SAFETY PRECAUTIONS
In this manual, symbols are used to highlight warnings and cautions for you to read so that accidents can be prevented. The meanings of these symbols are as follows:
This symbol indicates explanations about extremely dangerous matters. If users ignore this symbol and Warning handle the device the wrong way, serious injury or death could result. If users ignore this symbol and handle the device the wrong way, bodily injury and damage to the equipment could result.
Warning
· Never place objects filled with liquids, such as vases, on the A2. 1u since this can cause electric shock. [. . . ] At the same time, you can also connect the [OUTPUT/PHONES] jack to a guitar amplifier for monitoring.
Mixer
[BALANCED OUT] connector
In this condition, the sound of a guitar connected to the [INPUT] jack of the A2. 1u can be processed with the effects of the A2. 1u and then be recorded on the audio tracks of a DAW (Digital Audio Workstation) software application on the computer. At the same time, the [OUTPUT/PHONES] jack of the A2. 1u carries the playback sound from the audio tracks of the DAW application, mixed with the guitar sound processed by the effects of the A2. 1u (see illustration below). For details on recording and playback, refer to the documentation of the DAW application.

Other Functions
The [PRE/POST] switch lets you control the position where the signal supplied at the [BALANCED OUT] connector is branched off. To use the signal after effect processing, select the "POST" position (switch engaged). To use the signal before effect processing, select the "PRE" position (switch disengaged).
foot switch. The indication "Hi-GAin" scrolls on the display, and input gain will be set to a higher value. NOTE
The input gain setting is not stored in memory and will be canceled when the unit is turned off. Perform the above procedure every time at power-on, as needed.
Restoring Factory Defaults
HINT
When the [PRE/POST] switch is set to "POST", the signal at the [BALANCED OUT] connector reflects the setting of the AMP SELECT parameter ( p. If the [OUTPUT/PHONES] jack is not connected directly to a guitar amplifier and only the [BALANCED OUT] connector is used, setting the AMP SELECT parameter to "oF" may be preferable.
In the factory default condition, the patches of the user area (A0 d9) contain the same settings as the patches of the preset area (00 39). Even after overwriting the user patches, their original content can be restored in a single operation ("All Initialize" function).
In certain configurations, a ground loop (electrical signal loop created because devices within the same system are connected to a separate ground) may occur, leading to noise problems (audible hum). HINT
The [GROUND] switch controls the [BALANCED OUT] connector ground connection. In the "LIFT" position (switch engaged), the ground pin of the [BALANCED OUT] connector is uncoupled from the signal path. This can be effective in eliminating or reducing hum noise caused by a ground loop.

Turn the A2. 1u on while holding down the [STORE] key. The indication "AL" appears on the display.

To carry out the All Initialize function, press the [STORE] key once more. All patch settings are returned to the factory default condition, and the unit switches to play mode. To cancel All Initialize, press the RHYTHM [R/P] key instead of the [STORE] key. NOTE
When you carry out All Initialize, any newly created patches that were stored in the user area will be deleted (overwritten). Perform this operation with care to prevent losing any patches that you want to keep.
2.
Starting the A2. 1u in HIGAIN mode
When using a magnetic pickup, an electric guitar with a single-coil pickup, or any other guitar with low output level, the input gain of the A2. 1u may have to be increased by starting it in HI-GAIN mode, as explained below.
To start the A2. 1u in HI-GAIN mode
