MEMO
When the power is on, and a certain length of time elapses since
the unit was last played or operated, the unit automatically
enters standby mode. You can use a dedicated app (subsequently
referred to as BOSS TONE STUDIO) to change the time after which
the unit enters standby mode (p. 6).
In standby mode, the power automatically turns on if the
transmitter plugged into the guitar detects vibration (p. 5).
7 (Guitar Wireless) indicator
Indicates the status of the connection with the transmitter.
Indicator Explanation

Connected with the transmitter
When you play the guitar, the sound is heard
from the speaker.

Not connected with the transmitter
Alternatively, the guitar is connected to the
INPUT jack
* If the guitar is connected to the INPUT jack, the sound of the
INPUT jack takes priority.
8 TONE SETTING
[CH A], [CH B] buttons
Each of these buttons stores three sets of settings for all top panel
knobs (except the [MASTER] knob) and buttons (p. 6). Each time
you press a button, the color alternates between green, red, and
orange, and the settings change accordingly. If you hold down
a button for one second, the settings of the sound that you’re
currently hearing are overwritten onto the previously-stored
settings.
* You can make the settings back to the factory state by turning the
power on while holding down the [PANEL] button (p. 9).
[PANEL] button
Makes the unit sound using the current settings of the panel
knobs.
9 PHONES jack
Connect headphones here. You can obtain powerful guitar sounds
just as if you were playing through the speaker. By using BOSS
TONE STUDIO you can obtain the sound of dierent micing (LINE
OUT AIR FEEL, p. 6). To adjust the volume, use the [VOLUME] knob
along with the [MASTER] knob.
* If a plug is inserted in this jack, no sound will be output from the
KATANA-AIR EX’s own speaker. This is convenient if you don’t want
loud sound to be produced from the speaker, such as when you’re
practicing at night.
10 INPUT jack
Connect your electric guitar, bass guitar, or acoustic guitar.
* To prevent malfunction and equipment failure, always turn
down the volume, and turn o all the units before making any
connections.
11 TRANSMITTER IN jack

The rst time that you use the unit, power-on the KATANA-AIR EX
and insert the transmitter here to charge it.
NOTE
¹Do not insert anything other than a transmitter made by BOSS.
If you connect headphones, high-volume sound might be
emitted, or the headphones might be damaged.
¹The transmitter is equipped with a lithium-ion battery.
¹Even if you do not use the transmitter for an extended period of
time, you should charge it once every three months to prevent
the internal lithium-ion battery from degrading.
¹Ambient temperature range during charging: 5–35°C
However, in order to take full advantage of the rechargeable
lithium-ion battery’s performance, we recommend that you
charge it in a temperature range of 10–30°C.
If the temperature is outside the appropriate range, a charging
error might occur (the BATTERY indicator blinks red) and the
battery fail to charge (p. 10).
