The Bogen Nyquist NQ-S1810WBC VoIP wall baffle combo speaker unit provides the same superior features as the NQ-S1810WT-G3 with the addition of a red LED messaging display and programmable flasher. There is no need for external amplifiers, traditional intercom wiring, or transformer taps to manually set or adjust. Connect the speakers via Cat5 to a PoE capable network switch (or add a PoE injector for a non-PoE switch), add the station into the system and it is ready to operate. The message display can show a clock with date and time (seconds are optional), or user-programmable messaging for standard or emergency announcements. The flasher is completely programmable for color, duty cycle, and duration to differentiate alert types, and can be triggered independent of the message display. 

As one would expect from Bogen, the HD audio quality is superb, with excellent incoming and outgoing intelligibility. Many two-way speakers use the speakers itself as the microphone, resulting in poor talkback audio quality. The Nyquist Series VoIP Wall Baffle speakers use a separate high-performance MEMS microphone to achieve superior talkback audio.
