Some channels are called The term <u>busesbus</u>, which is a very generic term but and can refer to any sort of connection to transfer audio in the mixer. However, it generally refers to channels that are handling ''groups'' of inputs...or other buseschannels. For example, the master output channel is often called the master or main bus, as all the other channels are routed through it before being sent out of the mixer. There may also be an auxiliary (or "aux") bus for an alternative mixthat carries the signal from a subset of the available channels. Then there may be buses for certain instruments that require  When multiple input channelsare all routed into a single channel, that channel is called a bus. For instance, drums typically require numerous microphones to capture the entire kit's sound - all those mics are fed into separate input channels which are all routed to a ''drum'' bus, where they can be processed together before being output to the master bus. This makes it much simpler and quicker to adjust the volume of the drum kit as a whole, for example. Types of instruments can be routed this same way - guitars to a guitar bus, background vocals to a vocals bus, brass instruments to a brass bus, etc.
