Master Bus Transformer (MBT)
From Rupert Neve Designs:
For over six decades, audio transformers have been the bedrock of Mr. Rupert Neve’s audio circuit design philosophy – and Rupert Neve Designs’ bespoke transformers are an integral part of virtually every RND product.
Packed with these transformers, the MBT provides an incredible array of flavorful options designed to sweeten, enhance, drive, widen, and utterly transform source material, making it the ultimate tool for musical coloration.
With 3 octave ranges, gentle slopes and minimal phase shifts, the all-new 2-band Shelf EQ section was created with an emphasis on simplicity and elegance. This smooth & musical EQ is excellent at providing just the right amount of tonal enhancement – especially when it is interacting with the other sections of the MBT.
