SUB 600 series Cod. 420120251 REV. 1.1

FEATURES OF THE AMPLIFIER AND CONTROL SECTIONS

Class D digital custom amplifier, SMPS, is at the heart of SUB 600.

The system is silent and is controlled by a dedicated DSP that manages the different parameters.

The sound amplification power is 600 W RMS.

The amplifier panel is made up of:

• Input, Output and Control Section
  Power Supply Unit Section

WARNING!

• Never attempt to disassemble the amplifier in any way.
• In case of overheating, the audio volume is gradually reduced until module thermal stabilization. The level is automatically 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.

WARNING!

• 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.

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.

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.

3. Subwoofer Level

Rotary switch to adjust output audio level.

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 filtering (Flat, i.e. without equalisation, Boosted, i.e. low frequencies are emphasised).

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.

SUB 600 series Cod. 420120251 REV. 1.1

POWER SUPPLY UNIT SECTION

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.

2. FIRST POWER-UP

The package of SUB 600 subwoofer contains:

• 612 or 615 or 618 subwoofer
  VDE power cable
• quick start user manual and warranty documents in hard copy

CONFIGURATION AND OPTIMISATION

SUB 600, used in a stand-alone configuration, 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 configurations, the control panel displays the following:

• Outputs Mode:

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

• Xover (the signal present at OUTPUTS is filtered with a crossover frequency of 120Hz , 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)

3. Subwoofer Mode:

4. Flat (sound emission without equalisation)

5. 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 configuration).

SUB 600 series Cod. 420120251 REV. 1.1

INPUT CONNECTIONS AND AUDIO DAISY CHAIN

According to the specific configuration (mono or stereo), one or two cables (not supplied) are required at input and at daisy chain. XLR connectors are required.

CASE A (MONO connection) between subwoofer and speaker (examples: figure 1, figure 2):

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

Figure 1

SUB 600 series Cod. 420120251 REV. 1.1

CASE B (STEREO connection between a subwoofer and 2 speakers, figure 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 120Hz to the speaker.

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".

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.

FLOOR USAGE

SUB 600 may be used directly on the floor (see figure opposite showing a usage example.)

USAGE WITH SPEAKER IN A STACK

A speaker may be installed directly on the 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 (specific 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.

USAGE ON SUBWOOFER WITH POLE TELESCOPIC

It is possible to use only one speaker mounted on a 35mm 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 floor is 165~cm except for B-HYPE 15 and OPERA 15, whose maximum allowed height is 120~cm .

4. ACCESSORIES

To completion of the series, the following accessories are provided as options:

Protection covers

Check the new compatible accessories on: www.dbtechnologies.com

5. TROUBLESHOOTING

The subwoofer will not turn on:

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.

The subwoofer turns on but produces no sound:

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.

Speaker sound is inappropriate:

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 configuration.
