2. SETUP

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

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 Portable Sound System is shielded against
radio frequency (RF) and electromagnetic interference
(EMI), extremely high fields of RF 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.

Europe (except UK): 230V, 50Hz

UK and Australia: 240V, 50Hz

USA and Canada: 120V, 60 Hz

For other areas, please check with local authorities.

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.

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 Right speakers.
Connect the other end of each cable to the corresponding
Left and Right 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

Connect all sound sources to the appropriate inputs i.e.,
microphones, keyboards, CD players, karaoke machines.
The supplied SP-1 Starpower™ microphone is an all­purpose professional stage and recording microphone with
rugged metal construction and excellent clear, transparent
sound across the spectrum.

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.

(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.

The 1/4" mono line inputs are designed to accept
unbalanced line level signals such as those from
keyboards, drum machines, or samplers.

(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.

(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.

(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

(12)(11)(10)(9)

In is sent to the Right Speaker. When the button is
depressed (Stereo mode), both L and R RCA input signals
are mixed and sent to both speakers.

(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.

(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.

(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.

(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.

(9) DSP EFFECTS DISPLAY

This is displays the selected effect out of 16 possible effect
presets.

(10) DSP EFFECTS SELECTOR

The UP/DOWN buttons allow fast and easy scrolling in
either direction through the 16 effect presets.

(11) POWER ON INDICATOR

This LED lights blue when the unit is ON.

(12) 5-BAND GRAPHIC EQ

The 5-band channel graphic equalizer allows you to adjust
the frequency response of the L and R Channel bus signal,
providing a maximum of ±12dB of cut and boost for each
frequency band from the flat position. The faders can be
adjusted to easily eliminate feedback from the
corresponding FLI™.

D — DLY 300ms
E — DLY 400ms
F — DLY 500ms

(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 andthus are also more prone to
feedback than close-source mics that are used close to the
mouth.)

(14) AUX RCA OUTPUTS

The Left and Right RCA outputs provide line level signal
output to a cassette deck, home audio equipment, or a
recording device.

(15) L/MONITOR and R/MAIN MASTER FADERS

These control the final level of the signal sent to the left and
right SPEAKER OUTPUTS (19) outputs and the AUX RCA
OUTPUTS (14). These are also named Monitor and Main
for situations when the Left speaker will be used as a
monitor for the performers and the Right speaker will be
positioned towards the audience.

(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.
