With the current FreqSoft software, up to four FreqTube FT1 units can be used together, providing up to 16 independent tube channels.
When adding multiple units, use the Auto ID function in AnalogHub during the initial setup. This assigns a unique identifier—A, B, C, or D—to each connected FT1. Do not run Auto ID again unless you intentionally need to reassign the units.
Can I replace the tubes myself in the FT1?
No. The tubes inside each FT1 are carefully matched and factory-calibrated as part of the unit’s analog circuitry. User replacement is not recommended because the new tubes would require calibration, and opening or modifying the unit may void the warranty.
If a tube requires replacement, please contact Freqport Support. Tube replacement can also be provided as a paid service after the warranty period.
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 intended to replace your main audio interface. It is a dedicated USB-connected analog tube-processing system that works alongside your existing Core Audio or ASIO interface.
Audio passes between the DAW and FT1 through its dedicated USB connection, while the FreqTube plugin controls the analog processing, routing, automation, presets, and session recall.
Is there a software-only version of FreqTube FT1?
Yes. FreqTube FT1-EMU is an optional, separately available software plugin that recreates the FT1’s tube-circuit behavior using component-level SPICE modeling. It can be used as a conventional plugin without FT1 hardware.
When an FT1 hardware unit is connected, the same plugin can switch from software emulation to real analog tube processing while retaining the same controls and DAW workflow. This provides a convenient way to work in the box and move to genuine analog processing when required.
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?
A direct USB connection to the computer is strongly recommended for the most reliable audio and control performance.
If a hub is unavoidable, use only a suitable high-quality hub that has been validated for Freqport hardware, and avoid connecting other high-bandwidth devices to the same hub. If connection problems occur, connect FT1 directly to the computer before continuing troubleshooting.
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
- Try to manually close the AnalogHub software, and relaunch.
Should I turn off my FreqTube unit when I don't use it?
Yes. You can safely turn off the FT1 when it is not being used. The unit performs a brief tube warm-up cycle when powered on.
FT1 also includes an automatic power-down function that places the tube circuitry into a sleep state when no FreqTube plugin is active, helping to reduce unnecessary tube use..
Which tubes are inside and what voltage does it run at?
FreqTube FT1 contains four factory-matched and calibrated tubes arranged in two pairs:
- Two E83CC/12AX7 tubes
- Two 12AT7 tubes
The unit is powered by the supplied 24 W DC power adapter, which accepts 100–240 V AC mains power at 50/60 Hz. An internal high-voltage conversion circuit supplies the tube plate voltage. Use only the official Freqport power adapter.
