Frequently Asked Questions - IS3TTRF DB Technologies

How to install the IS3TTRF speaker?

Use the supplied wall bracket to mount the speaker to the wall, vertically or horizontally. Adjust the desired tilt. The installation must be carried out by a qualified technician.

What type of cable to use?

Use cables of appropriate gauge for the distance. For Euroblock connections, observe polarity. Avoid placing cables near sources of electromagnetic interference.

How to choose 8 Ω or 70/100 V mode?

Use a flathead screwdriver to turn the rotary switch on the back. Select the appropriate power setting (e.g., 2.5 W, 5 W, etc.) according to your amplifier voltage.

What to do if the speaker produces no sound?

Check the connection to the amplifier, the power selector setting, the condition of the cables, and that the audio source is powered on and delivering a signal.

Is the speaker waterproof?

Yes, the IP55 protection rating ensures protection against dust and water jets. Ensure the PG7 cable gland is properly secured to maintain the seal.

What accessories are included?

The package contains the IS3TTRF speaker, a wall bracket, an IP55 panel, a PG7 cable gland, a quick guide, and warranty documents.

Can this speaker be used with a standard amplifier?

Yes, in 8 Ω mode, it connects directly to a standard amplifier. In 70/100 V mode, it requires a compatible constant voltage amplifier.

How to clean the speaker?

Use a soft dry cloth. Do not use solvents, alcohol, or abrasive products that could damage the surface.

What is the difference between the IS3T, IS5T, IS6T models?

The woofer size differs: 3.5 inches for IS3T, 5.25 inches for IS5T, 6.5 inches for IS6T. The power, frequency response, and max SPL increase with size.

Can I control the speaker remotely?

Yes, if connected to a DB Technologies IA504 amplifier, you can use the Aurora Net software for remote control and download optimized presets.

GENERAL INSTRUCTIONS FOR CONNECTING SPEAKERS 20

Thanks for purchasing a product that was designed and developed in Italy by dBTechnologies! This series of installation speakers embodies years of experience and innovation in the field of sound reproduction, with the use of cutting edge solutions in the fields of acoustics and materials research.

INTRODUCTORY OVERVIEW

IS-TRF is the new series of two-way passive speakers dedicated to installation, designed with the specific needs of installers in mind. The three models in the IS3T-TRF, IS5T-TRF, IS6T-TRF series (with 3.5", 5.25" and 6.5" woofers respectively) are intended to reproduce high quality background music in fixed, indoor and outdoor installations; their elegant and discreet look makes them suitable for any commercial and institutional context. Connection is quick and easy thanks to the Eurobock (Phoenix) connectors. The main features are:

• ergonomic, compact and versatile design
• supplied with a bracket for quick and easy wall mounting
• wide acoustic coverage
  adjustable tilt angle
• designed for constant impedance (8 Ohm) or voltage (70V or 100V) installations

USER INFORMATION

To use your IS TRF speaker in the best way, we recommend that you:

• read the Quick Start manual included in the package and all of this User Manual, and keep them throughout the entire life of the product.
• register the product in the "SUPPORT" section of the http://www.dbtechnologies.com website.
• keep your proof of purchase and the WARRANTY (User manual "section 2").

MECHANICAL AND ACOUSTIC FEATURES

DIMENSIONS AND WEIGHT

ACOUSTIC COVERAGE

The acoustic coverage varies according to the speaker model, as follows:

IS3T-TRF 110^× 100^ (HxV)
IS5T-TRF 85^80^ (HxV)
IS6T-TRF 80^ × 75^ (HxV)

MECHANICAL FEATURES

Speaker ergonomics and quick installation are ensured by:

4 rear holes for IP55 panel fastening
- 4 rear holes for fastening with the included wall bracket

PROTECTION AGAINST SOLID OBJECTS AND LIQUIDS (IP RATING)

The speaker is protected against the ingress of solid objects and liquids with a rating of IP55 as defined by IEC 60529.

Only use cables with the following diameters:

with PG7 cable glands diameter from 3.5 to 6mm

Secure the cable gland properly using the plastic tightening nut.

CAUTION!

Failure to comply with these installation prescriptions could adversely affect the declared protection ratings.

2. CONNECTIONS

The audio input and link to another speaker are connected via a Euroblock (Phoenix) connection; the connector is protected under a metal panel with a PG7 cable gland that is easily removed by unscrewing the four screws securing it to the cabinet. Connect the audio source (e.g., from an amplifier or another speaker) to the INPUT terminal, respecting the polarity markings next to the connectors. The audio signal can be linked to another speaker in a similar way: connect the LINK output of the speaker to the INPUT terminal of the next speaker respecting the polarity.

3. INSTALLATION AND CONFIGURATION

PACKAGE CONTENTS

On opening the IS-TRF speaker package, check that no items are missing. The package contains:

IS-TRF speaker
- wall-mounting bracket
IP55 panel
PG7 cable gland
- quick start manual and warranty documentation

CAUTION!

Only expert personnel may use the product and its accessories! To prevent hazards to people, animals and/or objects, make sure that the installation is stable and secure. Comply with the safety regulations and laws in force in the country in which you use the product. For safe use, periodically check that all parts are in good working condition before use. Only authorised personnel may carry out design, calculations, installation, testing and maintenance of professional flown or stacked audio systems. dBTechnologies shall not be liable for improper installation without adequate safety measures.

This section illustrates some installation examples. Also consult the instructions for the accessories, as well as any prescriptions reported on the product labels.

WALL MOUNTING

The speaker can be wall mounted vertically or horizontally using the included bracket. Fasten the wall bracket using suitable screws and bolts (not supplied). Adjust the mechanics of the bracket to achieve the desired rotation/tilt.

CAUTION!

• Only use brackets and accessories approved by the manufacturer to install the speaker in flown configurations

IS-TRF Cod. 420120453 REV. 1.1

GENERAL INSTRUCTIONS FOR CONNECTING SPEAKERS

Consider the following instructions when making the connections:

• Use cables of suitable section. The greater the distance between the amplifier and speaker, the greater the cable section required. This prevents signal losses along the line.
• To prevent inductive phenomena from causing buzzing or noise, and compromising proper system operation, do not place the connection cables in the same duct as or near devices that produce strong magnetic fields (e.g. power transformers), power conductors and speaker input lines. Moreover, use cables with twisted conductors to minimise inductive effects due to coupling with electric fields.
• Connect the speakers "in phase" to ensure correct sound reproduction. That is, the positive and negative polarity of the amplifier must correspond to the positive (70-100V) and negative (COM) polarity of the speaker input.
• To simplify the connection, you can use bipolar cables with marking (e.g. different colours) to distinguish the polarity.

The speaker input voltage must match the voltage selected on the amplifier, and the sum of the powers of all the speakers connected to the audio line must not exceed the rated amplifier power.

70-100V

LOW IMPEDANCE CONFIGURATION

The total load impedance of all the speakers must be no lower than the rated amplifier impedance, and the length of the connection cables must be minimised.

IS-TRF

Cod. 420120453 REV. 1.1

The configuration type is selected using the rotary selector at the bottom rear of the speaker. Use a flat-blade screwdriver to make the choice. The table below shows the configurations that can be selected for each speaker.

REMOTE CONTROL

When connected to dBTechnologies IA504 amplifiers, IS-TRF speakers can be controlled remotely via AURORA Net software. This can load presets made by dBTechnologies specifically for this series to optimise sound performance as much as possible. You can further refine the output sound by adjusting the equalisation and limiter. The presets can be downloaded free of charge from the www.dbtechnologies.com website.

4. TROUBLESHOOTING

The speaker does not produce any sound:

1. Check that the speaker and amplifier are connected correctly.
2. Check that the speaker power selector is set correctly.
3. Check that the cables used are not damaged.
4. Check that the audio source is powered on and clearly shows an output signal.
