SPL MasterBay S Patchbay Details

The SPL MasterBay S Patchbay is a patchbay and switch matrix. Compare, switch, route, trim your hardware gear in the mix buss or in mastering. MasterBay S offers four balanced insert loops with gain trims, parallel mix, individual and all bypass switches as well as a master fader, DAW return, auto bypass and loudness compensation.

The classic patch bay allows you to easily route signals between different signal sources, processors and other audio gear. All connected devices can be tapped at any point in the signal path by simply making the adequate connections in the patch bay. This can be very practical when working in projects, since you can set up the audio path according to a specific production without having to change anything until the production is finished. That is frequently the case during mixdown.

However, in the mastering stage the needs of an engineer often go well beyond this. Even a direct A/B comparison between two processors or two different signal paths can prove unfeasible with a patch bay. Not to mention loudness compensation after processing, comfortable fine adjustment of input and output levels or an adequate level control to dynamically fade the signal.

The MasterBayS fulfills all of these requirements and goes even a couple of decisive steps forward. Its comfortable yet flexible switching and control functions make it easier to achieve the best results with the available equipment. Innovative and pragmatic functions, conceived to simplify and improve the comparison process, give you a qualitative edge in mastering applications, while saving you time. Using the MasterBayS as central interface for all your hardware gear reduces to the minimum the actual conversions taking place, regardless of the number of processors used. Due to its high engineering quality, the MasterBayS not only pampers the signal but it also becomes a key element in the audio production stage where it is put to use.

Its cutting-edge and clever features on the one hand and state-of-the-art conception and manufacturing on the other, make the MasterBayS a typical SPL unit — innovative, handmade premium quality from Germany.
