Safety precautions
Information regarding use of loudspeakers
WARNING!
Never stand in the immediate vicinity of loudspeakers driven at a high
level. Professional loudspeaker systems are capable of causing a sound
pressure level detrimental to human health. Seemingly non-critical
sound levels (from approx. 95 dB SPL) can cause hearing damage if
people are exposed to it over a long period.
In order to prevent accidents when deploying loudspeakers on the
ground or when flown, please take note of the following:
When setting up the loudspeakers or loudspeaker stands, make sure
they are standing on a firm surface. If you place several systems on top
of one another, use straps to secure them against movement.
Only use accessories which have been tested and approved by d&b for
assembly and mobile deployment. Pay attention to the correct
application and maximum load capacity of the accessories as detailed in
our specific “Mounting instructions” or in our "Flying system and Rigging
manuals".
Ensure that all additional hardware, fixings and fasteners used for
installation or mobile deployment are of an appropriate size and load
safety factor. Pay attention to the manufacturers' instructions and to the
relevant safety guidelines.
Regularly check the loudspeaker housings and accessories for visible
signs of wear and tear, and replace them when necessary.
Regularly check all load bearing bolts in the mounting devices.
CAUTION!
T10 Manual
Loudspeakers produce a static magnetic field even if they are not
connected or are not in use. Therefore make sure when erecting and
transporting loudspeakers that they are nowhere near equipment and
objects which may be impaired or damaged by an external magnetic
field. Generally speaking, a distance of 0.5 m (1.5 ft) from magnetic
data carriers (floppy disks, audio and video tapes, bank cards, etc.) is
sufficient; a distance of more than 1 m (3 ft) may be necessary with
computer and video monitors.

T10
The T10 is a very compact loudspeaker system which can be used both
as a line array and as a high directivity point source speaker. For these
applications the T10 cabinet provides two different dispersion
characteristics which can be swapped over without any tools.
Fig. 1: T10 loudspeaker
The core of the design is a unique combination of a rotatable
waveguide with horn and an acoustic lens. The horn natively provides a
vertical line source with 90° horizontal dispersion. The lens is part of the
front grill and widens the HF dispersion in line array mode to 105°.
When used upright as a point source, the lens curves the wavefront of
the line source providing a 90° x 35° dispersion pattern.
The T10 is a two way design employing dual 6.5” drivers, a 1.4” exit
compression driver and a passive crossover network. The low drivers
are positioned in a dipolar arrangement providing an exceptional
dispersion control towards low frequencies. Its frequency response
extends from 68 Hz to above 18 kHz.
Fig. 2: T10 Horn and lens
in line source setup
The T10 enclosure is constructed from polyurethane integral hard foam
with an impact and weather resistant black paint finish. The cabinet
shape allows the system to be set up as a single unit in upright
orientation or as a line array in user defined vertical configurations. The
front of the loudspeaker cabinet is protected by a rigid metal grill in
front of an acoustically transparent foam.
NOTICE: Only operate T10 loudspeakers with a correctly
configured d&b amplifier, otherwise there is a risk of
damaging the loudspeaker components.
T-Series rigging components and arrays
Fig. 3: T10 Horn and lens
in point source setup
For point source applications the T10 is fitted with six threaded inserts to
connect to different rigging accessories like Z5371 T Flying bracket,
Z5372 T Horizontal bracket, Z5354 E8/E12 Flying adapter or
Z5020/25 Flying adapter 02/03.
When applied as a line array, cabinets are mechanically connected
using the rigging strands on both sides of the cabinet front and a
central strand at the rear of the cabinet. All necessary rigging
components are mounted to the cabinet and are folded or slide out
when needed. Splay angles between adjacent cabinets can be set in the
range from 0° to 15°.
A detailed description of the T-Series rigging components is given in the
T-Series Rigging manual which is provided with the Z5370 T Flying
frame.
T10 line arrays of up to 3 cabinets can be supported with the
Z5373 T Cluster bracket which allows an easy aiming of the array
either flown or mounted on a high-stand.
A detailed description of planning and designing T-Series arrays is
given in the technical information "TI 385 J, Q and T-Series system
design, d&b ArrayCalc" which is also provided with the T Flying frame.
The d&b ArrayCalc array calculator can be downloaded from the d&b
website at www.dbaudio.com.

The T10 cabinet is fitted with a pair of EP5 connectors. All five pins of
both connectors are wired in parallel. The T10 uses the pin assignments
1/2. Pins 3/4 and 5 are designated to active subwoofers, where pin 5 is
used for SenseDrive (only available when using a D12 amplifier and 5wire cabling). Using the male connector as the input, the female
connector allows for direct connection to additional loudspeakers.
The T10 can be supplied with NL4 connectors as an option.
Pin equivalents of EP5 and NL4 connectors are listed in the table below.

Operation with D6 or D12
Select the controller setup T10.
The D6 and D12 amplifiers provide three configurations for T10
loudspeakers.
Within the D12 amplifier they are available in "Dual Channel" and "Mix
TOP/SUB" mode.
Up to a total of four T10 loudspeakers can be driven by each channel
of the D6 or D12 amplifiers.
"T10 Arc" and "T10 Line" setups
These setups are selected when T10 loudspeakers are used as line
sources. The selection depends on the curvature of the array. Both
setups may be used within one array.
The "Arc" setup is used for T10 loudspeakers when used in curved
array sections.
The "Line" setup is used for long throw array sections with three or
more consecutive splay settings of 0°, 1°or 2°. Compared to the "Arc"
setup, the upper mid range is reduced to compensate for the extended
near field.
The transition from "Line" to "Arc" configuration within the array is
made according to the splay progression but may allow for certain
deviations due to the wiring of the cabinets in groups of up to four.
"T10 PS" setup
This setup has to be selected when T10 loudspeakers are configured as
a point source or when used as single cabinets with horn in line array
configuration (e.g. front fill or ceiling mounted).

Controller settings
For acoustic adjustment the functions CUT, HFA, HFC and CPL can be
selected.
CUT circuit
Set to CUT, the T10 low frequency level is reduced. The T10 is now
configured for use with the T-SUB or other d&b active subwoofers.
HFA circuit (T10 PS setup only)
In HFA mode (High Frequency Attenuation), the HF response of the T10
system is rolled off. HFA provides a natural, balanced frequency
response when a unit is placed close to listeners in near field or delay
use.

High Frequency Attenuation begins gradually at 1 kHz, dropping by
approximately 3 dB at 10 kHz. This roll-off mimics the decline in
frequency response experienced when listening to a system from a
distance in a typically reverberant room or auditorium.

HFA circuit
HFC circuit (T10 Arc/Line setups only)
Selecting the HFC (High Frequency Compensation) circuit compensates
for loss of high frequency energy due to absorption in air when
loudspeakers are used to cover far field listening positions.
The HFC circuit has two settings (HF1, HF2) for different distance ranges
the cabinets have to cover. The settings should be used selectively, only
for those cabinets covering the respective distances, HF1 for distances
larger than 25 m (80 ft) and HF2 for distances larger than 50 m
(160 ft).
Fig. 6: Frequency response correction of
HFC circuit
The compensation is adjusted for a typical relative humidity of 40 %.
With lower humidity the absorption by air increases therefore the
distances where the respective HFC setting provides a correct
equalization are shorter than indicated above.
Using the HFC function provides the correct sound balance between
close and remote audience areas, whilst all amplifiers driving the array
can be fed with the same signal.
CPL circuit
The CPL (Coupling) circuit compensates for coupling effects between the
cabinets; these effects increase as the length of the line array is
extended. CPL begins gradually at 1 kHz, with the maximum attenuation
below 400 Hz, providing a balanced frequency response when T10
cabinets are used in arrays of four or more. The function of the CPL
circuit is shown in the diagram opposite and can be set in dB
attenuation values between –9 and 0, or a positive CPL value which
creates an adjustable low frequency boost around 65 Hz (0 to +5 dB).
Note: Make sure that all cabinets within the line array are operated
with the same CPL setting.

Altering the HF dispersion
Swapping between point and line source setups is performed by simply
rotating the horn by 90°. The horn is easily accessible from outside of
the cabinet and can be rotated without any tools or removal of the
front grill.
This is achieved through apertures on the cabinet sides by a mechanism
that provides detents at both the line and point source positions.
