Inside the LA610 & 6176 Channel Strips

Me being a curious dude, I decided to pop these bad boys open and check out what's inside. The differences ended up being more shocking than I had expected! Enjoy!

I would guess that the components inside the black box of the LA610 are the optical elements of the LA2A-style compressor.

I have a 6176, I wonder how it compares to a 610 plus an 1176 in terms of sound quality or any downsides to having them combined. Would you happen to know? Thanks

Inside the black box is the T4 opto element. It says Ta UA right on it.

Good eye! I should've thought of that

Hey man ! Great video thanks. What are your thoughts on this ones after a while. Have you stick to one or other? or what's best of each? Be well Man

I sold the 610 and went with the 6176. The 610 was a fantastic unit with an awesome sounding color to it! The 6176 had that same color but was a little thinner and I enjoyed having extra control over the compressor section. I now have a neve 1073spx that I am keeping forever. The UA's are amazing little units and I kinda miss them!

Does the light panel in the T4 have a part number?

[@kylew706]

The silver can is the input transformer in the 610. Also, those are the light dependent resistors on the T4 circuit not caps

Hello, I came to your page looking for answers about my 6176. It is only 2-3 years old, so I do not believe it is one of the tubes (preamp side tube), but I can be wrong. I only use it for vocals, and I never used the compressor side, so compressor is not hooked up. I am unsure if it is working or if I have it connected properly. My chain is tlm 102, 6176, apollo twin mkii quad, MacBook pro. About 2 mths ago I decided to shut my studio down, and that time everything was working great, no problems with anything, but now that I decided to start recording again my mic is not working when hooked to the 6176, so I have to bypass it in the chain to record. When I flip switch from split to join and turn knob to compressor side, and it is still not plugged in, the meter moves when speaking into the mic, but I still have no sound 😠🤯. My question to you or someone who can help is how can I find out if something is wrong, could it be something in the chain (apollo twin I attempted a factory reset), or run some type of a test. That piece of hardware outboard gear was 3k. Thanks in advance.

You plug the mic into the mic line an on the compressor side you come out into your interface set your attack an release time attack maybe at 3 fast release set the input too 5 output 3 if too much compression just dial back set your impedance make sure you got it on GR the comp so the meter will work it’s a button on the back push it in are leave it out it should be one an one on the back one in mic an output of the comp to your balance line in

looks like pc mounted potentiometers in the 610 and hard wired in the 76.
