Very impressed with the range and audio quality of the D2.4 system, so I bought an extra receiver. This lets our band get two IEM mixes from just one D2.4 transmitter. Road tested this at a venue that's given trouble with 2.4G systems before - lots of Wifi congestion at most venues we play these days - and the results were impressive. Clear audio and no drop outs, happy days!
Connect IEM mix 1 to Left channel, IEM mix 2 to Right channel.
Set transmitter to Stereo and receivers to Mixed.
Pan one receiver hard left to get IEM mix 1, and pan the second hard right to get IEM mix 2.
