A2BP pro MARK II

The renowned A2BP pro, celebrated in various audio landscapes, has transformed into the premium, professional-grade A2BP pro MARK II—a dual-channel bass preamp crafted for superior sound manipulation. Like its predecessor, it boasts a head amp that powers vacuum tubes at high voltage. However, the tone control has seen enhancements. CH-A preserves the original tone control, while CH-B now features the same robust and dynamic tone circuit as the A1BP pro MARK II. ※ Both channels offer a flat response with tone controls set to the center position, just like the earlier model. In addition, the classic toggle-style MUTE switch has been upgraded to a footswitch for convenient hands-free use. A new BALANCE VOL control has also been introduced, allowing for independent volume adjustments from the BALANCE OUT, separate from the MASTER control. Moreover, the AUX IN input has transitioned from RCA connectors to a 3.5mm jack for enhanced flexibility.
