AUDIO PERFORMANCE, REMOTE CONTROL AND
SUPERVISION AT THE HIGHEST LEVEL
Electro-Voice is famous for its 75 years of experience in designing
and manufacturing loudspeakers and microphones. Many audio
professionals, however, don’t know that it also has 50 years of
design experience in power amplifiers and more than 20 years in
digital audio processing.
An unwavering commitment to satisfying customer needs made
Electro-Voice a leading manufacturer of sound reinforcement
systems for stadiums, arenas, multi-purpose venues, theatres and
cinemas around the globe. Due to their sonic purity and extreme
reliability, EV's amplifiers became established with top concert-
sound and professional installation projects worldwide. The
Precision Series is the flagship of EV's amplifier line. They employ
the highest levels of design to meet the highest levels of demand.
EV’s new DSP-Controlled P-Series amplifiers combine legendary
performance with uncompromised remote control and system
supervision capability. They use EV’s state-of-the-art signal
processor technologies, and they guarantee superior audio
performance.
The network of the DSP Controlled Precision Series amplifiers is
controlled via a serial CAN-Bus. Up to 100 amplifiers, over a 1,000
m cable length can be controlled per CAN bus. USB to CAN
conversion is realized with the UCC-1 converter. Network cabling
is based on CAT-5 with RJ-45 connectors; each amplifier features
one input and one output. The audio monitor signal is available on
the XLR connector of the UCC-1.
Controlling more than 100 amplifiers requires another CAN bus.
At this time the control software is able to deal with a maximum
of 250 amplifiers in total. A significant advange of this architecture
is the ability to connect additional control PCs at any position in
the network. The software is able to handle several users, with
discretionary access control.
The DSP of each amplifier stores up to 8 user presets. This allows
system operation, independent of the network control in the
event of a network fault. All DSP settings (filter, eq, delay, level)
will stay in place. The other general-purpose amplifier inputs and
outputs may be used for network-independent preset switching.
For example, a dedicated emergency setting with maximum
power for the vocal band give a network of DSP-Controlled
Precision Series amplifiers the ability to meet highest security and
safety standards.
Remote control and supervision of up to 250
amplifiers via one or multiple PCs.
Central supervision of all amplifiers and connected
loudspeakers
State-of-the-art signal processing (Filter, Delay,
Level, Dynamics)
Display of the acoustical response of EV
speakers in real-time (RACE)
Integration with life-safety systems and control
of external equipment
Exceptional audio performance and extreme
reliability
