WARNING

PROLONGED EXPOSURE TO HIGH SOUND LEVELS

Podium Pro Audio PP1203A 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. Two speakers can be safely stacked. The feet of the top speaker will engage cups designed into the top of the bottom speaker. Do not attempt to stack the PP1203A more than two high. More than two speakers create a tipping hazard.

Try to place the speakers between the microphone(s)

and the audience. This

will minimize acoustic feedback.

STAGE “FOLDBACK” MONITOR: Place the PP1203A 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 50lb. 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 PP1203A 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 PP1203A speakers to a single AC cord run. If more than three speakers are used add additional AC cords in parallel as needed.

Cord Gauge ONE PP1203A TWO PP1203A THREE PP1203A

up to 100’ up to 60’ up to 30’

up to 175’ up to 100’ up to 60’

up to 300’ up to 150’ up to 100’

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 PP1203A will accept the three most common interconnects. XLR, ¼” PHONE and RCA. XLR are balanced. ¼” PHONE cables can be balanced or unbalanced. RCA cables are always unbalanced. Balanced interconnects provide superior noise immunity, especially for runs over 10 feet. It is recommended that you

use balanced interconnects 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 OUT

connector of the first speaker to the LINE IN connector of the second speaker. The PP1203A 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 INPUT

and LINE IN

. This includes

their relative levels as set by the MIC LEVEL

and LINE LEVEL controls.

Note that the MASTER GAIN

, TREBLE

and BASS controls have no effect on LINE OUT. This allows you to optimize each speaker as necessary without altering the other linked speakers.

Podium Pro Audio

Functions:

1. MASTER: Control the output signal.

2. MIC LEVEL: Control the signal for MIC

when using a microphone.

3. LINE LEVEL: Control the signal for LINE

when using the line.

4. TREBLE: Rise or attenuate 12dB at 10KHz

frequency.

5. BASS: Rise or attenuate 12dB at 80Hz

frequency.

6. MIC INPUT: Use XLR or 1/4" jack connector balanced or unbalanced.

7. LINE IN: Use RCA orXLR connector balanced or unbalanced.

8. LINE OUT: Use for signal connection (Output) among other amplified speakers, when you input the signal to MIC or LINE IN.

9. Power Indicator

10. CLIP: The LED lights up when signal 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 PP1203A you can connect a mixer or microphone directly into your speaker. To connect a microphone use an XLR or ¼” jack 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 PP1203A, the Power Indicator (9) will be lit. Now you can adjust your volume controls to a reasonable

level.
