Overview

Sora is a versatile push-pull tube saturation and distortion device intended for audio mastering and mixing applications.

Due to the wide range of precision controls it excels in mastering and master bus use, and the use range covers many other grounds as well.

Sora is equipped with MS encoding and decoding, two sets of different interstage transformers, and a wide variety of precision adjustments for ultimate versatility. The character of the unit is solely created by the SQ Phillips NOS pentode tubes and the Lundahl interstage transformers. There are two C-core transformers available, a silicone iron core and a nanocrystalline, and the Sora design allows the user to toggle between the two transformers during operation. While the silicon iron represents a “normal” transformer with some character, the nanocrystalline has virtually no hysteresis, thus adding no coloration throughout the audio range.

The rest of the circuit utilizes the best available JFET input IC operational amplifiers (OPA828) for absolute transparency. One of the key features of Sora is the opportunity to select the frequency range to be processed using the X-Over filters while retaining a flat frequency response. Sora also features a parallel processing capability and an unprecedented ability to tailor the distortion spectrum.

All rotary controls, except X-Fade, utilize Elma rotary switches for ultimate precision and longevity. X-Fade is an Alps Blue potentiometer which is known for excellent channel balance.

There are three regulated low voltage supplies and no less than six regulated high voltage supplies. The voltage supplies consist of a separate anode HV supply for each channel and an adjustable HV supply for each tube’s screen grid, allowing for individual bias current settings without compromises in dynamic response.
