GEO T TANGENT ARRAY SYSTEM CHECK LIST Page 45/63
5.4 Are the speakers properly connected and angled ?
Attach the first 6 array modules to the bumper.
Before flying, verify that all channels of all modules are functioning properly.
Make sure that each module is producing the proper front/rear summation: when listening from
behind the array, switch the front drivers in and out. You should hear a reduction in the LF range
when the both front and rear drivers are on as compared to when the rear drivers only are on.
When listening from the front, you should hear a strong increase in the LF range when
connecting the rear drivers.
To check that all front elements have the proper amplitude and phase, you should listen to the six
box cluster at a close distance (<1 meter). You should be able to move from the top to the bottom
of the cluster without hearing any change in the tonal balance.
Verify that the angle settings are the same on both sides of each module.
Raise the bumper, attach the next 6 modules and repeat the above checks.
Make sure that these 6 modules sum properly with the modules above them.
When all the modules are flown, check that the aiming angles are the same left and right.
Verify that the CD18 is functioning properly: when listening from behind the subs, summing the
front and rear sub drivers lowers the level in comparison with rear driver only.
Make sure that multiple CD18s are summing properly: 6 dB gain per doubling of quantity.
5.5 Final Pre-Sound Check Check
Play a CD track mono left, and then right : both sides must sound strictly identical. When listening in the
center between two Vertical Tangent Arrays, everything from LF to HF should be located to the
“phantom center” position. If not, repeat the above check sequence to identify the source of the
problem.
