PRELIMINAR
Y
Electro-Voice ® , an industry pioneer –
still setting standards in
professional sound reinforcement
Over the last 75 years, EV ® has become one of the
leading manufacturers on pro audio. More than 50 years
experience in design and manufacturing of transducers,
systems and power amplifiers combined with the heritage
of nearly 30 years in digital signal processing are the
foundation for state-of-the-art audio performance. The
very close relation of the EV
® design team with customers
around the world is the basis for optimized system solu-
tions. It’s the unique combination of audio quality, relia-
bility and ease of use that is exceptional. Backed-up with
one of the largest dealer and service networks in the pro
audio world an EV
® system represents outstanding value.
Line-Array Systems
from Electro-Voice:
A true advantage
Line array’s have been known in the industry for
several decades, during the last five years they have
become the standard for concert and touring applications
and also very popular for installed sound systems. Today
there’s a large number of manufacturers offering “line
arrays” – a vertical array of loudspeaker cabinets. But not
everything that looks like a line array behaves correctly as
one. Electro-Voice
® ’s X-Line and XLC (X-Line Compact)
have been proven in countless events to have “true line-
array” behavior: a very well behaved horizontal disper-
sion and a very even front-to-back coverage. With X-Line
Very Compact, EV
® engineers have defined a new group
of very compact, high performing line arrays.
The “Hydra” –
EV ® ’s plane wave generator
The most critical information in any music signal is in
the mid and high frequencies and the number of HF
devices is still a “measure” to determine, whether the size
of a sound system is adequate. In a vertical array of mul-
tiple sound sources it is vital to maintain the distance
between the elements to be “small” relative to the radi-
ated wavelength. While this is far less complicated for
lower frequencies, the challenge is to couple frequencies
above 3kHz (wavelength about 11cm, or 4 inches) in
equal amplitude and phase in order to generate a “plane
wave”. A key component for the outstanding perform-
ance and success of EV line arrays is the unique design of
the “Hydra”. The signal from one HF driver is divided into
discrete paths arriving with same amplitude and phase at
the waveguide as a plane wave. This solution has much
lower distortion than many other designs.
The Hydra™ equalizes the path length to ensure equal
arrival times at the exit, which is necessary to create a
plane wave.
