Distributed loudspeaker systems need their own set of connectors that are similar to what is done for power systems. These systems typically use 25V, 70V, 100V, 140V and 200V distribution schemes. Each loudspeaker typically can select 4-5 Power taps, such as 0.125W, 0.25W, 0.5W, 1W, 2W or 7.5W, 15W, 30W, 60W. These are then connected to amplifiers with ratings ranging from 10W to over 2000W. This is similar to the design requirements for branch circuits on a Panelboard.
This new "Loudspeaker Connection" should have the following parameters:
"Loudspeaker - Loads" as a Category.
"Voltage" selectable from 25V, 70V, 100V, 140V and 200V with others defined by the user in a similar fashion to Power Systems.
"Load" calculated using line losses from the cable and the tap selected for each of the attached loudspeakers
"Loudspeaker - CV" (CV=Constant Voltage) as a System Type.
"Loudspeaker" as a Load Classification.
