Rack mounting
VOLT is only one rack unit high, and can mount almost anywhere.
Like most sophisticated equipment, it can be damaged by extreme heat.
♦ Do not mount it directly above or below equipment that normally runs warm. For best
air circulation, make sure whatever is mounted below it is very shallow: a blank panel, or
something like a patchbay that doesn’t generate heat.
♦ Do not block the ventilation grills on VOLT’s sides. There should be at least an inch of air
space on both sides of the unit. Most racks provide this.
♦ Do not block the ventilation holes on VOLT’s back.
There’s a lot of electronics in VOLT’s chassis, so it has to be fairly deep: about 11½” plus con-
nectors. While it’s not particularly heavy, that depth has to be cantilevered by the one-unit front
panel: To prevent damage to the front panel, always mount with four rack screws. If you must
use only two screws temporarily, use both bottom screw holes. That distributes the weight better.
Live studio?
VOLT does not have an internal fan, and can be located near a live mic. This makes our HD Pro
DSP|Core version ideal for high quality podcasting and other small operations.

Audio connections
We designed VOLT’s audio routing to be extremely flexible:
♦ You can connect VOLT via balanced analog, AES/EBU digital, or Livewire AoIP. Each
input can have a different program stream, and you can select which input gets broadcast
on the front-panel LCD or from a connected computer. You can also designate one input
for automatic or manual “failover” backup of the same programming, if the main link is
disrupted.
♦ Each input and output can be adjusted independently: you can set any level between -12
and +12 dB of nominal, or trim the channel balance ±3 dB, in precise .1 dB steps.
♦ Each input can also be adjusted independently for polarity

with normal or inversion on
either or both input channels. Input signals can be independently set for normal L/R or
flipped R/L stereo, or mono from either channel or both summed.
