Nady Systems PM-200A Snow Blower User Manual


 
Note, the PM-200A internal speaker has been specially designed to reduce feedback
frequencies while allowing maximum punch from center vocal and instrument tones. This
allows clear and comprehensive monitoring with the speaker in close proximity with maximum
feedback rejection. The speakers are not meant to be at in audio quality or used for music
reproduction. But when the band or DJ is pumping, they kick out exactly what you need...and
then some!
5. EXTERNAL SPEAKERS
The PM-200A can also be used to power external speakers for additional
monitoring or added volume. Each External Speaker jack can power any
number of speakers with a total impedance not being less than 8Ω.
The PM-200A actually uses a dual power amp, each side of which is
used to power the internal 8Ω speakers. The power amp is capable of
delivering up to 50W RMS of clean power to EACH SPEAKER.
When additional speakers are connected to the two External Speaker
outputs, they are automatically wired in parallel with each internal
speaker, reducing the total impedance of each channel. If an 8Ω speaker
is connected to each output, the power amp can deliver up to 75W RMS
to each channel – that means 37.5W per speaker. If the internal speakers
are turned off in this conguration, each 8Ω external speaker
can receive up to 50W RMS of power.
6. INTERNAL SPEAKERS ENABLE
When external speakers, or headphones, are being used, it may be
desirable to turn off the internal speakers to decrease noise, or, to increase
the power somewhat to the external speakers. When the External Speakers
push-button switch is depressed, the internal speakers are enabled. When it
is out, the internal speakers are disconnected.
7. HEADPHONES
The Headphone 1⁄4” stereo output can be used to monitor the signal post
Volume and EQ. It is capable of powering headphones with impedances of
8Ω or greater. The internal speakers can be used simultaneously or turned off
using the Internal Speakers Enable switch.
8. POWER
This switch turns the AC power on and off as indicated by the front bafe
green Power Led.
9. POWER CONNECTOR
The IEC jack is used to connect the power cord to the AC Power Source.
[Caution: Never remove the center grounding pin as this can cause
a serious safety hazard and will immediately void your warranty.]
