iMPoRTanT safeTY insTRUCTions
When using this electronic device, basic precautions should always be taken,
including the following:
1. Read all instructions before using the product.
2. Do not use this product near water (e.g., near a bathtub, washbowl, kitchen sink,
in a wet basement, or near a swimming pool, etc.).
3. This product should be used only with a cart or stand that will keep it level and stable
and prevent wobbling.

7. The product should be connected to a power supply only of the type described in the
operating instructions or as marked on the product. Replace the fuse only with one of the
specified type, size, and correct rating.
8. The power supply cord should: (1) be undamaged, (2) never share an outlet or extension
cord with other devices so that the outlet’s or extension cord’s power rating is exceeded,
and (3) never be left plugged into the outlet when not being used for a long period of time.
9. Care should be taken so that objects do not fall into, and liquids are not spilled through,
the enclosure’s openings.
10. The product should be serviced by qualified service personnel if:
A. The power supply cord or the plug has been damaged.

Panel ConTRols and ConneCTions
1. INPUTS
The electronically balanced XLR MIC input is designed to accept signals
from any balanced or unbalanced low impedance (Low Z) microphone. This
input can also be used for low line level signals. Make sure to turn down
the preceding unit to avoid distortion. The XLR jack is configured for: Pin1 =
ground, Pin2 = positive (+), Pin3 = negative (-). Note, the Mic input is more
sensitive than the Line input.
The 1⁄4” TRS LINE input is designed to accept balanced or unbalanced
linelevel signals such as those from keyboards, drum machines, or samplers.
If a balanced signal is to be connected to the line input, then a 1/4” TRS
(stereo) phone plug should be wired for: Tip = positive (+), Ring = negative
(-), Sleeve = ground.
Note: Both Mic input and Line input can be used simultaneously if desired, however audio
levels cannot be adjusted separately.
2. LINE OUT
This 1⁄4” unbalanced output can be used to daisy-chain multiple PM-200A or
send the input signal directly to a mixer, PA system, or recording device. The
Line Output is not affected by the Volume controls or EQ.
3. VOLUME
This adjusts the signal level sent to the internal speakers, external speaker,
and headphone outputs.
MAKE SURE TO AVOID EXCESSIVE CLIPPING OF THE POWER AMPLIFIER!!!
The Volume should be adjusted to be comfortably audible without excessive
clipping. The red clipping LED indicator, located on the front baffle, will light
when the amplifier is within 3dB of clipping. It is acceptable if the red LED
lights occasionally. If the red LED lights more than occasionally, you should
turn down the volume to avoid audible distortion and possible damage to
the speakers or amplifier. The PM-200A uses a high power amplifier in a small enclosure for
maximum power and portability combined. Care should be taken to avoid overheating and
possibly damaging the power amp or speakers with excessive clipping.
Note: Speakers and amplifiers damaged due to hard clipping are not covered under warranty.
4. EQ
The three-band equalizer section utilizes a HIGH, MID, and BASS EQ control, each of which
has 12dB of cut and boost, with a center detent for off indication. The frequency response is
flat when all three EQ knobs are in the center detent position. The HIGH and BASS shelving
controls have their frequencies fixed at 10 KHz and 120Hz respectively. The MID control has
a peaking response at 2.5KHz. The EQ is a valuable feature of the PM-200A as it allows the
user to control the tonal characteristics of their monitor mix. For example, boosting the BASS
can fatten the sound, add warmth to vocals, or extra punch to bass, drums and synths; the MID
control can be used to define the midrange or bring out the vocals; and adjusting the HIGH
control can provide a crisp sounding high end for high hat and vocal clarity.
Another very important, yet often overlooked technique is
to use the EQ to subtract from the mix. Cutting the HIGH
control can reduce unwanted sibilance, hiss, cymbals, or
high frequency feedback, while attenuating the MID or
BASS can also eliminate feedback or clear up a muddy
sounding mix. Cutting the HIGH and BASS, then pushing
up the Volume control is equivalent to a mid range boost!

Panel ConTRols and ConneCTions
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 flat 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 configuration, 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 baffle
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.]

10. FUSE COMPARTMENT
Replace with only the same type fuse. If the fuse blows continuously, have the unit serviced by
qualified personnel. The PM-200A powered mixer uses 20mm glass tube Fast Blow fuses: 6A
250V for 115VAC, 3A 250V for 230VAC.
11. AC VOLTAGE SELECTOR SWITCH
Before plugging in the power cord, check to see that the unit is set for the proper voltage for
your area: ~115V (60Hz) or ~230V (50Hz).
12. HEAT SINK
The heat sink can get very hot during high power operation. Make sure to leave properly
ventilated and avoid touching.
13. MOUNTING SOCKET
On the bottom panel of the PM-200A
is a 5/8” dia. socket for mounting the
PM-200A on a mic stand. Depending
13
on your mic stand, you may require
the optional MSA-100/200A Mic Stand
Adapter for most secure mounting. For
ordering, see PM-100/200A Optional
Accessories Ordering Form included.
