Pardon our dust as we work on this section. Hope to have it finished soon.
Most audio product documentation is organized around individual product models where each product gets its own stand-alone product manual. We make limited use of this approach.
Instead, our product documentation is organized mostly around the underlying vintage (version) of technology used in our audio preamps, i.e. V1, V2, V25 or V3 (current). Thus, if you have any of our current V3 model preamps, the greatest concentration of relevant information will be found under the V3 Attenuator/Controller section of Docs.
