Liquid discharge apparatus

A liquid discharge apparatus comprising:

• a liquid discharge head configured to discharge a liquid;
• a drive substrate provided with a drive-signal generation circuit configured to generate a first drive signal and a second drive signal for driving the liquid discharge head and an output connector configured to output the first drive signal and the second drive signal;
• a first wire configured to supply the first drive signal to the liquid discharge head;
• a second wire configured to supply the second drive signal to the liquid discharge head;
• and
• a single relay substrate disposed between the drive substrate and the first and second wires, and configured to relay the first drive signal and the second drive signal from the drive substrate to the first wire and the second wire,
• wherein the single relay substrate includes:
• a relay connector configured to be directly connected to the output connector without a wire being interposed therebetween;
• a first connector configured to be connected to the first wire and configured to output the first drive signal supplied from the output connector to the relay connector to the first wire;
• and
• a second connector configured to be connected to the second wire and configured to output the second drive signal supplied from the output connector to the relay connector to the second wire.
