Connections

The Q1 cabinet is fitted with a pair of EP5 connectors. All five pins of

both connectors are wired in parallel. The Q1 uses the pin assignments

1/2. Pins 3/4 and 5 are designated to Q-SUB active subwoofers,

where pin 5 is used for SenseDrive (only available when using a D12

amplifier and 5-wire cabling). Using the male connector as the input,

the female connector allows for direct connection to additional

loudspeakers.

The Q1 can be supplied with NL4 output connectors as an option. Pin

equivalents of EP5 and NL4 connectors are listed in the table below.

Operation with D6 or D12

NOTICE:

Only operate Q1 loudspeakers with a correctly configured d&b

amplifier, otherwise there is a risk of damaging the loudspeaker

components.

The D6 and D12 amplifiers provide two setups (Q1 or Q1 line) for Q1

cabinets (D12 from firmware V2.10). The selection depends on the

curvature of the array. Straight array sections (small splay angles)

extend the acoustical near field of the sources to a considerable extent.

These cabinets need a different tonal balance than cabinets used in

curved array sections. For this reason, both amplifier configurations are

used within typical Q1 arrays.

Within the D12 amplifier the setups are available in "Dual Channel"

and "Mix TOP/SUB" mode.

Up to a total of two Q1 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.

Select the respective controller setup Q1 or Q1 Line.

"Q1" setup

The Q1 setup (standard configuration) is used for Q1 loudspeakers in

small arrays of up to 4 cabinets and in curved sections of larger arrays.

With more than two consecutive splay settings of 0°, 1° or 2° the "Line"

configuration should be used for the respective cabinets.

"Q1 Line" setup

The "Line" configuration is used for groups of four or more Q1

loudspeakers which are coupled to form a straight long throw array

section where the splay angles to adjacent cabinets are 0°, 1° or 2°.

Compared to the standard configuration the mid/-high range is

reduced to compensate for the extended near field.

The transition from "Q1 Line" to "Q1" configuration within the array is

made according to the splay progression but may allow for certain

deviations due to the paired wiring of the cabinets.
