Vintage BBC Belclere ES 8325 Transformers - Also known as Audio Gold!…. as you’ll hear in the video on TheYouTube if you search for: Vintage Analog BBC Belclere ES 8325 Transformer Clipper Saturation for Mixing Mastering Music Audio
Built by Belclere (who made high end transformers for the BBC, Neve and Alice desks to name a few) these things are so transformative it’s a night and day difference between a flat mix on your computer etc - and a mix processed with the stupendously lovely analog saturation and dynamics these beautiful guys bring to the party.
They’re freaking amazing.
Even on the crappy youtube vid you can hear the stereo width, 3d space, punch, saturation and clarity they bring to the proceedings.
At low saturation settings (we use logic’s i/o utility for this) the soundstage just feels more settled, the mix elements more gelled and “placed”. The more we push into them this 3d-ness just get more enhanced - which is why a lot of high end mastering engineers have a collection of passive analog transformers just like these to take mixes to heights not accessible to digital plugins.
The clipping you get from top quality transformers like these will give you 3 to 6 db of transparent gain - with no fizziness or breakdown from any of the frequency ranges (so long as your audio / bus is at -6db or thereabouts and not some woofy mess) - as well as tempering any nastiness in the high mid to high frequency ranges.
They’re superb for sweetening and processing individual elements in the mix like vocals / bass / synths / drums - but are also Very happy enhancing complex mixes like classical or film stereofields.
A Gift to the audio mixing and mastering communities!
As per the video - you can hammer them to get some creative clipping / distortion, and as for distortion …… I added a switchable passive diode distortion circuit to enhance audio even further which turns this rack into a superb creative device as well as a mix / bus sweetener.
For mastering or mixbus duties - turn on the distortion and don’t push too hard into them … it’ll be like turning the lights on!
Run your vocals / bass / synths and drums etc hard into these babies to hear them blow up in the most satisfyingly musical way … it’s a thing of beauty!
Balanced jacks in and out.
These transformer racks of mine are the cheapest - easiest ways to get classic analog console 3d, dynamics and saturation into your mixes and masters … give your music a little kiss!
