General Safety Instructions:

Professional loudspeakers can produce harmful sound pressure levels. SPLs above 95 dB can permanently damage your hearing. Observe the relevant guidelines regarding working safety and health protection.

To avoid physical and personal damages due to loudspeakers dropping or tumbling over, please make sure that the speakers stand safely on a ﬁrm ground.

Vertically stacked loudspeakers must be secured sufﬁciently with tension belts against unintentional movement.

Check all cabinets and accessories regularly for wear, especially the ﬂying rails and the tripod ﬂange. Replace them if necessary. Make sure that during operation on spacer tubes, no persons will stand close to the loudspeakers.

Use only accessory parts speciﬁed by ProAudio Technology or original accessory parts from ProAudio Technology.

Loudspeakers always produce a magnetic ﬁeld. Make sure that during transport, setup and disassembly and also during operation of the loudspeakers no objects (such as laptops, harddisk drives, credit cards and the likes) get close to the speakers which could become damaged by the magnetic ﬁeld. People who have a pacemaker must keep a safety clearance.

The minimum recommended safety clearance is 1 m.

Do not set up the loudspeakers in places where they are permanently exposed to moisture, dust, dirt or direct sunlight.

Care:

Wipe the surface of loudspeakers only with a damp cloth and pure water.

In case of heavy pollution, repeat the above procedure several times if necessary.

Do not use any chemical additives or aggressive detergents, as these may harm and damage the surfaces.

Note:

Only one 4-pole cable is required to connect 2-channel combinations of several SW18 and tops.

Only one 4-pole cable is required to connect 2-channel sub arrays like e.g. 2 x 4 SW18.

Description:

The SW18 is a compact 18“ bassreﬂex subwoofer for sound systems with an active frequency crossover.

It can be used for all kinds of sound reinforcement, from standalone applications to massive cardioid subwoofer arrays. Large, symmetrically positioned bass reﬂex ports allow a controlled and loss-free low-end reproduction.

Operation is to be made (exclusively) using the ProAudio Technology system ampliﬁers. Two different setups – omnidirectional (front) and cardioid (front and rear) – enable a practice-oriented usage. Alternatively you can also use ampliﬁers of the Hoellstern DELTA series with built-in DSP. If you have any questions regarding this issue, please contact ProAudio Technology.

Cabinet:

The cabinet is made of 15 mm birch multiply wood and coated with a robust two-component texture paint ﬁnish. It is ﬁtted with four recessed handles, an M20 steel ﬂange, two front lid attachments and four stacking feet with matching recesses on the opposite side. Behind the front grille is a layer of black acoustic foam.

Connection:

The connections are made on the rear side through two Neutrik NL4 SpeakON sockets wired in parallel.

Pin pair 1 may be used to hook up tops (slave-through option). Pin pair 2 is connected to the subwoofer chassis.

There are two additional SpeakON connectors on the front side.

Pin pair 1 of the front sockets is connected to the subwoofer chassis. These connectors have been provided for optionally tapping off a second channel with sub arrays or cardioid sub arrays (CSA operation mode). The CSA mode will be explained in detail on the following pages of this manual.

Combinations of SW18 and tops, which are supplied via a 4-pole speaker cable, must only be connected at the rear SpeakON sockets of the SW18 subwoofers!

Never use the SpeakON sockets on the front side.

Operation on System Ampliﬁers:

The ampliﬁer conﬁguration software will display help texts for the individual loudspeakers. Select a setup which contains the name “SW18“. The “CSA“ (Cardioid Sub Array) option must be used for cardioid applications.

On the DELTA8.4-DSP system ampliﬁer up to two SW18 can be driven per channel.

On the DELTA14.4-DSP system ampliﬁer a maximum of four SW18 can be driven per channel.

Details will be shown by the software upon entering the number of SW18 subwoofers per channel.

Note:

Use the SW18 subwoofer only on system ampliﬁers with the available setups. Otherwise there may be a risk of damage and inadequate performance.
