The RB-MM1 generates a mix for a telephone caller or remote presenter without that person’s own voice in the mix (thereby avoiding delay problems), for sending to a telephone hybrid or codec. Output level and cancellation null can both be controlled, and a switchable band pass filter is provided to condition the signal for the telephone hybrid. For stereo codecs, or conference calls, multiple RB-MM1 units can be used.
