==============================================

Two-channel amplifier speaker switcher, two in and one out (or one in and two out)

Function descrtion: Two dual-channel power amplifiers can be converted to a pair of speakers; or one dual-channel power amplifier can be converted to two pairs of speakers. No need to unplug and plug wires frequently! Equment PK is even between raising hands! Use sier alloy contact switch, 2.5 square 4N oxygen-free copper wire or Taiwan single crystal copper sier-plated wire, pure copper gold-plated small terminal. As an audio/music enthusiast with a certain age, it is common to have more than two pairs of speakers or more than two power amplifiers at home. In order to balance HIFI and AV, sweetne and speed, often plugging in and out of the speaker cable is not a solution, and it even affects the mood of listening to music. This switcher is a paive device, simple and does not have to worry about sound dyeing, and the selected parts are purely hand-welded with a station. A 20-year veteran enthusiast. It can be one-in, two-out or adjusted to two-in and one-out. Using high-current sier alloy contact switch, the contact resistance is ultra-low, comparable to Omron’s 30A sier contact relay, please refer to the ture of the bridge. Errata of popular opinion: Sier is a metal that is very easy to oxidize, especially as a switch contact, when there is a high current and temperature. Generally, the sier contacts of high-quality civilian switches or relays are sier alloys, and it is absolutely impoible to use pure sier. Our Omron relay supplier confirmed this. Nitrogen or oil immersion is another matter!

Order descrtion:

Type A and Type B are only different in the case material. Type A is an iron plastic case, and Type B is an all-aluminum wire-drawing case. Both use 2.5 square 4N oxygen-free copper wire. C type and B type chais have the same shell material, only the wires are different, C type uses single crystal copper sier-plated wire.

Witne the moment of quality! Please see the impedance value of the switcher at a test frequency of 1000 Hz with a digital bridge: 1.9 milliohms. What does it mean? For example, the contact resistance of a wire in a power amplifier or any signal plug soet will be greater than this value.
