Revolabs 02-HDDUAL-NM Overview

The Revolabs 02-HDDUAL-NM HD Dual-Channel Wireless Microphone System with 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.

Fabulous quality

This is the tool that enabled me to hold live presentations and at the same time make them available remotely via GoTo Meeting, and have excellent audio in both. I'm using lapel and XLR mikes to get the sound amplified by the in-room speaker system and transmit remote.

question

pairing microphones with base station?
Asked by: Anonymous
Microphones in new systems must be paired to the Base Station with each microphone assigned to a unique channel on the Base Station. This is done with the Mute button. Here is a link to the manual: http://bit.ly/1zUXRnM
