Fully Assembled OLA5 Opto Compressor by DIYRE with Vintage Output & 2520 DOA
There is nothing like classic opto compressor OLA5 to get that large vintage-audio sound on your drums or audio program. Discrete Op-Amp and vintage iron-core transformer signal path options are included with this beautiful unit. After running some tests in the recording studio we were amazed to hear the huge 1970’s vintage-audio sound that came out of this unit. The subtle undertones and artifacts sought after via 1960’s and 1970’s break-beat records are all produced by this compressor / limiter. We set the ratio to 12:1, enabled the high-pass filter and limiting, set the threshold, set the mix to “wet” and started to drive the limiting circuit. OMG; the depth of the bass tones, the heaviness of the drums and the beautiful background reverb all stood out in a way I’ve not hear other gear achieve. Huge sound on the drums! Use these on individual channels or the stereo mix. You would need to spend well over $1,000 to purchase a unit that would sound even close to this one.
Classic Opto Leveling, Upgraded Signal Path: The Urei LA-4 leveling amplifier has always lived in the shadows of it’s older siblings, the LA-2A and LA-3A. Despite possessing the distinctive, musical compression character its family is known for, the LA-4 was compromised by the muddy sound of early chip technology. These units set the gold standard in the 1960’s and 1970’s regarding compressor / limiter quality and tone, 1000’s of recordings have been released using these classic units.
With the OLA5, DIYRE painstakingly recreated the LA-4’s leveling behavior—including cloning the original opto cell after finding that no modern substitute would do—but that’s where the resemblance to the LA-4 ends. The OLA5’s signal path is completely overhauled and upgraded. And the workflow hews closer to the LA-2A and LA-3A, while adding new features like a side-chain high-pass filter and parallel MIX control. No doubt, this is one of the best “bang-for-the-buck” Compressor / Limiters on the market!
Modern Clarity or Vintage Tone: As with the EQP5 Equalizer by DIYRE, you can choose between the Modern Output stage for more transparency or the Vintage Output for a thicker, more colored sound. The vintage output is upgraded with an iron core transformer and 2520 Discrete Op-Amp. Select vintage or modern output modes without any soldering. There are 2 jumpers on the board that allows you to change options. In theory you can add a panel switch to these jumpers and the Ratio jumper if you’re so inclined.
