70v Operation:The B series speaker can be installed in-ground or surface-mounted. In-ground installation is generally optimal since burying the speaker in-ground will enhance its resonance, providing a fuller audio experience. When mounted on a surface, please ensure the wiring is safely secured and does not become a trippinghazard. The optimal burial depth is 1 inch exposure from ground level for the bottom section. For in-ground installation, only burial-grade insulated speaker wires should be used. Conduit can be used alternatively in conjunction with standard speaker wires. Wire and conduit should be buried 4-6'' below ground.For connecting/extending speaker wires, we highly recommend using waterproof wire connector (ie. SPC-CN1).Alternately, silicon can be applied to the opening of standard wire nut to provide water protection. The B series is designed to be water-resistant, not waterproof. It is not designed to be protected against total water submersion, such as heavy flooding. With the raised downward facing profile, it's unlikely for the speaker to be submerged in water under normal rain and snow conditions. Please use caution and consider relocating the speaker when there is chance for heavy flood or snowfall.The system should be fully tested above surface before speakers and wires are buried.If sound is muddled or multiple speakers are not in sync, please check to ensure wire polarity is correct.To clean speaker, you can rinse with fresh water from directly above the speaker and wipe with a cloth. If need be, use mild detergent to remove dirt.1''B13 speaker can operate in both standard 8Ω mode and 70v mode. The 70v option, which is a constant voltage system, offers ease of installation for audio system with large quantities of loudspeakers and minimize the concern for power loss over long distance wire runs. However, there are also disadvantages to 70v system such as limitations to mono output and degradation of signal, especially in low frequencies, though often not noticeable except by discerning ears. 70v is often the preferred choice in large installations, such as many commercial projects, for both PA systems and background music systems. If you are unsure about 70v, please contact TIC or a trusted AV professional for consultation.If you are using B13 with a regular amplifier, please set dial to 8Ω and connect as normal.To operate in 70v mode. you must utilize a 70v amplifier. Simply set the dial to any of the wattage setting and connect the speaker to a 70v amplifier that has power output at least 20% greater than the summation of all speaker wattage settings within the sound system. The 20% headroom ensures optimal performance and longevity to both amplifier and speakers. The correct wattage setting will depend on your volume and sound sculpting requirement and the power output of your amplifier.67
