Opus Technologies LD1.0 Rackable Loop Amplifier

£556.02

LD1.0
LD1.0

The Opus Technologies LD1.0 is a superb Rackable Loop Amplifier, in addition to the smallest model of the single output magnetic Loop Amplifier range. A continuous output current, and all the necessary functionalities (AGC, MLC, etc.) ensure the seamless installation of rooms measuring up to 250m².

The LD1.0 incorporates a highly efficient class-D Amplifier that guarantees maximum power for small to medium-sized rooms. The device itself contains 3 inputs: 2 switchable line or microphone and a priority 100V. A fault synthesis is also included, allowing control of the Loop & Amplifier. It’s important to note, that the information displayed on the front panel can be deported thanks to a simple contact.
