Frequently Asked Questions - DVA K5 DB Technologies

How to configure the DSP for a line array of 4 K5 modules?

Set the SPEAKER COUPLING ring to position B (2 to 4 speakers). For HIGH FREQUENCY COMPENSATION, choose the position based on the installation (stacked or flown) and the distance to the audience.

What accessories are needed to suspend the DVA K5?

You will need a fly-bar DRK-10 or DRK-20 (or motorized DRK-20M). Also use the dBTechnologies Composer software to check loads.

The speaker does not turn on, what should I do?

Check that power is present upstream, that the power cord is properly inserted, and that the ON/OFF switch is set to 'I'. If the problem persists, check the fuse.

Can I use the DVA K5 alone or must I use it in a line array?

The DVA K5 can be used alone or in a line array. When used alone, set the SPEAKER COUPLING ring to A (1 to 2 speakers) and HIGH FREQUENCY COMPENSATION to 1 (stack) or a flown position depending on the installation.

What type of audio cable should be used to connect the modules?

Use high-quality balanced XLR cables (Neutrik® recommended). For audio linking, connect the OUTPUT/LINK of one module to the BALANCED AUDIO input of the next.

How to update the firmware of the DVA K5?

Connect a mini-B USB cable to the SERVICE DATA port on the rear panel and to a computer. Download the firmware from dbtechnologies.com (DOWNLOADS section) and follow the instructions.

What is the maximum power consumption under normal operation?

Under normal conditions (1/8 power), consumption is about 3 A at 220-240 V. Under maximum operation (clipping), it can reach 8 A. Inrush current is 18.3 A.

The sound is distorted, what should I check?

Check that the LIMITER indicator is not lit. Adjust the input sensitivity (Audio Input Sensitivity). Check the cables (replace if damaged). Make sure the LINE-MIC switch is correct.

Can I mount the DVA K5 on a stand or a pole?

Yes, with the DSA-4 accessory. You can mount up to 2 modules on a standard stand (35 mm diameter). The maximum height from the ground is 130 cm.

CONFIGURATION AND OPTIMISATION WITH DSP IN LINE-ARRAY

The use of a line-array provides multiple benefits in various contexts; in particular:

• Homogeneous SPL along the speaker front direction; the effect is particularly noticeable over medium to long distances
• directive sound behaviour, allowing to accurately focus the sound on the audience, avoiding unnecessary dispersions in areas where acoustic coverage is not required
  • The line-array optimisation takes into account the system behaviour with respect to the frequency:
• as distance from the line-array increases, air attenuation increases as well. This particularly applies to high frequencies.
  • as the angle of the line-array components increases decreases mid-frequency phase coupling
  • as the number of line-array modules low frequencies add together in an acoustically coherent fashion

The DSP-managed control functions allow to optimise the line-array sound configuration of the DVA K5 modules. The user interface is simple and intuitive. It includes two rotary encoders installed in the “DSP Preset” (4) section and the reference label shown below:

- Turn the "SPEAKER COUPLING" rotary encoder to set the number of modules included in the line array. This rotary encoder affects the low frequencies and must be turned to the following position:

• A - 1 to 2 speakers
• B - 2 to 4 speakers
• C - 5 to 6 speakers
• D - 7 to 8 speakers
• E - 9 to 10 speakers
• F - 11 to 12 speakers
• G - 13 speakers and beyond

5. TROUBLESHOOTING

The speaker doesn't turn on:

1. Check that the power supply upstream of the system is working properly
2. Check that the power cord is properly plugged
3. Check that the ON/OFF selector is turned to "I".

The speaker turns on but it doesn't output any sound:

1. Check that the input connections of the main audio signal and of the auxiliary one, if any, have been performed properly
2. Check that the cables in use are not damaged
3. Check that the mixer or the audio source are on and that they clearly indicate the presence of an output signal to the speaker.
4. Check that the level of the main audio volume and of the auxiliary one, if any, are set to an appropriate value.

The speaker outputs a distorted sound:

1. Check that the Audio Input Sensitivity rotary encoder is set on the correct value (0 dB). It should be noted that if the LIMITER LED is on, it indicates the speaker is operating under distorting conditions.
2. Check that the cables in use are not damaged; should that be the case, replace them (a damaged cable may result in a signal loss or alteration).
3. Check that the LINE-MIC switch matches the actual input connection.
4. Check the settings of the rotary encoder DSP preset affecting the output frequency response. To this purpose please refer to section FIRST SWITCH-ON.
