Amplifier switcher speaker selctor

This is an amp switcher/speaker switcher. You can choose 2-IN-1-OUT for 2 amplifiers to 1 pair of speakers, or in reversible direction of 1-IN-2-OUT for 1 amplifier to 2 pairs of speakers (Note: this way is switch one pair loudspeaker A or loudspeaker B work, They don't work at the same time). So you could compare 2 amps or 2 pairs of speakers quickly and conveniently. You can easily with just one press of for A/B switch. This is a passive non-powered device. Plug and play In/Out through the high quality golden plated banana jacks, which can accept up to 12 gauge wires.The internal connection wire uses UL1015 14 AWG wire, which is enough to pass high current.Power rating: 100W RMS, 200W Peak for each channel. No protection or impedance matching circuits internal, so could not affect sound quality, but If you have a tube amp you need to make sure the tube amplifier is connected to a load before switching. Using a high quality 10A contacts silver plated 4PDT Toggle switch, has 12 connectors/2 position ON/ON. It does not have common ground(we do not want to have common ground between two amps, this could negatively affect their performance (and sound quality) and in some cases also case damage – there are amps that have fully balanced outputs and cannot have common ground between speaker connectors, for example some Class D amps.) 2 way amp switch: it work to accept two amplifiers or receivers to share use of one pair of loudspeakers through the toggle switch on the front (Switch AMP/A or AMP/B) on this way you can quickly compare 2 amps, A/B test them without having to make long pauses for switching the amps off, disconnecting speaker wires from one amp and connecting them to the other amp. 2 pairs speakers switch: it work to accept one amplifiers or receivers to switch two pairs of loudspeakers (Note: this way is switch one pair loudspeaker A or loudspeaker B work,They don't work at the same time.
