VOLT PROCESSING
Preset strategy and tuning
Before listening to presets, make sure input levels are correct. You can measure and adjust them from
the front panel or the Remote Control.
VOLT is designed to be used at -12 dBFS nominal; this is the level corresponding to “0 VU” on a
conventional analog meter. Adjust transmitter modulation and any subcarrier according to your
normal practice.
Don’t skip this step, and don’t try to over-drive VOLT’s input in hopes of “more density”. VOLT can deliver
all the density any station could ever want, while using proper input levels. Over-driving VOLT (or any
other equipment) only adds distortion.
After fine-tuning thousands of Omnia installations, we’ve developed a strategy for getting the
best results. Here are the principles:
Work offline
We recommend you experiment with VOLT’s presets and controls before putting it in your
airchain; that’ll give you the most freedom to try different things
16
. Hook it up to a program feed
and listen with good monitor speakers. You’ll be able to audition every preset, and turn every
control to its extreme, without annoying listeners.
Pick a preset.
Don’t get hung up on preset names.
Our names might imply specic formats or eects, but that’s often so our preset designers can keep
track of them. TalkInYourEar might work with some music format, and HotWire can work with news.
So try a bunch: it takes just a moment to load each preset, and loading doesn’t interrupt signal ow.
In fact, listening to all of the included factory presets is the best way to get a feel for what VOLT
can do. Decide which is closest to the sound you want, and use that as a starting point. Many
users like to play with VOLT in their shop before racking it: they feed typical program material,
try the controls, and audition all the presets. It’s a good idea.
There’s a complete list of presets later in this chapter.
16 Feel free to install VOLT in your rack before doing oine experimentation, if you’ve got a way to send its
output to good speakers in a quiet room. You can do all the preset selection, QuickTweaking, and deep tuning
by remote control.
