Most wireless headset or earset microphones with an XLR out connection are supported for use with HDL310 systems and Voice Amplification Mode.

 Required before you start:

A balanced XLR to unbalanced 3.5mm TRS adapter cable is required to connect to the auxiliary ports on the HDL310 connect module. This cable is purchased separately. Please see your audiovisual reseller to purchase this cable.
