1. GENERAL INFORMATION

WELCOME!

Thanks for purchasing a product designed and developed in Italy by dBTechnologies! This ergonomic and versatile active speaker is the result of a long experience in the sound reinforcement industry, making use of optimized sound, electronic and material research solutions.

PRODUCT OVERVIEW

The new active KL speakers are equipped with a 1" compression driver (coil: or coil 1.35") for the high section. One 10", 12" and 15" transducer (coil: 2" or 2.5") on KL10, KL12, KL15, respectively, completes the effective acoustic performance levels on medium-low frequencies. These speakers main features include:

• an ergonomic, compact and versatile project that can be used in monitoring for small live contests
• extensive input equipment, including Bluetooth® for maximum mobile connectivity
• reliable, silent digital amplifier
• input type versatility, for instance for the amplification of a voice and an instrument at the same time
• output connection versatility, for the audio link of the mixed signal or
• selectable preset links with different equalizations for different types of use

USER REFERENCE

To make the most of your KL amplifier, we recommend that you:

• read the quick start user manual included in the package and this user manual thoroughly and keep this manual during the whole life of the product.
• Register your product at http://www.dbtechnologies.com under "SUPPORT".
• keep proof of purchase and WARRANTY (User manual "section 2").

MECHANICAL AND ACOUSTICAL FEATURES

DIMENSIONS

KL SERIES Code 420120347 REV. 1.0

It is possible to connect up to 2 wired inputs in the input and control section at the back of the speaker, in addition to the Bluetooth® connection.

The Line/Mic input selection is set to select the impedance to line level or microphone level.

The Out Routing Selector (5) in "Link" position allows providing the output of the second speaker with only the signal coming from the CH1 channel. In the "Mix" position, it allows channel mixing.

Adjust the level of each connected channel.

Once inputs are connected, select the correct DSP preset (3).

USING THE BLUETOOTH®

To perform Bluetooth ^® synchronisation, first enable its function on the mobile device to be connected.

Then, on the KL speaker, press the PAIR key; the relevant LED flashes. At this point, the model name will appear on the mobile device: enable the connection, the relevant LED becomes steady.

KL SERIES Code 420120347 REV. 1.0

3. USAGE EXAMPLES

• Types of installation other than those here described are not allowed.
• Never use the handles to suspend the speaker
• Always check that the positioning is stable and that the installation does not pose a danger to people, animals or property.
• Perform the installation on a flat, not tilted surface, otherwise an additional safety fastening is mandatory.

INSTALLATION ON STAND

1 KL speaker can be installed on a tripod stand, coming as standard option (accessory SSB2) with a 35 mm diameter pole. The maximum allowed height between the speaker base and the floor is 150 cm for KL10, KL12. KL15.

ATTENTION!

- Use a suitably sized stand with the central leg pointing forward to provide appropriate stability.

INSTALLATION ON SUBWOOFER

Through the installation with the DS2-S accessory, it is possible to use 1 KL directly on subwoofer provided with M20 flange. For further information, refer to the relevant accessory manual.

INSTALLATION ON SUBWOOFER WITH POLE

It is possible to use only one speaker mounted on a 35 mm diameter pole. The maximum allowed height between the speaker base and the floor is 150 cm for KL10, KL12, KL15. In case of DVA S08DP or SUB 28D subwoofer, an additional mechanical fastening or a belt fastening is required to correctly and safely fix the installation.

5. TROUBLESHOOTING

The loudspeaker 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 speaker turns on but produces no sound:

1. Check that the input connections of the audio signal (CH1 and/or CH2) are carried out correctly.
2. Check the cables for damage.
3. Ensure that the mixer or audio source is on and an output signal is present.
4. Check that the input levels (CH1 and/or CH2) are appropriate.

Speaker sound is distorted or not sufficient:

1. Adjust the first source volume, then set the input (CH1 and/or CH2) gain to an adequate level. Check the cables for damage and replace them as required (a damaged cable may lead to signal loss or alteration).
2. Check that the input selection settings (CH1 -> Mic/Line, CH2 -> Line/Instr) are correct with respect to the source
3. Check that the "DSP preset" settings are suitable for the use selected.

A background hum can be heard:

1. Disconnect all connected devices and turn power supply off.
2. Check that the Ground Lift switch is correctly set.
3. Check the connection cables for damage.
4. Connect cables again and turn speaker on.
