Key CPS Amplifier Product Features
Feature Benefit
Protection and
Safety
Over-temperature
protection
Ensures that the amplifier will never reach a critical
operating temperature thus preventing any thermal
damage. (includes a probe at the transformer too)
DC protection Eliminates amplifier damage in case of direct shorts
Excessive Back-EMF
monitor
Eliminates amplifier damage from reverse current flow
back into amplifier due to speaker failure
Low ac line voltage
monitor
Prevents amplifier performance problems and
potential speaker damage in case of AC line “Brown
Outs”
Front-to-Rear-Cooling
(3-step fans)
Draws "cold" air from outside the rack, fan is only
active(audible) when amp's working heavy.
Audio
Performance
Nonlinear signal monitor
(Dynamic Limiter)
Limits amplifier distortion to under 1 percent to
eliminate “hard edged” clipping and provide higher
average volume level.
Power Supply design
specially made to deliver
high peak signals
Live music and voice signals contain very high peak
transients compared to the much lower average signal
level. The CPS series have Burst signal outputs of:
CPS1: 640W, CPS2: 880W
Reliability Quality from Design to
manufacturing
3 year warranty
ProAnnounce Digital Routing System
Overview
This extraordinarily flexible and versatile system allows the configuration of either small or
complex installations. Most functions are realized through software modules, which - when
compared to conventional PA-systems – not only reduces the amount of cabling but also the
costs. Next to extensive audio signal generating and distribution functions, the ProAnnounce
system provides ample control functions. On one hand, these functions offer the possibility to
register and rate external events, as well as to control different external components, on the other
hand. Boolean operations and relations to the internal state of the system can be programmed as
well.
The digital ProAnnounce manager DPM 4000 represents the central unit of the system. It is used
to control and monitor all connected components via several serial interfaces.
The kind and amount of connected audio sound sources, amplifiers, and relay board assemblies
are extremely variable. This allows configuring the system to basically match any requirement.
The system is capable of managing up to 16 paging stations and up to 100 output lines. More
than 150 control inputs and outputs are available for controlling and monitoring purposes
providing the possibility to generate and manage logic levels and analog levels as well.
Configuration and documentation of a ProAnnounce system installation is established through the
use of the ProAnnounce Designer software – a comfortable graphical user interface that runs on
a PC under Windows. This allows changing the system’s setup at any time to meet new
requirements, without the need to alter the actual installation. The PC has to be connected to the
system only when loading or changing its configuration. During normal operation, PC-interaction
is not necessary. Anyway, in most cases the permanent connection of a computer bears benefits,
like displaying detailed status reports or the printing of protocols. It also offers the possibility for
remote diagnosis and remote maintenance via modem.
