รายละเอียด

QSC AC-C4T-nb Full range ceiling mount loudspeaker 4.5″ (no back can)

ลำโพงติดฝ้าเพดาน QSC AC-C4T-nb แบบ no back can, ขนาดดอกลำโพง 4.5 นิ้ว Full-range, 140° conical, ทนกำลังขับสูงสุด 6 วัตต์, Transformer taps 70 V 6, 3, 1.5, 0.75 วัตต์, 100V 6, 3, 1.5 วัตต์, Effective frequency range 62 Hz – 18 kHz

The QSC AcousticCoverage™ Series “no back can” models (nb) are full-range 4.5 and 8 inch ceiling-mounted loudspeakers. Each comes with a 70/100V transformer and is suitable for a wide variety of audio/ video conferencing reinforcement, voice paging and background music applications.

The 6-watt low-saturation, low-loss 70/100V transformers have color coded bare wire terminations to avoid the cost of rotary selectors. For enhanced performance and speedy installs, implement model-specific advanced voicing through QSC Intrinsic Correction. QSC Intrinsic Correction™ is available in the Q-SYS™ Platform and in CXD Series amplifiers.

The AC-C4T-nb and AC-C8T-nb come in QSC standard white (RAL 9010) to match complementing QSC product families. UV inhibitors in the pigment prevent discoloration over time. The loudspeakers may also be painted to match any décor. For your system integration needs, complete EASE, CF2, CAD, and BIM files are available for download at QSC.com.

Features:

  • High quality 4.5” full-range transducer provides exceptional clarity through the critical voice range.
  • Ported baffle for increased low frequency extension down to 70 Hz.
  • Low-saturation 70V/100V transformers with 8-ohm bypass.
  • 4-pole Euroblock connector for easy system wiring.
