THE O.P.R U871:1 Clone REVISION II
Introducing our very own, made in Australia 1:1 replica of the original U87
The accuracy of our O.P.R U87 was only made possible by exactingly following the original schematic, PCB Layouts as well as building the very sensitive high impedance components point to point on acrylic for superior electrical insulation and long-term stability. But most importantly producing our very own hand made K87\67 Capsule, which we precision machine and hand tune to original U87 parameters in house right here at the O.P.R lab in Melbourne Australia.
THE CAPSULE
100% True to the original, our K67 capsule replicates the finest example of a K67 capsule I'd came across in my research and years of servicing Neumann microphones. The K67 utilizes a dual back-plate design with precision machined holes, a center-terminated, gold coated, 6-micron German Mylar diaphragm, which is meticulously tuned and pre-aged for long life and superior sonics. All this culminates into “that” sound that you know and love.
from kick drums and bass guitar to delicate acoustic instruments, massive wall of sound electric guitars as well its ability to place a vocal front and centre of any mix. The sound heard on thousands of amazing recordings the world over.
When it comes to microphones the most important part is the transducer, be it the ribbon in a ribbon microphone or a capsule in a condenser microphone, as this is the first contact point between the outside world and the electrical domain, this is where the nuance and emotion of a performance is captured.

THE CIRCUIT
The U87i Circuit uses our own unique selection cream of the crop components that ensure signal path purity as well as replicate the sonics of the original. The O.P.R U87 1:1 clone like the original uses a single Fet amplifier driving our O.P.R U87 output transformer resulting in a rich, thick, low distortion sound with an amazing transient detail great for Vocals,bass,guitars acoustic and electric as well as brass instruments making it a true studio workhorse.
