PathFinder Version 4.22 User Guide10. DIMMING10.1 IntroductionComprehensive dimming facilities are provided. This form allows, per destination: -• ASSIGNMENT Displays the currently configured sources to this panel.• MODEDetermines whether the default mirror dimming is to be applied foreach source, or whether no dimming (null dimming) is to be applied.Automatic mirror dimming ensures that when a full duplex route isestablished (i.e. panel A is connected to panel B and vice versa),attenuation of the specific crosspoints is applied.The term mirror refers to the fact that on a source/destination matrixgrid (crosspoint diagram) the A-B and B-A duplex path is a singlecrosspoint mirrored about a diagonal.• GROUPFor instances where mirror dimming does not perform adequately,due to for example acoustic coupling between physically adjacentpanels, a list of source-destinations (crosspoints) may be activatedto dim (attenuate) specific routes in the system.• GROUPAllows the specific source-destination lists to be set-up. Up to 5MEMBERS Dim-Groups may be set-up per panel, each with 32source/destinations.• DIM LEVEL Sets the attenuation applied to the crosspoint routing audio to thispanel when dimming is applied. The dimming level may be set inthe range 0 to -37dBu in 1dB steps.Trilogy Communications LimitedIssue 1Page 63 of 63
