Input Selection
The 3.5mm Audio jack on the front of the transmitter can accept line-level audio input or a
microphone. The MUSIC/MIC switch on the back is used to select the type of source being used.
Music: Select this option if you are using a line-level audio signal (which could be musical,
spoken word, etc.).
0dB: Use this switch position if you are using a normal microphone.
20dB: Use this switch position if you are using a mic with a highly sensitive pickup.
Wireless Channels and Range
This system uses a 2.4GHz WiFi carrier to transmit the audio information from the transmitter to
the receiver/amplifier. Because the 2.4GHz WiFi band is rather crowded with wireless devices of
all kinds, this system provides 30 different WiFi channels, more than twice the number offered by
Wireless-N routers.
If there are other WiFi channels in use within range of this system there is the potential for
interference. To reduce this chance of interference, we recommend changing to channels 21-30
using the CH+ and CH- buttons on the front of the transmitter. The receiver will automatically
change the channel to match that of its paired transmitter.
If there are other WiFi or 2.4GHz wireless devices in use in the area, this transmitter and receiver
have an effective range in clear air of up to about 55 feet (17 meters). If there are no other 2.4GHz
transmissions in the area, the clear air range is increased to up to about 98 feet (30 meters). The
presence of walls and floors within a home, as well as the presence of other electrical
transmissions and emissions, will reduce the range somewhat.
One-to-One Pairing
The following procedure is used to pair a single receiver/amplifier with a single transmitter.
1. Ensure that both the receiver and transmitter are powered on and that they are well within
wireless range listed above.
2. Press and hold the CH+ buttons on both the transmitter and receiver for about 3-5 seconds,
until the status LEDs flash.
3. Release both CH+ buttons at the same time.
4. Power off both the transmitter and receiver, wait for about 30 seconds, then power them both
on. The two devices are now paired.
5. The status LEDs will be off when the transmitter and receiver are properly paired.
Because the system features 30 wireless channels, you can theoretically have up to 30 sets of
transmitter/receiver pairs in simultaneous operation. A practical application for using multiple
pairs of receivers and transmitters is to wirelessly connect your 5.1 home theater speaker
system. One set can be used to drive the front speakers, the second set can drive the rear
surround speakers, and a third set can be used to feed the audio signal to the subwoofer.
