Telephone Line Coupler

The TC10 provides a low-loss audio interface to a telephone line. The line-powered unit is compatible with all analogue direct exchange lines, and includes both an LED indication of incoming calls and a ringer with mute switch. Although the unit is commonly used with an earpiece amplifier to receive an audio feed by telephone from the studio, it can also be used to couple the studio output to the line.
