3. Продукт бүтүп калдыview

The Bogen AFI-8B loudspeaker is engineered for high-fidelity sound reproduction in demanding environments. Key features and components include:

  • Айдоочу кошумча:
    • Төмөн жыштык: One Apogee 15" (381mm) neodymium magnet cone-type driver. This driver is treated with a waterproofing compound for moisture resistance and long-term stability of cone resonance and mass parameters. It also features Ferrofluid for enhanced power handling, reduced distortion, and controlled short-term impedance rise.
    • Жогорку жыштык: One Apogee 3" (76mm) voice coil, 2" (51mm) exit horn-loaded compression driver. This driver is also treated with Ferrofluid for improved power handling, lower distortion, and stable impedance.
  • Киргизүү туташтыргычтары: Barrier strip, screw type #8, for secure and reliable audio connections.
  • туткалары: Two integrated handles (one top, one bottom) designed as part of the enclosure for easy transport and positioning, ensuring no moving parts.
  • Тор: Highly durable, quality finish on perforated steel, providing protection for the drivers.
  • Тактоо аппаратурасы: Fourteen rigging points are provided for versatile installation. There are four points each on the top and bottom, and two each on both sides and the rear. All points are backed with 16-gauge steel and can accommodate 3/8"-16 or M10 thread types.
  • Бүтүрүү: Textured high-strength black epoxy paint for durability and a professional appearance.
  • Корпусунун түрү: 30° trapezoidal, optimally-vented bass design for enhanced low-frequency performance.
  • Кабинеттин курулушу: Multi-ply hardwood for robust structural integrity.

4. Орнотуу

4.1 Орнотуу жана орнотуу

The AFI-8B loudspeaker features a 30° trapezoidal enclosure, allowing for array configurations. Its dispersion pattern is H: 60° x V: 40°. Consider this when determining placement to achieve optimal sound coverage.

For permanent installations, utilize the fourteen rigging points. Ensure that the mounting surface and hardware can safely support the loudspeaker's weight (77 lb). Use appropriate 3/8"-16 or M10 threaded hardware. Always consult with a qualified installer for complex rigging setups.

4.2 Электр байланыштары

The AFI-8B is a bi-amped loudspeaker, meaning separate amplifier channels are required for the low-frequency and high-frequency drivers. Connect your amplifiers to the barrier strip, screw-type #8 input connectors on the loudspeaker.

  • Ensure all power to amplifiers and other audio equipment is turned OFF before making connections.
  • Use appropriate gauge speaker wire for the distance and power requirements.
  • Observe correct polarity (+ and -) for all connections to prevent phase issues.
  • Сунушталган кроссовер: For full technical data on DSP-based processors and crossover settings, contact Apogee Sound. Proper crossover settings are crucial for optimal bi-amped performance and driver protection.

5. Иштөө нускамалары

Once the loudspeaker is properly installed and connected, follow these guidelines for operation:

  • Күйгүзүү ырааттуулугу: Always power on your audio source and mixer first, then your amplifiers. When powering off, reverse this sequence: amplifiers off first, then mixer and source. This prevents transient pops that can damage speakers.
  • Ampкөтөргүч дал келүү: Сиздин камсыз кылуу amplifiers are appropriately matched to the loudspeaker's power handling capabilities. The AFI-8B has a maximum power handling of 400W continuous and 1600W peak. The nominal impedance for each driver is 8 ohms.
  • Жеңиш Сtaging: коюу amplifier gains and mixer levels carefully to avoid clipping (distortion) which can damage the drivers. Monitor your audio signal for any signs of distortion.
  • Monitoring Sound Levels: The loudspeaker has a maximum SPL of 125dB continuous and 131dB peak. Prolonged exposure to high sound pressure levels can cause hearing damage. Use hearing protection when operating at high volumes.
  • Жыштык жообу: The loudspeaker provides a frequency response of 46Hz to 20kHz (±3dB), offering a wide range for various audio applications.

6. Техникалык тейлөө

Regular maintenance helps ensure the longevity and optimal performance of your AFI-8B loudspeaker.

  • Тазалоо: Clean the cabinet and grille with a soft, dry cloth. Do not use abrasive cleaners, solvents, or excessive moisture, as these can damage the finish or internal components.
  • Текшерүү: Periodically inspect all connections (speaker cables, rigging hardware) for signs of wear, corrosion, or looseness. Tighten any loose connections.
  • Курчап турган чөйрө: Store and operate the loudspeaker in a stable environment, away from extreme temperatures, humidity, and direct sunlight.
  • Кесиптик кызмат: If you suspect any internal issues or damage, do not attempt to repair the unit yourself. Refer all servicing to qualified service personnel.
