DBX BX-3 mkII

This vintage (1990), 1 owner (me) multi-channel amplifier is a rare find in such good condition … meters, switches, lights and LEDs are all fully functional. Top cover, dark cherry side panels are in very good shape.  No obvious cosmetic flaws.

The unit was recently inspected by an authorized DBX Pro service technician and found to be fully functional and up to spec. Only recommendation was routine cleaning of pots and switches … which was performed. Otherwise, it got a clean bill of health.  

The BX-3 Mk II incorporates four independent power amps allowing it to be configured via a switch on the back panel to function as a 2 Channel Stereo, 3-Channel (L/R + Center or Sub) OR a 4-Channel amp delivering 300W RMS x2 . . . 125W RMS x2 + 300W RMS x1 or 125W x 4 channels respectively at 20-20kHz with no more than 0.01% total harmonic distortion.

It can drive up to 4 Pairs of speakers simultaneously and can be bridged for up to 800W RMS per channel at 4 Ohms. The front panel contains two large backlit VU meters for tracking peak power output.

The BX-3 Mk II has switchable voltage capability for use worldwide (120 / 220 / 240) as well as a Speaker Impedance Selector for driving 2-16 ohm speakers. It has a built-in cooling fan. If internal temps ever reach over 70 degrees C / 158 F the fan will turn on automatically. It very rarely came on in my experience and was very quiet the few times it did. 

The BX-3 MkII is a versatile, solidly built (46.4 lbs!) powerhouse of an amp. It’s fast, detailed and capable of throwing a wide sound stage. Read more about its many functions and features on the attached excerpts from the owner’s manual.

Will be double boxed and well protected for shipment. Overall dimensions and gross weight to be determined.
