Turn the knob to set the required delay RELATIVE to delay 3 In a similar manner the absolute value can be displayed and adjusted for the other reference output delay 1 and its associated linked output delay 2 Confirmation of the absolute delay time can be obtained by exiting the relative mode and selecting delay display in the usual manner 29 Linking 804 Only 30 Press Relative Press Delay4 SYSTEMS Exit relative mode BEH H If the other reference output has been chosen as delay 2 rather than delay 3 then the above description of operation is still identical but with delay outputs l and 2 as reference pulling delays 3 and 4 with them The indicators will confirm this action and select delay 4 Stereo links are also active in relative mode and may cause additional delays to be dragged by the reference In the relative display mode both positive and negative delays are indicated to show true displacement It is quite likely that you will want to select the units to display and adjust in distance rather than time so that the setting up is much more intuitive to what is being measuring Although seemingly complex in description the relative mode Is simple to use after a short time Remember The red LED shows the reference delay a flashing green LED shows a linked delay which will also be dragged when its reference is moved Applications 14 0

Applications 14 1 Time Correction for Audience Distances 14 2 Time Correction for Speaker Dnver Placement In any large public auditorium it is necessary to arrange the loudspeaker system in clusters which are distributed around the arena to help obtain a more uniform distribution of sound level For any given position within the arena a listener will be hearing a combination of both the direct sound from the stage and that from the nearest distributed cluster Because the speed of sound air is considerably slower than that of the equivalent electrical signal in the cable the audible sound from the nearest cluster will be heard by the listener slightly before that arriving from the stage The time delay between these two needs to be compensated for otherwise the listener will hear anything from a slightly unintelligible sound to one that is totally indistinct Both the TCS 803 and TCS 804 can be used to cure this situation by connecting one of its delay outputs to the distributed cluster The delay time needed will be equivalent to the distance between the loudspeakers Remember that the speed of sound at 20 C 15 approximately 343 meters per second This gives you a rule of thumb of 1 msec ft or 3 msec metre W hen using multiple delay clusters or when working stereo it will be up to the user to decide whether it is better to use the TCS 803 or the TCS 804 switched to mono or dual channel mode When a loudspeaker so
