Pro-balanced signal to hi-

The Iso•Max DIN-PC is perfect for situa-
tions where you need to send a pro-bal-
anced signal to a stereo hi- type input.
Simply connect to the balanced inputs
and output the -10 dB signal to feed the
hi- system.

The Iso•Max DIN-PC is a single channel pro-to-consumer isola­tor that is used to convert a +4 dBu line-level device to -10 dBV
for consumer-level signals such as connecting the balanced
output from a mixing desk to the unbalanced input of a hand­held video recorder or laptop.

The design begins with a gray molded assembly made from
UL94-VO ame retardant Noryl that snaps into place onto
a standard 35 mm DIN rail for easy installation in a NEMA
enclosure. Connections to and from the module are made
via removable screw-down wire terminals. Plug and play easy
to use, this passive interface does not require any power to
work. Inside is a Jensen high performance transformer that is
able to withstand signal levels to +21 dBu at 20 Hz without dis­cernible distortion. This provides galvanic isolation between
the input and output to eliminate hum and buzz caused by
ground loops, rejecting noise by as much as 120 dB.

Made for the most demanding professionals, the DIN-PC
delivers a ruler at response from 10 Hz to 140 kHz with less
than 2° phase shift at all frequencies. This makes the DIN-PC
ideal for converting balanced sources to unbalanced inputs
for large scale installations in performance venues, broadcast
houses and AV systems.

Applications

DIN-PC with a laptop

Use the DIN-PC to convert the balanced
line level output from your mixing
console to the unbalanced input on your
laptop or sound card. The DIN-PC will
manage the signal while eliminating hum
and buzz caused by ground loops.

Audio interface for video camera

Capturing a live performance is easy
using the DIN-PC as the audio interface
between the mixing console and your
video camera. Connect the console to the
balanced inputs and send the unbal­anced outputs to your camera.
