IMPORTANT NOTES
Power Supply
- Do not connect this unit to same electrical outlet that is being used by an electrical appliance that is controlled by an inverter or a motor (such as a refrigerator, washing machine, microwave oven, or air conditioner). Depending on the way in which the electrical appliance is used, power supply noise may cause this unit to malfunction or may produce audible noise. If it is not practical to use a separate electrical outlet, connect a power supply noise filter between this unit and the electrical outlet.
Placement
• Using the unit near power amplifiers (or other equipment containing large power transformers) may induce hum. To alleviate the problem, change the orientation of this unit; or move it farther away from the source of interference.
- This unit may interfere with radio and television reception. Do not use this unit in the vicinity of such receivers.
- Noise may be produced if wireless communications devices, such as cell phones, are operated in the vicinity of this unit. Such noise could occur when receiving or initiating a call, or while conversing. Should you experience such problems, you should relocate such wireless devices so they are at a greater distance from this unit, or switch them off.
- When moved from one location to another where the temperature and/or humidity is very different, water droplets (condensation) may form inside the unit. Damage or malfunction may result if you attempt to use the unit in this condition. Therefore, before using the unit, you must allow it to stand for several hours, until the condensation has completely evaporated.
- Depending on the material and temperature of the surface on which you place the unit, its rubber feet may discolor or mar the surface.
- Do not place containers or anything else containing liquid on top of this unit. Also, whenever any liquid has been spilled on the surface of this unit, be sure to promptly wipe it away using a soft, dry cloth.
Route all power cords and cables in such a way as to prevent them from getting entangled
Injury could result if someone were to trip on a cable and cause the unit to fall or topple.
Avoid climbing on top of the unit, or placing heavy objects on it
Otherwise, you risk injury as the result of the unit toppling over or dropping down.
Never connect/disconnect a power plug if your hands are wet
Otherwise, you could receive an electric shock.
Disconnect all cords/cables before moving the unit
Before moving the unit, disconnect the power plug from the outlet, and pull out all cords from external devices.
Maintenance
- Never use benzine, thinners, alcohol or solvents of any kind, to avoid the possibility of discoloration and/or deformation.
Repairs and Data
- Before sending the unit away for repairs, be sure to make a backup of the data stored within it; or you may prefer to write down the needed information. Although we will do our utmost to preserve the data stored in your unit when we carry out repairs, in some cases, such as when the memory section is physically damaged, restoration of the stored content may be impossible. Roland assumes no liability concerning the restoration of any stored content that has been lost.
Additional Precautions
- Any data stored within the unit can be lost as the result of equipment failure, incorrect operation, etc. To protect yourself against the irretrievable loss of data, try to make a habit of creating regular backups of the data you've stored in the unit.
- Roland assumes no liability concerning the restoration of any stored content that has been lost.
- Use a reasonable amount of care when using the unit's buttons, sliders, or other controls; and when using its jacks and connectors. Rough handling can lead to malfunctions.
- When disconnecting all cables, grasp the connector itself—never pull on the cable. This way you will avoid causing shorts, or damage to the cable's internal elements.
- A small amount of heat will radiate from the unit during normal operation.
- To avoid disturbing others nearby, try to keep the unit's volume at reasonable levels.
- Use only the specified expression pedal. By connecting any other expression pedals, you risk causing malfunction and/or damage to the unit.
- Do not use connection cables that contain a built-in resistor.
CAUTION
Before cleaning the unit, disconnect the power plug from the outlet
If the power plug is not removed from the outlet, you risk receiving an electric shock.
Whenever there is a threat of lightning, disconnect the power plug from the outlet
If the power plug is not removed from the outlet, you risk causing malfunction or receiving an electric shock.

Switch Explanation
TIP Switches between CH1 and CH2.
RING Switches between BANK A and BANK B.
* The KATANA Mk II is compatible with latch-type footswitches (FS-6, FS-7, FS-5L). If you're using an FS-6 or FS-7, set the mode of A and B to FS-5L (LATCH). Momentary-type footswitches (e.g., FS-5U) cannot be used.
Connecting the GA-FC 100, 100/212, HEAD only
Connect a stereo cable to the GA-FC jack.
* Always use a stereo cable.

Using the expression pedals
If you connect an expression pedal (sold separately: Roland EV-5, BOSS EV-30, BOSS FV-500L, BOSS FV-500H), you can use the pedal to vary the volume or control an effect such as WAH.
Expression Pedal
| Jack Explanation | |
| VOLUME Adjusts the volume. | |
| EXP You can control an effect such as WAH. | |
* You can use dedicated software (p. 9) to assign a function of your choice to an expression pedal connected to the VOLUME or EXP jack.
Setting MINIMUM VOLUME of an expression pedal
With the [MINIMUM VOLUME] knob of an expression pedal, you can set the value for when the pedal is lifted up all the way (lowest value).
* Use only the specified expression pedal. By connecting any other expression pedals, you risk causing malfunction and/or damage to the unit.
Using the footswitches
If a footswitch (sold separately: FS-6, FS-7, or FS-5U) is connected, you can use it to switch between the TONE SETTING's BANK A/B, or to set the delay time (TAP).
| Jack Explanation | |
| FS1 Switches the TONE SETTING's BANK A/B. | |
| FS2 | Sets the delay time. When you press this button two or more times, the delay time is set to the interval between presses. |
* You can use dedicated software (p. 9) to assign a function of your choice to a footswitch connected to the FS1 or FS2 jack.
Using the GA-FC to switch the BANK
With one of the channels [CH1]–[CH4] selected, hold down the [PANEL] switch for approximately one second.
The selected [CH1]–[CH4] switch blinks, and the bank switches between BANK A and BANK B. When BANK B is selected, the [PANEL] button blinks slowly.
* You can't switch banks while PANEL is selected.
Turning the Power On/Off
* Once everything is properly connected (p. 4–p. 6), 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.

-
Turn on the power of the devices connected to the LINE OUT jack and PHONES/REC OUT jack.
-
Adjust the volume levels for the devices.
Before switching off the power, lower the volume on each of the devices in your system and then TURN OFF the devices in the reverse order to which they were switched on.
* If you need to turn off the power completely, first turn off the unit, then unplug the power cord from the power outlet. Refer to "To completely turn off power to the unit, pull out the plug from the outlet" (p. 2).
Restoring the Factory Settings
Here's how the settings stored in the KATANA Mk II can be returned to their factory-set condition (factory reset).
- While holding down the [PANEL] button, turn the power on.
Each of the EFFECTS buttons continues blinking consecutively from the left. When the blinking stops, all of the KATANA Mk II'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.
On the KATANA Mk II amp, you can use five types of effect simultaneously.
