Audio Switcher Amplifier Speaker Switch Converter 2 Input 1 Output/ 1 In 2 out 2

Description

Standard Version: 2.5 square 4N oxygen free copper wire
Upgraded version: Taiwan imported single crystal copper silver plated wire
This switch uses small binding posts
Two-channel amplifier speaker switcher, two in and one out (or one in and two out)
Function description:
1. Two two-channel amplifiers turn to a pair of speakers; or one two-channel amplifier to two pairs of speakers. No need to remove the wire frequently! Equipment PK is more between hands! Use silver alloy contact switch, 2.5 square 4N oxygen-free copper wire or Taiwan imported single crystal copper silver plated wire, pure copper plated small binding post. Senior enthusiasts hand soldering, great value! !  2. As a sound/music enthusiast with a certain burning age, it is common to have two or more speakers or more than two amplifiers in the home. In order to balance HIFI and AV, sweet and speed, it is not a way to plug in the speaker cable, and even affect the mood of listening to music.  3. This switch is a passive device, which is simple and does not have to worry about sound dyeing. The selected parts are soldered by hand using soldering station. 4. You can enter and exit or turn in two in and out, and the left and right channel grounds are completely separated. 5. Use high-current silver alloy contact switch, the contact resistance is ultra-low, and the silver contact relay of OMRON 30A is comparable, see the bridge picture. Popular point of view Errata: Silver is a metal that is very susceptible to oxidation, especially as a switch contact, when large currents have temperature. Usually the high-quality switches or relays used in civilians are silver alloys, and it is absolutely impossible to use pure silver. Our OMRON relay supplier confirms this. Another way to fill nitrogen or oil immersion
Amplifier Protection ：
Shell material: pure aluminum brushed shell.      The switch is a passive device, which is simple and does not need to worry about sound dyeing. Selected parts are welded by hand using a soldering station.      You can enter one or two out or tune in two in and one out, the left and right channel grounds are completely separated.      Using 10A high current silver alloy contact switch, the contact resistance is extremely low, which is comparable to OMRON's 30A silver alloy contact relay, see the bridge picture. Single crystal copper version switch can be upgraded to 25A (25A non-standard configuration).          If it is used as two inputs and one output (one gallbladder, one stone or two gallbladders), please note that the output of the amplifier cannot be empty! ! Please select the model with amplifier protection, pay attention! ! (Principle: The amplifier uses a transformer output. The transformer belongs to the inductance category and has a freewheeling characteristic. When the amplifier loses its load suddenly during operation, it will generate 3 to 5 times the B + voltage between the primary and secondary, such as 300B single-ended The operating voltage is 400V, then the induced voltage is up to 2000V, it is likely to break down the output transformer. At present, most amplifiers are protected, please consult the equipment manufacturer for details, if you are not sure whether the amplifier is protected, for safety reasons Please select a model with amplifier protection, or do not turn on both amplifiers simultaneously)
