. The VT-747SP is at home in any pro or serious project studio.
