Rupert Neve Designs MBT (Master Bus Transformer)

Introduction:
Audio transformers have been at the core of Mr. Rupert Neve's audio circuit design philosophy for over six decades. They're an integral part of Rupert Neve Designs' products, especially the MBT. Packed with these transformers, the MBT offers a wide range of options to enhance, shape, and transform audio sources, making it a versatile tool for musical coloration. Whether applied to a full mix, groups, stems, or individual sources, the MBT combines legendary tonal quality with flexible controls.

Tonal Magic with HPF & Shelf EQ:
The MBT features a variable high-pass filter (HPF) that spans from 100Hz to 15Hz, ideal for managing low frequencies in a mix. It also includes a new 2-band Shelf EQ section with adjustable LF and HF bands, providing +/- 9dB of gain control. The LF band shapes low-end weight and power, while the HF band adds shine and clarity. Experimentation with the interaction of these sections is encouraged.

Breathe New Life with the Color Comp:
The Color Comp introduces an optical compressor design that emphasizes non-linear distortion and character to enhance audio depth. You can set the compressor ratio from subtle 2:1 to dramatic 5:1. A variable high-pass sidechain filter and Blend control offer flexibility in shaping compression. The Color Comp introduces harmonic content even with minimal gain reduction, and its release time ranges from 100mS to 1.5S for varied compression effects. It also provides 20dB of Class-A makeup gain for further harmonic enhancement.

New Dimension with Width:
The Width section enhances the stereo spread without losing low-end focus. It has an additive width control with a broader range and a variable high-pass filter (HPF) to adjust width content. Subtle high-frequency tapering prevents harshness in the widened soundstage.

Control Harmonics with Super Silk:
Super Silk takes the beloved Silk circuit to a new level. It includes independent Red, Blue, Harmonics, and Zener Drive controls. Silk Red emphasizes upper mid and high-frequency harmonics, while Silk Blue enhances low and low-mid frequency harmonics. The Harmonics control saturates the MBT's custom interstage transformers, offering unique blends and balances. The Zener Drive introduces asymmetrical soft clipping for a more aggressive tonality.

Drive and Control Levels with I/O Amplifiers:
The MBT incorporates Class-A input and output amplifiers to ensure optimal gain staging, interstage transformer operation, and precise level matching. Output amplifiers drive custom output transformers for line balancing and isolation.

In summary, the MBT is a versatile tool for audio professionals seeking precision and musicality in sound shaping. Whether you're looking to EQ, compress, manipulate harmonics, enhance stereo width, or manage levels, the MBT empowers you to explore exciting and creative new possibilities in your audio production.
