d&b audiotechnik Infra Sub
Plan low-frequency extension as part of the sound system. To select a cabinet, amplification and settings, we first need to identify the model behind the Infra Sub reference and review its integration with the main system.
Identification and scope
- Manufacturer or brand
- d&b audiotechnik
- Equipment name
- d&b audiotechnik Infra Sub
- Location
- Ask about availability and location
- Supply for the event
- Ask about options for the planned date and scope
- Configuration or function
- Low-frequency extension; the Infra Sub name does not identify the exact model.
You can start with the type of event, the space and the result you want, even if you have not chosen a model yet. We will review a configuration and supply options.
Details for planning the low-frequency system
- Full cabinet and proposed amplification models, applicable documentation and intended configuration.
- Signal path from mixing to amplification, assigned channels and relationship with the main system.
Identify the cabinet and its configuration
Record the model and markings of each cabinet, along with the intended amplifier and processing. Find the documentation for those references before assigning connections, presets or limits to the assembly.
The Infra Sub name does not confirm that this is another model linked on this page. Related equipment pages help expand the inquiry; equipment and accessories are selected for the specific configuration.
Prepare the low-frequency system review
| Point | What to record | How to proceed |
|---|---|---|
| Identification | Cabinets, amplification and documentation for the intended references | Confirm the configuration allowed by its documentation |
| Signal path | Source, outputs, processing and assigned channels | Review patching and controls shared with the main system |
| Integration | Space, intended placement and role within the system | Define the proposal and listening check for the event |
If the response differs from what was expected, record which section passes signal, what the amplification indicates and which configuration is selected. Once the model is identified, consult the corresponding procedure; crossover, delay or polarity values are not assigned from the generic name.
Topics to discuss
- Patching and destinations
- Coverage and listening
- Control and configuration
- Troubleshooting by signal-path section
Before applying settings, identify the complete equipment variant and consult its documentation.
