POWERSUB 312
37
The PowerSub 312 powered
12“ subwoofer, which is equipped
with an integrated three-channel
Class D power amplifier with a
total output of 1300 W / RMS,
was specially conceived to permit
the swift and simple creation of a
subwoofer satellite system.
As satellites, two passive loudspeaker
systems such as the DYNACORD
D 8 are needed. You only need to
connect them to the Speakon out-
puts provided for the purpose. The
„X-Over“ switch offers a choice of
three discrete frequencies for the
crossover between the subwoofer
and the satellites: 70 Hz, 100 Hz
and 140 Hz, whilst the „Sub Level“
control allows you to adjust the output
of the PowerSub 312 in the range
from -8 dB to +10 dB. The PowerSub
312 is made from multiplex birch
plywood and capable of withstan-
ding the toughest challenges during
transportation as well as in use.
The integrated lightweight 800 W +
2 x 250 W digital power amplifi er is
perfectly attuned in every respect
to the integrated DYNACORD DND
12S400 woofer to maximize the dy-
namic range and audio quality and
ensure that the woofer is invariably
driven within its optimum working
range.
To provide further assurance that
these operating limits are respected,
the performance is supervised by
additional protective circuitry such
as voice coil protection, DC / HF pro-
tection, audio limiters, back EMF
protection and thermal protection.
Together these ensure that even
when the most extreme demands
are placed upon the system under
the most unfavorable conditions,
the PowerSub 312 continues to
operate fl awlessly. The use of
„Class D Digital Technology“ ensures
that there is considerably less power
dissipation than in normal Class AB
designs. The thermal load on the
components is therefore markedly
reduced.
The enclosure is coated with 2K
lacquer, which is extremely scratch-
resistant and proof against rough
handling during transportation.
A robust, powder-coated steel
grille protects the woofer against
mechanical damage. All the control
elements are recessed to provide
optimal protection of the Power-
Sub 312’s most sensitive parts even
during transportation. For greater
carrying comfort, the enclosure is
furnished with two sturdy handles,
whilst an integrated threaded pole
adaptor allows you to make optimal
use of precious space on stage.
