03D Applications 81 Sound Localization & Sound Image Control (Using Hass Effect) Using the bus assign, the main PA sound can be positioned to match that of the sound source. Delays in multiple speaker systems can be compensated using the bus output delays (Hass Effect). In a large or medium-sized church or hall with rear or side speakers, where the sound image needs to direct listeners towards the presenter or sound source, adding a small delay of between 10 and 20 milliseconds to the rear speakers gives the impression that the presenter is actually located in front, not behind (Hass Effect). Each 03D output can be delayed by up to 40 milliseconds. To achieve the Hass Effect, a small delay must be used in addition to the delay used to compensate for speaker distance. For example, if the distance between the front and rear speakers is 30 meters, the speaker distance compensation delay will be 87 milliseconds (30/344 = 0.087, where 344 is the speed of sound). To this a small delay of between 10 and 20 milliseconds should be added to achieve the Hass Effect. Formula for setting total delay is (distance between front and rear speakers/344) + 10-20 ms Front Rear 03D Presenter PHONES 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 ST IN MONITOR OUT PHONES PAD 26dB 26dB 26dB 26dB 26dB 26dB 26dB 26dB SOLO/ 2TR IN -16 -60 -16 -60 -16 -60 -16 -60 -16 -60 -16 -60 -16 -60 -16 -60 +10 -20 +10 -20 +10 -20 +10 -20 +10 -20 +10 -20 +10 -20 +10 -20 +10 -20 +10 GAIN -34 +10 GAIN -34 +10 GAIN -34 +10 GAIN -34 +10 GAIN -34 +10 GAIN -34 +10 GAIN -34 +10 GAIN -34 GAIN GAIN GAIN GAIN GAIN GAIN GAIN GAIN GAIN 0 10 LEVEL 0 10 LEVEL SETUP SCENE MEMORY UTILITY MIDI MIDI REMOTE SCENE MEMORY UNDO/ REDO SOLO SOLO DIO GROUP/PAIR SOLO SETUP AUTOMIX STORE RECALL CHANNEL CONTROL DELAY/Ø DYNAMICS PAN/ROUTING VIEW EQ LOW LO-MID HI-MID HIGH EQ LIBRARY EQ FLAT AUX 1 FADER MODE AUX 2 AUX 3 AUX 4 FUNCTION SEL CH FADER EFFECT 1 EFFECT 2 METER MIXING LAYER 1-16 17-24/MASTER 1 2 3 4 5 17 18 19 20 21 FADER STATUS 6 22 SCENE MEMORY USER DEFINE FADER 1-8 9-12 13-16 ST IN EFFECT RTN L STEREO R CLIP -3 -6 -9 -12 -15 -18 -24 -30 -36 -42 -48 USER DEFINE 1 2 3 4 ENTER CURSOR PARAMETER 1 2 7 23 8 24 9 AUX1 10 AUX2 11 AUX3 12 AUX4 13 BUS1 14 BUS2 15 BUS3 16 BUS4 ST IN EFFECT RETURN ST OUT SEL SEL SEL SEL SEL SEL SEL SEL SEL SEL SEL SEL SEL SEL SEL SEL SEL SEL SEL ON ON ON ON ON ON ON ON ON ON ON ON ON ON ON ON ON ON ON 6 6 6 6 6 6 6 6 6 6 6 6 6 6 6 6 6 6 6 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 5 5 5 5 5 5 5 5 5 5 5 5 5 5 5 5 5 5 5 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 20 20 20 20 20 20 20 20 20 20 20 20 20 20 20 20 20 20 20 40 40 40 40 40 40 40 40 40 40 40 40 40 40 40 40 40 40 40 60 60 60 60 60 60 60 60 60 60 60 60 60 60 60 60 60 60 60 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 1 17 2 18 3 19 4 20 5 21 6 22 7 23 8 24 9 AUX1 10 AUX2 11 AUX3 12 AUX4 13 BUS1 14 BUS2 15 BUS3 16 BUS4 ST IN EFFECT RETURN ST OUT 03D Delay 10-20 ms Delay 10-20 ms Delay 10-20 ms Delay 10-20 ms Listener Delay Stereo out Stereo out Front Bus out Bus out Bus out Bus out Rear Yamaha 02R & 03D Applications Guide
