    Before the TX3 is connected to the mains supply, make sure that the unit is selected for operation with the correct mains voltage. This can easily be checked by looking at the rear panel, where the selected input voltage appears on the voltage selector itself, located near the mains socket.

  • Page 4: Input Connections

    Where the device connected at the input (i.e. console) and at the output (i.e. amplifier) is balanced, there is no hot and cold pin to worry about : the TX3 is neutral polarity with pin to pin connections (pin 1 to pin 1, pin 2 to pin 2, pin 3 to pin 3). Note that the connection to pin 1 should be made using the cable shield.

    Where amplifiers with unbalanced inputs are used, the ‘hot’ or +ve pin of the amplifier input should be connected to either pin 2 or pin 3 of the TX3 output XLR, according to which pin is the ‘hot’ pin on the device connected at the input. The unused signal pin (3 or 2 respectively) should then be linked to pin 1 for grounding.

    Fuse replacement. Disconnect the TX3 from the mains power supply, and pull back the fuse drawer located at the bottom of the mains input. (A small screwdriver may be helpful.) The fuse drawer has two compartments, one containing the fuse under operation and the other a spare.
