Denon has chosen, for many of its acclaimed A/V receivers, with what we feel to be the most
advanced and sonically beneficial Auto Setup and Room Eq system currently available, the
MultEQxt system from Audyssey. Introduced first on the AVR-5805, MultEQxt is now available
on the AVRs-4806, 4306, 3806 and the upcoming AVR-2807CI (March ’06). Due to its
complexity and differentiation from competitors systems, there have been many questions to
what MultEQxt

Response (FIR) filters for equalization that use sevral hundred coefficients to achieve much higher resolution in the frequency domain than parametric bands. Furthermore, by their nature, FIR filters simulatneously provide correction in the frequency and time domains. The second major difference is that MultEQxt combines multiple measurements to create equalization filters that better represent the acoustical problems in the room. Most other methods only perform a single point measurement

loudspeakers in the system. The subwoofer in this case is equalized to flat as is the case for all the settings described above. Finally, the ‘Manual’ setting is a traditional Graphic equalizer that does not use the MultEQxt filters. However the ‘base curve’ that was measured during the Auto Setup process, can be copied to the Graphic EQ, where you can then make adjustments to your personal tastes, again no other properties of MultEQxt are applied with this setting. 5. Why does MultEQ

receiver, the number of points that can be measured is the only difference in the MultEQxt system. (i) AVR-5805 and 4806 offer 8 points of measurement (ii) AVR-4306, 3806 and 2807 offer 6 points of measurement 9. Does the microphone have to be placed in each seat? No. The ideal calibration consists of 6–8 measurements that encompass the listening area. It is important to have the microphone in the “main” listening position for the first measurement so that the delays are calcula

13. Does MultEQxt compensate for loudspeakers placed behind a projector screen? If the calibration is performed with the screen in place, MultEQxt will automatically create filters for behind-the-screen loudspeakers that compensate for the screen loss. 14. What happens to the MultEQxt settings when the parameters are changed? MultEQxt corrects for room acoustical problems. Changes in the tone controls do not change the filter performance. They do change the tonal balance based on the
