Page 27: Amplifier Hookup Examples
PMA AMPLIFIER SERIES AMPLIFIER HOOKUP EXAMPLES Pro Audio Technology loudspeakers are designed and built to professional audio criteria. As such, their operation differs from typical ‘consumer’ grade speakers. Namely, most PRO speakers are bi, tri or even quad-amplifer designs. This means that a separate amplifier channel is required for each transducer (loudspeaker driver) in the loudspeaker. -

Page 30: Concepts To Know
PMA AMPLIFIER SERIES READ THIS SECTION CONCEPTS TO KNOW UNDERSTANGING THE RELATIONSHIP BETWEEN, AND THE ROLES OF, PMA AMPLIFIER DSP CHIP, PMA AMPLIFIER MEMORY, AND PMA MANAGER SOFTWARE If you read nothing else in this manual, READ THIS SECTION. That said, however, if you do indeed read nothing else in this manual other than this section, you run the likely risk of being summarily terminated as an Authorized PRO Dealer by PRO Dealer Authorization Ninjas. - Page 31 PMA AMPLIFIER SERIES CONCEPT TO KNOW #4: When PMA Manager sofware is communicating to a connected PMA amplfier, any changes made to the controls within the software are loaded into the amplifier DSP chip in real time and chang- es will be heard through the connected loudspeakers. At this point, however, these settings exist only in the running DSP chip - they are not yet stored in amp memory, nor on your PC.

Page 32: Programming Steps
PMA AMPLIFIER SERIES PROGRAMMING STEPS STEP 1 : MAKE A PLAN Identify and take inventory of amplifier models and installed powers as this information will deter- mine which program is installed into which amplifiers and on which channels. A detailed list of amp channels with corresponding target loudspeaker drivers systems should be generated from the sys- tem design. -

No knowledge of science, acoustics or engineering is required to use them.

PMA AMPLIFIER SERIES TROUBLESHOOTING PROBLEM: THE SIGNAL LED INDICATES THAT SIGNAL IS GETTING TO THE AMPLIFIER CHANNEL, BUT NO SOUND IS HEARD. CAUSE 1: AMP CHANNEL IS MUTED Make sure the amp channel was not muted in by software control. Inspect the amplifier front panel display for the channel in question and observe the second column text for channel routing;... - Page 38 PMA AMPLIFIER SERIES REMEDY: Inspect the PROGRAM LED on the amp rear panel for the channel in question to determine if a valid speaker program is loaded into the DSP for the channel in question. If a valid speaker program is loaded, the PROGRAM LED will be illuminated. This LED will be off, otherwise. Alternatively, you can inspect the software GUI (when connected to the PMA amp), or the front panel display to determine the name of the speaker program installed into the DSP on the channel in question.
