SAFETY INSTRUCTIONS 1.
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 CH1 (Hi Z 1MΩ) Connect your guitar to this input using a standard ¼” shielded instrument cable. This input is suitable for instruments that have normal-output pickups and passive electronics. 2) INPUT CH2 (Low Z -6dB) This input is padded by 6 dB to compensate for higher output sources, and is suitable for use with guitars that have high-output pickups or active electronics. 3) NORMAL/BRIGHT This switch boosts upper-treble frequencies, adding brightness to your sound.
8) MASTER (CH2) This control is the master feed from the end of the preamp channel to the tube power stage. It 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. 9) BASS This knob controls the amount of low frequencies in your sound.
FRONT PANEL 15) CONTINUOUS POWER CONTROL (CPC) This patent pending feature allows you to change the actual power of the amp, from full power 40W (class A/B) gradually down to 1W (class A) in Pentode mode—or 15W (class A/B) to 0.5W (class A) in Triode mode. This allows users to get the tone they want at any volume for any musical situation. 16) STANDBY Before powering on, make sure this switch is in standby position.

Verify the impedance of your speaker cabinet to make sure you connect it to the correct output. 21) TUBE MODE This switch allows you to switch between the two tube operating modes, Pentode and Triode.
