in a residential installation. This equipment generates, uses and can radiate radio frequency energy and, if not

installed and used in accordance with the instructions, may cause harmful interference to radio communications.

However, there is no guarantee that interference will not occur in a particular installation. If this equipment does

cause harmful interference to radio or television reception, which can be determined by turning the equipment

off and on, the user is encouraged to try to correct the interference by one or more of the following measures:

—Reorient or relocate the receiving antenna.

—Increase the separation between the equipment and receiver.

—Connect the equipment into an outlet on a circuit different from that to which the receiver is connected.

—Consult the dealer or an experienced radio/TV technician for help.

Make sure that the loudspeaker is securely installed in a stable position to avoid any injuries or damages to

persons or properties. For safety reasons di not place one loudspeaker on top of another without proper fastening

systems. Before hanging the loudspeaker check all the components for damages, deformations, missing or

damaged parts that may compromise safety during installation. If you use the loudspeakers outdoor avoid spots

exposed to bad weather conditions.

Contact dBTechnologies for accessories to be used with the speakers. dBTechnologies will not accept any

FEATURES OF THE AMPLIFIER AND CONTROL SECTIONS

Class D digital custom amplier, SMPS, is at the heart

of SUB 615 and SUB 618.

The system is silent and is controlled by a dedicated

DSP that manages the different parameters.

The sound amplication power is 600 W RMS.

The amplier panel is made up of:

WARNING!

• Input, Output and Control Section

• Power Supply Unit Section

• Never attempt to disassemble the

amplier in any way.

• In case of overheating, the audio

volume is gradually reduced until

module thermal stabilization. The

level is autotically restored when

the correct operating temperature

is reached.

• In the event of a malfunction,

immediately cut power supply

off, by disconnecting the module

from the mains, and contact an

authorised repair centre.

POWER SUPPLY UNIT SECTION INPUT, OUTPUT AND CONTROL SECTION

• Never remove the front grille

protecting the product. To

prevent electric shock, in case of

protection grille accidental damage

or replacement (to be carried

out at the after-sales service),

immediately disconnect power

supply. Never connect mains power

supply when the grille is removed.

WARNING!

English

SUB 615 - SUB618 Cod. 420120251 REV. 1.0

INPUT, OUTPUT AND CONTROL SECTION

1. INPUTS

XLR (balanced) input connectors. They may be used for mono or stereo connection. For further details

concerning connection, refer to INPUT CONNECTIONS AND AUDIO DAISY CHAIN.

4. Outputs Mode

Selector allowing to set the type of output signal (Link/Xover). It acts on the daisy-chained signal from

OUTPUT connectors [2].

5. Polarity

and Subwoofer Mode buttons

Buttons allowing to control (Normal or Reverse) Polarity and the type of output ltering (Flat, i.e. without

equalisation, Boosted, i.e. low frequencies are emphasised).

3. Subwoofer Level

Rotary switch to adjust output audio level.

2. OUTPUTS

XLR (balanced) output connectors. They may be used for mono or stereo connection. For further details

concerning connection, refer to INPUT CONNECTIONS AND AUDIO DAISY CHAIN.

6. LED (Limiter, Signal/ON)

Indicator LEDs. The Limiter LED turns on when the internal protection circuit is triggered, while Signal/ON

indicates subwoofer power-up as well as the presence of an input audio signal.

English

25

SUB615 - SUB618 Cod. 420120251 REV. 1.0

7. MAINS INPUT

VDE connector input. For connection to the mains, through the cable supplied with the device.

The FUSE section contains mains fuse housing.

8. POWER

Switch for turning device ON or OFF.

POWER SUPPLY UNIT SECTION

SUB 615 - SUB618 Cod. 420120251 REV. 1.0

The package of SUB 615 / SUB 618 subwoofer contains:

• 615 or 618 subwoofer

• VDE power cable

• quick start user manual and warranty documents in hard copy

2. FIRST POWER-UP

CONFIGURATION AND OPTIMISATION

SUB 615 and SUB 618, used in a stand-alone conguration, are characterised

by omnidirectional sound emission. This feature is emphasised in case of low

frequencies, while it decreases as frequency

increases.

For subwoofer use optimisation in given congurations, the control panel

displays the following:

• Outputs Mode:

1. Link (the signal present at OUTPUTS is the one applied to the woofer)

2. Xover (the signal present at OUTPUTS is ltered with a crossover

frequency of 120 Hz, for daisy chain to a speaker, such as B-HYPE and

OPERA)

• Polarity:

1. Normal (audio signal normal polarity)

2. Reverse (reverse polarity, useful for wavefront optimisation through

acoustic wave phase reversal)

• Subwoofer Mode:

1. Flat (sound emission without equalisation)

2. Boosted (sound emission is emphasised in case of low frequencies)

Before power-up, set Subwoofer Level selector [3] to 0 dB (Mono or Stereo,

depending on the conguration).

INPUT CONNECTIONS AND AUDIO DAISY CHAIN

CASE A (MONO connection) between subwoofer and

speaker (examples: gure 1, gure 2):

According to the specic conguration (mono or stereo), one or two cables (not supplied) are required at

input and at daisy chain. XLR connectors are required.

In the event of a MONO connection between

subwoofer and speaker:

1. Connect mixer output to subwoofer INPUTS 1

connector

2. Connect subwoofer OUTPUTS 1 connector to

speaker input.

3. For each speaker, select the type of input

impedance on LINE.

4. For each channel in the conguration, set

subwoofer OUTPUTS MODE [4] to XOVER, in

order to daisy-chain a signal having a crossover

frequency of 120 Hz to the speaker.

SUB 615 - SUB618 Cod. 420120251 REV. 1.0

Figure 3

CASE B (STEREO connection between a subwoofer and 2 speakers, gure 3)

1. Connect mixer L, R outputs to subwoofer INPUTS 1 and 2 respectively.

2. Daisy-chain the signal to the speakers, connecting OUTPUTS 1 to LH speaker Input, OUTPUTS 2 to RH

speaker Input.

3. Select the impedance for each speaker (“LINE” type).

4. Set subwoofer OUTPUTS MODE [4] to XOVER, in order to daisy-chain a signal having a crossover

frequency of 120 Hz to the speaker.

3. USAGE EXAMPLES

• Types of installation other than those here described are not allowed.

• Never use the handles to suspend the subwoofer

• Always check that the positioning is stable and that the installation does not pose a danger to

people, animals or property.

USAGE ON SUBWOOFER WITH POLE

TELESCOPIC

It is possible to use only one speaker mounted on a 35 mm

diameter pole (e.g. series: OPERA, B-HYPE). The reference

accessory is DS-2 (telescopic pole).

The maximum allowed height between the speaker base and

the oor is 165 cm, except for B-HYPE 15 and OPERA 15, whose

maximum allowed height is 120 cm.

FLOOR USAGE

615 and 618 subwoofers may be used directly on the oor (see

gure opposite showing a usage example.)

USAGE WITH SPEAKER IN A STACK

A speaker may be installed directly on 615 or 618 subwoofer

by means of a DS2-S 35 mm diameter mini-pole (e.g. series:

INGENIA, B-HYPE, OPERA).

INGENIA series allows for 2 stacked speakers (specic accessories:

LP-IG and GSA-IG/GSA-IGA). In particular, in the event of 2 stacked

INGENIA IG3T or 2 stacked INGENIA IG4T, fastening by means of

additional belts is required to

ensure stable and safe installation.

5. TROUBLESHOOTING

1. Check that power supply is present upstream of the installation.

2. Ensure that the power supply cable with VDE connector is properly plugged in.

1. Check that the input connection of the audio signal is correctly performed.

2. Check the cables for damage.

3. Ensure that the mixer or audio source is on and an output signal is present.

4. Check the general level through the “Subwoofer Level” control.

1. Check the cables for damage and replace them as required (a damaged cable may lead to signal loss or

alteration).

2. Ensure that Outputs Mode, Polarity and Subwoofer Mode selection settings are correct according to the

selected conguration.

The subwoofer will not turn on:

The subwoofer turns on but produces no sound:

Speaker sound is inappropriate:
