What Is a Bus?

If you’re new to mixing, you may be wondering what a bus is. In every

mixer, busses provide a way to get signals from one place to another.

A bus is simply a pathway down which one or more signals travel to a

destination. This destination can be somewhere inside the console or

outside of it.

In the old days, a bus might actually be a literal wire in the mixer—when

you sent a signal down a bus, you’d feed it into the wire. When you

wanted to send two signals down the bus, you’d feed them both into the

wire, and they’d both travel together to, for example, an external effect

processor.

The great thing about busses is that they let you send a group of

signals together to some single place that they all need to go.

Traditional Busses

In a traditional mixer, there are different types of busses...sort of...even

though they’re all basically the same. Busses that carry signals to the

tracks of a multitrack recorder are called “recording busses.” Busses that

carry signals into the main mix are “mix busses.”

Typically, you’d send a signal to one of these busses by pressing a

simple on/off button that would route the signal to the bus.You might

also have a panning control that would allow you to send the desired

amount of signal to an odd-even pair of busses simultaneously, or to the

left and right sides of the stereo main mix.

The busses that carry signals to effect processors are called “effect

busses,” or “Aux busses.”“Aux” is short for “Auxiliary,” since these

busses can be used for a variety of purposes, even if they

are most

frequently used as effect busses. Aux busses tend to have expanded

capabilities, since they can be used for different purposes. They have

more than simple on/off switches: they have level controls that let you

control how much of each signal is to go down the bus. As a result, Aux

busses are actually more powerful than recording busses, since they

provide a greater degree of control.

Introducing the Flex Bus

The VM-7000 introduces a powerful new type of general-purpose bus

called the “Flex Bus.” There are 12 Flex Busses in your VM system, and

they provide all the bussing power you could need.

Since you can control the amount of signal sent to each Flex Bus, and

since Flex Busses can be linked in stereo, you can use Flex Busses for

sending signals to:

• tracks on a multitrack recorder.

• internal effects.

• output jacks connected to external effects.

• monitor feeds for studio or stage performers.

• a surround amplification system.

• anywhere else you want your signal to go. You can even send a Flex

Bus’s signals into another Flex Bus to send the signals to multiple

destinations simultaneously.

We’ll be discussing how to use Flex Busses later on.
