Fantastic for voice work

This device works great in leveling out our audio, and gets rid of the low level room noise. Our podcast post-processing has gone to almost zero.

Supah!

Great value for money compressor

We're using it to compress our levels for live streaming and dvd recording. The audio is clean and noise free. The compressor was easy to setup. Our pastor speaks with lots of variation. He can be quite loud and then softens towards the end. The DBX is a great compressor to moderate his volume and keep it consistent.

Great price at B&H

Still messing around with this compressor, Learning the ins and outs and what it can do. Always wanted to get a compressor limiter/gate to fool with... so when I saw the B&H advertised price,I snagged it. delivery was faster than I figured, all the way out in Las Vegas, NV Thanks B&H

Normalizes Voice Volume

By John D

I bought this compressor, at the recommendation of a friend, to level out the extreme voice volume fluctuation of my pastor. I have been extremely pleased with the result...exactly what I wanted. The pastor can now be clearly heard all throughout the chapel without me having to try and manually adjust his volume ups and downs. It takes a little time to set this up to get just the right wireless mic input into the compressor, but the result is noise free and evenly adjusted volume. On the recording, I hear no noise and the quality is excellent. I received instant comments from many worshippers on the improvement. I could not be happier!!

This compressor adds noise to my sound path. Returned it for that same reason

Does a lot for a little money

We are using this unit with two wireless lavalier mics used by trainers presenting in hotel ballrooms and consider it a bargain for how much performance improvement it has yielded. After watching a few YouTube videos I was able to configure some defaults for vocals and then fine tune using the meters and my ears. We have much better control now and fewer requests to make it louder but also not feed back while the person is standing in front of the PA while also making it not so loud while the presenter is shouting GET READY TO ROCK AND ROLLLLLL! or whatever at the beginning of the event.

Simple setup easy to use.

What would i gain by converting to dbx 266 from my current alesis 3630?

question

Can this device help me, to have the same volume always from my tv to the speakers.?
Asked by: jesus
The DBX unit is a dual channel unit generally recommended for professional music recording/production. The unit also features a Gate and Expander. Most features not required for your application. The Rolls SL33B is a popular product for your application, and can be connected between TV and receiver, or TV and powered speakers. https://bhpho.to/2qGDGNG

question

would an audio gate alone control help in a 4mic clip on mic situation that is very interactive?
Asked by: richard
First of all the gate function is designed to keep the signal muted until a level you choose to open the channel. This would not help the clip at all. If, on the other hand if you were to use the compressor side of the dbx you may be able to adjust the input and output to eliminate the clipping altogether. I would suggest adjusting the output of each channel so each channel will not exceed the headroom on the mixer, then send the combined signal into the dbx and use the compressor to clamp down on the signal a bit. There is training available for this. I am using my 266xs to make a talk show with four funny ladies, who laugh a lot and loudly fit into the available headroom while recording for broadcast. without the compressor the laughing just clips so badly the recordings are not able to be used.

question

Does this supply phantom power?
Asked by: Moses
I doubt that it supplies phantom power as it appears to be intended only for line level circuits, not mics. the selection choice is between pro (+4) and consumer (-10) levels for the rear panel XLRs

question

Does this just help in recordings, or is there a clear difference in live speaking as well?
Asked by: Jeff S.
I use it for recording only, but I believe it would work as well for live speaking as well. The adjusted sound would just go directly to speakers instead of the recorder.
