The microphone has very selective directionality - we use the term 'hyper-cardioid' to describe the directional characteristics of the unit. Precision engineered to the latest technical specifications and using the state-of-the-art electronic components, the Yukon DSAS allows you to listen to sounds at a distance up to 300 feet (100 meters). Selective Resonation Design, an exclusive DSAS feature, captures and delivers the sounds emanating from the subject under observation while rejecting sound from outside the selected area.

Directional Antennae allows the DSAS to reduce background and wind noise without the need for a bulky parabolic dish. The sound receiver is removable (demountable). The electrical power for the DSAS is provided by a commonly available 3-volt lithium battery, which will deliver up to 300 hours of operation before replacement is required. Audio output level is adjusted by digital push buttons.
The DSAS can be tripod mounted or easily attached to camcorders, binoculars, spotting scopes and night vision devices. It incorporates a special ? inch pullout junction that allows the unit to be attached to optical devices.

The DSAS extends the capabilities of any optical device - you can not only observe an object but also listen to sound emanating from it. Recording devices can be attached via a standard audio jack. The unit comes completely equipped with headset, batteries, user's manual and a padded corduroy carrying case.

The professional qualities of the DSAS allows it to be employed by sound engineers and journalists while its low cost and small size makes it attractive for very wide variety of users - search and rescue services, security personnel, ornithologists and nature-lovers.
