The tiny TOOLS TT-1 is more than just an ordinary telephone line coupler. The TT-1 is a rack-able compact telephone line powered auto-answer and auto-disconnect hybrid. The TT-1 utilizes dual-hybrid transformers providing full duplex audio at a plain old coupler price. We provide a rear panel multi-turn hybrid NULL trimmer to allow the user to achieve 20 plus db separation figures. TT-1 features include: Front panel Line Seize button; call Drop button; Auto-Answer/Monitor switch; Audio Mute switch; Off-Hook and Ring indicators. The rear panel is equipped with a RJ-11 jack for the telephone line and a second loop-thru RJ-11 that may be configured to disconnect attached devices when the TT-1 goes off-hook. 3.5mm and screw terminals are provided for balanced send and caller audio; remote dry contact seize and drop switches and SPDT off-hook dry relay contacts. The TT-1 may be set on a desktop, mounted on a wall or up to four units mounted on the RA-1 rackmount shelf.
