In many system installations, you can replace an entire rack of pro audio gear—with a single Pema™. Pema™ with it’s new sleek look, is a Protea-Equipped Media Amplifier—either 4 or 8-channel at 250 Watts or 125 Watts per channel. Pema is a matrix mixer—all Pema models have a full 8-in x 8-out matrix mixer, where any input can be assigned to any output or outputs. Pema is a digital signal processor. In addition to the full Protea™ suite of DSP settings, we have added four new features to Pema—gain sharing automatic microphone mixing, an automatic feedback suppressor, ambient noise detection and adjustment and a real-time clock with an event scheduler. Pema features Ashly’s energy efficient Class-D amplifier topology with a switching power supply—and is over 80% energy efficient out of the box. Maximize the energy efficiency of your audio system by using the event scheduler to either put the Pema in stand-by mode or turn it off completely. Pema is offered in separate Low-Z, 25V, 70V, or 100V constant voltage models. Pema is also offered with 240V line voltage in either Low-Z or 100V output for International customers.
