Caution!
A connection to a telephone network must always be made via a telephone coupler that
provides adequate isolation between the telephone network (PBX) and the PLENA system.
The telephone coupler must also meet all relevant requirements for this type of
communication equipment as imposed by law and/or responsible telecommunication
organizations in the country of use. Never try to make a direct connection between the
telephone network and the mixer amplifier.

When using a CD player, tuner or other auxiliary device for background music, connect the

amplifier. The unit has three music source inputs:
–
two stereo Cinch inputs (Aux 1 and Aux 2) on the rear panel for music from an installed
device like a CD/DVD player or radio
– one 3.5mm stereo mini-jack input (Aux 3) on the front panel for music from mobile
devices like a mobile phone or laptop.
