Speaker splitter (switch) with volume control separately for each pair. It allows you to connect 4 pairs of 8ohm speakers and includes inputs for two stereo amplifiers. It allows you to turn on / off each speaker pair individually, select the amplifier and adjust the volume, a simple 2:4 matrix system (you can choose on the hub which sound source will play in what pair). Switching power 100W RMS per channel. The recommended impedance of the connected speakers is 8ohm. The volume controls have 12 positions. This switch balances the impedance of the load and is also suitable for mounting up to 19" RACK.
