Ci45/Ci60/Ci90 Manual

Connections

Since November 2004 the Ci45/Ci60/Ci90 cabinets are fitted with two

NL4 connectors. All pins of both connectors are wired in parallel using

the pin assignments 1+/1–. Using one connector as the input, the

second connector allows for direct connection to additional

loudspeakers.

Installation loudspeakers with the weather resistant option are supplied

with a fixed cable (PG).

Cable type:

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 Ci45, Ci60 or Ci90.

Within the D12 amplifier these are available in "Dual Channel" and

"Mix TOP/SUB" mode.

Up to a total of two Ci45/Ci60/Ci90 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 circuit

Set to CUT, the Ci45/Ci60/Ci90 low frequency level is reduced. The

loudspeaker is now configured for use with the Ci-SUB, Q-SUB or d&b

C-Series subwoofers.

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.
