1. Headzone Technology e Q apz2one beyerdynamic 4 5 Why head tracking 1 Loudspeakers do not move Loudspeakers are installed at fixed positions within a room and provide a sound impression that is spatially stable The loudspeaker does not change its position with the listeners every movement but will sometimes be in front of them next to them or behind them depending on their movements position In contrast headphones are attached to the user s head which means that a signal coming from the right hand earpiece of the headphones will always remain to the right of the user because the headphones also turn when the listener turns his head Since we are not used to moving loudspeakers our brain is constantly reminded of the fact that we are just wearing headphones Headzone solves this problem with the development of new patented technology With the help of an ultrasonic head tracker the system continuously tracks the head position of the listener and adjusts audio reproduction accordingly For example if the user pla ces a virtual loudspeaker in the front right hand corner of the room it will always remain in that position The user can turn towards or away from the loudspeaker no matter how he moves the loudspeaker does not move and remains at the same virtual location This allows for a striking degree of reality in surround reproduction which could not be achieved until now as at a certain point the brain forgets

DT 770 PRO HT or DT 880 PRO HT and Headzone Rail Head tracker does not work properly small operating range or head tracker jumps around Reflections of the ultrasonic signal lead to misinterpretation in the receiver Ground loop On some DVDs the LFE channel is 180 out of phase Mixed with the L R channel this leads to the observed phenomenon Your Headzone device is probably in the upload mode due to a DSP firmware update that was not properly finished As told in this manual Headzone automatically stores all settings within the hardware In very seldom cases it can happen that you turn off your Headzone device during the process of storing or before new settings have been stored When configuring your Headzone device to the lowest possible sampling rate 32KHz your Mac will not properly re initialize this setting when you plug in Headzone the next time Your Mac will configure Headzone to the highest possible sampling rate 96KHz instead while internally working with 32KHz This problem is known as the chipmunk bug on Power PC based Mac computers and is not derived by Headzone but by the native Apple Core Audio drivers This problem does not exist on Intel Macs and will probably be solved with future updates of Mac OSX 37 ADZO beyeraynamic Adjust the scale of the head tracker compensation according to your needs see chapter 8 5 6 Viewing and customising the head tracker
