Q: Does the WL-T transmitter fit any guitar?
A:
The WL-T transmitter fits into standard guitar jacks including Stratocaster type, Telecaster type, Les Paul type, SG type, acoustic-electric guitar type, end-pin jack, etc.
Please note: It may not function properly with some guitars/jack plug types.
The functionality of the following types of guitars will be limited.
- Guitars with 1/4" stereo (TRS) phone output jack.
* Only the signal from the left (tip) channel will be output.
The following types of guitars are not supported.
- Guitars with no sufficient space (cylindrical space with 18.5 mm diameter and 5 mm depth) to attach the transmitter around the input jack.
- Guitars with special electrical wiring.
- Some guitars with active pickups *1
- YAMAHA Silent Guitar *2
*1 The typical TRS output jack wiring of guitar active circuit is audio to tip, ground to sleeve, and battery ground to ring. In rare cases where ring and sleeve are wired reversely, the guitar active circuit doesn't work properly with the WL-T.
*2 It is not compatible with the WL-T due to a special wiring specification.
The transmitter (WL-T) can be used with the KATANA-AIR, WL-20, WL-20L, and WL-50.
The detection conditions when the transmitter changes to standby mode differ according to the device used.
The respective conditions set automatically when carrying out auto wireless connection are as follows.
- KATANA-AIR: Vibration detection
- WL-20, WL-20L, WL-50: Sound detection
Replacement is not possible.
Q: What can be accomplished when the KATANA-AIR is connected to a computer via USB?
A:
You can record audio from the KATANA-AIR on the computer, and monitor audio from the computer via the KATANA-AIR.
Q: During recording or playback on a digital audio workstation (DAW) via a USB connection, is reamping possible?
A:
Yes, it is.
When recording dry audio on a DAW, use the input-device settings for the DAW you're using to select "KATANA-AIR Secondary" (Windows) or "KATANA-AIR Output 3,4" (Mac).
When performing playback without applying KATANA-AIR effects, use the output-device settings for the DAW you're using to select "KATANA-AIR Primary" (Windows) or "KATANA-AIR Stereo Out (1,2)" (Mac).
Q: Is it possible to take guitar audio recorded on a computer, apply KATANA-AIR effects, and re-record it on a DAW?
A:
Yes, it is.
In such cases, use the input- and output-device settings for the DAW you're using to make the settings as follows.
Playback software (output device)
Select "KATANA-AIR Secondary" (Windows) or "KATANA-AIR Input 3,4" (Mac).
Recording software (input device)
Select "KATANA-AIR Primary" (Windows) or "KATANA-AIR Input 1,2" (Mac).
Yes, it is.
In such cases, use the output-device settings for the DAW you're using to select "KATANA-AIR Secondary" (Windows) or "KATANA-AIR Input 3,4" (Mac).
Q: Can the transmitter (WL-T) be used while it is charging?
A:
No, it cannot be used. Use it after charging.
Q: The sound from another guitar is heard.
A:
Are there another KATANA-AIR and transmitter nearby?
Insert the transmitter into the TRANSMITTER IN jack, and use once the BATTERY indicator has changed from flashing in orange to lighting up steadily or going dark.
Q: How can I use multiple wireless systems at the same time?
A:
To prevent interference in the wireless communication, carry out the following procedure.
- Turn off the power to the BOSS wireless systems.
- Turn on the power to any non-BOSS wireless systems, and ensure that sound is played without problem.
- First BOSS wireless system
Turn on the power to the receiver, insert the transmitter, and carry out the Auto Wireless Connection procedure.
- Insert the transmitter into the guitar, making the BATTERY indicator light up.
- Second and subsequent BOSS wireless systems
Repeat steps 3 and 4.
Is the KATANA-AIR running on battery power only?
The remaining battery charge in the KATANA-AIR might be low.
Replace with fresh batteries or connect an AC adapter.
Q: The unit does not appear in the terminal's Bluetooth devices.
A:
On the KATANA-AIR, is Bluetooth turned off (the "Bluetooth" indicator is dark)?
Reset the power to the KATANA-AIR, or press and hold the Bluetooth button to activate Bluetooth.
The operating system displays the following devices.
Bluetooth audio function: "KATANA-AIR Audio"
Bluetooth MIDI function: "KATANA-AIR MIDI" (*)
* "KATANA-AIR MIDI" is visible in the operating system's settings, but do not attempt connection to it.
Use the settings in BOSS TONE STUDIO or another application to make the selection.
For details about making a Bluetooth connection, refer to "Connecting the iOS/Android BOSS TONE STUDIO App and the KATANA-AIR."

A:
Use the settings in BOSS TONE STUDIO to make a Bluetooth connection.
For details, refer to "Connecting the iOS/Android BOSS TONE STUDIO App and the KATANA-AIR."
Q: The transmitter's BATTERY indicator is flashing in red. What should I do?
A:
A charging error has occurred. First, check the following points.
The transmitter's internal temperature might be elevated.
Charging is sometimes paused to protect the rechargeable lithium-ion battery.
When the internal temperature falls, the BATTERY indicator changes to lighting up steadily in orange, and charging resumes.
Detach the transmitter from the receiver and wait a short while before resuming use.
The ambient temperature might be 35 deg. C or higher.
Charging is sometimes paused to protect the rechargeable lithium-ion battery.
Use in the recommended ambient temperature range of 10 deg. C to 30 deg. C.
Q: How long does the transmitter take to charge?
A:
Charging time can vary according to the remaining battery charge and the charging environment.
For Reference
The following are approximate charging times when charging is performed under the conditions described.
- When the transmitter's battery is completely depleted
- Operated using the AC adapter included with the KATANA-AIR (PSB-12U)
40 deg. C
Charging via USB: After approximately 10 minutes, the indicator flashes in red, and charging remains paused thereafter (because charging is inhibited at high temperatures).
Charging via the TRANSMITTER IN jack: After several minutes, the indicator flashes in red, and charging remains paused thereafter (because charging is inhibited at high temperatures).
35 deg. C
Charging via USB: After approximately 1 hour, the indicator flashes in red (for several seconds), subsequently lighting up in orange, and charging is fully completed in a total of approximately 2 hours.
Charging via the TRANSMITTER IN jack: After approximately 10 minutes, the indicator flashes in red (for several seconds), subsequently lighting up in orange, and low-speed charging is performed. At approximately 5 hours, charging is about 90% complete.
30 deg. C
Charging via USB: The battery is fully charged in approximately 2 hours.
Charging via the TRANSMITTER IN jack: After approximately 30 minutes, the indicator flashes in red (for several seconds), subsequently lighting up in orange, and low-speed charging is performed. At approximately 5 hours, charging is about 95% complete.
25 deg. C
Charging via USB: The battery is fully charged in approximately 2 hours.
Charging via the TRANSMITTER IN jack: At about 1 hour, the indicator momentarily lights up in red or in green, or flashes in red for several minutes, and subsequently lights up in orange and low-speed charging is performed. The battery is fully charged in approximately 4 hours.
5 deg. C
Charging via USB: The battery is fully charged in approximately 2 hours.
Charging via the TRANSMITTER IN jack: The battery is fully charged in approximately 2 hours.
When the transmitter is charging while connected to the TRANSMITTER IN jack on the KATANA-AIR, sound drop-out can occur depending on the state of usage of nearby Wi-Fi devices using the 2.4 GHz band.
* The influence of this effect is reduced when the transmitter (WL-T) is charged using a commercially available USB cable.
If you want to perform charging via the TRANSMITTER IN jack when using Bluetooth, try the following.
Bluetooth
Bluetooth devices are typically equipped with features to avoid frequency interference, and the KATANA-AIR also automatically switches to using a frequency subject to less interference with the frequencies used by Wi-Fi and when charging the transmitter. Though the switching time differs depending on the connected devices and the signal strength of the other equipment, operation tends to become more stable within several minutes. Wait for a short while.
Radio-wave interference
Try moving any Wi-Fi routers, Bluetooth devices, and other equipment that uses the 2.4-GHz band away from the KATANA-AIR and the smartphone.
* Equipment that uses the 2.4-GHz band include wireless mouse devices.
Placement of the KATANA-AIR
It is possible to change the situation by placing the KATANA-AIR and the smartphone closer to each other and by moving the KATANA-AIR slightly away from a wall, so try varying the positioning.
