TBV BERLIN SERIES
Subwoofer Time Alignment
TURBOSOUND TBV LAKE DSP settings include user
1)
adjustable delays on TBV123 and TBV118L channels.
For example: If the fronts of the TBV123 & TBV118L
are aligned then in both pre-sets the delay should
be set to the default which is 0ms.
However in the real world it is not always possible
to have your fl own array and your ground stacked
bass aligned in the vertical plane.
1) In the picture to the right the TBV118L bass is
'forward' of the TBV123 fl own array. So the TBV118L
needs to be delayed .
2)
2) In the picture to the right the TBV123 fl own array
is now 'forward' of the TBV118L ground stacked
bass . So the TBV123 array needs to be delayed.
So how do you fi nd the correct delay time to align
the fl own array to the ground stacked bass?
Some basic knowledge of delay units can get you
an acceptable result by measuring the distance
between the fronts of the fl own array and the front
of the ground stacked array. Remember within
LAKE software you can choose the delay unit;
ms, m or feet.
1 ms (milliseconds) = 0.343 m (meters) =
1.125 ft (feet)
Further fi ne tuning can be done by using one of the
many industry standard measurement software
systems, reference microphones and sound-cards.
LAKE software off ers integration to many of these
software systems, further information can be
