TAG Heuer HL551-10 Ampifier Box for Headset

One amplifier box is required for every headset used in a timing / communications application. They can be setup on wire pairs dedicated to communication or share wiring with the timing equipment. Two sets of banana jack connections allow for fast and easy integration into on hill wiring. A twist lock connector mates with the headset cord. The amplifier box is only on and consuming power when a headset is connected to it. Each amp box is internally powered by one 9 volt battery.
