ABX cabling setup for testing amplifiers
• Another pair of shielded audio cables for connecting the ABX to Amplifier B's inputs. One end of each
cable must have a connector suitable for the amplifier's inputs, and the other end must have either
a male 3-pin XLR or a male ¼-inch (6.3 mm) TRS connector for the ABX unit.
• A pair of two-conductor speaker cables for connecting Amplifier A's outputs to the ABX. Prepare one
end of each cable so it is suitable for the amplifier's outputs, with either a connector or stripped wire
ends, as required. The other end must have either a dual banana plug or stripped wire ends, suitable
for connecting to the ABX's binding posts labeled "AMP A."
• Another pair of two-conductor speaker cables for connecting Amplifier B's outputs to the ABX. Prepare
one end of each cable so it is suitable for the amplifier's outputs, with either a connector or stripped
wire ends, as required. The other end must have either a dual banana plug or stripped wire ends, suitable
for connecting to the ABX's binding posts labeled "AMP B."
• One pair of two-conductor speaker cables for connecting the ABX's binding post outputs, labeled "AMP
X," to the speakers. One end must have either a dual banana plug or stripped wire ends, suitable for
connecting to the ABX's binding posts, and the other end must be suitable for connecting to the
speakers' input connection.
