The microcontroller shown in the DS isn't essential. They show it controlling the muting of the amp but you can just as easily control muting with a switch (or not bother to control it at all).
Have a look at the truth table on Page 7 of the data sheet. If you connect MODE1 and MODE2 to VCC all channels will be active. Connect both MODE pins to ground and all channels will be in standby. You can do this with a switch if you want, though you'll probably want to debounce the switch.
