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 amplifire on set the [MASTER] volume control on the AGA70/150 to minimum. 2. Connect the supplied power cord to the AC power connector on the rear panel, then insert the plug on the other end of the power cord into an appropriate AC outlet. 3. If you are playing an acoustic musical instrument, such as a guitar with a pick-up, connect it to the [GUITAR] connector. If you are using a microphone, connect it to the [MIC] connector. 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. 5. Turn up the [MASTER] volume control slowly to adjust the volume level.

NORMAL CH The Normal channel features a solid sound that will delive the natural acoustics of your instrument. 2. 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. 3. [GUITAR] connector Plug in your guitar (or other acoustic musical instrument featuring a pick-up) using a high-quality shielded cable. NOTE:If you plug in your instrument to this connector, the [MIC] connector on the same channel will be disabled. 4. [GAIN] switch Set the input gain to “LOW” or “HIGH” depending on the volume level of the musical instrument connected to the [GUITAR] or [MIC] connector. 5. [MIC] connector Connect your microphone to this balanced XLR connector. 6. [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. NOTE:If the microphone does not require phantom power, turn the [PHANTOM] switch off. NOTE:Before you turn the [PHANTOM] switch on or off, be sure to set the [MASTER] volume control to minimum. Also, before you connect a microphone to the [MIC] connector, be sure to turn the [PHANTOM] switch off. 7. [VOLUME] control This control knob enables you to adjust the volume level of the musical instrument connected to the [GUITAR] or [MIC] connector. Use this control on each channel to adjust the level and balance between the Normal and Tube Pre channels. 8. 8. 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] control to adjust the volume level. 9. [BASS] control 10. [MIDDLE] control 11. [TREBLE] control These controls enable you to adjust the tone in the low, mid and high ranges respectively. NOTE:Turn each control clockwise to enhance the corresponding range.

Set the control knob so that the amount of feedback will be minimum. Turning the control knob clockwise will move the cut point to a higher frequency range. Turning the control knob counter-clockwise all the way will turn off the anti-feedback effect. Turn this control off if you hear no feedback. 18.
