Auto Answer Coupler
Product Description
This Auto Answer Audio Coupler was originally designed by Mike Rabey, a nationally known radio engineer from Indianapolis, Indiana. It was
marketed as the Indy Audio TC-1 for many years and has been in use by radio stations for over ten years. In 1999, Mike Rabey decided that
he no longer had the time to manufacture the couplers
and TRZ Communications, which was one of his biggest customers, suggested that they take over the manufacturing if Mike would agree to continue
to provide technical support. Mike agreed and TRZ
began manufacturing the couplers in July of 1999. This coupler is a favorite of radio engineers, or anyone who needs to access audio or
transmit audio via telephone line, for several important
reasons. It needs no power supply. The unit is powered by the phone line. It comes in a very small package so it fits easily into a
crowded studio or phone room. It focuses on a few basic
operations, so you aren't paying for features you don't need. It's rugged and reliable and comes with a one year guarantee. (In fact, after the
one year is over, TRZ will generally repair any
damaged couplers for just the shipping and handling costs!) Finally, it is priced right. It is the least expensive auto answer audio
coupler on the market. So, if you are putting together a
small radio network or just need a listen line for an consultant or member of management to dial into the station. This is the coupler for you!
