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.
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.
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.
REAR PANEL 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.
