Mobile Phone Headsets Sony

The Sonifex RB-MM1 is a unit for generating a suitable mix to send to a telephone hybrid or codec. A stereo output is taken from a mixer, together with a post fader output from the mono telephone fader on the mixer. The caller audio is removed from the station output so that it can be sent to the telephone line via the hybrid. The analog audio inputs and outputs are via Neutrik XLR connectors. The output level to the TBU can be adjusted using a rear panel pre-set potentiometer. To control the cancellation null (the amount of the telephone channel which is subtracted from the mixer output signal), 2 multi-turn potentiometers are provided, one for the LF null and the other for the full-band

Sound mixers often find themselves in very high noise environments such as helicopters, raceways, firing ranges, rock concerts, etc., left with ringing ears and wondering what was actually being recorded. Providing extreme isolation from outside noise and using Sony MDR-7506 drivers with special baffling, the Remote Audio HN-7506 allows accurate, full-range monitoring in loud environments and adds a high degree of protection from hearing damage while giving the user the familiar sound of the industry standard Sony headphones.
