The Model 1150 Masterbay S Mastering Interface from SPL is a processing hub where you can connect up to four stereo processors, and add additional and orderly control to the mastering and audio sweetening process.
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 on projects, since you can set up the audio path according to a specific production without having to change anything until the production is finished; this 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, often resulting in the need for loudness compensation after processing, comfortable fine adjustment of input and output levels (level matching),or an adequate level control to dynamically fade the signal.
The MasterBay S fulfills all of these requirements and goes even a couple of decisive steps forward. Its all-in-one simplified 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 time.
Using the MasterBay S as the central interface for all your hardware gear mimizes the actual conversions taking place, regardless of the number of processors used. Due to its engineered quality, the MasterBay S not only pampers the signal, but also becomes a key element in the audio production stage where it is put to use.
