Klipsch Optimize Mode
Klipsch Optimize Mode allows you to easily integrate your Klipsch Reference and Reference Premiere speakers seamlessly with your Onkyo AV receiver. Klipsch and Onkyo teamed up to implement the precise crossover values for specific new Reference Premiere speakers. Now, you can simply select the model speakers you’ll be using for each individual channel, and the optimized crossover setting will be automatically applied.
Take the room out of the equation
State-of-the-art Dirac Live Room Correction technology unlocks your loudspeakers' full potential, improving audio performance across the full frequency band without additional upgrades. Dirac Live automatically calibrates sound in your room using either your smartphone and the included wired mic or virtually wireless with the Dirac Live PC or MacOS* application and a 3rd party USB mic (not included). Now, you'll get a more accurate measurement of your surround sound system's positioning to be more precise and balanced, providing a better result with the increased upper limit of delay time from 20 to 50 milliseconds.
