1. T in Fahrenheit and c in feet sec The speed of sound in air at a temperature of 0 degrees C and 50 relative humidity is 331 6 m s The speed is proportional to the square root of absolute temperature and it is therefore about 12 m s greater at 20 degrees C The speed is nearly independent of frequency and atmospheric pressure but the resultant sound velocity may be substantially altered by wind velocity Temp 12 C 14 C 16 C 18 C 20C 22 C 24 C 26 C 28 C 330 C Humidit 53 6 F 57 2 C 60 8 C 64 4 F 68 F 71 6 F 75 2 F 78 8 F 82 4 F 86 F 40 339 0 340 2 341 4 342 6 343 9 345 1 346 3 347 6 348 8 350 1 60 339 1 340 4 341 6 342 9 344 1 345 4 346 7 348 0 349 2 350 6 80 339 3 340 5 341 8 343 1 344 4 345 7 347 0 348 3 349 7 351 0 Temp 12 C 14 C 16 C 18C 20C 22 C 24C 26 C 28 C 30C Humidit 53 6 F 57 2 C 60 8 C 64 4 F 68 F 71 6 F 75 2 F 78 8 F 82 4 F 86 F 40 1112 1116 1120 1124 1128 1132 1136 1140 1144 1149 60 1113 1117 1121 1125 1129 1133 1137 1142 1146 1150 80 1113 1117 1121 1126 1130 1134 1138 1143 1147 1152 Comment on HAAS EFFECT or the principal of first arrival Most of us are born with the gift of being able to hear quite easily from where in a circular sphere around us a given sound originates As most of us are born with two ears spaced apart separated by a head the direct sound from any source will arrive at slightly different times to each ear Even in a strong reverberant ambience o2. 3 2 FCC part 15 class B CISPR 22 class B IEC 65 EN 60065 32 F to 122 F 0 C to 50 C 4 F to 140 F 20 C to 60 C Anodized aluminum front Plated cadmium coating steel chassis 19 x 1 75 x 11 6 483 x 44 x 294 mm 11 Ibs 5 kg 14 Ibs 6 4 kg 100 120 220 240 VAC 50 60 Hz selectable lt 30 W 1 year Memory expansion card empty with sockets for 12 x CH01 1 25 sec memory expansion Note Due to continuous development and standardization all specifications are subject to change without notice TC1280 STEREO DIGITAL AUDIO DELAY OWNERS MANUAL Rev 2 1 Software version 2 04 Page 9 of 9
