Setting Up Your Amplifier
This section explains how to set up your amplifier.
NOTE:This manual includes safety precautions and an explanation of the parts and functions of the amplifier. Please read this manual throughly.
1.Before turning the amplifier on, set the MASTER volume knob on the AGA30 a minimal level.
2.Connect the supplied power cable to the AC power connector on the rear panel, then insert the plug on the other end of the power cable into an appropriate AC outlet.
NOTE:Use only the power cable that is included with the AGA30. Using another power cableÅ@may cause malfunctions.
3.Connect your guitar or microphone to the AGA30. If necessary, connect an external device to the AUX IN jack or the TUNER/DIRECT OUT jack.
NOTE:If the microphone requires phantom power, turn the PHANTOM switch on. If the microphone does not require phantom power, turn the PHANTOM switch off.
4.Turn on the power to the amplifier by setting the POWER switch to On.

1.TUBE PRE (VALVE) CH
The Tube Pre channel features a Vox signature warm sound due to a tube preamp that uses a 12AU7 valve.
NOTE:It may take several seconds for the tube to warm up after the power is turned on. During this time, you may not hear any sound, but this is not a malfunction.
2.NORMAL CH
The Normal channelprovides a solid sound that will faithfully deliver the natural tone of your instrument.
6
3.GUITAR/MIC jack
This input jack combines a 1/4" phone jack for guitar with an XLR jack for mic.
NOTE: The volume might be insufficient if you connect a mic to the 1/4" phone jack.
4.PHANTOM switch
Turn this switch on when you connect a condenser microphone that requires phantom power. When the phantom power is being supplied, the indicator above the switch lights up. Phantom power is supplied only to the XLR jack.
NOTE:You must turn the PHANTOM switch off if you've connected a mic that does not require phantom power.
NOTE:Before you turn the PHANTOM switch on or off, be sure to set the MASTER volume control down. Also, before you connect a microphone to the GUITAR/MIC jack, be sure to turn the PHANTOM switch off.
5.GUITAR jack
Plug in your guitar using a high-quality shielded cable.
6.GAIN switch
Set the input gain to “LOW” or “HIGH” depending on the volume level of the musical instrument that’s connected to the GUITAR or GUITAR/MIC jack.
7.VOLUME knob
This control knob enables you to adjust the volume level of the musical instrument that’s connected to the GUITAR/MIC or GUITAR jack. Use this control on each channel to adjust the level and balance between the Tube Pre and Normal channels.

AGA30 Owner’s manual
8.CLIP indicator
This 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 GAIN switch and VOLUME knob to adjust the volume level.
9.BASS knob
This knob adjusts the tone of the low-frequency region.
NOTE:Turning the knob toward the right will boost the low-frequency region, but excessive boosting could cause acoustic feedback (a whine or howl.)
10.TREBLE knob
This knob adjusts the tone of the high-frequency region.
NOTE:Turning the knob toward the right will boost the high-frequency region, but excessive boosting could cause acoustic feedback (a whine or howl.)
11.EFFECTS knob
This knob adjusts the depth of the reverb or chorus effect.
12.ANTI-FEEDBACK knob
This knob enables you to reduce the amount of feedback that is caused when the output of the amplifier is picked up via a guitar or microphone.
Set the control knob so that the amount of feedback will be minimal.
Turning the control knob clockwise will move the cut point to a higher frequency range. Turning the control knob all the way counter-clockwise will turn off the anti-feedback effect.
Turn this control off if you hear no feedback.
8
13.MASTER volume knob
This knob enables you to adjust the overall volume level of the Normal and Tube Pre channels.
NOTE:The MASTER volume control does not affect the signal level at the TUNER/DIRECT OUT or AUX IN jacks.
14.ALL MUTE switch
Set this switch to On to mute the sound output from the amplifier.
NOTE:This switch does not mute the sound output from the TUNER/DIRECT OUT jack.
HINT: Connect an optional VFS2 dual foot switch to the amplifier to control All Mute on and off with your foot.
15.POWER indicator
The indicator lights up when the power to the unit is turned on. The POWER switch is located on the rear panel.

1.POWER switch
When you turn this power switch on, the POWER indicator on the front panel will light up.
2.AC power connector
Connect the supplied power cable here.
3.FOOT SW jack
Connect an optional VFS2 dual foot switch here. For more information on using the foot switch, please refer to “Controlling the Amplifier with VFS2 Dual Foot Switch” on page 12.
NOTE:You must connect or disconnect the foot switch while the power is off. Malfunctions or damage may occur if you connect or disconnect the foot switch while the power is on.
4.TUNER/DIRECT OUT jack
Connect your tuner or PA system to this jack. It will output the unmodified sound of the instrument that's connected to the GUITAR/MIC jack or GUITAR jack.
10
NOTE:The Direct Out signal is not affected by either the ALL MUTE switch or the MASTER volume control.
HINT: When a tuner is connected, you can turn on the ALL MUTE switch and tune without outputting any sound from the amp.
HINT: The TUNER/DIRECT OUT jack is positioned just before the VOLUME control in the signal flow. Therefore, it will output a signal that has not passed through the tube, tone control, reverb and chorus effects, or anti-feedback control. (Please refer to the block diagram on page 13.)
5.AUX IN jack
You can connect your audio player or any other audio source to this stereo mini-phone jack.
NOTE:The AGA30 features a monaural output. When a stereo signal is input to the AUX IN jack, it will be converted to monaural inside the amplifier.

AGA30 Owner’s manual
Controlling the Amplifier with VFS2 Dual Foot Switch
Using an optional VFS2 dual foot switch connected to the FOOT SW jack on the rear panel of the AGA30 enables you to use your foot to turn the Effect Bypass on or off (disabling or enabling the reverb and chorus effects), and switch All Mute on and off.
NOTE:You must connect or disconnect the foot switch while the power is off. Malfunctions or damage may occur if you connect or disconnect the foot switch while the power is on.
Switching Effect Bypass on and off (Switch 1)
If you use switch 1 of the VFS2 to turn effect bypass on, all effects will be bypassed regardless of how the front panel EFFECTS knob is set. Effect bypass will be cleared when you press switch 1 once again or use the front panel EFFECTS knob.
Switching All Mute on and off (Switch 2)
The VFS2 Switch 2 works in the same way as the ALL MUTE switch on the front panel (see “ALL MUTE switch” on page 9). Pressing the Switch 2 will switch All Mute on or off.
