I'm getting a second UA LA-2A for choirs and harmonies and was wondering if someone has linked them "in order to achieve the same amount of gain reduction from each of the two units to maintain stereo imaging". When would this be so important?
I'm a bit worried about messing with things (R3 pot) because, well I've never done it before, and I won't be using them like this all the time. Maybe I shouldn't even link them because I don't necessarily need the perfect link? I've read many times linking is less desirable to ME than a plus.
It sounds like all I need is simple guitar cable that I keep within 2 feet and tie them to both 6 and 7 terminals yes?
Asking ahead for any advice.
Opinions on linking and the LA-2A please share?
Here is the manual but below is what it says: Great Eyeballs - Purchase - YouTube
Stereo Balance Adjust (R3)
For stereo operation, two LA-2A units are interconnected in order to achieve the same amount of gain reduction from each of the two units to maintain stereo imaging. In order to accomplish this, terminals 6 from each unit should be connected together. Additionally, their grounds (terminal 7) should be connected together. The interconnecting wire should be less than 2 feet in length and should be shielded. The shield should be used to connect terminals 7 from each of the units together.
To calibrate the units for stereo operation:
- Connect the units together as described previously.
- Turn the Peak Reduction knob counterclockwise (no compression).
- Set R3 on each unit to a clockwise position.
- Set each meter to read Gain Reduction.
- Adjust the Peak Reduction control on the left channel until approximately 5dB of gain reduction is achieved.
- Adjust R3 on the unit that shows the greatest amount of gain reduction until the gain reduction indications are equal.
- When operating, set the Peak Reduction controls to the same setting on both channels.

Remy, Once I strap them together, but on occasion go mono, do
Remy,
Once I strap them together, but on occasion go mono, do I have to reset the R3 pot on the back and all the fuss or what?
Can you please explain more on how to do a multiband process with two LA-2A's? You've got me excited over this!
Here's an old post regarding phase issues:

You could create the multiband compression with a 3 band active speaker crossover. It would require 3 separate real time passes. You would record each output from the crossover to separate pairs of tracks and post LA-2's back into your Lavery to be printed to a nether pair of tracks. Lather rinse and repeat with mid & high frequency outputs from the crossover with the LA-2 post-crossover. Then you'll be able to combine them all to bounce the 3 pairs to a finished stereo track. At which point you could then add additional Mastering trickery. Of course you don't have to use an active speaker crossover network, if you have proper equalizers, you can create your own spectral overlapping regions. And depending upon the equalization you utilize, your crossover could be FIR or IIR. And you would also have the ability to select 6/12/24 DB per octave filtering. It would be awesome to screw around with that. Can't wait to hear what you come up with?
Surely someone must have done this in times gone by?

Yeah this is no big thing. Remember these are also utilized in f
Yeah this is no big thing. Remember these are also utilized in front of the FM exciter/transmitter where they wanted left and right channels to track. An additional pair may have also been utilized independently compressing Mono from Difference. And then everybody got multiband Duoghrough Processors, Orban 8300, CRL and all the rest. And even on those, you can elect to strap the spectrally separated bands and in every combination. So sometimes, if you are processing matrix Mono/difference channels, you won't necessarily want that stereo strapping and if you want to go for a wider ambient feel and perspective. But if you are processing left right as left right you will want that stereo strap to keep your center image from shifting left to right.
One of the cool aspects you may have going here Chris is that since you are utilizing this in a postproduction aspect as well as during tracking, you can create your own multiband compressors with just a couple of passes through your 2 LA-2's. I think that would be awesomely awesome! And with your quality converters back and forth should make it sound even more bad ass.
Oh wow!
