ANNEXE D: Digital Level Processor (DLP).The digital level processor (DLP) is an additional feature included in the PHOENIX MOBILE thatwas developed to improve the quality of the processed signal by modifying its level. Accordingto the configuration, the DLP will make it possible to:• increase the program signal level.• apply compression to the program signal.• apply a limiter to the signal.• apply an ambient noise reduction effect.By default, the unit leaves the factory configured with a pre-programmed profile, called Linear,although the user can create, edit and eliminate new profiles in Menu >> Advanced >>Applications >> DLP Design.While it is not an especially complex process, the creation, configuration and modification of aDLP profile is an operation that is seldom performed. For this reason, we have included it in anappendix of the manual. Moreover, the ability to read and understand DLPs is only required bytechnical personnel responsible for the technical support of the equipment; these technicians,then, will be responsible for correct DLP configuration.The activation of digital level processing is such an elementary function (easily accessible tousers whether they are technically qualified or not), that it has been described previously inthose points of the manual where its use is recommendable, and thus is not treated in thisannexe.Detail of DLP Design MenuThe Linear profile supplied by default with the unit is not specifically useful, in the normaloperation of the codec, inasmuch as its configuration basically results in the input signals beingprocessed so that they retain the same levels at the output as they had on the input side (seenext figure). This default profile cannot be edited, but it serves as a reference to the user for thesubsequent creation of other profiles according to the specific needs of each application andclient.AEQ PHOENIX MOBILE98
