Amp 2

1. Connect the LINE OUT jack of amp #1 (the amp to which your guitar is connected) to the POWER AMP IN jack of amp #2.
2. Turn the [STEREO EXPAND] switch ON for both amps.

• None of the knobs on amp #2 respond in this case, except for the [MASTER] knob and the [POWER CONTROL] switch.
  19 POWER AMP IN jack
  Plug in to this jack for direct signal input to the power amp without going through the KATANA preamp. This lets you input sound from an external preamp or sounds you created using a multi-effect unit with a built-in amp simulator and the like, for example. When using the POWER AMP IN jack, the [PANEL] button lights up green (or red, when the [STEREO EXPAND] switch is ON). None of the knobs affect the sound input to this jack, except for the [MASTER] knob and the [POWER CONTROL] switch. Set the [STEREO EXPAND] switch to “OFF” if you are not using two KATANA units for a stereo connection. * You can’t use the POWER AMP IN jack and the INPUT jack at the same time. If a cable is connected to both jacks, the INPUT jack takes precedence.

Turning the power on/off

• Once everything is properly connected (p. 5­p. 7), be sure to follow the procedure below to turn on their power. If you turn on equipment in the wrong order, you risk causing malfunction or equipment failure.
• Before turning the unit on/off, always be sure to turn the volume down. Even with the volume turned down, you might hear some sound when switching the unit on/off. However, this is normal and does not indicate a malfunction.
  1. Make sure that the [MASTER] knob of this unit as well as the volume of any connected devices are set to “0”.
• Before connecting your instrument to the unit’s INPUT jack, set the [MASTER] knob to the minimum setting (far left).
  2. Turn on the power of this unit.

3. Turn on the power of the devices connected to the LINE OUT and PHONES/REC OUT jacks.
4. Adjust the volume levels of the devices.
Before switching off the power, lower the volume on all connected devices and then turn off the power of this unit (the reverse of when you switch this unit on). * If you need to turn off the power completely, first turn off the unit, then unplug the power cord from the power outlet. For details, read “To completely turn off power to the unit, pull out the plug from the outlet” in the Startup Guide (included).
Restoring the factory settings
Here’s how the settings stored in this unit can be returned to their factory- set condition (factory reset).
1. Without any other devices connected, turn on the power while holding down the [PANEL] button.
Each of the EFFECTS buttons continues blinking consecutively from the left. When the blinking stops, all of this unit’s settings return to the factory-set state.

• It takes approximately 30 seconds for the factory reset to be completed. Don’t turn off the power while the factory reset is in progress.

Wireless connection with a mobile device
Attach the BT-DUAL (sold separately) to the KATANA amp to wirelessly play back music that’s on your mobile device, or to edit the effects of this unit from the app on your mobile device. Note that the KATANA amp does not feature Bluetooth functionality. The BT-DUAL (sold separately) must be attached to use Bluetooth.

Attaching the BT-DUAL
Attach the BT-DUAL to the Bluetooth ADAPTOR jack.
1. Power down the amp and unplug the power cord from the AC outlet.
2. Remove the cover and screw from the Bluetooth ADAPTOR jack on the rear panel.

Listening to sound via wireless connection with a mobile device
Bluetooth® audio functionality
You can play back music or music video content on a mobile device with Bluetooth audio functionality, and listen to the content through the amp speaker or through an external speaker that’s connected to the amp.

3. Attach the BT-DUAL and fasten the screw that you removed in step 2 in place.
NOTE ¹ Be sure to use only the screw that was originally mounted on the
Bluetooth ADAPTOR jack. If you use a different screw, the unit may malfunction. ¹ Do not touch the circuitry or the jacks. ¹ After you have attached the adaptor, check again to make sure it’s properly installed.

Registering a mobile device (pairing)
“Pairing” involves registering the mobile device that you want to use with the KATANA amp (making the two devices recognize each other). This shows how to configure the settings so that music data saved on your mobile device can be played wirelessly from the KATANA amp.
MEMO The following explanation is only one example. For details, refer to the owner’s manual of your mobile device.
1. Turn on your amp.
2. Place the mobile device that you want to connect close to the amp.
3. Hold down the pairing button on the BT-DUAL until the Bluetooth indicator blinks rapidly.

4. Turn on the Bluetooth function of the mobile device.

MEMO This explanation uses the iPhone as an example. For details, refer to the owner’s manual of your mobile device.
5. Tap “KATANA 3 Audio”, shown on the Bluetooth device screen of your mobile device.
This pairs the BT-DUAL with your mobile device. When pairing succeeds, “KATANA 3 Audio” is added to the list of “Paired Devices” on your mobile device. * If you don’t complete the pairing within a certain time, the Bluetooth indicator goes dark and the unit exits pairing standby mode.

If you want to disconnect the Bluetooth connection between the BT-DUAL and your mobile device, disable Bluetooth functionality.
1. Press the pairing button on the BT-DUAL.
The Bluetooth indicator goes dark.

MEMO
¹ If you were unable to connect using the steps above, tap “KATANA 3 Audio”, displayed in the Bluetooth device screen of the mobile device.
¹ To disconnect, press the pairing button on the BT-DUAL to make the Bluetooth indicator go dark, or turn off the mobile device’s Bluetooth function.

Controlling the amp from an app on your mobile device
You can use the BOSS TONE STUDIO for KATANA Gen3 dedicated app to edit effects and save this unit’s settings. For details on BOSS TONE STUDIO for KATANA Gen3, refer to the BOSS website. https://www.boss.info/

Adjusting the volume
1. Adjust the volume on the mobile device.

The [MASTER VOLUME] knob controls Bluetooth audio, the audio of devices connected to the USB port, and the volume of audio from mobile devices connected to the AUX IN jack. When you turn the [MASTER VOLUME] knob, this controls both the volume of Bluetooth audio and the volume of the devices connected to each jack.
