Architects' and Engineers'
Specifications
The unit shall be a two-in/four-out digital
loudspeaker system processor, configurable
for two-way stereo, two-way dual mono,
three-way mono, and four-way mono opera-
tion. The three-way configuration shall have
a separate full-range direct out and in this
configuration both the low and direct out-
puts shall be optionally set to be the sum of
two input channels. Each output shall be
mutable.
Functional blocks shall include: high- and
low-pass filters with Bessel, Butterworth and
Linkwitz-Riley characteristics, 6-, 12- 18-
and 24-dB-per-octave slopes and variable
corner frequencies; tunable low-cut filters
with Q variable from 0.5 to 2.0, 6- or 12-
dB-per-octave slopes and variable corner fre-
quencies; parametric equalizers with Q vari-
able from 0.4 to 20; low- and high-shelving
equalizers with 6- or 12-dB-per-octave
slopes and variable corner frequencies; out-
put limiters with adjustable threshold, decay
rate and hold time; and signal delays on the
input and on each output with a delay reso-
lution of 21 µsec and ranges of 2 to 1,000
msec on the inputs and 0 to 10 msec on the
outputs.
The unit shall have factory presets for at least
16 Electro-Voice brand loudspeaker systems.
All parameters shall be fully accessible in a
full-edit mode and storable in up to 10 user
memories in each of the three configurations
(two way, three way and four way).
The unit shall have a lock mode to prevent
unauthorized changes.
Inputs and outputs shall be electronically bal-
anced 3-pin XLR connectors, pin 2 positive.
Internal receptacles shall be provided for ret-
rofitting optional TRB-5 input and TRB-4
output transformers. The unit shall contain
linear 18-bit A/D and D/A converters. The
internal format shall be 24 bits. The unit
shall meet the following performance speci-
fications: frequency response, 20-20,000 Hz
±0.3 dB; signal-to-noise ratio, >102 dB;
THD, <0.01% at 1,000 Hz; nominal input
and output voltages, +4 dBu (1.23 V); maxi-
mum input and output voltages, +21 dBu (8.7
V); input impedance, 20,000 ohms; output
impedance, <100 ohms; and minimum load
impedance, 600 ohms.
The unit shall operate on voltages from 90
V to 250 V ac, 50 to 60 Hz, without adjust-
ment. Power consumption shall be 21 watts
maximum. The unit shall be manufactured
in accordance with all safety classes and ful-
fill all applicable interference suppression
approvals (IEC and VDE specifications).
The unit shall be rack mountable in one EIA/
IEC standard rack space. Dimensions shall
be 43.6 mm (1.75 in.) x 483 mm (19.0 in.) x
287 mm (11.3 in.) hwd. Net weight shall be
4.0 kg (8.8 lb).
The digital loudspeaker processing unit shall
be the EV Dx34A.
