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.
PEMA changes the way consultants and integrators approach
sound system design. With only the addition of input sources
and output speakers, PEMA delivers an elegant solution with
less cabling, less rack space, and less installation time, using
proven DSP and amplifier technology that will awe clients
with its simplicity, sophistication, and reliability.
In addition to DSP algorithms such as ambient noise compen-
sation, advanced automatic feedback suppression, automatic
mixer, and a full complement of filters, EQs, delays, and the
like, PEMA offers DSP control of the amplifier functionality
as well: selection of bridge-mode operation, HPF settings for
constant voltage system networks, stereo-linking of channel
pairs, MIC/LINE/TEL-PAGE functions on channel 1, full control
of ducking priorities, and full-range remote-gain control
capability.
PEMA's I/O count and formats are ideal for small to mid-sized
installations. Each variant has eight balanced input channels
that are software selectable for mic or line levels. The first
channel may also be set for a transformer isolated, TEL-PBX
level. Additionally there are eight pairs of summed-mono RCA
connectors optimized for consumer line level devices. Eight
preamp auxiliary outputs allow integrators to route
signals from the matrix mixer to anywhere the system
requires.

As a member of the respected Protea™ DSP lineage,
PEMA is remarkably easy to program and deploy. All set
up is accomplished using standard 10/100 Ethernet
protocol and our Protea™ ne Software on a PC platform.
Hot-plug DSP placement allows users to insert any function
into any channel block, even when running live audio.
Automatic DHCP network IP configuration reduces network
set up time. Lockable front panel controls and multi-level
software security with password access guarantee a tamper-
proof audio system.
