The Azden brand goes along with Rode and Sennheiser, but they seem to have filled a gap that has been left open for awhile by the mainstream brands.  Juiced Link and Beachtek have both produced small sound mixers, that leave some to be desired, but Azden has housed their own in a more sophisticated, small box that operates in the same fashion, but gives the user more control over their levels, as well as includes a jack for headphones in addition to the dual XLR inputs, and the L and R channel level controls. Azden also covers a FMX 42/42a 4-channel portable mixer, which offers 4 XLR inputs and 2 XLR outputs plus a mini plug output, adjustable input level monitor level, and adds a 10-pin  and mini plug camera return. These sound mixers run from $400 for the smaller dual channel mixer to $840 for the larger 4 channel mixers. Another unique product is the Azden dual receiver/transmitter kit. Running at $750, this price is highly competitive with buying two Azden or Sennheiser kits at around $599 each.  This dual receiver allows you to mic two people and run separate channels into one receiver, rather than using two receivers and two transmitters.
