The Ashly Pema 4250 Media Amplifier is a Protēa-equipped media amplifier with 4 channels with 250W per channel.
In many system installations, you can replace an entire rack of pro audio gear with a single Pêma™. Pêma is a matrix mixer with a full 8-in x 8-out matrix mixer, (any input can be assigned to any output or outputs). Pêma is a digital signal processor with the full Protēa™ suite of DSP settings. Then we added gain sharing automatic microphone mixing, an automatic feedback suppressor, ambient noise detection and adjustment and a real-time clock with an event scheduler.
Pêma features Ashly’s energy efficient Class-D amplifier topology with a switching power supply—and is over 80% energy efficient out of the box.
