Maxim III
page mute/page pass through
Effective for shipments after 4/1/19 of new units; serial numbers beginning with A19
and later (letter or number is A, B, C... and number is 19, 20, ...). For older units see
notes at the end of this section.
New units: A paging system may be connected to the Maxim III. The panel labeling is
based on a 25-volt paging input signal.
The Page Input impedance switch has three labeled positions (based on power draw
at 25V):
•
0.1W DRAW
•
1.0W DRAW
•
MUTE OFF
MUTE OFF disconnects the page input from the Maxim III. The other two settings select
transformer taps inside the Maxim III for the speakers connected to the top left and
lower right connections. These two connections are labeled A1 and A2 in Diagram A
below.
ADVISORY: These two speaker terminals are internally wired in parallel. DO NOT
connect more than two 8-ohm speakers to either or both of these terminals such that
the total load is less than 4 ohms.
System behavior for Page Mute
When a signal of adequate level (voltage) is sensed on the page mute input terminal,
all other audio inputs to the Maxim III are muted to allow the building-wide page to be
heard. The muting is applied to wireless microphones as well as computer, DVD, and
all other line inputs.
