1. A liquid ejecting apparatus comprising:
an ejecting unit that ejects liquid when a drive signal is supplied to the ejecting unit;
a drive signal output unit that outputs the drive signal;
a cooling unit that cools the drive signal output unit; and
a power supply unit that supplies power to the cooling unit, wherein
the liquid ejecting apparatus has a first mode in which the drive signal output unit outputs a first drive signal of a first frequency as the drive signal to the ejecting unit, and a second mode in which the drive signal output unit outputs a second drive signal of a second frequency lower than the first frequency as the drive signal to the ejecting unit,
an amount of power supplied by the power supply unit to the cooling unit in the first mode is larger than an amount of power supplied by the power supply unit to the cooling unit in the second mode, and
the first mode is a binary mode, and the second mode is a multi-gradation mode.
