Pema

Pema Series

Multi-Channel Amplifiers

PEMA™ sets a new industry benchmark for value-engineered zone sound systems. By seamlessly merging our powerful, open-architecture DSP functionality paired amplifier per- formance inside a two-rack space unit, PEMA lowers overall system cost, occupies less space, improves energy efficiency, and both speeds and simplifies system installation and programming. Four and eight amplifier channel versions are available at both 125 and 250 Watts per channel. Full 96kHz performance is available on 32-bit SHARC processors for utterly transparent audio.
