Chapter 1 Before You Start (VS-880EX Terminology)

Mixer Section

The digital mixer specifies input or output status of the recorder section. The VS- 880EX contains an Input Mixer located before the recorder section, a Track Mixer located after the recorder section, an Effect Return Mixer which controls the effect return and Stereo In (p. 152), and a Master Block which determines the output jacks from which the signal of each mixer will be output.

*For more detailed information about the mixer section, please refer to the “Mixer Section Block Diagram” (Appendices p. 120).

Signal Flow (Buses)

On the VS-880EX, signals flow through buses. buses are shared lines through

which multiple signals can be routed efficiently to multiple tracks or chan-

nels. It may be easier to understand this if we use the analogy of water pipes.

For example, the water that is supplied by the water company to your house is branched to a variety of locations within the house (kitchen, bathroom, toilet, etc.). The water that is used at each of these locations is then collected into the sewer, and carried away.

OUTPUT

Drain (Bus)

If we think of the VS-880EX as the house, the water being supplied from the water company corresponds to inputs such as mic or guitar. Some of these inputs are sent to recording tracks and are recorded. Other portions are sent to the effects, and reverb or chorus are applied before they are output.

The basic principle of the VS-880EX is that by specifying in this way from where and to where the common lines run, you can determine which input signals will be recorded on which track or sent to which effects, and where they will be out- put.
