Bogen PM-3180 User manual

The PM3180 amplifier incorporates three indepen-
dent amplifier channels with a unique digital interface,
providing the ideal solution for restaurant, lounge/bar
hotel, factory or similar facilities where multiple pro-
gram and paging inputs need to be distributed to sep-
arate areas and automatically switched.
The PM3180 provides up to 4 AUX inputs and 2 MIC
inputs that can be individually assigned to each ampli-
fier channel (one of the mic inputs can be pro-
grammed for telephone paging applications). Each
input on a particular channel can also be assigned a
priority level; the amp channel will then automatically
switch inputs based on input activity. Microphones can
be assigned to the highest priority levels: 1or 2; and
aux sources to levels 3, 4, 5, or 6. For example, a pag-
ing microphone can be assigned priority level 1, a juke-
box to level 3, and a radio to level 4. In this configura-
tion, the radio will play until the jukebox becomes
active; both inputs are overridden when the page
microphone is activated.
The three integrated amplifier channels are rated at
100, 60, and 20 watts. All amplifiers have separate 4-
and 8-ohm outputs as well as 25 and 70 volt taps.
Audio processing inserts are also included for each
amp channel to facilitate the connection of external
signal processing equipment. Adjustable input trim
controls adjust for differing audio source input levels.
The PM3180 includes a variety of useful features,
including phantom power and automatic level control
for microphones, choice of microphone precedence
activation (VOX, Contact N.O., Contact N.C.), vari-
able mute, and automatic fade-in of audio source after
a mic page or when switching to a lower priority.
All control functions can be adjusted from the front
control panel, which is itself removable for installation
in a remote location away from the amp chassis. An
infrared wireless remote control unit is also included
and permits full control of all functions.
The amplifier has a user mode that lets personnel
adjust the volume, bass and treble levels and manually
select input sources. A separate programming mode
lets the installer customize system operation, includ-
ing the ability to preset the power-up volume level of
each input, preset treble and bass responses, and lock-
out or inhibit volume, bass and treble controls, set pri-
orities, and many more system parameters. All pro-
gramming steps are displayed and verified on the unit’s
large alphanumeric LED display panel. Programming
can be accomplished using the control panel or
infrared remote control unit. All programming is pass-
word-protected.
With tremendous flexibility, the PM3180 provides an
elegant solution to multi-zone sound management.
