New Make Noise 208hp 7U 4 Zone CV Bus Case and CV Big Bus!

Press release follows:

Make Noise is proud to announce our new 208hp 7U 4 Zone CV Bus Case and CV Big Bus!

The 208hp 7U 4 Zone CV Bus Case arrives ready to be put to use with your modules, patch cables, and inspiration. The powder coated metal construction offers excellent mechanical durability. The mounting rails have been updated to black anodized tapped strips, replacing the sliding nut design of previous versions of the case. The lid is removable and can be closed with the system fully patched. The bus boards now includes 31 shrouded headers for connection to modules. The sleek matte black finish was selected to match our line of Black & Gold modules, and it looks great with just about any module installed. This finish will wear nicely, showing the story of your modular synth's travels over the years.

The Make Noise 4 Zone Power system is a new approach to accommodating the ever growing universe of Eurorack modules. The multi-zone power solution is like having multiple independent power supplies in a single case. This allows for isolating noisy modules from noise sensitive modules. Each Zone features isolated +12 VDC and -12VDC supplies and a dedicated ground return path. Included are 31 power shrouded connectors to help prevent incorrect installation. The total available power available is +12VDC @ 4A, -12VDC @ 2.4A, and +5VDC @ 1A.

The CV Bus is a more functional approach to the “multiple” utility of the modular synthesizer. The CV Big Bus is an evolution of the original CV Bus design from 2013 for Alessandro Cortini's personal Make Noise system. In an effort to accommodate the increased modulation density of the New Universal Synthesizer System, the CV Big Bus doubles the channel count from 4 to 8. These 8 channels are distributed across the center of the system, allowing for quick, clean, and intuitive patching. The numerical indicators are illuminated, providing visual indication of channel number, level, rate and polarity for up to 8 signals to be shared throughout a patch. This distribution method is unlike the typical multiple since the control signals will appear beneath their potential destinations, resulting in less cable mess. The color coding and visual indication makes navigating complex patches easier and more intuitive. Typically, the CV Bus would be used to share the most important control signals in a patch, such as your clock, modulation, sequence, and audio signals - any type of signal the system creates may be shared!

A high quality Stereo Line Driver converts modular synthesizer signal levels to the commonly used Line Level. There are mini-jack inputs for Left or Mono, and Right for Stereo, a single master volume control, as well as a stereo line output pair. The left output doubles as a TRS ⅛” headphone output. These outputs are capable of driving a long cable out to a PA System or a set of Headphones. They are AC coupled with a built-in limiting circuit (with visual indication) that prevents damage to ears and PA system when the patching gets experimental.
