2.2 StepArray column models2.2 StepArray column modelsTable 1 on the next page and table 2 on page 13 give an overview of the StepArray models characteristics. Acomplete description of the technical characteristics can be found in sections 14 and 15.15m 30m 35m 68mSA100PSA180PSA250PSA400P2.5m3mFloorFigure 6: Listening zones (P-models)4m 28mSA180SSA250S2.6m3.8m22m10°FloorFigure 7: Listening zones (S-models)Columns whose name ends with a «P» (SA100P for example) are designed for horizontal audience areas,whereas column whose name ends with a «S» are designed for tilted audience areas (or with balcony).2.3 StepArray specificity: shared electronicsOne of the advantages of using external electronics is that several columns can be connected (via their amplifier) tothe same UT26 processor.A UT26 processor features 6 analog symmetrical outputs. Therefore a single UT26 processor can be used to deliversignals for:• a 6 channel column,• one or two 3 channel columns.Moreover, a UT26 processor can be connected to one or several StepArray amplifiers (to feed several columns withthe same signal). In this case, the inputs are simply daisy chained to the amplifiers (see section 9.1 on page 22).Last update: December 23, 2010 11
