Can I replace the tubes myself in the FT1?
FT1 tubes are matched and calibrated in an involved process carried out during production.
As much as we would love to accommodate customers replacing their own tubes in this product it's not feasible for us to provide this support directly to customers due to this calibration process and other possible complications, including voiding the warranty. Please do feel assured that even outside the warranty period, we will continue to offer replacement service of any tubes should issues arise as a separate service.
If this feature is important to you for future products we'd love to hear from you on the feature requests area on our discord page!
How many channels can a single FreqTube FT1 process?
Each FT1 offers 4 mono channels or 2 stereo channels, thanks to its four discrete vacuum tubes. This multi-instance design is ideal for parallel processing or routing individual stems—drums, vocals, synths—with precision.
Are the FreqTube FT1 channels stereo or mono?
Each channel is mono and independently operable. You can link channels for stereo use or run four mono paths in parallel, giving maximum routing flexibility.
Is FreqTube FT1 also an audio interface?
No. FT1 is not a standalone interface—it works alongside your existing audio interface to bring real analog processing into your DAW with full plugin-based control.
Are the I/O jacks balanced?
Yes. FT1 uses balanced analog I/O jacks, ensuring high-quality, low-noise signal transmission throughout your chain. But you can also use unballanced, just beware of the small gain reduction.
Can I use FreqTube FT1 with USB hubs or adapters?
We recommend a direct USB-C connection to your computer. If using a hub, only use validated hubs, such as the SATECHI 4-Port USB-C Hub (10Gbps, Model B0DHBFDFWC). Ensure no other devices are connected to the same hub.
FT1 shows “Device is Unreachable” or “Waiting for Connection”—what now?
Try these:
- Reboot the FT1 and change USB ports
- Ensure DAW and OS are fully updated
- Check your DAW’s audio settings
- Disconnect other USB devices to reduce bandwidth load
Should I turn off my FreqTube unit when I don't use it?
We use high-end tubes, and the tubes, has a quick warm-up cycle at power up. This prolongs the tubes life expectancy and you can therefore without worrying power off the machine when you dont use it. But we also have a built-in power down function that puts the Freqtube in a sleepmode when no plugin is detected.
Which tubes are inside and what voltage does it run at?
Four independent tube channels, 2 premium tube types, specifically two E83CC and two 12AT7 tubes, with parallel and primary analog processing paths for each channel with true analog mixing.
Supporting up to 192kHz sample-rate with ultra low jitter pro converters built in coupled directly into the analog circuit for optimal performance.
