The new Qt® Active Emitter is a single-source Emitter capable of both sound masking and simultaneous clear reproduction of paging and music signals. It provides higher SPL and a broader frequency range than previous direct field Emitter offerings in a small, powerful speaker that’s virtually invisible once deployed in finished or open structure ceilings.
- Active electronics power the speaker
- Ported enclosure design allows lower frequency extension down to 125 Hz octave band for sound masking and 115 Hz for paging and music
- 17 dB louder than previous direct field emitter offerings
- Plenum-rated, UL-listed, and complies with UL 2043
- Delivers four uncorrelated audio channels to reduce phasing/comb-filtering
- Comes standard with a slip-ring mount for acoustical tile mounting
- Rear DIP switches reduce volume by 4.5 dB in 1.5 dB increments, if needed
- Compatible with the Qt 300 and Qt 600 control modules
- Control via web-based management from any device
