   Connect the included AC adapter to this jack.
   The AC adapter is designed specifically for the VX50 AG. Do not use any other adapter, otherwise a malfunction may occur.

2. Cord hook
   Wrap the AC adapter cord around this hook to prevent the AC adapter from being accidentally disconnected.

3. LINE OUT jack
   Connect your PA system to this jack.

4. INSTRUMENT jack
   Connect your guitar to this jack.

5. PHASE switch
   Use this switch to reverse the phase of the input to the INSTRUMENT jack.
   This counteracts low-frequency range phase interference with the input from the MIC jack and suppresses howling in the low-frequency range.

6. INSTRUMENT VOLUME knob, CLIP indicator
   Use this knob to adjust the volume level of the guitar. The CLIP indicator lights up if the volume level of the connected musical instrument is too high. Clipping could  distort the sound and reduce the sound fidelity.
   To avoid clipping, use the INSTRUMENT VOLUME knob to adjust the volume level.

7. INSTRUMENT equalizer Use this knob to adjust the sound of the INSTRUMENT channel.
   BASS knob

   TREBLE knob
   Use this knob to adjust the sound in the high-frequency range. As each knob is turned to the right, the range corresponding to the knob will be  emphasized. However, if a range is overemphasized, feedback (howling) will be more likely to occur.

8. INSTRUMENT EFFECTS knob Use this knob to adjust the depth of the chorus, reverb or chorus+reverb effect for the instrument connected to the INSTRUMENT jack. Use this knob to select the effect type  and adjust the effect parameters. When this knob is fully turned to the left, all effects are off.

11. MIC VOLUME knob, CLIP indicator
    Use this knob to adjust the volume level of the microphone connected to the MIC jack.
    This indicator lights up if the volume level of the connected microphone is too high. Clipping could distort the sound and reduce the sound fidelity.
    To avoid clipping, use the MIC VOLUME knob to adjust the volume level.

12. MIC equalizer
    Use this knob to adjust the sound of the MIC channel.
    BASS knob
    Use this knob to adjust the sound in the low-frequency range.
    TREBLE knob
    Use this knob to adjust the sound in the high-frequency range.
    As each knob is turned to the right, the range corresponding to the knob will be emphasized. However, if a range is overemphasized, feedback (howling) will be more  likely to occur.

13. MIC REVERB knob
    Use this knob to adjust the depth of the reverb effect for the input connected to the MIC jack.

14. MASTER knob
    Use this knob to adjust the overall volume level of the VX50 AG.

2. Connect the included AC adapter and power cord.

3. Connect the DC plug of the AC adapter to the DC 19V jack on the rear panel of the amp, and then connect the plug of the power cord to an AC outlet.

4. Secure the cord with the cord hook on the amp to prevent the DC plug from being disconnected.

5. If a guitar will be used, connect the cable from the guitar to the INSTRUMENT jack.
   If a microphone will be used, connect it to the MIC jack. If a condenser microphone that requires phantom power will be used, set the PHANTOM switch to ON.
   If an audio player will be used, connect it to the AUX IN jack.

6. Hold down the button until the power indicator lights up and the amp turns on.

7. Slowly raise the MASTER knob to adjust the overall volume.

Auto power-off function

The amp has an auto power-off function. With this function, the amp automatically turns off if there is no operation or input for approximately 4 hours. When the amp turns off, operating a knob or switch does not turn it back on. After the amp is turns off, turn it on again.
The auto power-off function cannot be disabled.
When there is input only to the AUX IN jack, when the input level to the INSTRUMENT jack or MIC jack is extremely low or changes insignificantly, or when you turn down the INSTRUMENT VOLUME knob or the MIC VOLUME knob the auto power-off function may be activated.
Depending on the settings and environment, the amp may interpret noise as input, even if there is no performance, and the auto power-off function may not be activated.
