This amplifier is designed for use with the Trophy DES Rally helmets & Trophy DES practice headsets. The amplifier offers great value for money for the amatuer/club-level rally competitor.
It has a switch to power the unit on/off & a single dial to adjust the volume for both channels simultaneously.
Powered by a 9-volt battery (not supplied) or can be connected to the car battery by using the 12-volt power supply (optional extra).
