Q&A Section
- Q: Can it be used outdoors?
A: No - it is rated for indoor use only, with an operating temperature of 0-40 degreesC. It is not water‑resistant.
- Q: What is the best tap to use in a corridor?
A: Use the lower power taps (7.5 W or 3.75 W) for corridors to avoid overloading the system and to achieve a consistent level across zones.
- Q: Are replacement cables or terminals provided?
A: It uses colour‑coded screw terminals; only the supplied screws and standard cable are included. Any additional wiring must meet 100 V system standards.
- Q: How is polarity maintained when installing multiple units?
A: All speakers must be wired with consistent polarity to avoid phase cancellation. White wire is common; coloured wires match tap selections.
- Q: What maintenance is required?
A: Only occasional dusting with a soft, dry cloth. Never use water or chemicals. Ensure it remains free of moisture or extreme heat.
