 The Ashly Pema Powered 4125.70 Processor is a powerful and flexible all-in-one solution for routing and amplifying audio in multi-zone installations, houses-of-worship, retail spaces, restaurants, bars and much more. The Pema series offers extensive DSP control, making it virtual integrated PA solution "in a box". Simply connect the audio input sources and speakers and easily mix and route audio signal, control compression, gate, EQ, ducker parameters and much more.


There are 8 inputs and 8 outputs via Euroblock I/O and 8 built-in mic preamplifiers with phantom power. Both stereo and summed mono outputs are supplied and a dedicated telephone / PBX input is also standard. Pristine audio throughput is ensured with 24-bit A/D~D/A audio resolution and 96kHz or 48kHz sample rates supported. A wide array of control includes automatic feedback suppression, ambient noise control, adjustable HP and LP filters and more.
