is used to connect
devices such as laptops and MP3 players to house
sound systems in conference rooms and auditoriums.

single mono XLR output. Transformer isolation provides
immunity from hum & buzz caused by ground loops and
RF interference.
Additional features include a volume control for quick
level changes and a ground lift switch for eliminating
noise issues common with consumer audio devices.
