Split box
The Splitbox (engl. Aufteilkasten ) is a device in the field of sound and event technology . It is always used when audio signals are distributed and used multiple times. The splitbox is mainly used at events which, in addition to mixing and recording audio signals, also include sound reinforcement . In simplified terms, the split box divides individual input signals into several (usually three) identical output signals without weakening or otherwise changing the level of the output signal compared to the input signal. For this reason, a split box has an integrated signal amplifier or transmitter .
A split box has a certain number of inputs (e.g. 32) and a multiple of this number of outputs (e.g. three for each individual input). This means that a signal - for example that of a microphone - can be used both for sound reinforcement and for recording on, for example, DAT , as well as for mixing and recording on hard disk or magnetic tape . As a rule, only the signals that are used several times are passed through the split box. When recording with an audience, for example, it is usually not necessary to split the atmospheric microphones over the split box, as they are only intended for mixing and recording and not for sound reinforcement.
As a rule, a split box is followed by a stage box or a mixer .
