Although the potion uses a FET (Field Effect Transistor) as the gain reduction element (like a well known classic limiter), the control circuitry (or side chain) is a completely new Buzz Audio design with some real innovative techniques to achieve an original compression characteristic. Included in this new circuit is an element we have nick named "Ready To Rock" (RTR). This circuit automatically alters the Release time setting of the compressor depending on the attack depth and prevents the compressor from over shooting and undesirable "pumping" when using faster Attack settings. A front panel LED indicates when this is function is active. (Actually, RTR stands for Release Time Reduction, but call it what you will!). As you can see from the specifications, the FET itself produces a relatively large amount of harmonic distortion compared to Optical and VCA compressors, but this distortion is the sound that will add energy and richness to your tracks. The potion is capable of of very fast attack (less than 50uS at F attack setting) and when set to 20:1 Ratio, we believe it approaches the performance of "look ahead" digital limiters within the constraints of the analogue domain. The audio section of the potion consists of our unique True Class A BE40 and BE50 amplifiers coupled with Lundahl input and output transformers for a fast yet full sonic signature. The input signal is passively coupled directly to the FET element via the input transformer, amplified and balanced via the ouput transformer - a simple signal chain. In addition to the Gain, Drive, Attack and Release controls, we have included a % Mix control which allows the user to mix the uncompressed (input) signal with the compressed (output) signal providing yet another means of obtaining an original sound on your tracks. The potion consumes 2 slots within the 500 Series frame. The audio in/out connectors of the first slot carry the main signal path whilst the in/out connectors of the second slot are utilized as a side chain insert point where external equalization can be applied to alter the compressor sensitivity at different frequencies. This insert can also be used for compressor "keying". A switch on the front panel allows the user to monitor the side chain insert and switch it in and out of circuit. Two potions' can be linked for stereo (mix bus) operation.

OK... Sorry... I'm answering to my own question... Potion is more aggressive Essence smoother and more transparent Did I get it right? heh

Buzz Audio SOC-M

...mix a whole album with just those two. Hey Tim Farrant , have you ever thought about bringing the Potion back in a mastering version in a one or two space rack? That'd be killer. Is a mastering FET even a thing? :lol:
