XLR-0301/0103 Audio Signal Selector XLR Balanced Audio Switcher Audio Selector for 1 Input 3 Output

XLR-0301/0103 Audio Signal Selector XLR Balanced Audio Switcher Audio Selector for 1 Input 3 Output

Features:
- Pure aluminum shell, brand signal cable, XLR sockets for REAN, Taiwan-made selector switch and Japan-made soldering tin
- The RCA audio switch supports 1 input 3 output
- Application: 1. switch between audio sources (such as CD players, digital players, set-top boxes, radios and decoders) and power amplifiers (or active speakers); 2. Switch between the front and back stages of power amplifiers

Passive Audio Selector Standard Version:
- Shell material & process: It is made of pure aluminum with brushed process, and its front panel is 3mm in thickness
- Audio signal cable: Silver-plated unshielded wire
- Transfer switch: Audio universal rotary switch made in Taiwan
- Knob: Made from aluminum shell and plastic core
- XLR sockets: gold-plated for REAN (made in China)
- Switching line (pin 1: shielded layer, pin 2: to + end, pin 3: to - end): + end and - end can be switched, but shielded layer can not be switched; Directly connected and connected to the housing; Suitable for all equipment to use in accordance with the standard

About Ground Loop:
1. The ground wire of all the equipment that constitutes the entire sound system forms one or more closed loops. When the electromagnetic waves of space pass through the plane formed by the loop, the ground wire will induce noise current. If your equipment indicators are not good at this time (usually the balance circuit imbalance causes the shielded layer to have audio signal current), then the noise current will superimpose the audio current to form audible noise.
2. Causes of the formation of the ground loop:Its shell is connected to a safe ground wire, the equipment share a DC power supply, multiple pre-amplifiers share a signal source, multiple signal sources share a pre-amplifier, multiple decoders share a digital source (CD player or digital output of digital player), multiple digital sources share a decoder (non-optical fiber) and other reasons; the ground wire is made to string together into a closed loop.
3. Solution: Do not use fake balance equipment in the first place. The so-called false balance is that the socket is balanced, and in fact, the - end may be shorted to ground. Use an active switcher; Isolators can be used for public performances, but audiophiles should use isolators sparingly.
