Ti10P Point source

T10 PS

For applicable d&b amplifiers, the controller setups are available

in Dual Channel and/or Mix TOP/SUB mode. For combinations

with active subwoofers fed by a single 4-wire cable Mix TOP/SUB

mode must be selected.

"T10 Arc" and "T10 Line" setups

These setups are selected when Ti10L 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 Ti10L 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 Ti10L 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).

2.3.1 Controller settings

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

be selected.

CUT mode

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

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

HFA mode (Ti10 PS setup only)

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

system is rolled off. HFA provides a natural, balanced frequency

response when a cabinet 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.
