Revolabs 02-HDDUAL-NM HD Dual-Channel Wireless Microphone System with No Mic (1.9 GHz)The Revolabs02-HDDUAL-NM HD Dual-Channel Wireless Microphone Systemwith No Mic provides clear, reliable, untethered communications; ideal for recording, conferencing, VoIP, sound reinforcement, and more. The system includes a dual-channel base station, a dual-channel charger base for HD mics, and a power adapter. A microphone is not included, allowing you to select the HD mic or adapter/transmitter that best suits your needs. The system features a frequency response of 50 Hz to 14 kHz and provides high-quality sound using 1.9 GHz DECT technology to broadcast clear, intelligible speech and vocals at a range up to 150′.
By using MC/TDMA/TDD radio transmissions both to and from your microphone, the system is able to co-exist with wireless 802.11 networks and GSM cellphones without interference. It also includes digital encryption technology for secure communications. The transmitter has analog 3.5mm input and output connectors, which can be switched between mic and line level operation, and also has the ability for both inputs and outputs to be mixed to a single channel.
Because the system is full-duplex, the input connections provide the ability to hear program audio using a 2.5mm earpiece attached to the HD wearable microphone (available separately). Depending on the application, it is possible to feed a single audio feed back to each earpiece allowing for translation, personal hearing assistance, or other services to be incorporated into an application.
The 02-HDDUAL-NM HD includes a base, charger, and power adapter. A variety of compatible HD microphones are available separately along with adapter/transmitters that allow you to use a wide variety of third-party mics.
