Dual Analog Audio Cable for
Line Level Applications
Belden’s new
Dual Line Level
Audio cable
features dual pair
construction in
different color
combinations for
stereo applications.
NP 151
elden has added a new
analog audio cable to its
complete audio cabling
offering that is essentially a
Siamese version of the popular
9451 single-pair construction:
Belden 9451D.
B
Professional audio environments
require permanent and semipermanent multichannel line
level installations. Such audio
applications use cables for
non-plenum areas behind walls
and in patch bay applications.
In conjunction to multipair snake
cables, individual pairs are the
common choice for carrying a
single audio channel to different
types of audio equipment.
Easy and Convenient
to Install
Belden 9451D becomes a
handy solution for wiring such
line level audio installations.
It features two single-pair cables
bonded together in a Siamese
construction, which eliminates
excessive tie wrapping needed
for single-pair constructions.
Its shield is bonded to the PVC
jacket, so both can be removed
simultaneously, reducing
installation time and
saving money.
Product Availability
Belden 9451D Dual Line Level
Audio cable is available in lengths
of 1000 ft. and 2000 ft. on a reel.
Belden 9451D is available
in four jacket color combinations.
This makes audio channel
identification easier before
and after installation.
Applications
Cabling professional recording
studios requires stereo wiring
(one single pair for each audio
channel). Normally, one shielded
twisted pair cable is used for the
right channel and a similar pair—
with a different jacket color for
identification—is used for the left
channel. Each audio channel is
color-coded based on user
preference. In audio studios,
several single-pair cables run
from racks to patch bays or
audio equipment, making
installation more complex
and cable identification more
difficult. As cable density
increases, cabling from these
racks to various pieces of audio
equipment becomes even more
messy and difficult to organize.
Construction Details
Belden 9451D features two
twisted pairs with (22AWG) tinned
copper conductors and polyolefin
insulation. Conductors are
color-coded red and black.
An aluminum-polyester Beldfoil
shield is bonded to the jacket for
easy termination. The foil shield
features a 22 AWG drain wire
inside the shield. Each pair has
a PVC jacket and is joined in a
Siamese construction.
Four jacket combinations are
available: Red/Green, Red/Black,
Red/Gray, and Red/Purple.
This cable is NEC and
CEC CMR rated.
