Two piece kit includes a sender and receiver. Cable testers provide a quick check of XLR cables -- even when cable ends are in a different locations.
Works on either phantom power from the board or power supplied by the sender unit. Attach sender and receiver to opposite ends of the cable or use the receiver alone if phantom power is present. Shows if the cable is good or bad via 3 two-color green and red LEDs.
Battery powered. It's only ON when in use. Long battery life. 5/8” diameter by 3” and 5”
