In the VM-3100, channel signals get from one place to another by

traveling through “busses.” A bus is simply a pathway down which one

or more signals can travel. The VM-3100 utilizes a variety of busses—

with different names and purposes—but they’re all basically the same

simple thing: pathways. What’s great about busses is that they allow you

to easily group together a bunch of signals and send them anywhere

you like.

You’ve actually already been working with busses. When you sent your

drum machine, bass and vocal to Effect 1 back on Page 14, you were

actually using the VM-3100’s mono FX bus. (The VM-3100Pro has two

mono FX busses, one that carries signals to Effect 1 and another that

takes them to Effect2). And throughout this

Supplemental Note

, you’ve

been listening to signals sent from their channels into the stereo main

mix bus. Unless they’re muted, channel signals are

always

sent to the

main mix bus—when you raise or lower a channel’s fader, you’re

controlling how much of its signal is going to the main mix bus. The

stereo main mix bus delivers signals to the MASTER OUT L and R (for

“Left” and “Right”) jacks and also to the MONITOR headphone jack.

Busses in the VM-3100 often carry signals to output jacks. To route a

signal to a particular output jack, therefore, you can simply send the

signal down the bus that’s connected to it. You can send as many

signals as you want to a jack by sending them to the bus that feeds it.

In addition to its FX and main mix busses, the VM-3100 provides

another eight mono busses—numbered 1 through 8—that can bring

signals to other output jacks:

• Busses 1 and 2 carry signals to the AUX SEND 1 and 2 jacks, also

labeled as Jacks 1 and 2, respectively.

• Busses 3 and 4 carry signals to the BUS OUT L and R jacks, also

labeled as Jacks 3 and 4, respectively.

• The stereo DIGITAL I/O Out jacks A and B are special cases.You

can connect them to any odd/even pair of busses (1 and 2, 3 and 4,

and so on). This affords you tremendous flexibility and convenience

when you want to send signals digitally from the VM-3100 to

another device. As configured at the factory, Busses 4 and 5 feed

Digital Out A, and Busses 7 and 8 carry signals to Digital Out B.

The VM-3100’s eight digital RMDBII/R-BUS tracks also get their signals

from Busses 1-8. Any of the eight busses can be routed to any R-BUS

track.

XVI. Understanding Busses

When you send a channel’s signal to a bus, you’re actually sending a

perfect digital copy of the signal, not the signal itself. The original signal

remains in the channel. As a result, you can send it to several busses

and destinations—for example, you can send a signal to a send-and-

return effect

and

to the main mix, as we did in our send-and-return

effect example.

A bus can be mono—a single stream of signals—or stereo, with its

signals distributed across two streams of audio.
