NE OUT 1 Fig 5 1 Example of a studio playback application 5 2 1 Using the amplifiers as independent power amplifiers In addition to the joint control of all channels via the MAIN input each of the four power amplifiers can also be used independently The AUX IN inputs in combination with the BALANCE controls serve this purpose If the BALANCE control is set to its clockwise stop position position AUX the MAIN signal is muted only the input signals applied to the AUX IN input are routed to the power amplifier By configuring the amplifiers as completely independent power amplifiers you can insert up to four independent stereo programme sources thus four different and individual mixes for up to four musicians can be created As with a stage monitor system you can give each musician a specific configuration of instruments and create a personal mix for him or her that is musically inspiring Or you can set up different signal paths for the interpreters in a conference system Configure sub groups or create pre mixes using the effects and or monitor facilities of your mixing console Fully turn up the BALANCE control and connect the AUX inputs of the BEHRINGER POWERPLAY PRO to the corresponding monitor sub group or single outputs of the mixer OUT 1 OUT2 OUT 3 bes H MONITOR PATHS AUX IN 2 AUX IN 3 AUX
13. al OUTPUT LEVEL controls are used to adjust the desired channel volume 5 2 Using the AUX IN inputs Basically the AUX IN inputs are used to add an additional input signal to the master signal with the corre sponding BALANCE control determining the volume ratio between the two signals The aux function supercedes the previously required monitor mixer and allows for an application that is frequently used in practice Example suppose a vocalist wants to record a vocal track that is to be added to already existing instrumental tracks Up to now it has been common practice that the vocalist listens to the playback by pressing a headphone pad against one ear while controlling his her own voice with the other free ear This kind of application can be achieved much more easily and conveniently with the POWERPLAY PRO The playback signal is inserted via the MAIN inputs and the preamplified vocal signal is applied to the AUX connector The associated BALANCE control is adjusted so that the vocalist hears a perfect mix of both backing tracks and vocals with the OUTPUT LEVEL control determining the overall volume level Owing to the four independent channels of the POWERPLAY PRO four individual mixes for four musicians can be achieved If this is not enough you can interface and link any number of POWERPLAY PROS using the MAIN outputs 12 5 APPLICATION HEADPHO
