CONGRATULATIONS!
Congratulations on your purchase of the Delta X6, the easy-to-use public
address system designed for gymnasiums, auditoriums, cafeterias and other large
meeting areas.
The Delta X6 contains inputs for up to two UHF wireless microphone receivers, one
input for a wired microphone and one input for a line level audio source coming
from a CD/DVD player, TV/VCR, Computer, etc. There is an adjustable-level audio
output to connect into an external source such as an assistive listening system or
recorder. Users can also connect to a passive speaker, in order to cover a larger area.
The system operates on AC power. The entire system and accessories fit nicely in the
rugged carrying case, which makes it highly transportable and lightweight.
The wireless receivers contain 100 user-selectable frequencies ranging from 620 MHz
to 694.79 MHz. Each receiver contains a clear-channel scanner (a touch of a button
automatically selects a clear frequency), low battery indicator (for the transmitter), and
adjustable squelch control. The system is available with a variety of handheld, lapel,
and headset microphones.
