威ULTRAPATCH PRO PX2000Welcome to BEHRINGER!Thank you very much for expressing your confidence in BEHRINGER products by purchasing the ULTRAPATCH PROPX2000.A patchbay allows to patch the audio signals of most components in your studio from a central point and send themto other units,which makes your entire cabling better structured and is indispensable for professional work.If youwant to use your studio as effectively as possible then it is preferable to use a complete patchbay wiring scheme,buteven less sophisticated patchbay solutions will benefit smaller studio configurations.1.PATCHBAY CONFIGURATIONThe majority of commercially available patchbays include two rows with 24 phone jacks each in a 19"1 HU rack panel.On the rear,either a corresponding number of phone jacks or contacts for soldering signal leads can be found.Eachgroup of four of these phone jacks forms one module.The configuration of some patchbays can be changed byinserting jumpers or turning individual modules.With the BEHRINGER ULTRAPATCH PRO PX2000 you own an easy-to-use 24-patchbay offering phone jacks throughout,which can be operated in four different modes simply by setting a switch on the upper panel (example:module 17):1.1 ParallelIn this mode,all terminals of one module are interconnected.This configuration doesn't make sense at first glancebut is used to split up and send one audio signal (e.g.aux send)to several destinations (e.g.effects devices).1.2 Half-normalled冠冠In this configuration,the contacts of the two jacks on the rear are interconnected.When you insert a plug into the upperfront jack,the signal routed through the rear path is not interrupted.Only when the lower frontjack is used will the rear-panel route be split up,so that the two upper and the two lower phone jacks are connected to one another.Thisconfiguration is called "input break'and is used mainly for insert paths.So you can easily patch the signal from amixing console channel at the patchbay without interrupting the signal flow in the channel.1.3 NormalledHere,and in contrast to the "half-normalled"setup,the signal route of the rear phone jacks is interrupted when youinsert a plug both into the upper and lower front jacks.1.4 OpenThis mode is used to connect devices such as sound modules or CD players having no inputs of their own.Thissaves space,as you can route the left and right outputs to one module (left-top;right-bottom)or patch two devicesto one module (top and bottom).Effects devices and 2-tracks can be configured this way,so the inputs and outputsare positioned on top of each other.Basically,the inputs are routed to the bottom and the outputs to the top rear-wall connectors.Avoid routing digitalsignals over a patchbay as the pulse signal used for the transmission of such signals causes heavy interference inanalog signals.Additionally,nommal patchbays change the impedance of the digital cable route,which causesinterference in the digital path.Use the BEHRINGER ULTRAMATCH SRC2496 specifically des
