TW Audio B15 Bedienungsanleitung

B15 Operating Manual

Introduction

Thank you for choosing a high quality product "MADE IN GERMANY" from TW AUDiO.

Our B15 loudspeaker is a true multi-talent, especially with the optional passive cross-

over PWB15. The 1× 15" fitted bass reflex system is suitable for the switchable bi-amp

mode or as a passive bass extension for our M and C series loudspeakers.

The passive crossover has a satellite output with a switchable high-pass filter. This en-

ables the B15 loudspeaker to be passively used without additional system controllers to-

gether with various 8 ohm loudspeakers with one standard amplifier.

B15 Operating Manual

1. Safety | Intended use

Please adhere to the following safety instructions to avoid risks when operating the loud-

speakers.

The B15 loudspeaker was developed for use in professional sound systems. The loud-

speaker may only be used by trained and qualified personnel.

Note the operation modes described in this operating manual.

Other uses are not permissible.

TW AUDiO GmbH shall not be held liable for any damage that ensues from unintended

use.

WARNING

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

mitted to remain in the immediate vicinity of loudspeakers as the electromagnetic fields

can cause pacemakers to malfunction.

WARNING

When working with heavy loads over 20 kg [44,09 lbs], use suitable aids (dollies, hoist-

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

Ensure that the units are in a stable position and are firmly attached. A falling loud-

speaker 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 appli-

cable safety regulations.

NOTE

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

conditions:

• Direct sunlight

• Moisture

• Jolting

•Dust

WARNING

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

pressure levels. These loudspeaker systems are capable of endangering your health.

Sound levels beginning as low as approx. 90 dB SPL can lead to long-term hearing im-

pairment.

NOTE

Avoid:

• Feedback

• Distorted signals (clipping)

• Peaks that result when devices are switched on or hot plugged and unplugged.

These signals can lead to loudspeaker overload..

B15 Operating Manual

Note that TW AUDiO 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.

WARNING

Ensure that the loudspeaker is not exposed to permanent thermal overloads. This may

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

NOTE

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 data carriers, EC cards

and CRT displays. A distance of approx. one meter is sufficient to avoid damage.

NOTE

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

ensure fault-free operation on a permanent basis. Replace worn parts promptly. Spare

parts can be obtained from TW AUDiO.

B15 Operating Manual

The B15 loudspeaker comes in two different variants. These variants are the

B15A (ACTIVE model) and B15P (PASSIVE model).

2.2.1. B15A/B15P models

The standard model of the B15 loudspeaker is the B15A variant, which can only be op-

erated in the "ACTIVE" operating mode. It is supplied with a standard connection panel.

The separation occurs in the DSP of the amplifier.

The B15P model can also be operated in the "PASSIVE 1" and "PASSIVE 2" modes.

This permits the connection of an additional loudspeaker on the high-pass output or the

link output when operating with only one amplifier channel. The installed passive cross-

over (pos. 8 “Figure 2.1 - Overview” on page 3) has two selector switches, which are de-

scribed in the following section.

The top selector switch is used to activate the high-pass output. The bottom selector

switch is used to activate the passive crossover and changes the pin assignment of the

connection sockets.

In operation mode 1 "ACTIVE", the internal passive crossover is switched out of the sig-

nal path, and the separation of the loudspeakers must take place in the DSP of the am-

plifier. The pin connection of the B15 loudspeaker is switched to pin 2 +/-.

B15 Operating Manual

In operation mode 3 "PASSIVE 2", the B15 loudspeaker is operated with an

M8 loudspeaker on the "high-pass output". The separation of the two loudspeakers is

performed via the internal passive crossover. The pin connection of the

B15 loudspeaker is switched to pin 1 +/-.
