B072 3 Input 1 Output Fully Balanced Signal Selector 3-Channel Balanced Line Selector, No Need For External Power Supply Lossless Switching

Product Features:
Do you have 3 sets of balanced XLR signal devices and 1 set of balanced XLR signal output that need to be connected and get stuck?
A powerful balanced signal stereo selection switcher can solve the problem of multi-device connection plugging and unplugging, without the need for an external power supply and with lossless switching
1. 3 sets of balanced signal input, 1 set of balanced signal output
2. The switching switch adopts a three-position rotary high-contact, high-precision and reliable knob switch, ensuring lossless switching.
3. A non-short switching mode is adopted. It adopts the simultaneous switching mode of HOT and COLD. Note: All inputs and outputs of GND are universal.
4. The LR of the input and output terminals is symmetrically configured on the left and right, and the LR of the internal wiring is separated on the left and right, with a L/R separation structure.
Reduced mutual interference among LRS.
5. When switching the operation and rotating the gear switch, there will be no popping sound, which does not affect the sound quality and ensures lossless transmission
6. When used as a signal source device and a selector for amplifiers (preamplifiers)
(1) Input terminals 1-2-3 can be connected to a maximum of 3 playback signal source devices.
(2) The amplifier (preamplifier or preamplifier master) is connected to the output terminal COM. (Note: Please do not mistake the L/R connection.)
7. When used as a preamplifier, power amplifier or power speaker selector
(1) Input terminals 1-2-3 can be connected to a maximum of 3 preamplifiers.
(2) Connect the power amplifier or power speaker or active monitor speaker to the output terminal COM.(Note: Please do not mistake the L/R connection.)
8. Connection Example 1: Input 3 playback signal source devices and output 1 amplifier
9. Connection Example 2: Input 3 preamplifiers (Output one power amplifier or power speaker or active monitor speaker)
