WARNING
PROLONGED EXPOSURE TO HIGH SOUND LEVELS
Podium Pro Audio PP1003A loudspeaker is capable of
generating sound pressure levels (SPL) sufficient to cause
permanent hearing damage to performers, production crew and
audience members. Caution must be taken to avoid prolonged
exposure to SPL levels in excess of 90dB. For example: Always
place the speakers in such a manner that no audience members
or personnel are continuously exposed to sound levels in
excess of 90dB.

INSTALLATION
Podium Pro Audio speakers are intended for portable applications where the
speakers will be placed directly on the stage floor or mounted on a suitable
speaker stand.
VERY IMPORTANT: This product is NOT intended for permanent
installations. Such installations must follow rigorous standards, including
cable or chain rigging for safety. No rigging anchor points are provided and
any attempt to modify the enclosure for this purpose will weaken the
structure. Therefore, any overhead placement requiring rigging cannot be
considered safe.
FLOOR PLACEMENT: Speakers should be placed in a secure, dry and level
location. Be sure to cover or tape down any cabling that crosses a traffic lane.
Try to place the speakers between the microphone(s) and the audience. This
will minimize acoustic feedback.
STAGE “FOLDBACK” MONITOR: Place the PP1003A on its side, along the
front edge of the stage aimed toward the performers. Exact placement is
strongly influenced by type and placement of the microphone(s).
STAND MOUNTING: Podium Pro Audio speakers are compatible with
standard 1-½” (38mm) stands.
Tip: Sound quality and coverage area are best when the tweeter is between
2 to 4 feet above the audience ear level.
•
•
•
•
•
•
•
Speaker stands must only be used on smooth level surfaces.
Be certain you select a stand rated for at least 40lb. Contact your
dealer for recommendations.
NEVER MOUNT MORE THAN ONE SPEAKER ON A STAND.
Do not attempt to mount the speaker on a stand without an assistant.
1. Mount the speaker on its stand prior to making any electrical
connections.
2. Check that the set screw in the speaker base is backed out
enough to clear the stand post.
3. After placement, verify that the stand post is fully seated in
the speaker base.
4. Tighten the set screw (by hand) to lock the speaker in place.
Failure to do so may result in injury or equipment damage.
Route and secure all cabling such that there are no tripping hazards.
Use gaffer’s tape or other retaining system liberally.
Any cabling which crosses a traffic lane must be covered or taped
down.
Add weight (i.e. sandbags) to the base of the stand for added
stability. In a windy outdoor location this is vitally important!

AC POWER DISTRIBUTION
It is very important to provide adequate AC power to each speaker in the
system. Performance of the PP1003A may be degraded if the AC voltage
drops more than five volts. The length of the run and the number of speakers
connected dictate the appropriate gauge AC cord (extension cord) to use.
Use the following table to establish the correct gauge AC cord to use.
CAUTION Never connect more than three PP1003A speakers to a single
AC cord run. If more than three speakers are used add additional AC cords
in parallel as needed.

SIGNAL DISTRIBUTION
Podium Pro Audio speakers can accept either balanced or unbalanced line
level sources and/or microphones.
•
A balanced interconnect is a three conductor system. Two inner
wires carry the audio signal differentially (opposite phase) and the
third wire is for ground reference and shielding only.
• An unbalanced interconnect is a two wire system wherein the center
conductor (aka “HOT”) carries the signal and the shield/ground
conductor is also a signal conductor.
The PP1003A will accept the two common interconnects. XLR and RCA.
XLR are balanced. RCA cables are always unbalanced. Balanced
interconnects provide superior noise immunity, especially for runs
over 10 feet. It is recommended that you use balanced in terconnects
whenever possible.
LINKING MULTIPLE SPEAKERS
See Figure 1 for control and connection locations.
To link (daisy-chain) multiple speakers, use an XLR interconnect from the
LINE OUT⑨ connector of the first speaker to the LINE IN⑧ connector of the
second speaker. The PP1003A employs a buffered, fully balanced LINE OUT
circuit. Therefore there is no practical limit to the number of speakers that
can be linked!
Tip: To use this feature effectively it is necessary to understand exactly what
LINE OUT is. It is the sum of the MIC IN⑦ and LINE IN⑧. This includes their
relative levels as set by the MIC LEVEL⑤ and LINE LEVEL⑥ controls.
Note that the MASTER GAIN②, TREBLE③ and BASS④ controls have no
effect on LINE OUT. This allows you to optimize each speaker as necessary
without altering the other linked speakers.

distortion occurs. Reduce the Volume with
the LEVEL control until the CLIP LED does
not light up any more, or occasionally lights up at signal peaks.
11. Power Supply Switch
12. Power Supply Input Connector: Use with power cord.
Make sure ALL of your equipment is completely OFF and lower ALL VOLUME, LEVEL & GAIN
controls before connecting the speaker.
Connections:
1. For the PP1003A you can connect a mixer or microphone directly into your speaker. To
connect a microphone use an XLR connector to connect to the MIC (6) input.
2. To connect a CD player, turntable or mixer use an XLR or RCA connector to connect to the
LINE IN (7) input. If connecting a powered mixer use the mixers line level signals only.
3. You can LINK additional speakers using the LINE OUT(8) connection. The amplifier on your
speaker will only power this speaker. If you LINK to additional speakers those speakers
must be self amplified.
4. Turn on your mixer/microphones or other signal source, then turn on your PP1003A, the
Power Indicator (9) will be lit. Now you can adjust your volume controls to a reasonable
level.
