The Cloud Z4
II and Z8 II are versatile analogue multizone

(background music, TV sound, etc.) are in use and need to
be easily combined with announcements and/or paging in
one or more zones. They have been designed to interface
directly with industry-standard paging mic interfaces, and are
compatible with Cloud PM Series paging microphones.
