Opus Technologies LD1.0

The Opus Technologies LD1.0 is the small model of the single output magnetic loop amplifier range. Continuous 5Arms output current capable and all the necessary functionalities (AGC, MLC, etc.) ensure the installation of 250m² room.

The LD1.0 incorporate a hight-efficieny class D amplifier that guarantees maximum power for small and medium-sized rooms. The device have 3 inputs: 2 switchable line or microphone and a priority 100V.

The amplifier incorporates a fault synthesis that controls continuously the loop and the amplifier. The information is visible on the front and can be deported thanks to a simple contact.

The LD1.0 proven technology and quality of manufacturing allow us to offer a 5 years warranty.
