MECHANICAL AND ACOUSTICAL FEATURES

DIMENSIONS SUB 615 and S618 have the following sizes:

• SUB 615: 430 x 580 x 600 (mm)

• SUB 618: 500 x 625 x 690 (mm) English23 SUB615 - SUB618 Cod. 420120251 REV. 1.0 FEATURES OF THE AMPLIFIER AND CONTROL SECTIONS Class D digital custom amplier, 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 amplication power is 600 W RMS. The amplier panel is made up of: WARNING!

• Input, Output and Control Section

• Power Supply Unit Section

• Never attempt to disassemble the amplier 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! English24 SUB 615 - SUB618 Cod. 420120251 REV. 1.0

SUB 615 and SUB 618, used in a stand-alone conguration, 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 congurations, the control panel displays the following:

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)

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

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 conguration). EnglishFigure 2

CASE A (MONO connection) between subwoofer and speaker (examples: gure 1, gure 2): According to the specic conguration (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:

2. Connect subwoofer OUTPUTS 1 connector to

3. For each speaker, select the type of input

4. For each channel in the conguration, set

subwoofer OUTPUTS MODE [4] to XOVER, in order to daisy-chain a signal having a crossover frequency of 120 Hz to the speaker. Figure 1 English28 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

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. English29 SUB615 - SUB618 Cod. 420120251 REV. 1.0 POWER SUPPLY

POWER SUPPLY CONNECTION

For power supply connection of the device, insert the connector of the supplied cable into "MAINS INPUT" [7]. Then insert the plug into an outlet having a proper earth conductor. Switch the POWER selector [8] to "ON". English30 SUB 615 - SUB618 Cod. 420120251 REV. 1.0

• 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 (specic 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. English31 SUB615 - SUB618 Cod. 420120251 REV. 1.0 To completion of the series, the following accessories are provided as options:

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

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

selected conguration. The subwoofer will not turn on: The subwoofer turns on but produces no sound: Speaker sound is inappropriate: English33 SUB615 - SUB618 Cod. 420120251 REV. 1.0

• NOTE FOR INSTALLER: Values refer to 1/8th of power, under average operating conditions (music programme with occasional or no clipping). For any type of conguration we recommend to consider them as minimum sizing values. ** NOTE FOR INSTALLER: Values refer to 1/3rd of power, under heavy operating conditions (music programme with frequent clipping and limiter activation). In case of professional installations and tours we recommend sizing according to these values.
