5. Setup
5.1 Unpacking and Inspection
Carefully remove the speaker from its packaging. Inspect the unit for any signs of damage during transit. If damage is found, contact your dealer immediately.
5.2 Placement Options
The multicomp PRO speaker offers flexible placement:
- Floor Mount: Place the speaker directly on the floor using its integrated rubber isolating feet to dampen vibrations.
- Pole Mount: Utilize the 1-3/8” (35mm) diameter pole mount socket on the bottom of the speaker to elevate it on a compatible speaker stand.

5.3 Connecting to an Amplifier
This is a passive speaker and requires an external power amplifier. Ensure your amplifier is capable of driving an 8 Ohm load and provides sufficient power (up to 240W) without clipping.
- Connect one end of a speaker cable (included) to either the SpeakON or 1/4-inch input on the rear of the speaker.
- Connect the other end of the speaker cable to the corresponding output on your power amplifier.
- For daisy-chaining multiple speakers, use the 1/4-inch parallel output to connect to the input of another passive speaker. Ensure the total impedance load on your amplifier channel is within its safe operating limits (e.g., two 8 Ohm speakers in parallel result in a 4 Ohm load).

6. Operating Instructions
- Ensure all connections between the speaker and the amplifier are secure.
- Turn on your power amplifier.
- Start with the amplifier's volume at its lowest setting.
- Begin playing audio through your connected source (e.g., mixer, media player).
- Gradually increase the amplifier's volume to the desired listening level. Monitor for any distortion or clipping from the amplifier, and reduce volume if necessary.
- Adjust the tone controls on your amplifier or mixer to achieve the desired sound quality.
7. Maintenance
- Cleaning: Use a soft, dry cloth to clean the exterior of the speaker. Do not use liquid cleaners or solvents.
- Storage: When not in use for extended periods, store the speaker in a dry, cool environment, away from direct sunlight and extreme temperatures.
- Inspection: Periodically check all cables and connections for wear or damage. Replace any damaged components immediately.
- Grille: Ensure the metal grille is free from dents or obstructions that could affect sound quality or damage the drivers.
8. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| No sound output | Loose cable connections; Amplifier off or muted; Incorrect input selection on amplifier. | Check all speaker cable connections; Ensure amplifier is powered on and not muted; Verify correct input is selected on the amplifier. |
| Distorted sound | Amplifier volume too high (clipping); Speaker overloaded; Damaged speaker driver. | Reduce amplifier volume; Ensure amplifier power matches speaker rating; If distortion persists, contact service personnel. |
| Weak or low volume | Low input signal; Incorrect impedance matching. | Increase source volume; Ensure amplifier output impedance matches speaker impedance (8 Ohms). |
