18. Frequently Asked Questions

18.1 Can the JB-99RT unit be connected to more than one TV monitor?

Answer: Yes, using a video distributor, the video cable coming out from the top of
the JB-99RT can be connected to 2 or more TV monitors simultaneously.

A video distributor can be purchased from CAVS or any electronic stores such as
Radio Shack.

18.2 Can the JB-99RT unit be connected to external speakers or external audio
system?

Answer: Although the mixer-amplifier of the JB-99RT has additional speaker
connectors, it is strongly recommended not to connect any external speakers
directly to the mixer-amplifier as it may cause serious damage to the mixer­amplifier and the speakers. A safer and better way is to connect from the Line Out
of the mixer-amplifier using an audio RC cable to an external amplifier, and then
connect the external speakers to the external amplifier.
