The DigiWave DWS-INT-2-400-ALK wireless intercom system provides contactless communication for one speaker and up to ten listeners within a 600-foot range. The system includes one DLT 400 full-duplex transceiver with headset microphone, ten listen-only receivers with earphones and batteries (alkaline), one power supply pack, and a system carry case. Employing the same DSS frequency-hopping technology found in cell phones, the system offers an interference-free and highly secure method of communication. Using DSS, the DigiWave 400 transmits in the 2.4 GHz ISM band rapidly and randomly switching frequencies resulting in a signal that dodges common wireless anomalies and makes it extremely difficult for third parties to listen in. The single muff on-ear headset connects to the transceiver's 3.5mm jack and features an adjustable swivel mic boom. There is also an external microphone input to accommodate a preferred microphone or headset. The DWS-INT-2-400-ALK supports up to six simultaneous talkers and unlimited listeners (additional receivers/transceivers sold separately) with configurability for two-way or one-way communication giving you the flexibility to grow and cover multiple applications.
