music peak
Nominal radiation angles: 100˚
horizontal by 30˚ vertical
Transducer complement: 12”
Neodymium Dual Voice Coil Scorpion ®
woofer, Model SDC1288 and RD ™ 2.6
with 4.75” long aluminum composite
ribbon tweeter
Box tuning frequency (Fbox): 61 Hz
Electroacoustic crossover
frequency: 2,000 Hz
Crossover type: Internal Electronic
two-way crossover with driver EQ, level
matching, bass boost and subsonic
filtering.
Crossover Slopes: 24 dB/octave
(fourth order) low pass, 24dB/octave
(fourth order) high pass, both with
staggered poles and driver EQ. Unit has
horn spatially aligned with woofer, so
there is no need for phase alignment or
time delay of the signals.
Electronic Input Impedance
(Nominal):
10 k ohms unbalanced
20 k ohms balanced line level
2.4 k ohms balanced mic level
Input Connections: Input 1: One
combo female XLR/ 1/4” phone jack
providing balanced operation, with
switch-selectable mic- or line-level
sensitivity.
One 3-conductor balanced Euro-style
jack connector
Input 2: One combo female XLR/
1/4” phone jack providing balanced
operation, with switch-selectable mic-
or line-level sensitivity.
Two RCA phono-type jacks, which are
buffered and mixed to monophonic
for a summed signal. These are NOT a
stereo input, as the Impulse ® 12D is a
single full-range sound source.
Output Connections: One male XLR
balanced output, one ¼” TRS balanced
phone-type jack, one 3-conductor
balanced Euro-style jack connector.
Cabinet material: Injection-molded
polypropylene with internal ribbing
and bracing, and with textured finish.
Molded material is dark gray, as is the
metal grille. Available in a white version
as well.
Mounting: Subwoofer pole-mounting
or speaker stand via molded-in pole
mount, flying via Versamount ™ 70+, and
4 rubber feet for floor or stage use.
Dimensions: H x W x D
Front: 24.89” (63.2 cm) x 15.63” (39.7
cm) x 15.38” (39.1 cm)
Rear: H x W 23.13” (58.8 cm) x 7.50”
(19.1 cm), 13.50” (34.3 cm) at second
angle break
Weight: 39 lbs. (17.7 kg)
ELECTRONICS AND AMPLIFIER
