Introduction to the BN9

The BN9 is a high gain miniature amplifier with all sorts of possible applications, limited only by your imagination. Its small size and economical price make it a useful addition to many projects and re- pairs.

The BN9 has an amplification gain factor of 3000 with as much as 2 1/2 watts of audio power output. It can also be configured for a gain of only 50 to make it versatile for any number of applications. While high gain may be used for projects such as ‘super sleuthing, low gain can be used for Walk- man boosting and telephone boosting.

This kit is called the super sleuth due to the very high gain it can be configured for. In this mode it can be combined with a sensitive microphone and parabolic dish to pick up sounds from hundreds of feet away such as:

•Listening to birds and wildlife from a distance.

•Keeping an ear on the kids in the back yard.

•Building up a nice hearing aid for folks who can’t afford or don’t need a commercial hearing aid.

•To hear what is happening on the field at sporting events.
