Should have had this a long time ago...

I haven't had this unit long, but it has done all I ask of it. Protects my gear and I have noticed a much quieter signal from everything. I use some old Fender and Vox amps and some newer plus all my pedals etc. and it has performed perfectly and everything is not only quiet but safe. Thanks to my sales engineer (Greg Baum) for recommending this unit. So far, so good.

I Love It!!!!!!!!!!!!

I was using my gear with no power conditioner and I heard hissing noise hums and it was just not right. Now I finally got everything hooked up and I notice an big difference. Everything sounds better.I can mix my songs the right way now. And the best thing is, I know my studio equipment is safe and protected. Shout out to my sells engineer TONY DAYTON for looking out for me on this one Thank you Tony. And thanks for the candy. But if you need clean power buy this power conditioner worth every penny.

An Insurance Policy with Rack Mount Ears

Clean, safe, reliable power. 3 stage on and off. Peace of mind. Even comes with a goose neck lamp too.

The right choice.

The right choice for anyone looking for clean power in their studio. Plenty of plugs in the back for digital, analog, and high current (amps, monitors, etc.) I use the 3500 for everything in my studio from my computer (digital) down to my analog preamps and summing amplifier (analog). I am about to get another for the studio I like them so much.

Complete Silince

The Pro 3500 is just what is says it is, "Pro." I run a very expensive and complex recording studio with a lot of outboard vintage and new gear, and require 3 of these units to accomadate all my equipment. The difference between using the Pro 3500, and not using anything except a powerstrip is night and day. It is as good as there most expensive unit, but my need were best met by the stage 3 filtering, and other particular protections.
I also have a Furman Power Conditioner that I use for my least important, and least used gear. It doesn't even come close to the Monster Pro 3500. Buy one, it will move your studio up a whole step into the big boys, as far as A/C protection, balance, filters, and surge.

Clean Power

Super clean power. Didnt realize how "noisy" my system was until I powered this unit up and heard nothing. No hiss, no hum. Just silence. Wouldnt use it for a live situation, but in studio, I wish I would have gotten one sooner. Plus, ya cant beat hitting one button then watching your hardware come to life piece by piece.

The Pro 3500 Works

The only reason for the rating is that with a higher budget a consumer can buy a more expensive one, or with a lower budget a least expensive one. I found that I can plug everything that I need to into it, and still have some amperage left over. And it works with tri-filtering mode protection with clean power stage 3 on the most important digital equipment and studio equipment with lowering the noise floor level and dirty power for everything I consider important. It does make a difference and it works for my budget.

Helps reduce noise

The cool thing about this unit is its three types of noise filter: high current (for amps, powered speakers, etc.), analog (mixers, preamps, etc.) and digital (for hardware samplers, workstations and synths).

I achieved a noticeable noise reduction on my Fender guitar amp. Also, I used to hear a loud thump every time I powered down my studio monitors and my guitar amp. These noises are now gone. Another cool thing about the 3500 is the switched power on/off mechanism helps shut down your gear in the right order and protects your gear. It's also cool that you can read the voltage fed to you outlet, even if the unit is off.

If you want to regulate the power and have constant voltage this is NOT what you're looking for. You'll need a line regulator for that. Equitech makes great balanced power products but is very pricey. Furman IT series would be another option.

I recommend you wire your studio with the star grounding method to minimize ground loop related hum. That said, Monster Power 3500 is a great option for surge protection and taming different kinds of noise in your rig.

Great for Studio Environment, Not good for Live Environment

Seems to work good for a Studio Environment, but long power up times (sometimes doesn't turn on at all), makes it unreliable for a Live Performance Environment.
