The SLA are 2RU power amplifiers and includes 9 models, both dual and 4 channel. The SLA series provides a broad choice of power output extending to 2ohms 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; the parallel (mono) mode; and in the bridge mode. The SLA series power amplifiers employs 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.
