ARRAY SIZE COMPENSATION
The array size compensation overlay provides a convenient control to
compensate for the LF versus MH tonal balance oset that occurs for larger
arrays. Lowering the MESA lter compensates for low-mid buildup in the
100-300 Hz region and the Low Shelf lter can be used to achieve the overall
desired LF versus MH tonal balance characteristic.
BAND LEVEL EQ (BLEQ)
The Band Level EQ overlay can be used for circuit level gain shading and tapering
adjustments. Band level shading adjustment is recommended as opposed to LF,
MF, HF output channel gain shading in order to preserve proper summation and
power response between adjacent bands.
Note: It is not recommended to mix ST, LT and XLT modes within the same array
(for example, ST mode on lower circuits, LT mode on middle circuits and XLT
on upper circuits of the array). For more precise control of SPL distribution and
frequency response throughout the intended array coverage region, all array
circuits should be operated in ST, LT or XLT mode and circuit-level gain shading
and tapering adjustments implemented using the Band Level EQ Overlay.
For short-to-medium throw applications, use ST presets for all array circuits and
apply HF shelving boost to upper circuits.
For medium-to-long throw applications, use LT or XLT mode for all array circuits
and apply HF shelving reduction to lower circuits.
Turbosound TLX Lake DSP settings include
user adjustable delays on TLX43, TLX84,
TLX212L and TLX215L channels.
For example: If the fronts of the TLX43 &
TLX212L 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 own array and your
ground stacked bass aligned in the vertical
plane.
1) In the picture to the right the TLX212L bass
is ‘forward’ of the TLX43 own array. So the
TLX212L needs to be delayed.

2) In the picture to the right the TLX43 own
array is now ‘forward’ of the TLX212L ground
stacked bass . So the TLX43 array needs to be
delayed.
So how do you nd the correct delay time to
align the 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 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 ne tuning can be done by using one
of the many industry standard measurement
software systems, reference microphones and
sound-cards. Lake software oers integration
to many of these software systems,
