Connections

Ci7-TOP cabinets are fitted with a single NL4 connector and are driven
using pins 1+/1–.

Installation loudspeakers with the weather resistant option are supplied
with a fixed cable (PG). 

Cable type:

H-07-RN-F 2 x 2.5 mm2/AWG 13 

Standard length: 5.5 m (18 ft) 

Pin equivalents of NL4 connectors and fixed cable option (PG) are listed
in the table below.

Operation with D6 or D12

Select the controller setup C7-TOP.

Within the D12 amplifier this is available in "Dual Channel" and "Mix
TOP/SUB" mode.

Up to a total of two Ci7-TOP loudspeakers can be driven by each D6
or D12 amplifier channel.

In applications with low continuous levels and low ambient temperatures
up to three cabinets can be connected to a D12 channel.

Controller settings

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

CUT

Set to CUT, a high pass filter with a 130 Hz cut off frequency is inserted
in the controller signal path. The Ci7-TOP is now configured for use with
the d&b active subwoofers.

Fig. 2: Frequency response correction of
HFA circuit

In HFA mode (High Frequency Attenuation), the HF response of the
system is rolled off. The HFA circuit 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.

CPL circuit

Fig. 3: Frequency response correction of
CPL circuit

The CPL (Coupling) circuit compensates for coupling effects between the
cabinets when building closely coupled arrays. CPL begins gradually at
1 kHz, with maximum attenuation below 250 Hz, providing a balanced
frequency response when cabinets are used in arrays of two 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).
