The SLA are 2RU power amplifers and include 9 models, both dual and 4 channel. The SLA Series provides a broad choice of power output extending to 2Ω operation so you can select a model that will ideally match the power requirements for your application. For even further flexibility all models can operate in 3 modes: dual channel mode; parallel (mono) mode; and bridge mode. The SLA Series power amplifers employ a large number of matched complementary devices in parallel having linear transfer characteristic for low distortion and high SOA guaranteeing safe operation at elevated power levels.
