LD1.0
The Opus Technologies LD1.0 is a small model of single output magnetic loop amplifier line. The 5-sides continuous output current and all necessary functionalities (AGC, MLC, etc.) ensure installation in spaces of up to 250 m².
THE LD1.0 incorporates high-efficient Class D amplifier that guarantees maximum power for small and mid-size areas. The device has 3 inputs: 2 switchable line or microphone and a priority 100 V.
priority 100 V.
The amplifier includes fault synthesis that continuously controls the loop and the amplifier. The information is visible on the front panel and can be deported with a simple touch.
The LD1.0 proven technology and manufacturing quality provide 5 years of warranty.
