SETUP WIZARD EQ

EQ (or equalization) is designed to either make corrections to the audio signal based on frequency anomalies in a particular room, or to color the audio signal to adjust for a specific application. Many of these application-style EQs color the signal path to represent the EQ curve that would be typically associated with a style of music or a specific application (such as speech). After speaker cabinet selection, the IPR™ DSP will ask the user if EQ is required (Fig. 7). If “Yes” is selected the user will be able to scroll through several pre-designed EQ curves that will give the user the general characteristics associated with one of the following selections (Fig. 8):

Rock

Dance

Thump

DJ

Contemporary Worship

Speech

Setup Wizard Remote Speaker Delay

Delay is often required for systems with remote speakers. Occasionally remote speakers are required for larger audiences. These speakers can provide additional coverage in areas the main PA speakers do not adequately cover. Unless the remote speakers are delayed properly the audience will notice a time difference between the primary source (main PA) and remote speaker. This time difference will be perceived as an echo and will cause an undesirable listening environment. The IPR DSP amplifiers offer up to 120 mS of delay per channel, enough to position the remote speakers up to 136 ft from the primary PA speakers (Fig. 9).

When the amplifier is configured to drive a Mono, two-way speaker system, the delay adjustment changes both channels simultaneously. Once in the delay screen, turn the navigation encoder to increase

or decrease the amount of delay. The screen displays the delay in milliseconds, feet and meters (Fig. 10).
