Ideal Applications

Professional Corporate AV Systems

Perfect for modern corporate meeting rooms and conference centers integrating analog microphones, wireless receivers, or legacy audio equipment into a Dante® network infrastructure. Connect wireless mic receivers or podium microphones to your networked DSP, mixer, or recording system while maintaining centralized control. The dual network redundancy ensures uninterrupted audio during critical presentations and video conferences, while PoE+ power eliminates the need for separate power outlets at podium or table locations.

Live Sound & Concert Venues

Essential for live performance environments where analog stage equipment needs to interface with a Dante® network backbone. Connect stage microphones, DI boxes, or instrument preamps to your digital mixing console over standard network cabling, reducing stage box requirements and simplifying cable runs. The 8-band parametric EQ on each input allows for precise tonal shaping before signals reach the mix console, while configurable delay compensation ensures perfect time alignment across your system.

Broadcast & Production Studios

Ideal for radio stations, podcast studios, and video production facilities requiring reliable analog-to-Dante® conversion with professional DSP. Interface legacy broadcast consoles, analog microphone preamps, or outboard processing gear with modern Dante®-based infrastructure. The dual network configuration provides broadcast-critical redundancy, automatically switching to the secondary network if the primary fails, ensuring uninterrupted on-air operation.

Houses of Worship

Designed for churches, temples, and religious facilities integrating traditional audio systems with modern networked AV. Connect pulpit microphones, choir mics, or instrument inputs to your Dante® network for distribution to multiple zones, streaming systems, and recording equipment. The compact half-rack form factor fits easily in podiums or wall-mounted racks, while phantom power support accommodates condenser microphones without additional equipment.

Educational Institutions

Perfect for schools, universities, and training facilities requiring flexible audio routing between classrooms, lecture halls, and control rooms. Bridge analog sources like podium microphones, document cameras with audio, or legacy PA systems to a centralized Dante® network for recording lectures, streaming classes, or routing to multiple rooms. PoE+ power simplifies installation in classrooms where power outlet access is limited, reducing installation complexity and cost.

Frequently Asked Questions

Does the VLDT-XL22DB work with non-Dante audio equipment?

Yes, that's its primary purpose. The VLDT-XL22DB bridges analog audio equipment (microphones, mixers, wireless receivers, legacy gear) with Dante® network infrastructure. It converts analog XLR/TRS signals to Dante® digital audio and vice versa, allowing you to integrate traditional analog equipment into a modern networked AV system.

What is the difference between primary and secondary Dante networks?

The VLDT-XL22DB features dual Dante® network connections for redundancy. The primary network handles all audio traffic during normal operation. If the primary network fails (cable damage, switch failure, etc.), the unit automatically switches to the secondary network, ensuring uninterrupted audio in mission-critical applications like live events, broadcast, or corporate presentations.

Can I use this with Shure wireless microphone receivers?

Yes, the VLDT-XL22DB is perfect for connecting Shure wireless receivers (or any brand) to a Dante® network. Connect the receiver's XLR or TRS outputs to the VLDT-XL22DB inputs, and the audio is immediately available on your Dante® network. You can route it to mixing consoles, DSPs, recorders, or any other Dante®-enabled device. The adjustable input sensitivity accommodates both line-level and microphone-level signals.

Do I need phantom power for dynamic microphones?

No, phantom power (+48V) is only required for condenser microphones that need external power. Dynamic microphones (like Shure SM58, SM57) do not require phantom power and will work fine with it turned off. The VLDT-XL22DB allows you to enable/disable phantom power on each input independently, so you can use condenser mics on one input and dynamic mics on the other.

What DSP processing is available on the VLDT-XL22DB?

The integrated DSP provides comprehensive signal processing on both inputs and outputs: adjustable gain control, 8-band parametric equalizer with ±15dB gain per band (allowing precise frequency shaping), and up to 50ms of delay compensation for time alignment. All processing is configured through the web GUI or Dante® Controller, with settings stored in the device memory.

Can I power this unit using PoE instead of the DC adapter?

Yes, the VLDT-XL22DB supports PoE+ (IEEE 802.3at, Class 4) power through the primary Dante® network port. This eliminates the need for a separate power supply, simplifying installation in locations where AC outlets are limited or difficult to access. You can also use the included 12V DC power supply if PoE is unavailable. The unit automatically detects which power source is available.

Is the VLDT-XL22DB compatible with AES67 devices?

Yes, the VLDT-XL22DB supports both Dante® and AES67 audio protocols. AES67 is an interoperability standard that allows different networked audio systems to communicate. This means you can use the VLDT-XL22DB in mixed environments with devices from different manufacturers that support AES67, ensuring compatibility across diverse networked audio ecosystems.

What is the maximum distance I can run Dante network cables?

Dante® audio operates over standard Gigabit Ethernet, allowing cable runs up to 100 meters (328 feet) using Cat6, Cat6A, or Cat7 network cables. For longer distances, you can use Ethernet switches to extend the network. The dual network ports on the VLDT-XL22DB allow you to daisy-chain units or create redundant network paths for enhanced reliability.
