Introduction Welcome aboard! Thanks for choosing the VOX DA10/DA20. To ensure a long and trouble-free relationship with your new amp, please read this manual carefully, use the amp as directed and keep the manual for future reference. Main features • • • • • 4 The compact DA10/DA20 features ten or twenty watts (10W/20W) producing stellar tones inherited from the VOX Valvetronix series (AD15VT, AD30VT, AD50VT, AD100VT). The amplifier can be powered by six C alkaline batteries.
Setup Installing Batteries Please refer to the illustrations in the section entitled “The Guitarist’s Guided Panel Tour” (page 7). 1. Turn the MASTER volume on the amp all the way down. 2. Insert the batteries as shown on page 5. Alternatively, plug the supplied power cord into the power input on the rear panel, then plug the power cord into a wall outlet. Remove the battery compartment cover located on the bottom of the unit by pulling the ribbon. Insert six C alkaline batteries as shown in the figure.
Replacing the batteries Replace the batteries when the indicator above the STANDBY switch becomes dim. NOTE: If the battery power is low, noise may be heard. NOTE: Depleted batteries must be removed from the DA10/ DA20 immediately. If you leave them in, malfunctions such as battery leakage may occur. You should also remove the batteries if you will not be using the DA10/ DA20 for an extended time.

Styles and effects In this section we’re going to talk about the eleven styles and effects. STYLES You know that there is a plethora of great sounding amps out there, and that the quest for the ultimate sound can be endless. After countless hours of soul searching, earnest discussions (not to mention the occasional friendly argument!), calls to tone-wise friends (some professional players, some not ...
CRUNCH 1 This organic sounding style is dynamically rich and warm, yet biting and distinct! Rolling back your guitar’s volume results in a unique and highly usable clean sound. CRUNCH 2 This style has a fat, roaring sound with a distinctive, cranium-crushing crunch. Rolling back your guitar’s volume produces a bright, clean sound that’s perfect for chord work and will cut through any mix.
Effects The DA10/DA20 provides eleven of the most popular effects (some effects actually combine two effects). You can adjust the SPEED parameter of modulation effects or the TIME parameter of delay/reverb effects simply by pressing the TAP switch twice. In addition to using the EDIT 1 knob to adjust the most important parameters, you can make more detailed adjustments by holding down the TAP button or BYPASS button while turning the EDIT 1 knob.
AUTO WAH PHASER This models an auto-wah; a device that creates an automatic “wah” effect that varies with your picking dynamics (i.e., how hard or soft you hit the strings). EDIT 1 “SENS” EDIT 2 “ATTACK” EDIT 3 “POLARITY” Adjusts the sensitivity of the effect in response to the volume of your guitar. Adjusts the response speed of the auto wah. Adjusts the direction in which the effect operates. COMP EDIT 2 “ATTACK” TAP Sets the modulation speed in a range of 0.1...10 [Hz].
TREMOLO TAP This effect is based on the highly acclaimed tremolo circuit found in some guitar amps. TAP “SPEED” EDIT 2 “SPEED” EDIT 3 “DEPTH” Sets the tremolo speed in a range of 2.5...10 [Hz]. This lets you use the knob to make fine adjustments to the parameter. Adjusts the tremolo depth. ROTARY This models a rotary speaker. TAP “SPEED” EDIT 2 “SPEED” EDIT 3 “SENS” Sets the rotational speed of the speaker in a range of 0.8...10 [Hz].
Troubleshooting 1. The amp isn’t powering up when the STANDBY switch is ON. • Have you installed batteries? Is the polarity correct? Or, is the power cord connected to the rear panel of the amp correctly? Is the power cord plugged into an AC outlet? Is the AC outlet switched on and working? Is the power cord damaged? 4. There’s no sound heard from the LINE/PHONE jack when you use it. • • Check that the top panel MASTER volume isn’t turned all the way down. Make sure sound is coming from the amp. 2.
