The Manley Mastering Backbone Insert is built with a unique electronic topology that maintains a fully balanced signal path through 95% of the console. All other designs require the balanced signals to be converted to unbalanced before sections that, for example, allow you to boost or cut level, then inversely need to be converted back to balanced to feed the outside world. In other words, this new topology not only does it in one stage rather than three or four stages, but also does it as cleanly and quietly as any single stage could that Manley know of, including fully discrete approaches.
This topology also provides better common mode rejection and power supply noise rejection than conventional approaches. This is significant especially in the "Sum-DifferenceË functions. Each of the 10 gain blocks and all of the switches are on connectors, which means if the unit ever requires service, repair can likely be done quickly without the need for a technician or soldering iron; just a medium-small Philips screwdriver. No expense was spared in the quality of the parts, so one should expect many years of continuous professional use.
