For other areas, please check with local authorities.  
1. INSPeCTION  
Your NADY AUDIO PSS-150 Portable Sound System was  
carefully packed at the factory in packaging designed to protect  
the units in shipment. Before installing and using your unit,  
carefully examine the packaging and all contents for any signs of  
physical damage that may have occurred in transit.  
Speakers and Stands  
Fully extend the speaker stand tripod legs and tighten the base  
thumbscrew. Extend the pole of the stand to the desired height  
and insert the safety pin completely through the stand hole above  
the pole thumbscrew. Lower the pole so that the pin rests on the  
holder and tighten the pole thumbscrew.  
[Please note: Nady Systems is not responsible for shipping  
damage. If your unit is damaged, do not return to NADY, but  
notify your dealer and the shipping company (if shipped to you)  
immediately to make a claim. Such claims must be made by the  
consignee in a timely manner.]  
Setup the stands on a flat surface where the speakers will be  
located and not disturbed. Place the speakers on the stands and  
position them as desired. Note: facing the speakers towards any  
of the microphones connected with the PSS-150 will increase the  
chance of feedback.

Connect the speaker cables to the input jacks on the lower left  
front panel of both the Left and �ight speakers. Connect the other  
end of each cable to the corresponding Left and �ight speaker  
outputs on the rear panel of the PSS-150 mixer section. Position  
the length of the cables so they will not be a safety hazard to  
people.  
WARNING: Connect only the supplied speakers to the PSS-150.  
Never connect additional speakers to the PSS-150.

Inputs  
2. SeTUP  
Connect all sound sources to the appropriate inputs i.e.,  
microphones, keyboards, CD players, karaoke machines.  
The supplied SP-1 Starpower™ microphone is an all-purpose  
professional stage and recording microphone with rugged metal  
construction and excellent clear, transparent sound across the  
spectrum.  
After transporting the PSS-150 to the desired location, lay the unit  
down on its flat side. Unclasp the side panel latches by pulling  
up on the yellow tab to release and unhook the latch. Carefully  
lift off the speakers and then remove the speaker stands and  
accessories from inside the unit.  
Mixer Section  
When ready to operate, plug the AC cord into the power source.  
Make sure that the unit is turned off before connecting to the AC  
power source to avoid possible loud transients which can damage  
your speakers or your ears. Before turning on, connect up the  
speakers and all inputs and outputs desired and turn down the  
Master Volume.  
Position the PSS-150 mixer section on its flat surface with the  
control panel facing up. Parts of the unit can become very warm  
during use. This is normal during operation. Care should be taken  
to ensure that there is enough space behind the Mixer Section for  
cooling. Also, do not place the Portable Sound System on high  
temperature devices such as power amplifiers, etc., or the unit  
may overheat in operation.  
Although the PSS-150 is shielded against radio frequency (�F)  
and electromagnetic interference (EMI), extremely high fields of  
�F and EMI should be avoided.  
Please make sure that the power unit supplied is marked for the  
correct voltage in your area (120VAC/60 Hz or 230VAC/50 Hz).  
Power requirements for electrical equipment differ from area to  
area. In new installations and portable sound systems, or any  
situation in which the AC power is in question, it is wise to confirm  
the voltage and use the appropriate power supply unit before  
connecting it to power sources.

the Right Speaker. When the button is depressed (Stereo mode),  
both L and R RCA input signals are mixed and sent to both  
speakers.  
(1) CHANNEL 1-3 COMBO XLR / 1/4’ INPUT  
The XLR mic inputs are an electronically balanced XLR type  
designed to accept mic level signals from any balanced or  
unbalanced low impedance (Low Z) microphone. The XLR jacks  
are configured for: Pin1 = ground, Pin2 = positive (+), Pin3 =  
negative (-). The XLR jacks have 15VDC phantom power applied  
to Pin2 and 3 for powering condenser microphones.  
(5) EFF SEND CONTROL  
The EFF SEND control adjusts the level of signal sent by each  
channel to the internal DSP (Digital Sound Processor). The  
signal sent is mono, post-Treble/Bass and will be affected by the  
CHANNEL FADER (8) setting.  
The 1/4” mono line inputs are designed to accept unbalanced line  
level signals such as those from keyboards, drum machines, or  
samplers.  
(6) TREBLE CONTROL  
Turn to the right to boost high frequencies, adding crispness too  
percussion from drum machines, cymbals and synths. Turn to  
the left to cut these frequencies, reducing sibilance or hiss. The  
control has a shelving response giving +/-10dB of boost or cut at  
10kHz.  
(2) CHANNEL 4 XLR & 1/4” STEREO/MONO INPUTS  
The XLR input is balanced, designed to accept mic level signals,  
and has 15VDC phantom power. The Left and Right 1/4” line  
inputs are for connecting stereo line level audio signals or only  
the Left/Mono jack can be used for connecting mono signals. The  
XLR input is defeated when either of the 1/4” inputs are used.  
(7) BASS CONTROL  
The bass control shelving response gives 10dB of boost or cut  
at 100Hz. Add warmth to vocals or extra punch to guitars, drums  
and synths by turning to the right. Turn to the left to reduce stage  
rumble, hum or to improve a mushy sound.  
(3) CHANNEL 5 STEREO RCA INPUTS  
The stereo RCA line level inputs can be used for connecting CD  
players, Tape Decks, and other audio equipment with line level  
outputs.  
(8) CHANNEL FADER  
The channel faders determine the output signal level to the  
Master Mix bus. They offer a smooth logarithmic taper more often  
associated with much more expensive consoles for optimum  
control of the signal.  
(4) MONO / STEREO MODE  
When the Mono/Stereo button is out (stereo mode) the Left RCA  
Aux In is sent to the Left Speaker and Right RCA Aux In is sent to

frequency response of the L and � Channel bus signal, providing  
a maximum of ±12dB of cut and boost for each frequency band

(13) FeeDBACK LOCATING INDICATORS (FLI™)  
These LED indicators will light red when there is a high level  
audio signal at the indicated frequency. These can be used  
to detect an audio feedback frequency and then lower the  
appropriate EQ fader to remove the unwanted feedback.

(Note: Observe care in selecting P.A. volume, microphone location and  
speaker placement so that acoustic feedback (howling and screeching)  
will be avoided. Please also observe the pickup patterns of the  
microphone selected: omnidirectional mics pick up sound equally from all  
directions and are prone to feedback if not used carefully. Unidirectional  
mics are more resistant to feedback, but pick up sound sources best  
that are directly in front of the mic. Also, mics that are farther from the  
sound source require more acoustic gain and thus are also more prone to  
feedback than close-source mics that are used close to the mouth.)

the Left speaker will be used as a monitor for the performers and

(16) FUSe HOLDeR & POWeR CORD CONNeCTOR  
This fuse holder contains an AC primary fuse. When this fuse blows,  
replace it with the same type fuse, size and power rating (see  
SPECIFICATIONS). If it continuously blows, stop replacing the fuse  
and refer servicing to qualified personnel. The cord connector is  
used to connect the AC power source to your power amplifier.  
(18) POWeR SWITCH  
Use this switch to power unit ON or OFF. Before turning on this  
unit, verify connection to the proper voltage AC source, check all  
connections and turn down the level controls of equipment connected  
to the outputs.  
(CAUTION: After checking the AC supply voltage, be sure that the correct  
fuse is in the fuse holder.)
