1. Safety precautions

1.1. Information regarding the use of loudspeakers Potential risk of personal injury

Never stand in the immediate vicinity of loudspeakers driven at a high level. Professional loudspeaker systems are capable of causing a sound pressure level detrimental to human health. Seemingly non-critical sound levels (from approx. 95 dB SPL) can cause hearing damage if people are exposed to it over a long period.

In order to prevent accidents when deploying loudspeakers on the ground or when flown, please take note of the following:

– When setting up the loudspeakers or loudspeaker stands,

make sure they are standing on a firm surface. If you place several systems on top of one another, use straps to secure them against movement.

– Only use accessories which have been tested and approved

by d&b for assembly and mobile deployment. Pay attention to the correct application and maximum load capacity of the accessories as detailed in our specific "Mounting instructions" or in our "Flying system and Rigging manuals".

– Ensure that all additional hardware, fixings and fasteners used

for installation or mobile deployment are of an appropriate size and load safety factor. Pay attention to the manufacturers' instructions and to the relevant safety guidelines.

– Regularly check the loudspeaker housings and accessories for

visible signs of wear and tear, and replace them when necessary.

– Regularly check all load bearing bolts in the mounting devices.

Potential risk of material damage

Loudspeakers produce a static magnetic field even if they are not connected or are not in use. Therefore make sure when erecting and transporting loudspeakers that they are nowhere near equipment and objects which may be impaired or damaged by an external magnetic field. Generally speaking, a distance of 0.5 m (1.5 ft) from magnetic data carriers (floppy disks, audio and video tapes, bank cards, etc.) is sufficient; a distance of more than 1 m (3 ft) may be necessary with computer and video monitors.

2. 18S-SUB/18A-SUB loudspeaker

2.1. Product description

The 18S-SUB and 18A-SUB are compact high performance subwoofers for use with d&b xS-Series and xA-Series loudspeakers. The cabinets house a long excursion 18” neodymium driver in a bass-reflex design.

The 18A-SUB incorporates the same acoustic components as the 18S-SUB, however, the cabinet is equipped with an integrated rigging system for the design of vertical arrays. The 18A-SUB can be combined with 10A and 10AL loudspeakers.

The frequency response extends from 37 Hz to 140/100 Hz.

The enclosures are constructed from marine plywood with an impact resistant black paint finish. The fronts of the cabinets are protected by a rigid metal grill backed by an acoustically transparent foam. The 18S-SUB is equipped with four rubber feet to prevent cabinet movement and protect the bottom panel against scratching.

The cabinets are Ball Impact Resistant according to DIN 18032-3.

Fig. 1: 18S-SUB/18A-SUB loudspeaker Rigging examples:

18S-SUB ceiling mounted with Z5410 Horizontal bracket 18S/27S. 10AL/18A-SUB array.

18S-SUB rigging components

The 18S-SUB side panels are each equipped with a pair of M10 threads to accept the Z5410 Horizontal bracket 18S/27S. The threaded inserts are covered by dummy caps in cabinet color. The caps must be removed before mounting any accessories.

18A-SUB rigging components

18A-SUB cabinets are connected to form a vertical array each using the Z5418 Connector plates xA-SUB. Up to four 18A-SUB cabinets can be connected. When integrated at the top of a 10A or 10AL array, up to two 18A-SUB cabinets can be combined with up to six 10A/10AL cabinets.

Vertical arrays are supported using the Z5414 Flying bar xA and the Z5413 Flying bar connector plates xA. For approved configurations as well as safety and mounting instructions, refer to the respective rigging manual.

Cabinet options

The weather resistant version (WR) is suitable for outdoor use (IP34, vertical aiming up to 0°). The cabinets have an impact and weather protected black PCP (Polyurea Cabinet Protection) finish.

2.2. Connections

The cabinets are fitted with a pair of NL4 connectors and a two pole screw terminal block (ST). All four pins of both NL4 connectors are wired in parallel. The cabinets use the pin assignments 2+/2–. Pins 1+/1– are designated to full range cabinets.

Cabinets with the weather resistant option (WR) are equipped with a fixed input cable (PG type, H07-RN-F, 2 x 2.5 mm2 (AWG 13), standard length 5.5 m (18 ft).

Pin equivalents of the applicable connector options are listed in the table below.

Fixed cable connection

The 18S-SUB and 18A-SUB loudspeakers are each supplied with a cover plate [1] and a rubber grommet feed through [2]. For indoor operation, these items can be used to hide the connector panel, if required. For unprotected outdoor operation, the connector panel must be covered, i.e. both items must be used to achieve an IP degree of protection of IP34.

To install the fixed cable connection, proceed as follows:

Tools required: Philips screw driver (#PH2).

1. Prepare the rubber grommet and the connection cable.

2. Remove the knockout opening in the cover plate and attach the rubber grommet correspondingly.

3. Insert the connection cable through the rubber grommet and connect the cable wires to the screw terminal. Þ Observe the correct polarity!

4. Undo the four screws of the connector panel.

5. Push the cover plate towards the connector panel until it fits into place.

6. Finally fix the cover plate together with the connector panel using the four screws.

NL4 connection with cover plate

The two NL4 connector sockets of the cabinet's connector panel are located in a recess to allow the use of the cover plate [1] together with NL4 cable connectors, as shown in the graphic opposite.

Note: Neutrik NL4FC type connectors must be used for this option.

The cover plate is equipped with two knockout openings to allow daisy chaining of the loudspeaker.

To use the NL4 connection, proceed in the same manner as described above in the section entitled Þ "Fixed cable connection" on page 6.

2.3. Operation

NOTICE!

Only operate d&b loudspeakers with a correctly configured d&b amplifier, otherwise there is a risk of damaging the loudspeaker components.

Operation with D6 or D12

Select the controller setup 18S-SUB for 18S or 18A subwoofers.

Within the D12 amplifier it is available in "Dual Channel" and "Mix TOP/SUB" mode. For combinations with full range systems fed by a single 4-wire cable "Mix TOP/SUB" mode must be selected.

Up to a total of two 18S-SUB or 18A-SUB loudspeakers can be driven by each channel of the D6 or D12 amplifiers.

2.3.1. Controller settings

For acoustic adjustment the 100 Hz function can be selected.

100 Hz circuit

If the 100 Hz circuit is selected, the upper operating frequency of the system is reduced from 140 Hz to 100 Hz.
