Used Behringer CX2310 analog channel divider. It's an older model, but at the time, it gained quite a reputation for its price and sound quality. You can enjoy the sound quality unique to analog, without going through an AD/DA converter. The scratchiness of the switch volume has been maintained, so it shouldn't be a problem for a while. However, changes in the electronic components are inevitable. Please understand this. Stereo 2-Way, Mono 3-Way crossover with 24dB/oct Linkwitz-Riley filters. A Japanese manual is also included. It can be used not only in PA settings but also for home audio. Note: (It has cannon-type input/output terminals.)
