Product Description




5-Way Binding Posts
The gold plated heavy duty binding posts ensure the purest connection. They accept up to 6AWG wire, bananas or spades.
12V Trigger In & Out
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 SPK1 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).
Adjustments for Trigger & Delay Time
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.
