Technical Details

The Spider is a simultaneous interpretation device, for whispering interpretation. The basic operation is that the interpreter speaks to a microphone, and the listeners hear through connected earphones.

The Spider has several more “goodies”, such as “in series” connection of more than one device, a Line input which is mixed with the mic, and Battery/Power adapter operation.

Microphone connection

Any standard microphone will work. You can affordable models in any electronics or sound shop. Average price is about 20 US$ or even less. (Note: microphone is not provided with the Spider)

Headphone connection

You can connect up to 15 headphones to a single box. Any type of headphone with a 3,5 mm (TRS) jack (or 6,5 mm with an adaptor) can be used. You can connect headphones, earphones, or any mix.

We recommend using affordable "earbud" type headphones. They are cheap (you will loose some or people will break them by stepping on them, so it's best to keep their cost low) but most of all, they can be shared by two people, meaning you can provide interpretation to a bigger group. (Note: Headphones are not provided with the Spider).

Power connection

A 9V battery can be used to power the Spider, when no electricity line is available. It will provide you power for about 2 hours. Alternatively, you can use a 9V or 12V power adapter, for lengthy sessions. The power consumption depends on the number of phones, so less phones means more usage time when using the battery. (Note: power adapater is not provided with the Spider).

Connecting Spiders in Series

The headphone output can be used as an input to a second Spider. The first Spider is the “Master”, and the second one the “Slave”, you simply need to set the appropriate switch on the front panel. This allows you to cater to a bigger audience.

Technically speaking, you could connect a 3rd, 4th, Spider, and so on. and thus make a wired “conference center” with an arbitrary number of earphones supported. (Note: We'll try this out during an upcoming forum and will let you know how it went).

Mixing Input Signals

You can connect a microphone and any line source, e.g. an ipod. The inputs are mixed, so for example you can do voice over music, or you can volume up the music during breaks, and silence it during interpretation.

You can use the Line input to connect it to an ALIS console system, so that you can have a mixed FM/wired system.
