Spider Audio Merger & Splitter
The Spider Audio Merger & Splitter is not an effect device, but a utility. It has two basic functions:
D To merge up to four audio input signals into one output.
D To split one audio input signal into four outputs.
There are no controls on the front panel of this device, only signal indicators.
Merging audio
On the back panel of the Spider are several audio connectors. The left half of the panel contains four stereo audio in-
put connectors, and to the right of these, one merged stereo output.
D The principle is simple; all audio signals connected to any of the four inputs will be merged and output via the
output connectors.
If you connect a mono signal (to a L/Mono input, with nothing connected to the corresponding R input) it will be
output on both merged outputs. This way you can merge stereo and mono signals freely.
If you connect a signal to the R input only (with nothing connected to the corresponding L/Mono input) it will be
output on the R output only.
Practical uses of merging audio
There are many practical uses of merging audio signals together, for example:
D Process several audio signals with the same insert effect(s).
Perhaps you want to process certain channels in a mix with the same compressor, or use one ECF-42 to filter a
group of instruments in a mix. You can also set up a chain of insert effects and process the merged signals.
D Sub-grouping signals.
It may be practical to control several audio signals using one channel strip in the Mixer.
D Use merged signals as either carrier or modulator source for the BV512 Vocoder.
You could use several sounds as carrier signal, or modulate the carrier with several signal sources.
