13. 20 C If one of these delay values is not zero the red LED on the DELAY button lights up a Use the Input Delays to create delay lines Delay lines are speakers which are set up behind one another The delay times of the speakers sound propagation is compensated using delays The purpose of delay lines is to ensure that the sound from the speakers near the stage reaches the listeners in the back of the audience simultaneously preferably with the sound from the speakers in the rear audience area You can separately adjust the delays of up to four input channels with every channel having a total available delay of 200 ms or 68 6 m Because a delay of 0 02 ms is already set up in the LSBlock ACCESS High the available delay time when using this LSBlock is reduced accordingly by this amount b Use the Output Delays to compensate differences in delay time of the positioned speakers for example from flown tops to standing bass speakers stage edge speakers to the main system etc You can separately adjust a total of 4 output channels Out 1 and Out 2 share 20 ms or 6 86 m delay time Out 3 and Out 4 also share 20 ms or 6 86 m delay time These values decrease if there is already a delay set in an LSBlock If you select a delay of 5 ms or 1 715 m for Out 1 then there are another 15 ms or 5 145 m available for Out 2 The same also applies for Out 3 and Out 4 The value stated next to Avl indicates how much delay time is still ava
