The multiple input adapter box has various cables and connectors that allow you to connect from almost any electronic audio source to the house sound system (the XLR mic-level input of the typical chapel and cultural hall). However, the adapter box cannot be used with mic-level audio sources (for example, a microphone).
The multiple input adapter box is sometimes referred to as a crab box because of its many cables. There are a variety of models, so you can connect any device to the sound system, including a telephone system. For example, it can be used to back up the audio of a Church broadcast if the satellite or internet stream fails.
HOW TO USE IT
An electronic audio source, such as those listed above, can be connected to a sound system using a crab box in three simple steps.
- Choose your electronic audio source.
- Choose the correct cable from the crab box and plug it into the electronic audio source.
- Plug the crab box into the sound system port.
- Older meetinghouse sound systems do not have a line-level input (such as an RCA jack). Where this is the case, the EJ-8 and EJ-10 allow the connection of any non-mic-level signal into the building sound system. Since the EJ-8 and the EJ-10 each have a volume control, various input devices, such as a DVD player with soft audio, can be adjusted for appropriate sound levels.
- Crab boxes have a hum switch, which can help reduce unwanted noise in the system. The Church issues at least one audio adapter box to each building. It is usually stored in the resource center.
