In order to broadcast stereo to your in-ears, U45D uses two XLR connectors. The main Transmitter module (L) connects to the Left output on your mixer, and includes all functional controls and indicators. The Stereo Expansion Module (R) is pre-connected to the Transmitter module, and plugs into the Right output on the mixer. Both units can also be connected to unbalanced ¼” TS aux outputs using the included adapters.
U45D features four selectable output modes: STEREO, L , R, and MIX. For full STEREO mode, pan the left channel output on the mixer hard left, and the right channel hard right. L (left) mode sends the left channel to both earphones; R (right) mode sends the right channel to both earphones. “MIX” sums the left and right channels to mono and sends the mono channel to both ears. Only connecting the L transmitter module to the soundboard output also has the effect of sending a mono signal to both ears.
U45D offers six fixed-frequency channels. The channel with the strongest signal can be automatically detected and selected by pressing and holding the channel button on the Receiver for 3 seconds to enter Channel Scan mode. The Receiver’s channel LED will flash during scanning and then will stay on the optimal wireless channel. Set the Transmitter to the same channel to pair your system.
5.8 GHz is a more reliable choice for wireless connection stability. Signal interference is more likely on the 2.4 GHz band, since more devices use that frequency. The U45D signal can travel up to 100 ft; actual range depends on RF signal absorption, reflection and interference. Enjoy an audiophile monitoring experience with 24-bit / 41.6 kHz audio, wide 20 Hz – 20 kHz frequency response, a dynamic range of 110 dB, signal-to-noise ratio of 110 dB and less than 5 ms latency. The U45D system offers 5 hours of battery life to get you through any gig!
You can send the same signal from one U45D stereo Transmitter to multiple U45D Receivers, as long as they are all set to the same channel. Multiple U45D systems can operate with one mixer, as long as you have enough output channels (with stereo pairs) to send separate mixes to each Receiver.
