The JBL 306P MkII is the 6.5-inch sibling in JBL's 3 Series MkII line, adding low-end reach over the 305P while sharing its connectivity. As an active monitor each cabinet powers itself from a line-level feed, with two balanced rear inputs, a 3-pin XLR and a 1/4-inch TRS jack, plus a +4 dBu / -10 dBV sensitivity switch for pro or consumer sources. Only one input should be connected at a time. There's no RCA or 3.5mm jack, so consumer sources need an interface or DAC ahead of it.

Notes & Compatibility
Active near-field monitor; ports are per-cabinet. Rear balanced XLR and 1/4″ TRS inputs (use one at a time). +4dBu/-10dBV input-sensitivity switch and volume trim are controls, not ports. No RCA input — owner’s manual lists XLR and TRS only. AC mains via IEC inlet (prose).
