2.0kW Lightweight Power Amplifier
2.0kW Lightweight Power Amplifier
all kW Series amplifiers sets their performance
apart from other lightweight amplifiers. Two
switches on the rear of the amplifier select
the mode of operation of the processor and
a pole frequency that should be matched to
the tuning of a speaker system. This innova-
tive circuitry ensures that the transient re-
sponse of a speaker systems low-frequency
driver is accurately controlled and any phase
distortion is minimized. The three settings
available are LPN, B6 and Off. The LPN
setting is used for compact, vented speaker
systems other than those manufactured by
Electro-Voice. It is a second-order shelving
equalizer with a pole frequency of 50 Hz.
The B6 setting is specifically for Electro-
Voice speaker systems and supplies a 6 dB
boost at the selected pole frequency that is
flawlessly combined with an undamped
second-order high-pass filter to provide
maximum low-frequency impact and infra-
sonic protection. The B6 setting offers three
different peak-boost frequencies: 26 Hz, 43 Hz
and 60 Hz. The box tuning frequency of a
speaker system determines which pole fre-
quency is appropriate.
The 2.0kW has been evaluated and tested to
applicable ANSI/UL and CSA standards for
use in the U.S. and Canada. The NRTL/C mark
adjacent to the CSA mark signifies the prod-
uct meets applicable standards in the U.S. and
Canada.
The 25-pound Electro-Voice 2.0kW delivers
professional-quality amplification. Long-
term reliability and maximum portability
make this amplifier the foremost choice
among mobile sound professionals.
Architects’ and Engineers’
Specifications
The power amplifier shall be a dual-channel
model of solid-state design employing high-
power output devices in a true-complimentary-
symmetry output circuit. It shall be capable of
operating from a 120 V, 60 Hz or 220/240 V,
50 Hz ac line.
The amplifier shall contain sensing circuitry
to provide protection for the output transis-
tors against overtemperature, excessive out-
put voltage, radio-frequency interference,
shorted loads and excessive phase shift. The
load shall be similarly protected against start
up/shutdown transients, low ac line voltage,
and dc.
The power amplifier shall contain processing
circuitry that will ameliorate the phase and
transient response problems of the loud-
speaker. The built-in processor shall be ca-
pable of being adjusted for the enclosure type
and low-frequency characteristics of the
connected speaker.
Rear-mounted panel controls shall include
an input routing switch for selecting dual/
stereo or parallel mono operation and two
switches for control of the processor. The
processor controls shall include a switch for
turning the processor off and selecting the
enclosure type and three selectable frequen-
cies for B6 alignment of 60 Hz, 43 Hz and
26 Hz.
Front-panel indicators shall include power
on, peak, overtemperature, protect active,
and bridge-mode. Front-panel controls shall
include a power switch and level controls
that shall be detented potentiometers with
accurate markings.
The power amplifier shall meet the follow-
ing performance specifications: maximum
input voltage, 7.75 V rms; input voltage for
rated output power into 4 ohms, shall be
.74 V rms; rated output power per channel,
greater than 700 watts into 4 ohms from
20 Hz to 20 kHz at less than 0.10 THD,
greater than 450 watts into 8 ohms from
20 Hz to 20 kHz at less than 0.10 THD,
greater than 1,400 watts into an 8 ohm
bridged load from 20 Hz to 20 kHz at less
than 0.10% THD; hum and noise shall be
greater than 100 dB (A weighted) below
rated output power; frequency response
shall be 12 to 60 kHz, +0/-3 dBr, any mode,
at any output power up to rated output power;
damping factor shall be greater than 200 at
any frequency up to 1 kHz in dual mode with
an 8 ohm load; intermodulation distortion
(SMPTE) shall be less than 0.05% at rated
power in any mode into 8 ohms; operating
temperature shall be up to 50 °C ambient;
channel separation shall be greater than 50 dB.
Dimensions shall be (H x W x D): 88.9 mm
(3.5 in.) x 482.6 mm (19 in.) x 469.9 mm
(18.5 in.). Net weight shall be 11.33 kg (25
lb). Color: dark gray with white nomencla-
ture.
The 2.0kW has been evaluated and tested to
applicable ANSI/UL and CSA standards for
use in the U.S. and Canada. The NRTL/C mark
adjacent to the CSA mark signifies the prod-
uct meets applicable standards in the U.S. and
Canada.
