Wireless monitor systems are a terrific alternative to cumbersome floor monitor wedges, facilitating greater freedom of movement while enabling one to hear everything in either high fidelity mono or stereo. That is what the EM900 In-Ear Personal Monitor System is all about. Ideal for both on stage use and rehearsals, performers can use as many as 16 complete EM900 systems simultaneously on stage and any number of EM901 stereo receivers on the same frequency. Take your live performance to the next level with a wireless monitor system from Carvin!
