User manual ART 405

[. . . ] And whether they are installed in a club, a hall, a restaurant, a church, an arena, an office, a recreational facility, or even if they are part of a portable PA with distributed speakers, systems like this have a unique potential. It is possible to remotely adjust the volume of every amplifier or powered speaker, either in groups or individually, with a zone distribution mixer like the Model 405. Basically the input of the Model 405 is connected to the PA mixer's line-level output (the Model 405 will accept the output of two mixers) and the power amps and/or powered speakers are connected to the Model 405s zone outputs. Now it is possible for the operator to adjust the volume of all the system components with just one set of controls. [. . . ] You may repeat the process with INPUT SOURCE 2 for an additional mixer or other audio source. c) Using balanced XLR cables connect the Model 405 OUTPUT ZONE connectors to the inputs of the appropriate power amplifiers and/or powered speakers. d) In most operating situations the MONO/STEREO button would be in the MONO position. Firstly, stereo separation works well in the home where the listener can be situated more exactly between the speakers to hear each one equally. But away from that environment in a club, restaurant, office, rec hall, etc, listeners too often find themselves closer to one speaker than the other. Now stereo separation can cause a situation where they predominantly hear just part of the program e. g. , guitar but no keyboard or vice-versa. With the system in Mono mode, all of the program music comes out all of the speakers. Secondly, if you connect a mono source to one of the Left or Right SOURCE INPUT connectors then switch one or more zones into STEREO, that source will only come out the amp/speakers connected to the Left or Right ZONE outputs. People not situated close to those speakers may not be able to hear that source at all. e) Adjust the SOURCE level controls to produce the desired volume in each area. If a CLIP light fires, reduce either that ZONE s level control, or the output of the signal source to prevent distortion. f) The SIGNAL light in each ZONE indicates the presence of input signal there. g) SOURCE INDICATOR 1 and 2 lights tell you which INPUT SOURCE is receiving signals.
