Auditorium Installation
A typical auditorium application requires the use of multiple inputs and outputs, as well as audio equalization and signal delay, to provide a pleasing audio experience. The PSR1212 handles these tasks perfectly.

The auditorium diagram (Figure 7.1) illustrates a typical auditorium layout, with locations of microphones, speakers, and seating areas. Typical audio scenarios include on-stage speaking; singing and/or musical instruments; and pre-recorded music sourced from a CD or tape player. You can configure a preset for each scenario, using the PSR1212’s filters to tailor the sound for a natural, balanced response.

Auditorium applications using constant directivity horn speakers located high at the front of the room are enhanced with the PSR1212’s CD Horn EQ. This feature compensates for the inherent 6dB/octave high frequency rolloff typical of CD horn drivers. You can program this function for each preset you use for auditorium applications.

Audience members seated underneath the balcony are shielded from some of the output from the horn speakers located at the front of the room. To compensate, fill speakers are used in the ceiling underneath the balcony overhang (see Figure 7.1). To eliminate the imbalance caused by sound reaching a listener’s ears at different times from the fill speakers and the horn speakers, you can program the PSR1212 to introduce a delay to the fill speakers. The PSR1212’s G-Ware software can calculate distances in feet and meters to help establish the amount of delay required.
