ลำโพง ยี่ห้อ JBL รุ่น Control 85M
The Control 85M Mushroom-Style Landscape Speaker is a two-way highly weather resistant speaker providing 360 degree coverage of the listening space. A highlighted mid-range presence cuts through in high ambient environments for especially clear paging and voice content while providing excellent full-range sound quality. Designed to be mounted on or in the ground, the Control 85M can be used in a wide variety of applications including hotels, casinos, pool areas, shopping malls, theme parks, sports venues, resorts, restaurants, hospitality and leisure venues, entranceways, and anywhere a high quality music and/ or paging speaker landscape speaker is required.
Its compact size allows the speaker to blend into landscaping and shrubbery, while its tough hunter green polyethylene enclosure resists abuse from lawn care equipment and the elements. The enclosure color extends throughout the material so the speaker will maintain color even when scraped or scratched.
The two part enclosure is designed to open with a twist for wiring and then close securely. The bottom base section of the enclosure can be pre-installed and then wired to the top speaker section of the enclosure. When assembled, the bottom base section becomes a fully isolated chamber, keeping the speaker and transformer (in the speaker section) highly isolated from the possibility of intruding moisture. Multiple locations on the bottom and sides are provided for the mounting of the exterior gland nut (installed by drilling a 22 mm (0.875 in, 7/8 in) diameter hole in the chosen location), and a second gland nut is positioned between the bottom base and the top speaker sections, to keep the speaker system highly weather tight.
Included gland nuts maintain a water-tight seal only when used with round-jacketed cable with outside diameter between 4.0 and 9.0 mm (0.16 and 0.35 inches).
All external hardware is stainless steel, and the powder-coated stainless steel grille resists rusting. The Control 85M can be secured to the ground via third-party ground stakes using the three attachment points that extend out from the bottom section of the speaker.
The 135 mm (5.25 in) diameter low-frequency driver features a Kapton former with 35.5 mm (1.4 in) voice coil for high power handling and superior long term reliability. The polypropylene cone and polyurethane surround provide high strength and superior moisture resistance. The 19 mm (0.75 in) high frequency driver utilizes a polyetherimide dome, providing high rigidity, strength, and high temperature resistance. The high slope crossover provides natural sonic character and SonicGuard™ protected HF driver ensures long-term reliability from occasional overdriving.
In addition, the speaker contains a high-quality 30 Watt multi-tap transformer for use on 70V or 100V distributed loudspeaker lines, and is switchable for 8 ohm voice-coil direct operation. The speaker handles 80 Watts Continuous Pink Noise (160W Program, 320W Peak) in the 8 ohm mode.
The Control 85M is UL certified, per UL1480.
