Q: How to configure the DVA K5 in Left-Right stereo with multiple speakers?

The issue arises from a fundamental incompatibility: the DVA K5 operates exclusively in mono , not in stereo. There is only one audio input (balanced female XLR) and one link output (male XLR). Therefore, the module cannot separately manage a left channel and a right channel. When you connect the Left and Right outputs of your console to two different DVA K5 units, only the first input actually receives the signal. That’s why only the Right side works - and why reversing the connections doesn’t change anything: it’s not a defect, it’s the product design. Solution To utilize your setup of 6 speakers, you need to: Mix your Left + Right signals in mono before the DVA K5 (using a small audio mixer or the mono outputs of your console if available) Send this single mono signal to the first chain of 3 DVA K5 units The other three DVA K5 units in cascade (output of the first connected to the input of the second, etc.) will receive the same mono signal According to the manual, the SPEAKER COUPLING ring must be adjusted to the position corresponding to your 6 modules (see configuration sections), to maintain a uniform frequency response across the entire line array.

Q: Why do only certain speakers receive the signal?

Question 1

How to configure the DVA K5 in Left-Right stereo with multiple speakers?

Accepted Answer

The issue arises from a fundamental incompatibility: the DVA K5 operates exclusively in mono, not in stereo. There is only one audio input (balanced female XLR) and one link output (male XLR). Therefore, the module cannot separately manage a left channel and a right channel.

When you connect the Left and Right outputs of your console to two different DVA K5 units, only the first input actually receives the signal. That’s why only the Right side works - and why reversing the connections doesn’t change anything: it’s not a defect, it’s the product design.

Solution

To utilize your setup of 6 speakers, you need to:

Mix your Left + Right signals in mono before the DVA K5 (using a small audio mixer or the mono outputs of your console if available)
Send this single mono signal to the first chain of 3 DVA K5 units
The other three DVA K5 units in cascade (output of the first connected to the input of the second, etc.) will receive the same mono signal

According to the manual, the SPEAKER COUPLING ring must be adjusted to the position corresponding to your 6 modules (see configuration sections), to maintain a uniform frequency response across the entire line array.

Question 2

Why do only certain speakers receive the signal?

Accepted Answer

The DVA K5 operates in mono only. If only certain speakers (for example, three on one side) receive the signal, this generally indicates a problem in the daisy chain.

Daisy Chain Configuration of the DVA K5

The modules must be connected linearly as follows:

The OUTPUT/LINK output of the first module must be connected to the BALANCED AUDIO input (balanced XLR) of the next module
Each module receives and transmits the same mono signal to the following modules
The manual recommends the exclusive use of Neutrik(R) connectors to ensure optimal reliability

Possible Causes and Solutions

Poor daisy chain wiring - Check that the chain is complete: the OUTPUT/LINK output of each module must be connected to the BALANCED AUDIO input of the next, without jumps or interruptions
Damaged or oxidized cables - Inspect the Neutrik(R) XLR connectors for signs of corrosion or poor contact. Damaged cables cause loss or distortion of the audio signal
Non-Neutrik(R) cables - Use only cables with Neutrik(R) connectors as recommended by the manufacturer

If the problem persists after checking the wiring and replacing the cables, the failure may be hardware-related in one of the modules.

Question 3

Where is the On/Off switch of the DVA K5?

Accepted Answer

The On/Off switch of the DB Technologies DVA K5 uses the standard symbols "I" (on) and "O" (off). According to the manual, you need to set this switch to the "I" symbol to turn on the speaker.

Although the manual mentions this switch in the troubleshooting section, the exact location on the panel (front, back, or side) is not documented in the PDF of this manual. Generally, on active speakers of this type, the switch is most often found on the back panel or on the side of the device. Check the back/side area of the DVA K5 for these I/O symbols.

Question 4

I have 4 DVA K5 with the same settings, but one of them reproduces the highs very weakly. Where could this problem come from?

Accepted Answer

If one of your DVA K5 speakers reproduces the highs very weakly while the other three are identical and well adjusted, there are several possible causes to check in this order:

1. Check the HIGH FREQUENCY COMPENSATION setting

The DVA K5 has a DSP ring dedicated to controlling high frequencies with 8 different positions depending on your setup (stacked or flown) and the distance to the audience. Even if you thought you had the same setting on all four speakers, check that the compensation ring is exactly in the same position on all modules. If it is only off by one position, this can create an audible asymmetry in the highs.

2. Test the audio cables

Perform a swap test: connect the audio cable from the faulty speaker to another (functional) speaker, then connect the cable from a functional speaker to the problematic speaker. If the fault follows the speaker, it is a hardware issue. If the fault follows the cable, it is an audio connection problem. Also check the XLR connectors for signs of oxidation or poor contact.

3. Check the tweeter

Once the setting and the cable have been ruled out, the cause is likely a defect in the tweeter or the high frequency module of this speaker (manufacturing defect, damage, obstruction). Visually inspect the tweeter to see if there is dust, a torn diaphragm, or a damaged cover that could be attenuating the highs.

Note: The DVA K5 also has a SPEAKER COUPLING setting to adjust the bass according to the number of modules (positions A to G). Also check that this setting is identical on all four speakers, although it mainly affects the low frequencies.
