The LA100B is an encapsulated and electronically protected power amplifier module. The circuit uses components of the highest quality and is assembled using predominantly surface mount components. The innovative design results in a very rugged module that also exhibits excellent sonic qualities.

The LA range of amplifiers are built into a bespoke anodised extrusion with ample heatsinking due to the finned design, allowing you to fit the modules in a huge range of applications.

They can used on 4 or 8 ohms, have a wide range frequency response, short circuit protection and output S,O,A, protection and are equally at home in both audio and industrial applications.
