1. Setting the Surround Delay For Dolby Surround AC 3 as opposed to the conventional Dolby Pro Logic technol ogy it is unnecessary to set the time delay between front speakers and surround speakers The only thing you should consider is the difference between the front speaker listener distance and surround speaker listener distance 1 Press the DELAY TIME button repeatedly until the desired delay time is displayed The factory set default is 5 ms millisec onds Each time the DELAY TIME button is pressed the time increases by 1 ms You can set a delay time within the range of 0 to 15 ms DELAY TIME Er A rule of thumb is that it takes 1 ms for sound to travel one foot For example if the front speakers and the surround speakers are located the same distance from the listening position you should set the delay time as 0 If the front speaker listener distance is one foot longer set the delay time to 1 ms and so on Note If your surround receiver s delay time has been accurately set for Dolby Pro Logic Surround play make the ED 901 s delay time 15 ms shorter than that time If you have changed the speaker arrangement change the speaker output setting as appropriate both on the ED 901 and on the surround receiver The settings of these two are independent of each other 11 Operation Re EQ is licen2.
