The Extreme Extender was designed to solve ADAT Optical distance limitations. The Extreme Extender ADAT IN converts ADAT optical to HearBus CAT5E cable. Using CAT5E the effective length of an ADAT optical interface can be extended up to 500 feet. This is accomplished without any loss of audio quality. In addition to acting as an ADAT optical extender, the Extreme Extender ADAT IN may be connected to the Optical output of any ADAT device, such as a DAW, Mixer, etc. and connected to the input of a Hear Back Hub. The Extreme Extender ADAT IN is powered using a small external power supply.
