A great companion to MacSpeech Dictate, the Samson AirLine 77 is the first UHF wireless microphone certified for use with MacSpeech Dictate - and it lets you dictate up to 300 feet from your Mac.
This is the microphone of choice for our CEO and Founder - Andy Taylor. Andy regularly uses the AirLine 77 for live demonstrations of MacSpeech Dictate.
AirLine 77 is Samson’s newest version of the AirLine series that features the first micro-technology transmitters in the industry. Traditional wireless systems consist of belt-packs and wires that can hinder the user. With AirLine, you get a true wireless system because there are no belt-packs and no cables, allowing the user complete freedom.
The Airline headset fits comfortable behind the head, allowing the transmitter to be attached directly to the headband, and out of the way and completely unobtrusive. While being comfortable and secure, the headset will stay in place even during fitness and exercise routines.
The AirLine transmitter operates on inexpensive and lightweight AAA batteries that offer 14 hours of operation on a single battery.
CR77 Receiver
The heart of Airline 77 is the new CR77 Receiver. This true-diversity half-rack unit with PLL frequency control works with all of the Airline transmitters. Rugged, durable and crystal clear with incredible range. UHF (Ultra High Frequency) means clearer frequencies with less interference.
Includes USB Adaptor.
