Ti10 Manual

Controller settings

For acoustic adjustment the functions CUT, HFA, HFC and CPL can be

selected.

CUT circuit

Set to CUT, the Ti10 low frequency level is reduced. The Ti10 is now

configured for use with the Ti-SUB or other d&b active subwoofers.

HFA circuit (T10 PS setup only)

In HFA mode (High Frequency Attenuation), the HF response of the Ti10

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.

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).

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 Ti10 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.
