Installation and setup video by Keith Vincent

This USB microphone system is designed for the Eclipse user in mind! With this system, you can record the audio from the 4 included microphones onto 4 separate channels in Eclipse. When you playback the audio, you can listen to all of the channels at the same time, or one at a time.

There are four 3.5mm (1/8") stereo microphone input jacks on the 4 Andrea soundcards. The system includes one mic per soundcard for a total of 4 mics, but it can be expanded to 2 microphones per soundcard if desired for a total of 8 microphones recording onto 4 channels in Eclipse.

The setup is simplicity itself - load the driver on your computer (supplied), plug the microphones into the USB hub (you can plug in all 4 microphones, but you can use fewer if you want to) and plug the hub into the computer.

Some older computer's USB ports may not supply enough power for the USB hub, so we also supply an A/C adapter fir the hub. Again, the vast majority of computers today will supply enough power from one USB port without the need for the A/C adapter.

There are NO batteries anywhere in this system!

Each soundcard has a headphone jack for live monitoring. You can adjust the recording level and monitoring level of each mic (or mic pair if you use stereo mics) individually as needed. Need help? No problem - we can remote into your computer and set this up for you if needed.

The audio quality of the system is our best! It uses the same audio engine as our popular USB HG Model 6+ microphone. It offer 30dB of microphone boost on each channel.

Wireless Microphone information

Audio-Technica's System 10 is digital high-fidelity wireless system designed to provide performing musicians and presenters with advanced 24-bit operation, easy setup and clear, natural sound quality. Operating in the 2.4 GHz range, far from TV and DTV interference, System 10 offers extremely easy operation and instantaneous channel selection. Up to eight channels may be used together without any frequency coordination problems or group selection issues. System 10 receivers and transmitters offer an easy-to-read digital ID display. 

System 10 wireless ensures clear communications by providing three levels of diversity assurance: frequency, time, and space. Frequency Diversity sends the signal on two dynamically allocated frequencies for interference-free communication. Time Diversity sends the signal in multiple time slots to maximize immunity to multipath interference. Finally, Space Diversity uses two antennas on each transmitter and receiver to maximize signal integrity. 

Featuring stackable, contemporary styling, System 10 is available in multiple system configurations, with handheld vocal microphone/transmitters and UniPak body-pack transmitters designed for use with lavalier, headworn and instrument microphones as well as electric guitars. Each configuration includes the ATW-R1100 receiver and either body-pack transmitter or handheld microphone/ transmitter. The ATW-R1100 is digital receiver offering volume control along with AF Peak and Pair indicator lights.
