3.3 CHANNEL STATUS INDICATORS
PROGRAM (RED)
This LED will illuminate when a valid PRO loudspeaker program has been installed into the
PMA DSP for this channel. If this LED is not illuminated, that means no program is installed
and audio will not pass on this channel.
By default, the PMA amplifer is shipped from the factory with no program installed to prevent
“accidents” during system setup that may cause damage to the loudspeakers in the system.
Every channel of the amplifer must be correctly programmed via PMA MANAGER SOFTWARE
prior to amplifier use.
CLIP
(YELLOW)
This LED will illuminate when the amplifier output maximum has been reached and the built-
in clip limiter is engaged. The limiter will prevent clipping from occuring.
SIGNAL (GREEN)
This LED will illuminate when a moderate input signal is detected at the input and will there-
fore “blink” in accordance with the strength of the audio content. Under high level signals,
the LED may illuminate constant.
3.4 - CHANNEL POWER LABEL
This label indicates the installed power on this channel and is placed at the factory.
3.5 - CHANNEL PROGRAM LABEL LOCATION
This outlined rectangular area will accept the blank labels provided with the PMA amplifer and
allow you to mark on the amp what program is installed in the channel. Use a perment maker
(i.e. Sharpie) to write the program on the label and affix it at this location. Alternately, use a label
maker to create your own program labels and affix them here.
3.6 - LOUDSPEAKER OUTPUTS
Connect a PRO passive loudspeaker system or bi or tri-amp speaker driver to these binding posts
making sure to observe correct polarity.
The posts will accept bare wire or dual banana plugs.
High quality banana plugs are recommended for ease of installation and system maintenance.
CAUTION: THE AMPLIFIER MODULES INSIDE THE PMA AMPLIFIER OPERATE IN BRIDGED
(“BRIDGED TIED LOAD”, OR “BTL”) MODE. AS SUCH, BOTH LOUDPSPEAKER OUTPUT POSTS
ARE CONNECTED TO HOT SIGNALS. DO NOT CONNECT ANY SPEAKER OUTPUT POST TO
GROUND, OR AMPLIFIER DAMAGE WILL RESULT.
All connectors and indicators for each of channels 2 thru 4 follow the same layout.
