The eight-band limiters are equipped with fully adjustable thresholds and attack and
release times for each of the bands. Because the VP-8
iP
limiters operate with preci-
sion, time-aligned bandpass filters, its dynamic operation is nearly invisible to the ear.
The resulting on-air sound can be carefully tailored to create exactly that desired. The
eight bands of peak limiting utilized in the VP-8
iP
allows tuning flexibility previously
unheard of in any broadcast audio processor. The eight-band limiter section is followed
by its own four-band parametric equalization stage that can be used to further fine tune
the sound of each signal path.
The FM signal path is equipped with an adjustable diversity delay of up to ten sec-
onds, corresponding to the requirements of the North American (iBiquity®) HD Radio
system. A reference-grade stereo encoder is also available in FM mode to provide the
highest possible quality on-air signal.
Rack Mounting
The VP-8
iP
is designed to fit into an industry standard 19" equipment rack, and
requires one rack unit (1.75 inches) of vertical space. The VP-8
iP
has a depth of 14"
behind the rack rails (including chassis connectors). An additional five inches of space
is required for wiring cables to pass through. The chassis has a width of 17-3/8". Space
needed in front of rack rails is 3/4". Ideally, four screws should be used to mount the
unit. If only two screws are being used they must be used in the bottom holes in order
to provide proper support.
The VP-8
iP
does not have top or bottom cover vent holes. Latent heat is vented
out of the enclosure by natural convection through slots in the top of the rear panel.
Cooler air is drawn into the unit through vertical slots positioned lower in the side
panels. There is no fan inside the VP-8
iP
because its power consumption is low enough
to not require one.
The VP-8
iP
may be mounted between other devices in the equipment rack and
in accordance with good engineering practice should not be mounted directly above
devices that generate significant amounts of heat. If such a location is unavoidable
then it is advisable to utilize an extra 1RU blank rack panel between the VP-8
iP
and
devices immediately above and/or below it.
WARNING!
Under no circumstances should the VP‑8
ip
unit be opened! The
unit contains high voltage circuits that are hazardous and potentially harmful.
The unit has no user‑serviceable parts inside! If you have a problem the unit must
be returned to Wheatstone Corporation for repair.
Installation Tips:
• Place any surge protection circuits as close as possible to the VP-8
iP
or other
device being protected.
• Establish a low impedance common ground in your facility and try to route all
grounds to that point.
• Choose the best power conditioning / UPS units that you can afford and suitable
for your equipment – focus on the features and options you need. The better UPS
products can prevent thousands of dollars in equipment damage – some even come
with an external equipment damage warranty.
