B073 1 Input 3 Output Fully Balanced Signal Selector 3-Channel Balanced Line Selector, No Need For External Power Supply Lossless Switching Product Features: Do you have one set of playback devices and three sets of balanced signal devices that need to be connected and confused? 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. One set of balanced signal input, three sets 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 LR 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 for playback and a selector for amplifiers (preamplifiers) (1) Connect the signal source device to the input COM. (2) Output terminals 1-2-3 can be connected to a maximum of 3 preamplifiers or preamplifier main amplifiers. (Please do not mistake the LR connection.) 7. When used as a preamplifier, power amplifier or power speaker selector (1) Connect the preamplifier to the input terminal COM. (2) Output terminals 1-2-3 can be connected to a maximum of 3 power amplifiers, power speakers or active monitor speakers.(Please do not mistake the LR connection.) 8. Connection Example 1: Input 1 playback signal source device and output 3 amplifiers 9. Connection Example 2: Input 1 preamplifier (Output three power amplifiers or power speakers or active monitor speakers) Product Parameters:<b
