Mix Bus Bundle - MBT / 5057 Orbit Summing Mixer

Complete Analog Mix Bus Workflow
Combine analog summing and master bus processing in one streamlined signal chain, taking a mix from individual stems through final stereo enhancement.

Rich Analog Summing
Bring multiple tracks or stems together through the ORBIT’s Class-A analog signal path for a more cohesive and dimensional mix.

Advanced Mix Bus Processing
Shape the summed stereo mix with the MBT’s EQ, compression, stereo width, filtering, and harmonic processing.

Custom Transformer Character
Both units use Rupert Neve Designs transformer technology, adding musical harmonic character and analog depth throughout the mix path.

Flexible Tonal Color
Use Silk and transformer saturation controls across the signal chain to add warmth, presence, weight, or additional harmonic texture.

Mix Glue and Dynamic Control
The MBT’s Color Comp can help bring the summed mix together while maintaining control over punch, movement, and overall dynamics.

Powerful Tone Shaping
Fine-tune the overall balance with musical low- and high-frequency EQ, helping add body, clarity, or polish to the finished mix.

Enhanced Stereo Image
Expand the perceived width of the mix while keeping lower frequencies focused for a spacious yet controlled stereo presentation.

Creative Saturation Options
Combine the ORBIT’s transformer coloration with the MBT’s Super Silk and Zener Drive processing for everything from subtle enhancement to more pronounced analog character.

Mix and Master with One Hardware Chain
Create a complete analog finishing path that can handle summing, coloration, compression, EQ, stereo enhancement, and final output control before returning the mix to the recording system.
