Rupert Neve Designs is proud to introduce the MBT Master Bus Transformer, a remarkable piece of engineering that puts Rupert Neve's decades of experience and passion for audio design into action. Every feature has been crafted with one goal in mind: to take your studio productions to the next level.
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. Equally at home on a full mix, groups, stems or individual sources, the MBT pairs undeniably legendary tonal quality with an immensely flexible set of controls to shape your sound.
Rupert Neve Designs MBT Master Bus Transformer Features
Create Tonal Magic with the HPF & Shelf EQ
First in line is a smooth high pass filter with a fully variable frequency selection control. The HPF extends from 100Hz all the way down to 15Hz, an especially helpful area to manage on a full mix that needs to be as loud as possible.
Next up is the all-new 2-band Shelf EQ section - with 3 octave ranges, gentle slopes and minimal phase shifts, this EQ 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.
Each band has +/- 9dB of gain control, with the LF EQ corner frequency variable from 30Hz to 240Hz and the HF EQ corner frequency variable from 3kHz to 24kHz. The LF band is excellent at either taming or accentuating low-end to give source material an exacting amount of weight and power. The HF band provides a wide range of corner frequencies to choose from, allowing adjustments to be made from the upper midrange all the way up to the very top end, giving tracks extra shine and clarity.
One exciting aspect of using the MBT is discovering how the different sections can interact with each other. Sometimes the EQ can be dialed in first, other times it can be left alone until the other sections are dialed in. One thing is certain: the MBT encourages experimentation at every turn.
Breathe in New Life with the Color Comp
With an all-new optical compressor design, the Color Comp excels at accentuating the non-linear distortion and “colorful” characteristics of the Opto cell to bring source material a new sense of life and depth.
The compressor ratio can be set to a low (2:1) ratio for subtle & smooth compression or high (5:1) for much more dramatic behavior.
The variable high pass side chain filter removes the low frequencies from the compressor side chain circuit, allowing low-end information to pass through the compressor untouched while the compressor focuses on the rest of the signal. With a sweepable range from 20Hz all the way up to 350Hz, this is a highly flexible tonal shaping control providing the ability to leave the low end intact while taming or squashing the rest of the source material as needed.
The Color Comp also contains a Blend control, making it easy to use the compression circuit in parallel with the uncompressed source material. This can be especially useful when wanting to dial back the harmonic content, dynamic range reduction, and transient squashing from more extreme compressor settings.
The threshold is variable from 0dBu to +24dBu, with a gain reduction LED illuminating when the signal passes the threshold. However, the Color Comp also introduces audible non-linear harmonic content even with just a touch of gain reduction – as such, it’s highly recommend to listen to the Color Comp engaged even when no gain reduction is visible, in order to discern the amount of tonality that it introduces. The pleasing nature of this harmonic content will become even more apparent as the compressor settings become more extreme.
The release is variable from 100mS to 1.5S. By dialing in higher ratios and faster releases it is possible to get the color comp to actively “pump” with the attacks, whereas with slower release times it will operate in a much smoother manner.
