A Word from Marco De Virgiliis
MARK VISION
Thank you for choosing DV Mark!
We are very excited to have you join us for an exciting new chapter in the history of guitar amplification. In less than 10 years, we have succeeded in making
Markbass the world’s leading bass amp brand, using technology to better serve the needs of bassists: great tone, reliability, versatility/flexibility, and light weight.
Now it’s time for guitarists to have their turn!
The classic tones guitarists have come to know and love over the last few decades are worthy of great respect. We have designed our amps with a great reverence
for these sounds. We’re not trying to start a revolution in guitar tone… because guitarists don’t want or need that.
However—there are some important areas where the classic amplifiers can be greatly improved upon, to better suit the needs of guitarists:
The first is reliability—and we are very proud of the high quality standard that we’re able to offer thanks to our 100% Made in Italy production, state-of the-art
testing and quality control facilities, top-quality components, and innovative technology that makes it easy to monitor the condition of your amp and its tubes. You
need to be able to always trust your amp… and we understand that!
The second is flexibility. One example of this is DV Mark’s patent pending Continuous Power Control feature (included on our 40W heads and combos), which
allows you to adjust the power incrementally, setting the power at anywhere between 1 and 40W. This means you can get the tone you want at the volume you need;
so you can use the same amp for everything, from larger gigs, to smaller gigs, right down to bedroom practicing—and never sacrifice your tone!
The third is light weight. Many of you have seen your bass players easily loading in and out of gigs with their lightweight Markbass gear, while you struggle
with a heavy 2x12 combo or 4x12 cabinet. It’s time you enjoyed the same benefits of lightweight gear! Especially if you play a lot, the weight of your gear is a real
factor. Once you learn that DV Mark allows you to get killer tone at a fraction of the weight… there’s no going back.
We hope you will enjoy your new guitar amp, and we invite you to contact us any time with your comments and questions, at [email protected]
Thanks again, and good music!

FRONT PANEL
1) INPUT Connect your guitar to this input using a standard ¼” shielded instrument cable.
2) 0/-6dB SWITCH This switch pads the input (1) from 0 dB to -6 dB to compensate for higher-output sources, such as guitars with highoutput pickups or active electronics.
3) GAIN This knob sets the gain level (on each channel), and is the preamp’s most powerful control. It not only determines the amount of
drive or saturation (for getting clean, crunch or overdriven sounds, or anywhere in between), but also plays an important role in tone shaping.
4) MASTER This control is the master feed from the end of the preamp channel to the tube power stage. Each channel features its own
MASTER control, allowing you to perfectly balance the relative volumes of the three channels, which can have very different sound styles and
gain/drive levels. On each, the master control allows you to obtain a wide range of sounds/colours in relation to the gain setting—for example,
very low-gain sounds at high volumes, or high-gain sounds at low volumes.
5) PRESENCE The PRESENCE knob (featured only on channel one) controls high frequencies, above those controlled by the High knob. It’s
an effective and useful part of the channel’s tone controls. Turning up the Presence knob gets you a crisp and sparkling clean sound in channel
1.
6) BASS This knob controls the amount of low frequencies in your sound. When you’re starting to explore sounds on the amp, avoid boosting
the lows too much as this can reduce your attack and muddy your sound. And as the gain is turned up, it’s a good idea to lower the bass
control somewhat for a more balanced sound (starting with the bass setting at around 12 o’clock).
7) MIDDLE The Middle control regulates the midrange frequencies and is an important part of your tone shaping. The frequency range it
boosts or cuts has a big effect on the character of your sound. For a more scoopy tone, lower the mids. Turn the knob up for more focused
attack and better pitch definition.
8) HIGH The High knob controls the amount of high frequencies in your sound. It can produce unwanted noise (hiss) or pickup feedback when
really cranked, so it’s best to avoid extreme settings, especially on channels 2 and 3, due to their higher gain.
9) SOLO This 6 dB boost is activated by either a footswitch or the Smart Controller, and is optimized for notching up your volume for solos
during live performance.
10) CONTINUOUS POWER CONTROL (CPC) This patent pending feature allows you to control the actual power of the amp, from full power
40W (class A/B) gradually down to 1W (class A). This allows users to get the tone they want at any volume for any musical situation.

11) STANDBY Before powering on, make sure this switch is in standby position. When you turn on the power, the microcontroller waits for
the tubes to heat up before turning on the plate voltage. The “power on” LED will flash for 30 seconds before the amp is ready. When the LED
stops blinking, flip the standby switch to the ON position. Between sets or whenever you’re on a break from playing, put the amp in standby
position (down).
12) POWER This switch delivers AC power to the amp. Make sure the unit is grounded; all three terminals of the AC power plug must be
connected to avoid any injury to the user or damage to the unit. DV Mark amps and combos are manufactured to be used in the country where
they have been sold, and are factory preset to that country’s voltage. So make sure you’re sending the correct voltage to your amp before you
connect it to AC power. Follow the procedure described in the STANDBY section above (12) before powering up your amp.

13) SPEAKER OUTS The amp offers the following speaker output jacks for connecting the head to a speaker cabinet or cabinets: one 4 ohm,
one 8 ohm and one 16 ohm jack. Verify the impedance of your speaker/s prior to connection, and make sure you are using the correct speaker
output/s.
14) PRE OUT/AMP IN The DV 403 CPC features an effects loop for use with outboard effect processors or pedals. Connect the PRE OUT
jack to the input of your processor or pedal chain, and connect your effects output to the AMP IN jack.
15) LOOP ASSIGN The Loop Assign knob allows you to assign the effects loop to whichever channel you want, to all the channels, or to none
of the channels. You can make this selection in manual mode (using this knob) or by using the SMART CONTROLLER. When you connect the
Smart Controller to its dedicated input (17), this rotary knob must be set to ENABLE. In this position, the channel switching and solo boost
footswitches are inactive, and all the settings will be managed by the Controller. The Controller automatically recalls the settings you last used
before the amp was powered off. For example, if you assign your effects to channel 2 using the controller, and turn off the amp, the next time
you turn on the amp and plug in the Controller, the effects will still be assigned to channel 2.
16) CH SELECT This switch allows you to switch channels manually when the Smart Controller is not connected to the amp. Pressing this
button advances to the next channel in sequence (1-2-3-1-2-3 etc), and the channel that is active is identified by the indicator LEDs on the
amp’s front panel.
17) CONTROLLER This stereo input jack is exclusively for the Smart Controller. Other footswitches will not work connected to this input.
18) MIDI IN This input port receives incoming MIDI information from an external MIDI device. The MIDI receive address is set to “0” by
default. If your external MIDI device transmits on another address, you can change the default address by holding the CH SELECT (16) switch
for about 10 seconds—the unit then enters “Learn Mode” and you can set the new address by pressing any switch on your MIDI pedalboard
to initialize the connection to the amp.
19) MIDI OUT/THROUGH This output jack sends out MIDI messages identical to those coming in through the MIDI IN.
20) BIAS Switch (low/high) Triple 6 can operate in either Low Bias mode or High Bias mode. When this button is pressed in, the power
tubes work in High Bias mode; when the button is out, they work in Low Bias mode. In Low Bias mode, the tubes use less power and less ‘tube
life’ is taken out of them. High Bias mode gives top quality and power, and higher-fidelity sound—but the power consumption and dissipation
of the tubes increases. In either mode, unlike other tube amplifiers, the Triple 6 is able to greatly prolong the life of its tubes by keeping them
