Electro-Voice SL10-2V User manual

Description
The Electro-Voice SL10-2V is a 15O slanted
baffle two-way, high-efficiency speaker
system. Its primary intended application
is for high-quality surround sound in small
and medium premium cinema installations.
It has been designed for high-power digi-
tal surround sound requirements usig
high-quality, professional-level compo-
nents such as a high-frequency 100Ox 90O
horn/driver and 10-inch woofer. the sleek
black-vinyl enclosure with a black cloth
grille attached with four screws has been
to blend into most interior design con-
cepts. A third-order (18-db-per-octave)
crossover at 1,500 Hz is used to combine
the two frequency sections and provide
the system equilization while achieving the
best directivity response both on and off
axis .
Frequency Response
The SL10-2V axial frequency response was
measured in Electro-Voice's large anechoic
chamber at a distance of 10 feet with a
swept sine-wave input , corrected to 1watt
1meter (see Figure 4). The responses
shows the ISO 2969 treble rolloff.
Directivity
The directional characteristics of the SL10-
2V wawe measured in Electro-Voice's large
anechoic chamber. The test signal was one-
third-octave pink noise at the frequencies
indicated. A full spherical measurement
system was used. All directional informa-
tion was measured at 20 feet. Figure 8 il-
lustrates the horizontal and vertical polar
responses. Figure 6 shows the horizontal
and vertical bandwidths. Beamwidth is the
angle at which the horizontal and vertical
polar respnses have decrease in level by
6dB when compared with the axial fre-
quency respnose.
Figure 7 illustrates the total directivity of
the SL10-2V. The directivity factor Rq(Q) is
the relative value, at a point, of an ideal
spherical response. The directivity index,
Di= 10log10Rq.

the most rigorous of power tests, but also
through continued use in arduous, real-
life conditions. The EIA Loudspecker
Power Rating Full Range (EIA RS-426-A
1980) uses a noise spectrum which mimics
typical music and test the thermal and
machanical capabilities of the components.
Electro-Voice will support relevant addi-
tional standards as and when they become
available. Extreme, in-house power test,
which push the performance boundaries
of the system, are also performed and
passed to ensure years of trouble-free ser-
vice.
Specifically, the SL10-2V passes EIA RS-
426-A 1980 with the following values.
RSR= (1.15 x REohms) , RE= 7.8 ohms
PE(MAX) =120 watts
Test voltage = square root of PE(MAX) x RSR
= 32.4 volts rms.
= 64.8 volts peak
The "peak power-handling capacity of a
woofer is deterimined by the peak test volt-
age amount. For the SL10-2V, a 64.8-volt
peak test voltage translates into an 480-
watt short-term-peak power-handling ca-
pacity. This is the equivalent of four times
the "average" power-handling capacity,

Uniform Limited Warranty Statement
Electro-Voice products are guaranteed
against malfunction due to defects in ma-
terials or workmanship for a specified pe-
riod, as noted in the individual product-
line statement(s) below, or in the individual
product data sheet or owners manual, be-
ginning with the date of original purchase.
If such malfunction occurs during the
specified period, the product will be re-
paired or replaced (at our option) without
charge. The product will be returned to
the customer prepaid. Exclusions and
Limitations: The Limited Warranty does
not apply to: (a) exterior finish or appear-
ance; (b) certain specific items described
in the individual product-line statement(s)
below, or in the individual product data
sheet or owners manual; (c) malfunction
resulting from use or operation of the
product other than as specified in the
product data sheet or owners manual; (d)
malfunction resulting from misuse or
abuse of the product; or (e) malfunction
occurring at any time after repairs have
been made to the product by anyone
other than EVI Audio Service or any of
its authorized service representatives.
Obtaining Warranty Service: To obtain
warranty service, a customer must deliver
and is a peak that can be sustained for only
a few milliseconds. However, this sort of
short duration peak is very typical in speech
and music. Provided the amplifier can re-
produce the signal accurately, without clip-
ping, the system will also perform accurately
and reliabilty, even at these levels.
Use in Cinemas
The SL10-2V has features which make it
particularly suitable for use as a cinema
surround sound, a black vinyl appearence
to complement most theaters interiors. The
high dynamics and power handling offered
by professional-grade components make it
especially suitable for digital surround
sound. The SL10-2V is THX®1 approved.
Suspending the SL10-2V
The SL10-2V was designed to be mounted
in a varity of ways using a varity of mounts.
There are three 5/16-18 diameter holes left
and right for horizontal or vertical mount-
ing using ALLEN PRODUCTS COMPANY
INC. (*****C Bracket) and four rear 1/4-20
