Omnia Volt User Manual

Insert Points [sometimes called “Patch Points”]
Normally, all of VOLT’s audio outputs will carry the fully processed output
9
. You can use them
to distribute analog to nearby monitors, for example, while sending digital audio to a control
room via AES/EBU or Livewire.
However, you can also break VOLT’s internal signal path for use with a third party watermark
identification or EAS generator, or for our 25-Seven Voltair watermark enhancement and man-
agement system. This lets you optimize your program stream for the most reliable encoding.
♦ The external device will be fed from VOLT’s multiband Limiter, after all enhancement and
AGC. This way, watermark encoders can take advantage of Omnia presets that boost the
critical frequencies for electronic ratings systems.
♦ The external device or Voltair output is applied directly to VOLT’s drive control of the
final clipper or limiter
10
. This way, you don’t have to worry about an encoder’s added signal
driving your transmitter into over-modulation.
VOLT’s insert output becomes the “send” for your external device, and can be any one of
VOLT’s three audio outputs. The insert input (“return” from the external device) can be any
input you’re not using for the main program input stream or secondary [aka “failover”] backup
source. Insert input and output don’t have to be the same mode—one can be analog, for example,
while the other is AES/EBU—though this rarely occurs in practice.
Insert points are configured using VOLT’s network Remote Control. See that chapter for details.
Analog connections
These are balanced input and output, +4 dBu nominal. At nominal level, there is +18 dB of
headroom available.
Inputs can be fed from any transformer or electronically balanced sources. The input impedance
is 10kΩ. Outputs are electronically balanced, for any load of 600Ω or higher.
We do not recommend using VOLT in an unbalanced environment. If you must hook it up to
unbalanced equipment, use a buffer amp or transformer.
Connectors are standard XLR-3 male and female: pin 1 ground, pin 2 “hot”, pin 3 return.
AES/EBU connections
Input is stereo; transformer isolated and balanced 110Ω nominal per AES/EBU standard; 24 bit
resolution. Input automatically locks to any sample rate between 32 kHz and 96 kHz.
Output is stereo per AES3 professional standard; transformer isolated and balanced 110Ω
nominal. Output sample rate can be locked to the input, locked to an external sync source, or
use VOLT’s internal 48 kHz clock. AES/EBU output level is -18 dBFS nominal; like all VOLT’s
outputs, it can be adjusted over a 24 dB range.
9 VOLT: SG is designed for advanced FM Stereo generation at the transmitter, with a separate audio processor
feeding it (usually via an STL from the station). It does not do any internal audio processing. Its audio outputs
monitor the input signal, and input level adjustment or de-emphasis being applied.
