Operation manual BSX

Introduction

So far the Big-Subwoofer-eXtender is the biggest TW AUDiO sub to date.

Equipped with two powerful 21“ drivers with a peak performance potential of 10kW per dri-

ver, this speaker is able to reproduce a truly massive bass foundation.

Thanks to the hybrid enclosure principle its efﬁciency is maximised so that the energy is still

perceptible even at a great distance. Primarily the BSX functions as a true sub bass exten-

sion.

Because of its extremely stiff yet lightweight membranes the BSX is able to deliver frequen-

cies of up to 120 Hz clean and true to its impulses. As a full range sub the BSX is directly

combinable with the M, T, C or VERA systems.

Operation manual BSX

1. Safety | Intended use

The BSX loudspeaker was developed for use in professional sound systems. The loudspea-

ker may only be used by trained and qualiﬁed personnel.

WARNING

NOTE

Avoid:

• Feedback

• Distorted signals (clipping) and

• Peaks resulting from switching on devices, plugging in devices or unplugging devices during

operation.

Such signals can lead to loudspeaker overload and ultimately to loudspeaker failure.

Keep away from the immediate vicinity of loudspeakers that are operated at high sound pres-

sure levels. These loudspeaker systems are capable of endangering your health. Sound levels

beginning as low as approximately 90dB SPL can lead to long-term hearing impairment.

When setting up loudspeakers, ensure that they are not exposed to the following ambient

conditions:

• Direct sunlight

• Humidity

• Jolting

• Dust

When working with heavy loads exceeding 20 kg (44 lbs.), use suitable aids (dollies, hoisting

slings, etc.). Multiple persons may be required depending on the situation.

Ensure that the units are in a stable position and are ﬁrmly attached. A falling loudspeaker can

result in serious personal injury and property damage.

When using and assembling TW AUDiO loudspeakers, only use materials speciﬁed by

TW AUDiO. These tasks must be performed by qualiﬁed personnel. Adhere to the applicable

safety regulations.

Loudspeakers generate an electromagnetic ﬁeld. Persons with pacemakers are not permit-

ted to remain in the immediate vicinity of loudspeakers as the electromagnetic ﬁelds can

cause pacemakers to malfunction.

Please adhere to the following safety instructions to avoid risks when operating loudspeakers.

Note the operating modes described in this operating manual. Other uses are not permis-

sible.

Damage caused by improper use is not covered by TWAMBO.

Operation manual BSX

WARNING

NOTE

Check loudspeakers and accessory parts regularly for visible wear. This is essential to ensure

continuing fault-free operation. Worn parts should be replaced immediately. Spare parts are

available from TWAUDiO.

A permanent magnetic ﬁeld is present in the immediate vicinity of loudspeakers. Ensure that

objects which react sensitively to magnetic ﬁelds are not located in the immediate vicinity of

the loudspeaker. In particular, this applies to magnetic storage media, magnetic stripe cards

such as debit cards and CRT displays. A distance of approximately one meter is sufﬁcient to

avoid damage.

Note that TWAMBO does not provide a warranty for damage that can be attributed to this type

of overload and therefore cannot be held liable for any secondary damage.

Ensure that the loudspeaker is not exposed to permanent thermal overloads. Thermal over-

loads may cause a ﬁre and result in serious personal injury and property damage.

2.2 Operation modes

The BSX loudspeaker can be operated in two operation modes. The operation mode is selec-

ted by choosing the preset in the system ampliﬁer.

2.2.1 Full

In full mode, the BSX has a higher upper cutoff frequency. This mode is recommended for

operating the BSX with tops only.

2.2.2 Infra

Infra operating mode is recommended when using the BSX loudspeaker in a system with addi-

tional subwoofers. In this mode, the lower cutoff frequency results in a bass range extension.
