From the vendor
Buffered version of the ABY switch. The signals at the A and B outputs are independent of each other and enable the connection of two different amplifiers or splitting the signal into two paths. The standard, non-buffered ABY switch often has problems working with two different amplifiers at the same time. In this case, one amplifier works properly and the other lacks gain - here, thanks to the use of buffers, this effect does not occur and everything works perfectly.
PCB. Dimensions: 59mm x 32mm.
