Rupert Neve Designs MBT Master Buss Transformer

Transform your tone.

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.

Create Tonal Magic with the Shelf EQ

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.

Find New Dimension with Width

The Width section is designed to increase the perceived stereo spread without losing low-end focus.

While inspired by the Stereo Field Editor (SFE) “WIDTH” controls found on our award-winning Master Buss Processor, the MBT’s Width section has several key differences:

The Width control on the MBT is additive only, with a greater range for more extreme operation.
There is a variable high-pass filter (50Hz to 800Hz) to adjust the Width content, so that low frequencies remain more centered in the mix as the mids and highs are spread out to create more space.
Additionally, there is subtle high frequency tapering of the Width content to avoid overemphasizing harsher HF tones.
