XLR1
Automatic Balanced Audio Selector

The BobWire XLR1 is a two channel(stereo) balanced XLR audio A/B selector. The XLR1 will automatically switch between two XLR inputs or one XLR input and one RCA input and send the audio signal to one XLR output. The Input B XLR/RCA switch determines if Input B will be balanced(XLR) or unbalanced(RCA). The Mode switch determines whether the XLR1 will operate by audio sensing or by a 12V trigger input signal. An alternative setup would have a single audio source and the XLR1 will switch between two XLR outputs (1 IN & 2 OUT) but this is only possible in 12V trigger mode. The copper circuit board traces and the highest quality gold contact relays ensure the purest audio signal path. The ultra-sensitive audio detection circuit is 100% analog & remains out of the signal path at all times.

Input B XLR/RCA Switch

Input B can be Balanced(XLR) or Unbalanced(RCA). Set the Switch to the input type you want to use.

12V Trigger Input & Outputs

When set to "12V Mode", an input trigger voltage of 3-15VDC may be used to activate the switch (instead of audio sensing). The 12V output is active whenever the B input is selected. This output can be used to control additional equipment such as more BobWire products.

Mode Switch

The mode switch determines if the device will operate by audio sensing or 12V trigger input. In audio sensing mode, the XLR1 will automatically switch from input A to B when input B starts to play. In 12V Input mode the switch will be controlled by an external trigger voltage (3-15DC).

Sensitivity & Delay Adjustments

The sensitivity adjustment knob determines how loud the audio signal present at the B input needs to be before switching. The reset delay knob determines how long the device waits to switch back to the A input after the audio stops on input B.
